- Advertising costs are a serious concern for businesses creating digital content. For example, motion picture makers that sell their movies on DVD's incur great expense advertising the upcoming release of their movies. Similarly, video game producers spend lots of money advertising through magazines, television, the Internet, and other information channels to promote upcoming releases. In the same way, musicians and record labels expend great amounts of money advertising and promoting their newest releases. Advertising and promotion efforts represent significant costs to producers of commercial content. In addition to being costly, traditional advertising does not make purchasing the advertised material quick or easy. For instance, if television advertising is successful, the customer must still travel to a retail location, locate the item, and then purchase it. Depending on the circumstances of consumers, these additional steps may impede them from obtaining the advertised item.
- a person in a remote location may not have access to a store nearby that carries the advertised item.
- the consumer might not have access to adequate transportation to reach a store that sells the advertised item. If purchasing by mail or other delivery service, the consumer may be faced with a significant amount of time before he or she can receive the desired item. In any of the cases, the notion of having to wait so long to obtain the advertised item may discourage consumers to the point where they no longer wish to purchase the item.
- the present invention provides an optical disc and method for distributing protected content.
- Promotional content is provided on the disc in an area that is freely accessible by a consumer.
- the disk also has commercial content, such as a movie, that is accessible only after the consumer completes an activation process. More specifically, the commercial content is in an area of the disc protected by an optical shutter. In its initial state, the shutter interferes with the player's ability to read the protected data. But, after the activation process, the protected data is fully accessible. In this way, a single optical disc may be used to distribute free promotional content, as well as facilitate the selling of commercially valuable content.
- the disc may be a dual-sided disc, with the promotional content on one side and the protected commercial content on the other.
- the disc is a single-sided disc and the optical shutter a layer or other portion of the data, while other layers or portions are freely accessible.
- the commercial content in the protected data area is a full length movie.
- the promotional content in the unprotected data area is a theatrical trailer for the movie.
- the optical disc is sent to a consumer by the distributor of the movie. The consumer accesses the unprotected content and views the theatrical trailer.
- the consumer purchases information from the payment authority that is sufficient to cause the optical shutter to change states and allow access to the protected content. The consumer uses the information to cause the optical shutter to change states and accesses the full-length movie in the protected data area.
- the present system and methods enable a means of distributing and advertising commercial content on optical discs in a way that facilitates quick and easy purchase of the commercial content.

Abstract
Briefly, the present invention provides an optical disc and method for distributing protected content. Promotional content is provided on the disc in an area that is freely accessible by a consumer. The disk also has commercial content, such as a movie, that is accessible only after the consumer completes an activation process. More specifically, the commercial content is in an area of the disc protected by an optical shutter. In its initial state, the shutter interferes with the player's ability to read the protected data. But, after the activation process, the protected data is fully accessible. In this way, a single optical disc may be used to distribute free promotional content, as well as facilitate the selling of commercially valuable content.
Description
Optical Disc and Method of Distributing and Protecting Content
BACKGROUND
1. FIELD
[0001] This application claims priority to US patent application number 60/825,827, filed September 15, 2006, and entitled "Optical Disc and Method of Distributing and Protecting Content", which is incorporated herein by reference. The field of the present application is optical discs.
2. DESCRIPTION OF RELATED ART
[0002] Advertising costs are a serious concern for businesses creating digital content. For example, motion picture makers that sell their movies on DVD's incur great expense advertising the upcoming release of their movies. Similarly, video game producers spend lots of money advertising through magazines, television, the Internet, and other information channels to promote upcoming releases. In the same way, musicians and record labels expend great amounts of money advertising and promoting their newest releases. Advertising and promotion efforts represent significant costs to producers of commercial content. In addition to being costly, traditional advertising does not make purchasing the advertised material quick or easy. For instance, if television advertising is successful, the customer must still travel to a retail location, locate the item, and then purchase it. Depending on the circumstances of consumers, these additional steps may impede them from obtaining the advertised item. For example, a person in a remote location may not have access to a store nearby that carries the advertised item. In another example, the consumer might not have access to adequate transportation to reach a store that sells the advertised item. If purchasing by mail or other delivery service, the consumer may be faced with a significant amount of time before he or she can receive the desired item. In any of the cases, the notion of having to wait so long to obtain the advertised item
may discourage consumers to the point where they no longer wish to purchase the item.
