    摘要： A method and apparatus for staggercasting includes encoding a set of signals representing content such that each encoded signal, alone or in combination with other encoded signals, is capable of being decoded to produce a corresponding decoded signal. Each decoded signal has a reproduced quality which different from the reproduced quality of all the other decoded signals. A composite signal is generated including the set of encoded signals. The encoded signal corresponding to a lowest quality decoded signal is undelayed. The other encoded signals are delayed by different amounts such that the higher the quality of the corresponding decoded signal, the longer the delay period. The set of encoded signals is extracted from the composite signal, and errors in the set of extracted encoded signals detected. A subset of available extracted encoded signals which are not erroneous is produced. A content representative signal at the highest quality possible is decoded from the subset of available extracted encoded signals.

    摘要： A method and apparatus for staggercasting a plurality of content representative signals includes encoding a first and a corresponding second signal representing each of the plurality of content representative signals. A composite signal is generated comprising the plurality of first and second encoded signals. In the composite signal, each respective second encoded signal is delayed with respect to the corresponding first encoded signal. The first and second encoded signal representing a selected one of the content representative signals is extracted to reproduce the selected content representative signal. The extracted first encoded signal is decoded if an error is detected in the extracted second encoded signal, otherwise the extracted second encoded signal is decoded. When a different content representative signal is newly selected, the first extracted encoded signal is decoded until the delayed second extracted encoded signal is available.

    摘要： A decoding arrangement for decoding pictures in an incoming video stream includes a noise generator for adding a dither signal containing random noise to the pictures after video decoding, to improve the subjective video quality. The noise generator adds noise to each pixel in an amount correlated to additive noise of pixels in a prior picture, either a previously displayed picture (i.e., a previously decoded picture to which noise has been added), or a previously decoded picture.
