Embodiment Construction

[0019] The solutions of the present invention will be described in detail below in the form of specific embodiments.

[0020] figure 1 As shown, it is a schematic flow chart of Embodiment 1 of the method for encoding and decoding cluster transmission of video streams in the present invention.

[0021] The method for the codec cluster transmission video stream includes the following steps:

[0022] Step 101, acquiring the number of decoding devices requesting video streams from a first encoding device among multiple encoding devices within a preset period of time. The preset period, preferably 3 seconds, 5 seconds, 10 seconds or 30 seconds, etc., can be set according to the frequency of video stream requests from the decoding device or some transmission properties of the first encoding device. The first encoding device may be any encoding device in the plurality of encoding devices.

[0023] In this step, preferably, within a preset period of time, according to the decoding ...

Abstract

The invention discloses a method and system for encoding and decoding cluster transmission of video streams. The method includes: obtaining the number of decoding devices requesting video streams from the first encoding device among multiple encoding devices within a preset period of time; requesting the video stream When the number of decoding devices for the stream is higher than the preset value, at least one encoding device is selected from the encoding devices other than the first encoding device among the plurality of encoding devices as the encoding device for sending the video stream; The video stream is sent to a selected encoding device, and the video stream is transmitted to a corresponding decoding device through the selected encoding device. By implementing the method and system of the present invention, the same video stream can be simultaneously transmitted across the wide area network to multiple decoding devices without affecting the coding efficiency of the coding device and the network bandwidth load.

Description

technical field [0001] The present invention relates to the technical field of video coding and decoding clusters, in particular to a method and system for transmitting video streams by a coding and decoding cluster. Background technique [0002] The video codec cluster system includes multiple encoding devices, multiple decoding devices and a network for connecting the encoding devices and the decoding devices. The encoding device is used to collect video data from the front end and compress the video data into a video stream, and transmit the video stream to the decoding device through the network between the two, and the decoding device is used to decompress the video stream and output it to the back end for display. [0003] At present, there are mainly three ways to transmit video streams in the codec cluster system: 1. By establishing TCP (Transmission Control Protocol, Transmission Control Protocol) or UDP (UserDatagram Protocol, User Datagram Protocol) between the de...