[0003] Another feature common to many traditional forms of advertising is a compromised ability to target individual consumers in an engaging way. For example, television commercials are broadcast. The effectiveness of those television commercials depends greatly on the audience at a given time. It can be difficult to correlate the audience with a particular time slot. Further, television commercials suffer from the problem of having to distill a message down to just a matter of seconds. Similar problems exist for other advertisement channels. For instance, Internet advertising is only effective for people who use the Internet. While a growing percentage of the population may do so, a significant portion still does not use the Internet for commercial purposes or for purposes that easily facilitate advertising. Regardless, even if Internet advertising reaches its target audience, the amount of detail that can be included in Internet advertisements suffers from the same problems as television advertisement. Promotional information must be scaled back to fit in the limited, allotted space.
SUMMARY
[0004] Briefly, the present invention provides an optical disc and method for distributing protected content. Promotional content is provided on the disc in an area that is freely accessible by a consumer. The disk also has commercial content, such as a movie, that is accessible only after the consumer completes an activation process. More specifically, the commercial content is in an area of the disc protected by an optical shutter. In its initial state, the shutter interferes with the player's ability to read the protected data. But, after the activation process, the protected data is fully accessible. In this way, a single optical disc may be used to distribute free promotional content, as well as facilitate the selling of commercially valuable content.
[0005] In one example, the disc may be a dual-sided disc, with the promotional content on one side and the protected commercial content on the other. In another example, the disc is a single-sided disc and the optical shutter a layer or other portion of the data, while other layers or portions are freely accessible.
[0006] In one example, the commercial content in the protected data area is a full length movie. The promotional content in the unprotected data area is a theatrical trailer for the movie. The optical disc is sent to a consumer by the distributor of the movie. The consumer accesses the unprotected content and views the theatrical trailer. The consumer purchases information from the payment authority that is sufficient to cause the optical shutter to change states and allow access to the protected content. The consumer uses the information to cause the optical shutter to change states and accesses the full-length movie in the protected data area.
[0007] Advantageously, the present system and methods enable a means of distributing and advertising commercial content on optical discs in a way that facilitates quick and easy purchase of the commercial content.

[0014] Referring now to figure 1, system 10 for distributing and protecting content on an optical disc is illustrated. Generally, system 10 is useful for distributing and advertising commercial content on optical discs in a way that facilitates quick and easy purchase of the commercial content. System 10 has optical disc 12. It will be appreciated, that optical disc 12 may be a CD, DVD, gaming disc, Blue-Ray disc, HD DVD disc, or other optical media. It will be further appreciated that the present system and methods may be practiced with storage media functioning similar to optical discs. For example, the present systems and methods may be practiced with a medium which is read using electromagnetic radiation at frequency greater than optical frequencies. It will be appreciated that optical disc 12 may also be dual-sided or have information readable only from one side. Optical disc 12 has an unprotected data area 14. The structure of optical discs useful in system 10 is described in co-pending US provisional application 60/824,536 filed September 5, 2006 and entitled "Optical Disc with Shutter" which is incorporated in its entirety. Generally, an optical disc makes use of one or more data layers to store data. For example, a single data layer may be comparable to a 5-gigabyte layer used for storage according to a DVD5 standard. Other formats and capacities comparable to those in
standards such as DVD, Blu-Ray, HD DVD, and gaming discs may also be used. It will be appreciated, that unprotected data area 14 may comprise one or more data layers. In one example, unprotected data area 14 comprises a single data layer. It will also be appreciated that unprotected data area may comprise only a portion of a single data layer. In another example, unprotected data area 14 comprises two data layers which are both read from the same side of the optical disc 12. Unprotected data area 14 contains promotional content 15. It will be appreciated that promotional content 15 may include, but is not limited to, digital representations of movie trailers, commercials, advertisements, interviews, commentaries, documentaries, news stories, biographies, reviews, critiques, endorsements, previews, clips, plot summaries, credits, games, portions of games, games with reduced functionality or duration, software programs, portions of software programs, software programs with reduced functionality or duration, or music. Further it will be appreciated, that promotional content 15 may contain any content which may either directly or indirectly promote the acquisition of commercial content 13. For example, promotional content 15 may include a full-length movie which promotes the purchase of a sequel or other related movie.
