Abstract
Various implementations provide one or more of improved programming channel change time and/or overall quality of television reception by using multiple transmission channels. In one particular implementation, a first layer of a picture is encoded using a first level of error protection. The encoded first layer has a first decoding delay. A second layer of the picture is encoded using a second level of error protection. The encoded second layer has a second decoding delay. The second level of error protection is lower than the first level of error protection, and the second decoding delay is longer than the first decoding delay. Other implementations provide a signal or signal structure carrying the encoded first and second layers. Yet further implementations decode the encoded first and second layers.
