Abstract
Abstract A transmission system comprising a transmitter comprising at least a first channel encoder for encoding source symbols into coded symbols and for setting at least one coding property thereof, and a further channel encoder for encoding the at least one coding property of the at least first channel encoder; and a reciever comprising at least a first channel decoder for deriving reconstructed source symbols from the coded symbols received from the transmitter and a further channel decoder for obtaining the at least one coding property by decoding the encoded coding property; wherein the receiver is capable of setting the at least one coding property of the at least first channel decoder according to the at least one coding property and the transmitter is capable of transmitting the encoded coding property to the receive over a transmission channel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A receiver which is arranged to receive at least one encoded coding property set at a transmitter and coded symbols which have been encoded at the transmitter in accordance with the at least one coding property, said receiver comprising at least a first decoder for deriving reconstructed source symbols from the received coded symbols, and a further decoder for obtaining the at least one coding property by decoding the encoded coding property, said receiver being further arranged for setting the at least one coding property of the at least first decoder according to the at least one coding property.
Claim 2
Dependent Claim
99 words
A receiver which is arranged to receive at least one encoded coding property set at a transmitter and coded symbols which have been encoded at the transmitter in accordance with the at least one coding property, said receiver comprising at least a first decoder for deriving reconstructed source symbols from the received coded symbols, and a further decoder for obtaining the at least one coding property by decoding the encoded coding property, said receiver being further arranged for setting the at least one coding property of the at least first decoder according to the at least one coding property.
Claim 3
Dependent Claim
26 words
The receiver as claimed in claim 1 , wherein the receiver is arranged to receive the encoded coding property and the coded symbols via separate channels.
Claim 4
Dependent Claim
72 words
A transmitter comprising at least a first encoder for encoding source symbols into coded symbols in accordance with at least one coding property, coding property setting means for setting the at least one coding property of the at least first encoder, a further encoder for encoding the at least one coding property of the at least first encoder, said transmitter being arranged for transmitting the coded symbols and the encoded coding property.
Claim 5
Dependent Claim
72 words
A transmitter comprising at least a first encoder for encoding source symbols into coded symbols in accordance with at least one coding property, coding property setting means for setting the at least one coding property of the at least first encoder, a further encoder for encoding the at least one coding property of the at least first encoder, said transmitter being arranged for transmitting the coded symbols and the encoded coding property.
Claim 6
Dependent Claim
26 words
The transmitter as claimed in claim 3 , wherein the transmitter is arranged to transmit the encoded coding property and the coded symbols via separate channels.
