Embodiment Construction

[0018] Below in conjunction with embodiment further illustrate the present invention.

[0019] As shown in Figure 1, in an embodiment, the system of the present invention includes a program source (TV station), a time shift 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 time-shift server adopts a general server architecture, and the server also includes a channel recording CVR (PrivateVideo Record). The specific working steps of the system are as follows:

[0020] The recording process of the TV program by the system:

[0021] As shown in Figure 2, through the connection between the time-shift server and the TV transmitting station, the server records the TV programs of all channels in the form of files and puts them into the program memory in time (the storage mechanism exceeds the limit of the file system, realizing large-capacity fast Storage), the process is to ...

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 to use the time index approach to replace the program content index such that users can watch the TV programs played in past time at any time.

Description

Technical field: [0001] The invention belongs to the field of digital television, in particular to a time-shifting system applied to digital television broadcasting. Background technique: [0002] According to the existing technical conditions, most of the TV broadcasting technologies can only realize multi-channel live broadcasting. For viewers who missed the wonderful program of the day and want to watch it again, either wait for the rebroadcast of the program by the TV station (need to arrange a specific time to watch), or enjoy the on-demand service provided by the operator after the program is recorded (the prerequisite is that the operator must Recording related programs, and viewers need to accurately retrieve the content). This creates great restrictions on users in terms of content and time. Therefore, it is impossible for ordinary TV viewers (usually cable TV users) to realize watching TV programs at any time. At present, there is no system realized by a relativ...
