Abstract
Headers of image frames are compressed. Header of a first frame is received, where the header includes a plurality of header parameters. Further, differences are determined between the header parameters and a plurality of default parameters, and non-default parameters are sent when there are differences. The header is then compressed to include only a first type of marker, and is sent through the transmission channel. In one embodiment, the non-default parameters are sent through a control channel, while the compressed header is sent through a data channel.
