Embodiment Construction

[0015] Below in conjunction with embodiment further illustrate the present invention.

[0016] As shown in FIG. 1 , in an embodiment, the technical environment system involved in the method of the present invention includes a TV signal source, a broadband IP network, an on-demand server, a program storage, an IP set-top box and a user remote controller. The connection relationship of these devices is shown in the figure. Wherein, the on-demand server adopts a general server architecture, and the server also includes a channel recording CVR (Private Video Record). The concrete implementation steps of this method are as follows:

[0017] As shown in Figure 2, in the process of ordering, the user first passes through the electronic program menu in the IP set-top box displayed on the TV, and the user uses the remote control to issue selection instructions to the IP set-top box, and then the IP set-top box then selects the channels according to the channels selected by the user. ...

Abstract

The system comprises: program sources (TV station), wideband network, time- shifting server, program storage unit, IP set-top box and remoter controller of sending user request. The system combines the currently-used mass real-time storage technology with the video-on-demand (VOD) technology, and adopts the channel video recording technology to improve the disadvantage of the video-on- demand technology that is the TV program content is limited by the storage capacity and channel capacity. By the invention user can select the program contents in multi channels, which is provided by TV station in past time.

Description

Technical field: [0001] The invention belongs to the field of broadband digital television, in particular to a digital television channel ordering method applied to a broadband network. Background technique: [0002] According to the existing technical conditions, most of the TV broadcasting technologies can only realize multi-channel live broadcasting. For the so-called interactive TV, in terms of its functions, users can now implement video-on-demand on TV, but for these on-demand functions, there are great restrictions on users in terms of content and time. For example, the user can only order the content in the program menu broadcast by the TV station that day. Therefore, it is impossible for ordinary cable TV users to realize any time-on-demand viewing of TV programs through the functions of some technical products. Currently, there is no technical means to enable TV users to perform time-shifting (promptly time-reversing) on-demand services to past TV programs, so as...
