Method and system for transmission of a digital signal coded with N bits by an emitting and receiving interface for signal coded with N+M bits and utilisation in digital television.

摘要

The invention relates to a method for transmitting a digital signal coded with N bits by an N+M bit interface. On transmission, each coded word (MCk) is associated with a qualification word (MQk) coded with at most M bits, by a coding law specified by correlation with the value of the coded word, in order to constitute a qualified word which is transmitted thus enabling an improvement in the reliability of transmission to be afforded on reception. Application to the transmission of digital television signals. <IMAGE>
