Method and system for communicating video data in a packet-switched network, related network and computer program product therefor

摘要

A method for communicating video data on a wireless channel in a packet-switched network, that includes the steps.of operating at a wireless terminal (100) a compression (10; 204) in packets (106, 108) on the video data during a video coding operation, detecting wireless channel conditions and adapting control parameters of the video coding operation to the detected wireless channel conditions. The compression operation is a robust header compression operation (204) and the step of adapting control parameters of said video coding operation is performed in dependence of information (200, 210, 110) about the wireless channel conditions detected on a feedback channel made available in a decompression step (202) associated to the compression operation (204). Preferred application in mobile phones and video over IP applications.
