Abstract
The invention provides signal coding, wherein the signal is source coded to obtain a coded data stream, and source significance information (SSI) is included into the coded data stream, the source significance information (SSI) indicating desired protection rates of respective parts of the coded data stream. In this way, a channel encoder may obtain the source significance information (SSI) from the coded data stream, which is advantageous in presence of intermediate network layers. Preferably, the coded data stream comprises respective packets, the being included in respective headers associated with the respective packets, a given header indicating desired protection rates for respective parts (p) of the associated packet. In order to provide easy detection of the source significance information (SSI), a first header (SSI) is placed at a beginning of the coded data stream. Alternatively, the header (SSI) is provided with an identifier.