[0015] Optical disc 12 also has protected data area 16. It will be appreciated that protected data area 16 may comprise one or more data layers of optical disc 12. In one example, unprotected data area 14 comprises one or more data layers read from one side of optical disc 12 while protected data area 16 comprises one or more data layers read from the opposite side of optical disc 12. In this case, optical disc 12 is a dual-sided optical disc. In another example, unprotected data area 14 comprises a data layer read from one side of optical disc 12 and protected data area 16 comprises a data layer read from the same side of optical disc 12. In this example, optical disc 12 could be a single sided optical disc. In another example, protected area 16 and unprotected data area may both be contained in a single data layer. Protected data area 16 contains commercial content 13. In one
example, commercial content 13 comprises a full-length movie. It will be appreciated however, commercial content 13 may comprise one or more movies, television programs, recordings of music, games, software programs, or other digital representations of content having commercial value. In general, commercial content 13 may comprise a digital representation of any information from which commercial value may be derived. In the preferred embodiment, promotional content 15 is related to commercial content 13. For example, commercial content 13 may be a full-length movie, while promotional content 15 may be advertisements and trailers created to promote the movie. In another example, commercial content 13 may be a fully functional software program, while promotional content 15 is a trial version of the software program. [0016] Optical disc 12 also has optical shutter 18. The configuration of an optical shutter is described in co-pending US provisional patent application 60/824,536. Generally, optical shutter 18 serves to restrict access to protected data area 16. In one example, optical shutter 18 is an electro-chromic material. The electro-chromic material can be configured to alternatively allow light to pass and reflect light coming from a reading laser. In one example, optical shutter is implemented on the surface of optical disc 12 and is positioned between the anticipated source of the reading laser and a portion of the protected data area. In another example, optical shutter 18 is formed inside optical disc 12. In a similar example, optical shutter 18 is formed as part of a data layer of optical disc 12. Optical disc 12 also includes RF chip 17. The construction and function of RF chip 17 as used herein is described in co-pending US provisional patent application 60/824,536. Generally, RF chip 17 is connected to optical shutter 18, and is capable of altering the state of optical shutter 18. For example, RF chip 17 can transmit a signal to optical shutter 18 causing it to switch from a state of reflecting light to a state of allowing light to pass through. It will be appreciated that RF chip 17 may have security features that restrict when it will cause optical shutter 18 to change state and allow access to protected data area 16. This
process of causing the optical shutter to change state to enable access to the protected data area 16 may be referred to as activation of the optical disc 12. In one example, RF chip 17 may maintain an activation key programmed into the chip at or after the time of manufacture. In this example, RF chip 17 will not cause optical shutter 18 to change state and enable access to protected data area 16 unless the chip receives the pre-programmed activation key. Highly secure, computationally efficient means for securing the activation process are described in co-pending US application 11/456,040 filed July 6, 2006 and entitled "Method for Authenticating and Securing Transactions Using RF Communication" which is incorporated in its entirety by reference. Similarly, the process for constructing an optical disc with an RF chip is described in co-pending US provisional application 60/824,536. Optical disc 12 also has antenna 19 connected to RF chip 17. Antenna 19 enables RF chip 17 to communicate with radio 21 on reader 20. [0017] System 10 has reader 20 for communicating with optical disc 12 via RF chip 17. Generally, reader 20 is used during the process of gaining access to commercial content 13 in protected data area 16 of optical disc 12. Reader 20 can read information from RF chip 17. This information may include information about the RF chip 17, the optical disc 12, the promotional content 15, the commercial content 13, the manufacturer of the disc, encrypted information, keys used in encryption, or other information useful in the process of enabling access to the commercial content 13 in the protected data area 16. Reader 20 can also transmit information to RF chip 17. This information may include, activation keys, encrypted information, encryption keys, or other information useful for the RF chip 17 in determining if the chip should cause optical shutter 18 to allow access to protected data area 16. It will be appreciated that these communications between RF chip 17 and reader 20 are enabled at the physical level by antenna 19 and radio 21. It will also be appreciated that the communications between RF chip and radio 21 may correspond to frequencies consistent with RFID, NFC, or other communication protocols. It will further be
