Abstract
In one embodiment, a method that includes 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.
