Patent ID: 8576816

Claim:
A method for transmitting data in a transmission system, the data being transmitted in the form of packets comprising at least one compressed header field and one data payload field and according to a format suited to the transmission system comprising the following steps: recovering the data packet to be transmitted which comprises a compressed header field and a payload field, identifying the header part from the payload field; applying a selected forward error corrector (FEC) coding to the compressed header field of the data packet, and providing to a link layer a resulting new packet comprising the FEC coded compressed header and the uncoded payload, while also communicating a protection mode of the selected FEC coding; generating the link layer header according to the transmission format of the transmission system integrating said protection mode, and an adaptation of a CRC checksum of the link layer; and on reception, performing error corrector decoding in two steps, based on the protection mode integrated in the link layer header, said two steps including: a first step of decoding a first part of the FEC coded compressed header, making it possible to deduce information regarding a size of the compressed header, a second step of decoding a remainder of the FEC coded compressed header on the basis of the previously determined size information.
