Abstract

A wireless audio-video transmission system and method, the system includes: a transmitting device, used to generate an image packet according to an image data and a transmission setting information; a receiving device, used to receive the above-mentioned image packet; a detection device, used A first image processing capability of the receiving device is detected, and the transmission setting information is output according to the detected first image processing capability. The invention can reduce the dependence on the bandwidth requirement, and can transfer part of the image generation task to the receiving end for processing, thereby reducing the dependence on the transmitting end system.

Description

technical field [0001] The invention relates to wireless audio-video transmission technology, in particular to the technology of using the image processing ability of the receiving end to execute the image compensation mechanism. Background technique [0002] With the improvement and popularization of wireless technology, more and more user behaviors are moving towards wireless operation, from the early wireless keyboard and mouse, to wireless Internet access, and wireless audio and video transmission, which has received more and more attention recently. , are achieved using wireless technology. However, today's wireless audio-video transmission often encounters several problems when it is applied, such as 1. The size of the transmission bandwidth; 2. The popularity of wireless transmission hardware; 3. The hardware capability of the transmitting end is insufficient. Solutions with better bandwidth often require more special technology and hardware. Although the popular wir...
