Embodiment Construction

[0036] An embodiment of the present invention provides a system for playing quasi-video-on-demand programs. The logic diagram of components of an embodiment of the system is shown in FIG. 3 , and the system includes: an IPTV application system and an NVoD server.

[0037] Described IPTV application system is used for creating NVoD channel, generates corresponding NVoD channel list that comprises whether NVoD channel supports time-shifting operation property information for IPTV user terminal, and supports IPTV user terminal in the multicast state of NVoD and the time shifting of NVoD ( Unicast) state switching;

[0038] The NVoD server is used to play the program specified by the operator according to the specified schedule according to the control of the IPTV application system; the playing mode includes: multicast mode and unicast mode. The NVoD server may be served by a VoD server, or may be a server dedicated to providing NVoD services. The NVoD server directly sends the ...

Abstract

A program playing system of quasi-video on demand program comprises network TV IPTV application unit for setting up NVoD channel and for generating relevant NVoD channel table according to information of set up NVoD channel, quasi-video on demand NVoD server being connected to IPTV application unit and being used to play program assigned by operation firm in multicast or in single cast mode according to control of IPTV application unit on specified time table.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an IPTV application system and a method and system for playing quasi-video-on-demand programs. Background technique [0002] In traditional analog TV, the user's viewing behavior is limited by the program schedule. Once the time is missed, the user can only wait for the TV station to rebroadcast the program. The above limitations do not change in unidirectional network-based digital television. [0003] With the extensive use of home video equipment and digital discs, the personalized video service-VoD (Video on Demand, video on demand, that is, users can freely specify the start time of the program, and use fast forward and rewind during the program playing. , pause, and locate) have become an important part of the average user's life. Obviously, introducing VoD services on digital TV is the general trend. But the unidirectional network limits the downlink bandwidth an...
