Patent ID: 8380522

Claim:
A compression device for compressing data contained in input frames to be compressed constituted of stream frames defining portions of transmission rate adaptation unit (TRAU) and signaling frames that have to be transmitted within a communication network and each of which comprising at least a header containing control data representative at least of one of a type of the stream frame and payload data, certain types containing at least one of critical and non-critical data, the compression device comprising: analysis module which analyzes each TRAU or signaling frame header contained in successively received input frames and determines the type of a respective input frame; and compression module which generates periodically compressed frames, wherein each frame is divided into a first section of a first size, which corresponds to a critical data size, and a second section of a second size, different from the first size, said critical data is compressed synchronously into the first section, said non-critical data is compressed asynchronously into the second section after the critical data of the critical data size is compressed into the first section, and the compressed frame having the first section and second section is transmitted within the communication network.