appreciated that reader 20 may be any device capable of communicating with RF chip 17. In one example, reader 20 is activation enabled mobile phone. In another example, reader 20 is a stand alone activation device. In another example, reader 20 is an activation device integrated into some other product, such as a computer. Generally, it will be understood that an activation device or activation enabled device is a device that may participate in the activation process described herein and in co-pending US application 11/456,040. [0018] System 10 also has payment authority 22. Payment authority 22 represents the entity who controls authorization for access to protected data area 16. Generally, the creator or distributor of commercial content may establish the payment authority 22 to sell authorization to access protected data area 16. For example, having viewed the promotional content 15 on optical disc 12, a consumer may wish to access the commercial content 13. The consumer may conduct a payment transaction with payment authority 22 in which the consumer exchanges money for information sufficient to enable access to commercial content 13 on optical disc 12. More specifically, having viewed the trailer from unprotected data area 14, a consumer may wish to purchase access to the full-length movie in protected data area 16. The consumer contacts payment authority 22 and pays fifteen dollars for an activation key that will cause the RF chip 17 to cause the optical shutter 18 to allow access to the full-length movie. In another example, information sufficient to enable access protected data area 16 may be given away without cost to consumers for purposes of promotion or for other reasons. In another embodiment, after receiving payment, payment authority 22 may instruct network operation center 24 to give a consumer information sufficient to access protected data area 16. The process by which the consumer receives the information sufficient to enable access to the protected data area 16 will be discussed further herein. In one example payment authority 22 is an automated system. In another example payment authority 22 may be a collection of individuals who conduct payment transactions. It will be
appreciated that during the payment transaction, information from the RF chip 17 may be transmitted to payment authority 22. In one example, reader 20 is an activation enabled mobile phone. The consumer may use the activation enabled phone to read information from RF chip 17. The activation enabled phone can then be used by the consumer to contact payment authority 22. In another example, the activation enabled phone may automatically contact payment authority 22 after reading information from RF chip 17. In either case, the phone may be used to transmit information from the RF chip to the payment authority 22.
[0019] System 10 also has network operations center 24. Network operations center 24 manages the information necessary for RF chip 17 to cause optical shutter 18 to allow access to protected data area 16. For example, network operations center 24 may maintain a list of activation keys which, when transmitted to RF chip 17, will cause the RF chip 17 to cause optical shutter 18 to enable access to protected data area 16. In another example, network operations center 24 maintains information that is sufficient, when combined with information from RF chip 17, to generate information sufficient to cause RF chip 17 to cause optical shutter 18 enable access to protected data area 16. In general, after conducting a payment transaction with a consumer, the payment authority 22 will transmit information to network operation center 24 indicating that a particular consumer is authorized to access the protected data area of a particular optical disc 12. This information may include some or all of the information extracted from the RF chip 17 by the reader 20 and transmitted to payment authority 22 during the payment transaction, information about the consumer, or other information. It will be appreciated that the functionality of the payment authority and the network operation center may be accomplished by a single entity. In one example, reader 20 is an activation enabled mobile phone. After conducting the payment transaction, the consumer may use the phone to contact the network operation center 24. In another example, the activation enable
phone may contact the network operation center automatically after conducting a payment transaction. In either case, the network operation center transmits information to the activation enabled phone that is sufficient to cause the RF chip 17 to cause the optical shutter 18 to enable access to the protected data area. In one example, this information may be an activation key. In one example, the activation enabled phone may also transmit information to the network operation center 24 regarding the identity of the consumer, the RF chip 17 on the optical disc 12, or other information. After receiving the sufficient information from the network operation center, the activation enabled mobile phone, or reader 20 more generally, transmits the information to the RF chip 17. RF chip 17 causes the optical shutter to change state and access to restricted data area 16 is enabled. The consumer may now access commercial content 13. Advantageously the present system enables a simplified means for advertising and selling commercial content. Distributors can send optical discs that contain both advertisement and the advertised content to individual customers. Customers persuaded by the promotional materials can quickly and easily purchase the advertised content.
