Abstract:
1. A method for communicating video data on a channel in a packet-switched network comprising: performing at a terminal a video encoding operation of said video data and performing a compression operation of the encoded video data in packets; and detecting wireless channel conditions and configuring control parameters of said video encoding operation to said detected wireless channel conditions, wherein said encoded video data compression operation is a robust header compression operation and said configuring control parameters of said video encoding operation is performed as a function of information about said detected wireless channel conditions detected on a feedback channel made available in an encoded video data decompression operation associated with said encoded video data compression operation, wherein said compression operation includes a second mode of operation in which an acknowledge message is generated in the following cases: the first of a sequence of R-0-CRC packets is correctly decompressed; or the first N packets of a sequence of UOR-2, IR or IR-DYN packets are successfully decompressed, wherein the acknowledge message carries a sequence number of the packet that caused its generation.
