ROBUST MODE STAGGERCASTING VIDEO QUALITY ENHANCEMENT.

摘要

A method and apparatus for staggercasting a content representative signal (figs. 1-2), having a first portion and a second portion includes the following. A first signal is encoded (120) representing the first portion of the content representative signal and a second signal is encoded (110) representing the second portion of the content representative signal. A composite signal (115 or 205) is generated comprising the first and second encoded signals, staggered in time. The first and second encoded signals are extracted from the composite signal (exit of 210) and errors (E) detected in the first and second extracted encoded signals. If an error is detected in one of the first and second extracted encoded signals, then the other one of the first and second extracted encoded signals is decoded to reproduce the corresponding portion of the content representative signal (215). Otherwise both the first and second extracted encoded signals are decoded and combined to reproduce the content representative signal.
