Abstract:
The PIP system enables display of a mosaic of favorite channels in a Picture-in-Picture (PIP) format to a subscriber terminal. Picture-in-Picture support is efficiently provided by sending only I-Frames of the secondary video channel to the end-user. That is, any unnecessary packets (null, B-P frames, audio, etc.) in the secondary video channel are stripped away. This method uses very little bandwidth and is STB agnostic.
