Embodiment Construction

[0036] In order to make those skilled in the technical field of the present application understand the present invention more clearly, the technical solutions of the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0037] Please refer to figure 1 , the distribution system for distributing live code streams in Embodiment 1 of the present application, including:

[0038] The receiving module 101 is configured to receive and store the TS segment files, key files and temporary index files output from the live encoder.

[0039] Specifically, the TS fragment file, key file and index temporary file received by the receiving module 101 are generated by a live encoder, namely:

[0040] The live encoder will combine the multimedia code streams that need to be distributed into one or more TS fragmented files every certain time period, such as 10S, and the multimedia code streams can be audio code streams, v...

Abstract

The present application discloses a method and system for realizing distribution of live code streams, wherein the method for distributing live code streams is used to obtain new files and distribute them to the next-level nodes by analyzing HTTP messages, including the following steps: Receive a first distribution command at the first moment, the first distribution command includes name information of at least one index temporary file; based on the name information of the at least one index temporary file, the first moment and the latest HTTP server At the second moment when the second distribution command is completed, at least one TS segment file and at least one key file are newly added between the first moment and the second moment, wherein each TS segment file uses the A key-encrypted file in at least one key file; and distributing the newly added at least one TS segment file and at least one key file to the lower-level nodes.

Description

technical field [0001] The invention relates to code stream transmission technology in network communication technology, in particular to a method and system for realizing live code stream distribution. Background technique [0002] With the continuous development of Internet technology, computer technology, and communication technology, when users use the network to transfer files, there are more and more ways to transfer files in the network, such as: [0003] The real-time streaming protocol RTSP implemented in the TCP / IP system mentioned in the IETF RFC standard submitted by Columbia University, Netscape and RealNetworks; the HTTP-based live streaming technology proposed by Apple, namely: HLS technology. [0004] However, each method will interact with TS streams. Among them, the RTSP method is to push TS streams interactively between the server and the client, and multi-node distribution; the HLS method uses the HTTP protocol, and the live encoder continuously generates...
