Abstract
Official abstract text for this publication.
For generating a signal to be transmitted original information is encoded into a main channel and a side channel, wherein the side channel is more robust against channel influences than the main channel. On the receiver side, when the receive quality is above a threshold, which is necessitated to execute a successful decoding of the main channel, the main channel is reproduced. If the receive quality falls below this threshold, however, the side channel is reproduced which may have less bits than the main channel and which is a correspondingly lower quality representation of the original information than the main channel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for generating a decoded signal, comprising: a receiver configured to receive a receive signal comprising a main channel and a side channel which are capable of being decoded separate from each other, wherein a minimal signal/noise ratio used to decode the side channel is smaller than a minimal signal/noise ratio used to decode the main channel; a decoder configured to generate a main channel which is separate from the side channel; a qual…
