Embodiment Construction

[0020] In order to make the technical features and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] figure 1 As shown, the live server 4 of the present invention includes three parts: a main control module 1 , a live broadcast module 2 and a cache storage device module 3 .

[0022] Its concrete implementation scheme is as follows:

[0023] In the practical application of the present invention, the connected data source is a multicast TS stream. Since there are many channels, TS streams of different channels are sent to the same port with different IP addresses. Each channel has assigned IP address and port number like this, just can use IP address and port number to represent its channel of all live TV programs. The live broadcast server distinguishes and records different channels according to the IP address and port of the multicast TS stream, and the ca...

Abstract

The invention discloses a living broadcast server having the time shifting function and the implementation method thereof which are used in playing the digital television, wherein, the server comprises a master module, a living broadcast playing module and a buffer memory equipment module as well as the improvement and the innovation of related hardware and application software on the base of the prior channel-demand server. The equipment, through connecting a data source in the set-top box of the user, causes the user to have a wide range of opinions and to freely master the time for watching the program at any time on the programs of a plurality of channels provided by the television station in certain time in the past while extending the order TV program time of the user and the range of opinion on content, thereby compensating the regret that the wide televiewers miss wonderful TV programs.

Description

Technical field: [0001] The invention belongs to the field of digital television equipment, and in particular relates to a live broadcast server with time-shifting function applied to digital television broadcasting and an implementation method. 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 watchin...
