Abstract:
1. A method, comprising: receiving a single video stream, wherein the video stream includes plural processed representations of a single video signal, wherein each of the plural processed representations of the video signal (PPROTVS) includes a respective sequence of compressed latticed pictures, wherein each compressed latticed picture of each of the PPROTVS represents a corresponding respective picture of the video signal, wherein each respective picture of the video signal is represented by at most one compressed latticed picture from each of the PPROTVS, wherein corresponding segments of the PPROTVS are ordered and time shifted relative to each other to facilitate error concealment, the time-shift imposed by interspersing of non-corresponding segments between each of the corresponding segments; and providing error concealment on the received video stream, wherein the receiving includes receiving within each of first successive plural, non-overlapping segments distribution intervals (SDIs) no more than one segment of a first complete set of the corresponding segments and the one or more of non-corresponding segments, the receiving of the first complete set occurring over a minimum set of successive continuous SDIs, wherein responsive to an error within a first segment in the SDI, repeatedly displaying a decompressed version of a first compressed latticed picture of an oldest segment beginning approximately from a respective location within the segment where the error occurred and ending at a location corresponding to the last picture just prior to where the error occurred, and further comprising repeatedly displaying a decompressed version of the last compressed latticed picture until decoding of a next successive SDI is commenced, the oldest segment corresponding to the respective compressed latticed pictures of the segment in each SDI having the earlier picture output span.
