Abstract
A video processing method is implemented by transmitting and receiving devices, and includes: obtaining a standard resolution source image frame from an image sequence, and detecting a network bandwidth; when an encoding bit rate of the source image frame exceeds the network bandwidth, decreasing a resolution thereof to obtain reduced image frame content and generating a relay image frame containing the same and having an encoding bit rate not exceeding the network bandwidth; generating an encoded image frame by encoding the source or the relay image frame, and sending the encoded image frame to the receiving device; and decoding the encoded image frame to obtain the source or the relay image frame, and recovering from the relay image frame, when obtained, a restored image frame corresponding to the reduced image frame content and having the standard resolution. A video processing system is also disclosed.
