Delivering video across a variety of platforms involving multiple codecs can be efficiently handled by multicore media processors. Part One is an overview of the challenge and the codecs involved (including the rarely-mentioned MPEG-3!)
The cable-TV industry needs to move to targeted advertising, but cost challenges such as HD ad splicing and additional infrastructure requirements make it slow going. Here’s a gradual approach that cable-TV MSOs can begin deploying without the need for new set top boxes.