[0020] Referring now to figure 2, optical disc 50 is illustrated. It will be appreciated that optical disc 50 is similar optical disc 12 in figure 1 and to optical discs described in co-pending US provisional patent application 60/824,536. Given the similarities, optical disc 50 will not be described in detail. However, for purposes of limited description, optical disc 52 is illustrated as a enlarged replication of optical disc 50 with area 56 removed. Optical disc 52 has data area 66. Data area 66 may contain one or more data layers. Optical disc 52 also has lead in area 64 for use in reading optical disc 52. Optical disc 52 also has optical shutter 58. It will be appreciated that optical shutter 58 is similar to optical shutter 18 from figure 1. Optical shutter 58 may be composed of a material capable of alternatively interfering with and not interfering with the operation of a reading laser. In one example, optical shutter 58 is positioned in between the
anticipated source of a reading laser and a portion of data area 66 containing initialization information for optical disc 52. In this manner, optical shutter 58 can prevent a reading laser from being able to access information in data area 66. Optical shutter 58 is connected to RF chip 60. RF chip 60 is similar to RF chip 17 from figure 1 and will not be described in detail. RF chip 60 is connected to antenna 62. It will be appreciated that antenna 62 is similar to antenna 19 from figure 1 and will not be described in detail. In one example, the antenna 62 wraps, at least partially, around the center hole of optical disc 62. Advantageously, integration of optical shutter 58, RF chip 60, and antenna 62 into or on optical disc 52 enables the functionality of the systems described in relationship to optical disc 12 of figure 1.
[0021] Referring now to figure 3, optical disc 75 is illustrated. Figure 3 represents a cross sectional view of optical disc 50 from figure 2. Optical disc 75 has side one 77 and side two 79. The two sides correspond to opposite sides of a dual-sided disc. In the example illustrated, dual-sided optical disc 75 has two data layers on each side. Side one layers 87 and side two layers 89 comprise a total of four data layers of dual-sided optical disc 75. The process for manufacturing optical discs such as optical disc 75 are described in co-pending US provisional application 60/824,536. Generally, side one 77 and side two 79 are separated by bonding material 78. In one example, multiple types of bonding materials are used in fabrication of optical disc 75. Optical disc 75 has optical shutter 85 for alternatively interfering in allowing a reading laser to read one or more of the side one layers 87. When in an interfering state, optical shutter 85 reflects light from a reading laser and thus prohibits access to information contained on the side one data layers 87. It will be appreciated that in other configurations, optical shutter 85 may interfere by not reflecting light. For example, in a configuration where optical shutter 85 is formed as part of layer 1, it interferes with the operation of a reading laser by not reflecting light. Regardless of the state of optical shutter 85, side two data layers 89 may be
accessed by a reading laser. Optical disc 75 also has RF chip 81. RF chip 81 is connected to optical shutter 85 and can cause the optical shutter to alternatively interfere and not interfere with light from a reading laser. RF chip 81 is also connected to antenna 83. Antenna 83 enables RF chip 81 to communicate with external devices. Advantageously, the configuration of components represented in figure 3 enables the functionality of optical disc 12 as described in relationship to figure 1. Specifically, commercial material may be stored on the protected side one data layers 87. At the same time, promotional material may be stored on unprotected side two data layers 89. Consumers can freely access the material on side two, and if they desire to do so, quickly and easily purchase access to the material on side one. In another example, the optical shutter can be configured to permit and deny access to a subset of the layers on the same side of an optical disc. For example, and optical shutter could be configured to restrict access to layer one while permitting access to layer zero. Means for constructing such an optical disc are discussed in co-pending US provisional patent application 60/824,536. With such an optical disc, one or more data layers on one side of optical disc could constitute a protected data area while one or more data layers on the same side could constitute an unprotected data area. In this manner, a one-sided optical disc can also function in the manner described in relationship to figure 1.
