Abstract
The application discloses an omnidirectional channel prediction and dynamic coding joint decision method, system and medium, belonging to the multimedia field, and the method is applied to an FTTR gateway and comprises the following steps: determining the communication connection type of the FTTR gateway, a screened terminal and a terminal to be screened according to the IP addresses of the terminal to be screened and the terminal to be screened; determining a first available bandwidth of a video stream flowing from the FTTR gateway to the terminal to be screened and a second available bandwidth of the video stream flowing from the terminal to be screened to the FTTR gateway; determining the smaller value in the first available bandwidth and the second available bandwidth as a maximum code rate B_max available for the screen projection, and notifying the terminal to be screened of the B_max to trigger the terminal to be screened to determine target video coding parameters. The method can provide highly stable bandwidth guarantee for the screen projection service.
