Embodiment Construction

[0016] (1) The live broadcast device opens the live broadcast APP to collect video and audio, and encodes them into video stream data in real time.

[0017] (2) The live broadcast device transmits the video stream data to the data relay device through WIFI (process 1 in the figure). During the transmission process, the video data will be divided into many data packets by the TCP protocol according to the rules (the data packets are transmitted by TCP The smallest unit, the maximum capacity of a packet generally does not exceed 1500 bytes), and transmitted in sequence.

[0018] (3) Assume that the maximum transmission rate of the data relay device is 300Mbps (meaning that the device can receive up to 300M bytes of data per second), which means that it can receive up to about 200K data packets per second, and we assume that the mobile phone is 4G The actual transmission rate of the network varies from 50Mbps to 150Mbps.

[0019] (4) The data relay device forwards the data recei...

Abstract

The invention discloses a method for carrying out outdoor live broadcast by using data relay equipment. The outdoor live broadcast method comprises the following steps that an anchor shoots live broadcast content through a live broadcast APP installed in a mobile phone; the live broadcast APP encodes the shot video signal into video stream data in real time; the video stream data is sent to a datarelay device through WIFI; the data relay device comprises a plurality of network cards, the data relay device and the video stream server completely support the MPTCP protocol, the data relay deviceforwards the video stream data to the video stream server through the MPTCP protocol, and when a user needs to watch live broadcast, the user can directly access the video stream server through the live broadcast APP to play the video. On the premise of not upgrading and reconstructing anchor equipment and user equipment, multi-path transmission of the video stream data is realized, and the problems of unstable network connection and insufficient network bandwidth under the condition of outdoor live broadcast are solved at ultra-low cost.

Description

technical field [0001] The invention relates to the field of network live broadcast, in particular to a method for outdoor stable live broadcast. Background technique [0002] At present, in the outdoor live broadcast system, the connection between the live broadcast equipment and the video streaming server generally uses the traditional TCP protocol as the underlying transmission protocol, and most of the network connection methods are directly connected to the mobile phone 3G or 4G network. However, if the live broadcast If the user is in a high-speed train, or there are tall buildings around, or the mobile phone network signal in the user's area is extremely poor and unstable, the quality of the live broadcast will be greatly reduced. It even loses connection with the server frequently, making it impossible to live broadcast normally at all. The reflections on the viewing users are that the live broadcast screen is blurred, freezes, and often disconnects for no reason. ...
