Abstract

Competitive HDTV offerings compel Cable Operators to make plans for 100+ HD Broadcast channels and 10% HD-VOD service (peak capacity), as well as devise innovative on-demand and Time Shifted television services. Unfortunately, the current networks are unable to carry the load. The various bandwidth enhancement options are capital intensive, disruptive to existing infrastructure and, for the most part, don’t provide sufficient bandwidth. This study analyzes SDV Unicast and Edge Statistical Multiplexing (StatMux), concluding that it is the most cost-effective and least disruptive method for handling the HDTV bandwidth explosion.
