Problems solved by technology

This implementation method is more suitable for private networks with good and controllable bandwidth, but not very suitable for the Internet with complex network conditions. Moreover, due to the complexity of the protocol, the deployment of streaming media services is not flexible and the scalability is poor.
In addition, since the webcast based on the streaming media protocol usually requires the client to support the same protocol, the client can watch the live video, so there are considerable limitations in the communication between the server and the client.
In recent years, as streaming media services occupy a large amount of operator bandwidth, it often happens that operators block and interfere with streaming media services, which directly causes the loss of audio and video signal packets during network transmission, making users watch live video. Phenomena such as picture mosaic and output picture discontinuity often appear in

Embodiment

[0019] figure 1 It is a flow chart of the client initiating the video live broadcast request and the server sending the request in the present invention.

[0020] Such as figure 1 shown, including the following steps:

[0021] The live broadcast server first receives the video stream and audio stream collected by the encoding device, cuts and encapsulates the received video and audio stream into files of various formats and multiple time periods.

[0022] Wherein, the live broadcast server uniformly sets the time unit for each video stream to be cut and segmented, and the time unit is the time length unit of each small file after a video film is segmented. After the setting is completed, the live broadcast server performs real-time slice processing on each video stream according to the set time period, and dynamically generates a playlist arranged in time order at the same time.

[0023] For example, if the live broadcast server is set to generate a small file of a specifie...

Abstract

The invention discloses a method and system for video live broadcasting in a small file slice mode based on a hypertext transport protocol (HTTP). The method is characterized in that an HTTP mode is adopted to communicate with a client-side; and a server-side splices each video stream into a plurality of small files of different formats in real time in accordance with specified time segments and then sends the obtained small files to the client-side. When network bandwidth is restricted, if the small files of the videos are lost, the server-side retransmits the small files to the client-side, thus ensuring the continuity when a user watches the videos, and improving the user experience.

Description

technical field [0001] The invention relates to mobile communication and Internet communication technology, in particular to a method and system for live video broadcasting in a small file slicing mode based on the HTTP protocol. Background technique [0002] High-definition and smooth online video live broadcast has become the highlight and advantage of today's online video. With the increasing popularity of home computers and the continuous increase of online high-definition video and content, people have an urgent and realistic demand for watching high-definition online video live broadcast. [0003] Most of the current network live broadcast technologies are based on relatively complex streaming media protocols, therefore, the server needs the support of the streaming media server. This implementation method is more suitable for private networks with good and controllable bandwidth, but not very suitable for the Internet with complex network conditions. Moreover, due to...
