Problems solved by technology

[0003] The TCP protocol adopts a connection-oriented method. When a frame of video data is lost, it will be retransmitted. Since the data volume of a video frame is relatively large, when the network is congested, retransmission will increase the network burden, resulting in retransmission failure. The probability increases, resulting in the loss of video frame data
[0004] The UDP protocol adopts a connectionless method. When the video data encounters network congestion or interference during the transmission process, causing the signal to be lost or unable to be parsed, the video data will be lost and the playback screen will freeze due to the absence of a retransmission mechanism.

Abstract

The invention provides a video data transmission method and device and electronic equipment, and the method comprises the steps: splitting any frame of video data to be transmitted into a plurality of data split packets; adding packet header information to each data split packet in the plurality of data split packets, and sending the data split packets added with the packet header information to a receiving end device; before the transmission time of the frame of video data reaches a single-frame video data transmission time threshold value, if it is determined that data split packets are lost in the multiple data split packets, retransmitting the lost data split packets; if it is determined that the plurality of data split packets are all successfully sent, ending the sending of the frame of video data; when the transmission time of the frame of video data reaches a single-frame video data transmission time threshold, ending the transmission of the frame of video data. According to the method, the data transmission efficiency can be improved, and low-delay transmission of the video data is realized.

Description

technical field [0001] The present application relates to the technical field of electronic communication, in particular to a video data transmission method, device and electronic equipment. Background technique [0002] Traditional video transmission is mostly implemented based on User Datagram Protocol (User Datagram Protocol, UDP) and Transmission Control Protocol (Transmission Control Protocol, referred to as TCP). [0003] The TCP protocol adopts a connection-oriented method. When a frame of video data is lost, it will be retransmitted. Since the data volume of a video frame is relatively large, when the network is congested, retransmission will increase the network burden, resulting in retransmission failure. The probability increases, resulting in loss of video frame data. [0004] The UDP protocol adopts a connectionless method. When the video data encounters network congestion or interference during the transmission process, causing the signal to be lost or unable ...