[0022] Referring now to figure 4, method 150 for distribution and retail of digital content is illustrated. Generally, method 150 is useful for direct advertising that facilitates quick and easy purchase of digital content. Method 150 begins as a creator or distributor provides commercial content for a protected data area of an optical disc, as illustrated in step 152. It will be appreciated the commercial content may comprise one or more movies, television programs, musical recordings, games, software programs, or other digital representations of information that has commercial value. In one example, the optical disc is a dual-sided disc, and the protected data area comprises data layers on one side of
the optical disc. It will be appreciated the present method may also be applied to single sided optical discs. In that case, the protected data area would comprise one or more data layers on the same side of an optical disc as the one or more data layers comprising the unprotected data area. After providing commercial content for the protected data area of the optical disc, the creator or distributor continues by providing promotional content for the unprotected data area of the optical disc. Again, it will be appreciated that the promotional content may include movie trailers, commercials, advertisements, interviews, commentaries, documentaries, news stories, biographies, reviews, critiques, endorsements, previews, clips, plot summaries, credits, games, portions of games, games with reduced functionality or duration, software programs, portions of software programs, software programs with reduced functionality or duration, or music. In one example, the unprotected data area comprises one side of the optical disc. In another example, the unprotected data area comprises one or more data layers on the same side of the optical disc as one or more data layers comprising the protected data area. It will be appreciated that the promotional material may be any material intended to promote the use or value of commercial content either directly or indirectly. After providing both commercial content on a protected area and promotional content on an unprotected area of the optical disc, the optical discs are distributed to consumers as illustrated in step 156. It will be appreciated that any known form of distribution may be employed. For example, optical discs may be mailed to potential costumers. Advantageously, this method of distribution would enable distributors to identify and target individual customers. In another example, distributors may send a plurality of optical discs to a retail location or other facility such as a movie theater. The optical discs could then be handed out to customers or patrons. In one example a movie theater is showing the sequel of a movie already released on DVD. Optical discs containing the full-length version of the prequel in the protected data area can be distributed to movie-goers at the theater. In this manner,
persons viewing the sequel can easily and quickly purchase or obtain access to the prequel.
[0023] After distributing the optical discs to consumers, the distributors receive requests for access to the protected data area of an optical disc as illustrated in step 158. As described in relationship to figure 1, these requests may form part of a payment transaction. However, in other examples access may be used as a promotional tool, and payment may not be necessary. However, generally, it may be that in conjunction with a request for access to content on the protected site to disc, payment for access to the content on the protected data area of the disc may be received. After receiving a request, and possibly payment, the distributor provides information to the consumer that is sufficient to access the content on the protected data area of the disc as illustrated in step 160. As described in relationship to figure 1, this may involve the use of a network operations center which provides information used by the RF chip on the optical disc. After receiving the information, the RF chip causes the optical shutter on the disc to enable access to the protected data area. In this manner, the consumer may access the protected content. Advantageously, the present method enables distributors to advertise and facilitate purchase of advertised goods in a low-cost and personal manner.
[0024] While particular preferred and alternative embodiments of the present intention have been disclosed, it will be appreciated that many various modifications and extensions of the above described technology may be implemented using the teaching of this invention. All such modifications and extensions are intended to be included within the true spirit and scope of the appended claims.
