Embodiment 1

[0060] Such as figure 1 As shown, the P2P live broadcast delay control system of this embodiment includes a data writing module 1 , an analysis module 2 and a filling module 3 .

[0061] Wherein, the data writing module 1 is used to write the multimedia data into the chunk after the live broadcast source station receives the multimedia data to be broadcast live;

[0062] In this embodiment, the multimedia data here is video data;

[0063] The analysis module 2 will detect whether the chunk is full after the preset delay time, and when the detection is no, call the filling module 3;

[0064] The filling module 3 uses the chunk filling technology to fill up the chunks. Wherein, the chunk filling technique of the present invention may include related data writing techniques applicable to writing data into chunks in the art.

[0065] In the process of P2P live broadcast, the life cycle of a chunk is as follows:

[0066] t0: The first video data byte of the chunk is generated a...

Embodiment 2

[0085] Such as image 3 As shown, the delay control system of the P2P live broadcast of this embodiment is basically the same as that of Embodiment 1, the difference is that: the delay control system of the P2P live broadcast of this embodiment also includes a live broadcast source 5 and a distribution module 6;

[0086] Wherein, the live broadcast source 5 is used to collect video data to be broadcast live, which can be collected by means of photography, etc., and the collected video data to be broadcast live is transmitted to the live broadcast source station through a multimedia transmission protocol, specifically The transmission can be carried out through RTMP (Real-time Message Transmission Protocol). Of course, the multimedia transmission protocol in the present invention is not limited to the above-mentioned RTMP, and may also include other multimedia transmission protocols.

[0087] The distribution module 6 then distributes the full chunks to each live broadcast node...

Embodiment 3

[0090] The delay control method of the P2P live broadcast of this embodiment is realized by the delay control system of the P2P live broadcast of the embodiment 1, such as Figure 4 As shown, the delay control method of the P2P live broadcast includes the following steps:

[0091] Step 101, after receiving the video data to be broadcasted at the source station of the live broadcast, write the video data into the chunk;

[0092] Step 102. Detect whether the chunk is full after the preset delay time, and when the detection is no, execute step 103;

[0093] Step 103, using chunk filling technology to fill up the chunk.

[0094] Wherein, in step 101, the capacity of the chunk will be preset by the server, and the server will notify each live node of the capacity of the chunk, and in step 102, it will be detected whether the video data written in the chunk after the preset delay time Reach the capacity to detect whether the chunk is full.

[0095] Specifically, in step 101, the ...

Abstract

The invention discloses a P2P live broadcasting delay control system and a P2P live broadcasting delay control method. The P2P live broadcasting delay control system comprises a data writing module used for writing multimedia data into a chunk after the multimedia data to be lively broadcasted is received by a live broadcasting source station, an analysis module used for detecting whether the chunk is fully filled after a preset delay time, and calling a filling module when a detection result is no; and the filling module used for filling the chunk by using a chunk filling technology. According to the system and the method provided by the invention, whether the chunk is fully filled can be detected in time, and the chunk can be instantly filled by using the chunk filling technology when the chunk is not fully filled during a processing of writing the multi-media data into the chunk, so that the problem that the chunk cannot be filled rapidly due to an excessive low data transmission speed is solved, the delay appearing when the chunk is filling is controlled, and thus the delay time in P2P live broadcasting is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of network streaming media, in particular to a P2P live broadcast delay control system and method. Background technique [0002] With the development of the Internet, it has become a hotspot to use the network for streaming media playback. Streaming media refers to multimedia that uses streaming technology on the Internet (Internet) / Intranet (Intranet). Streaming media does not need to download the entire file before playing, and can be watched while downloading. The principle is to divide the multimedia files transmitted to the user into different segments according to the order of broadcasting time, and then send these segments to the user in turn, and play these segments continuously to form continuous sound and images. [0003] P2P (Peer to Peer, peer-to-peer network) live broadcast is a new network live broadcast technology in recent years. Compared with the traditional network live broadcast mode, a v...
