Optimal processing method for transmitting and receiving real-time video data

Abstract

The invention discloses an optimal processing method for transmitting and receiving real-time video data. When a transmitting end packages the video data, the video data is packaged and transmitted by taking a video frame as a unit; a video data packet is numbered before transmitting, and then organized by taking a window number as a unit; a receiving end judges the receiving completeness of the data according to the number of a receiving frame, and if an unreceived data frame is found, the receiving end transmits a control command to the transmitting end and requests for retransmitting the control command; the receiving end receives the video data transmitted from the transmitting end and then stores the video data into a cache, when the video data in the cache reaches a certain number, video data is decoded and played; and when the video data is decoded and played, the receiving end processes the video data in the cache by taking one window as a group of frames which can be decoded and played completely. The method can reduce the situations of packet loss, lag, unstable speed and the like on a network with insufficient bandwidth or an unstable network so as to improve the display effect of real-time video.

Description

technical field [0001] The invention relates to an optimal processing method for transmitting and receiving real-time video data, in particular to an optimal processing method for transmitting and receiving real-time video data on a network with relatively insufficient or unstable bandwidth. Background technique [0002] Today, with the rapid development of the Internet, the network bandwidth has been greatly developed, and the network applications have become more and more abundant. Real-time video data transmission has gradually developed as a kind of network applications, such as video chat, video conferencing, and video surveillance. field use. However, under certain circumstances, the network bandwidth is still relatively insufficient, for example: network data may cause congestion during peak hours of network use; when using wireless networks to transmit data due to the instability of the network itself or the impact of mobile terminals constantly changing locations T...

Problems solved by technology

However, under certain circumstances, the network bandwidth is still relatively insufficient, for example: network data may cause congestion during peak hours of network use; when using wireless networks to transmit data due to the instability of the network itself or the impact of mobile terminals constantly changing locations The network communication is not smooth; in some places, the network interconnection and intercommunication are not done well enough. When data is transmitted across the operator's network, for example, when the data is transmitted across the network from China Telecom to China Netcom, the actual bandwidth available for data transmission may decrease; all of the above The reason is that the transmission of video data is not always smooth, and there may be packet loss, lag, and unstable rate, which will eventually affect the display effect of real-time video. Therefore, it is necessary to adopt some methods to monitor real-time video The transmission and reception of data is optimized to improve the display effect of real-time video as much as possible
