MPEG-4 is a standard for video compression that allows network operators to dramatically improve digital video bandwidth utilization by roughly twice the comparable MPEG-2 industry benchmark for digital video distribution. Telcos, cable operators, and satellite service providers can benefit from the resulting bandwidth efficiencies, and there is a growing trend toward increasing use of MPEG-4 services on digital networks. As digital network operators migrate to MPEG-4 services, there are economic and interoperability issues to address so that service providers can efficiently leverage existing MPEG-2 infrastructure assets while progressively integrating MPEG-4 services deeper into their networks.
