Description
Technical field
The present invention relates to digital television techniques field and video on demand techniques field, relate in particular to a kind of play-on-demand program system and method based on one-way set-top box.
Background technology
High definition and interaction have become the DTV Development Trend; Video request program (Video On Demand; VOD) be the important content that DTV is realized interactive service; VOD can provide better user experience, satisfies the demand of different user rating, is that DTV is realized one of important way that increment is taken in.Digital TV field mainly contains multiple VOD technology such as NVOD, IPTV, IP-QAM at present.NVOD plays video frequency program on a plurality of channels according to certain time interval simultaneously, and the user can watch nearby.NVOD adopts broadcast mode, does not have the concurrent user to limit, but broadcast items is not controlled by the user, can't satisfy the demand that user's own is selected program, and effect is relatively poor.IPTV utilizes computer network, the STB with network function request program and decodes and plays from the server, and the user is free to select program and carries out Play Control; It is real VOD technology; But owing to receive the restriction of the network bandwidth, video frequency program generally all adopts processed compressed, appreciates effect and reduces relatively; Especially the high definition program that occupied bandwidth is bigger is realized relatively difficulty on IPTV.IP-QAM pattern VOD has the STB of network function through IP network visit EPG server; Inquiry and request program; The VOD server sends to the program of program request the IP-QAM of STB affiliated area; IP-QAM equipment is broadcasted program stream modulation back in digital tv network, but the request program of STB rating.
No matter be IPTV pattern or IP-QAM pattern, all requiring STB is to have the network function bi-directional set-top box, and the one-way set-top box that does not possess network function can't be realized the VOD function of IPTV or IP-QAM mode.China's most of areas has been accomplished the DTV translation at present; But accomplish the translation area; Use the user of one-way set-top box to account for quite a few,, just must carry out the bi-directional set-top box upgrading if these one-way set-top boxes user wants to enjoy the VOD function of IPTV or IP-QAM mode; This will need a large amount of fund inputs, realize difficulty.This can't enjoy various facilities and the good experience that real VOD brings with regard to having caused at present a large amount of one-way set-top box users, and the DTV that has had a strong impact on the user is experienced, and has influenced the popularization of VOD service, has limited the income of operator.
Summary of the invention
The object of the invention is exactly that one-way set-top box can't carry out true VOD and problems such as difference are experienced in video request program in order to solve; A kind of play-on-demand program system and method based on one-way set-top box has been proposed; It can satisfy the demand that the one-way set-top box user carries out video request program; Make the one-way set-top box user can freely select program to carry out rating, obtain good DTV and experience, also can increase the professional profit brought of the VOD of operator simultaneously.
