Abstract

The invention provides a method for adjusting a video code stream and a video frame loss processing method. The method for adjusting the video code stream is applied to a wireless image transmission system, and comprises the following steps: acquiring a specified transmission index of a current network, the specified transmission index comprising a transmission rate and identification informationrepresenting the change trend of the transmission rate; and determining whether to adjust the current code stream parameter of video coding or not according to the specified transmission index. According to the method, the code stream parameter of video coding can adapt to the change of the transmission rate of the wireless network, and when the transmission rate of the wireless network is reduced, the data volume needing to be transmitted per second of the video can be reduced by reducing the code stream parameter, so that the real-time performance of video data transmission is ensured.

Description

technical field [0001] The present application relates to the technical field of video transmission, in particular to a method for adjusting a video code stream and a method for processing video frame loss. Background technique [0002] The wireless image transmission system usually includes a transmitter and a receiver, and the connection between the transmitter and the receiver is established through a wireless network. When the system is working, the shooting device transmits the captured video data to the transmitter, the transmitter transmits the video data to the receiver through the wireless network, and the receiver outputs the video data to the display device to realize remote wireless transmission of video data. [0003] However, the environment of the wireless network is changing dynamically. When the wireless network environment is poor, the transmission of video data will be delayed, and the playback of the video cannot be kept in real time. Contents of the in...
