Problems solved by technology
[0003] The all-IP set-top box generally adopts the http download mode when downloading upgrade files and advertisement resource files. It is difficult for general operators to meet this bandwidth requirement
Although it is possible to allow users to download in batches through the distribution mode, for operators with millions of users, the timeliness of updates is not enough, which also greatly affects business operations
[0004] In addition, there is a problem with the update timeliness of the program list of the channel. If the program list update is to be notified to the user in real time, if the client requests the server through the http interface protocol in real time, then the number of concurrent accesses to the server interface is extremely high, which will cause catastrophic access. shock

A file distribution system through a multicast channel, including a file distribution initiator, which receives a file distribution receiving client's download file request, and sends the entity file distribution request to a distribution scheduling management system; the distribution scheduling management system, which according to Entity file distribution request, schedule management of distribution tasks, and send the distribution schedule to the instant messaging service and the file distribution multicast sending service respectively; the instant messaging service notifies the distribution schedule to the file distribution receiving client ;File distribution multicast sending service, which uses multicast channels to distribute specified files or materials to file distribution receiving clients according to the distribution schedule. The invention also provides a file distribution method through a multicast channel, which reduces the access pressure and service bandwidth pressure of the server and saves network resources.
Description
technical field [0001] The invention relates to the technical field of IPTV, in particular to a system and method for file distribution through a multicast channel, which solves the access pressure brought by a set-top box / smart TV to a server when downloading various resource files. Background technique [0002] With the rapid development of Internet technology, broadband technology, and streaming media technology, all-IP-based set-top boxes and smart TVs are going to thousands of households. When set-top boxes / smart TVs download upgrade packages and request video advertisements, especially high concurrent users during peak hours Access, bandwidth and server access pressure is extremely high. [0003] All-IP set-top boxes generally use the http download mode when downloading upgrade files and advertising resource files. This bandwidth requirement is difficult for general operators to meet. Although users can download in batches through the shunt mode, for operators with m...
