Control method for multicast service post-blockage and system thereof

Abstract

The invention discloses a control method for multicast service post-blockage, which comprises the following steps that: when the program with illegal content is blocked, a backup program is started, and the multicast address of the backup program is the same as the multicast address of the blocked program, and the source address of the backup program is different from the source address of the blocked program; the program steam of illegal content is continually transmitted on a monitoring interface, and a broadcast platform normally receives the program stream; and the backup program steam passes through a preset static route, and is transmitted on an user interface, and then, the user receives the backup program steam. The invention also discloses a control system for multicast service post-blockage. With the invention, the limit of illegal program can be realized, no any affect on watching television program by the end user can be caused, and the watching experience effect for the user can be ensured.

Description

technical field [0001] The present invention relates to the service control technology after the multicast service is blocked, in particular to a control method and system based on Internet Protocol Television (IPTV, Internet Protocol Television) after the multicast service is blocked. Background technique [0002] IPTV refers to a video service that is provided to users in an on-demand or multicast manner on a network based on Internet Protocol (IP, Internet Protocol). As a brand-new technology that provides home users with a variety of interactive services including TV content, IPTV is increasingly sought after by major telecom giants. It uses the telecom broadband network as the transmission channel and the TV as the terminal. It integrates various technologies such as the Internet, multimedia, and communication, and can effectively integrate the three fields of TV technology, Internet communication technology and personal computer (PC, Personal Computer). Combined, it g...

[0006] But in fact, the existing network deployment of the existing network, although the broadcast control platform can see whether there are illegal insertions, but once the illegal insertions occur, there is no flexible means to deal with them

If it is set through a data communication device such as a router, the channel is set to be illegal, so that the router will no longer forward its data stream. Although it can achieve the purpose of users no longer watching, there are obvious disadvantages: if the broadcast control platform is on the router Downstream of the device, after the router no longer forwards the data stream of the channel, the broadcast control platform itself can no longer receive the data stream of the channel and cannot monitor it; the broadcast control platform cannot see the data stream, so it cannot judge the channel in time When to return to normal, causing the channel to take longer to restore

[0009] In the prior art, the source of the program will be blocked after the non-government-approved content is found, but in the process of blocking the illegally inserted channel, no processing will be performed on the user side

Because the program that the user is normally watching is suddenly interrupted, the user will try to reconnect. If a successful response is still not obtained, it may cause user complaints and bring negative impacts on the operator; Operations such as reconnection, which also increase network overhead to a certain extent
