[0015] (Functional configuration of content playback apparatus)

FIG. 1 is a block diagram showing the functional configuration of the content reproduction apparatus according to the embodiment, which focuses on the present invention. First, the functional configuration of the content reproduction apparatus according to the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 1, the content playback apparatus 100 includes a user interface (hereinafter referred to as “UI”) 101, a content recording unit 102, a storage unit 103, a notification unit 104, an extraction unit 105, and a playback unit. Part 106.

UI 101 is an interface for exchanging information between content reproduction device 100 and a user of content reproduction device 100. The content reproduction apparatus 100 provides information to the user of the content reproduction apparatus 100 via the UI 101. A user of the content reproduction device 100 performs an input operation on the content reproduction device 100 via the UI 101.

Specifically, the UI 101 includes, for example, a display capable of displaying arbitrary information and an operation key for receiving an input operation by a user of the content playback device 100. The operation keys are realized by, for example, a plurality of button keys or a touch panel stacked on the display.

[0018] The content recording unit 102 records content. Here, the content is information for outputting sound such as music through a speaker, for example. More specifically, content means the power of a computer when outputting sound such as music, and it means to the user who is the target of sound output, not information such as programs that are meaningful to the computer. It is content information with.

[0019] The content is not limited to sound such as music. For example, images (video and static Includes still images. ) May be information representing an image portion displayed on the display when the image is displayed on a display controlled by a computer. Further, the content may be information including an image and sound. The content includes information such as programs that are meaningful to computers in addition to content information that is not limited to content information that is meaningful to humans.

The storage unit 103 stores content identification information and information related to the content attribute in association with each other. The content identification information is information that can identify each content. For example, the content identification information is information that identifies a recording medium on which the content is recorded and information that indicates a recording position of each content on the recording medium.

[0021] Information relating to content attributes is information representing classification items when content is classified according to various classification items. For example, information on content attributes is information that represents the genre to which the content belongs, the impression received from the content, the creation date of the content, the artist or creator of the content, the name of the recording medium on which the content is recorded, and the like. Specifically, for example, when the content is a content representing music, “Rock”, “Classic”, “Jazz”, etc. are information representing the genre to which the content belongs.

[0022] Also, specifically, for example, if the content is content that represents a song, information that represents an impression received from the content, such as “sounding song”, “bright song”, and “settled song”, is provided. Information about content attributes. Similarly, information representing content creation age, such as “1970s” and “1980s”, is information related to content attributes.

Storage unit 103 may further store information regarding the attribute of the content for each playback position in the content. Specifically, in the case of content whose attributes change depending on the playback position, such as music content that changes from major to minor, for example, a bright song in the major part and a “bad song” in the minor part. In this way, the content power and impression received vary depending on the playback position. In the case of such content, the storage unit 103 stores information on the attribute of the content for each playback position, together with information that can specify the playback position in the content. The notification unit 104 uses the information recorded by the storage unit 103 to notify information related to the attribute of the content being played back. For example, the notification unit 104 displays information related to the attributes of the content being played back by displaying various types of information representing the attributes of the content being played back on the display. The notification unit 104 constantly notifies information regarding the attribute of the content being played back during playback of the content. The notification unit 104 may notify the information related to the attribute of the content being played back only at a predetermined time before the playback start time or the playback end time of the content.

[0025] In the storage unit 103 described above, when information power regarding content attributes is recorded for each content reproduction position, the notification unit 104 uses the information recorded by the storage unit 103 to reproduce the content being reproduced. Information regarding the attribute of the content may be notified for each playback position in the content. When the information related to the attribute of the content being reproduced is notified by the notification unit 104, the user of the content reproduction device 100 uses the U 1101 described above to select one piece of information from the information notified by the notification unit 104. Perform the input operation to select.

In this case, for example, if the information power regarding content attributes is different for each content playback position, information regarding different attributes is broadcast even when a series of content is being played back.

[0027] When there is an input operation using the above-described UI 101, the extraction unit 105 is selected from the information notified by the notification unit 104 using the information recorded by the storage unit 103. Identification information associated with one piece of information is extracted. The reproduction unit 106 reproduces the content identified by the identification information extracted by the extraction unit 105, following the content being reproduced.

[0028] The reproduction unit 106 reproduces the content identified by the identification information extracted by the extraction unit 105, for example, by interrupting reproduction of the content being reproduced. Further, the playback unit 106 may play back the content identified by the identification information extracted by the extraction unit 105 after the playback of the content being played back is completed. [0029] Although illustration is omitted, the content playback apparatus 100 includes a display that displays various types of information representing the attributes of the content being played back, and is being notified by the notification unit 104 during playback. A list display unit is further provided that displays a list including information on attributes of other contents that have the same attributes as the content being played back for each piece of information on the contents attributes! /.

[0030] In this case, the list display unit displays, for example, a list including a plurality of pieces of information related to attributes of other contents having the same attributes as the content being reproduced. For example, the list display unit may display information about the attribute of the content being played back by placing the information at the approximate center of the list. In addition, the list display section displays information on the attributes of the content being played at the top of the list so that the list is displayed.
