Harris Corporation To Introduce IP-Controlled Statistical Multiplexing For High-Density Encoding At NAB2008

H.264 Statistical Multiplexing Extends Harris Range Of Multiplatform Delivery Solutions For Networking (February 21, 2008)
DMN Newswire--2008-2-21--Harris Corporation (NYSE: HRS), an international communications and information technology company, will extend its range of multiplatform delivery solutions with the introduction of a new statistical multiplexing (StatMux) feature to its NetVX MPEG-4/H.264 video encoders at the 2008 National Association of Broadcasters (NAB) convention taking place April 14-17 in Las Vegas (Booth N2502, Las Vegas Convention Center).

The Harris® NetVX distributed StatMux feature is designed to take advantage of the compression efficiencies delivered by the ENC-A21 MPEG-4/H.264 video encoder. This new feature provides efficient statistical multiplexing of MPEG4/H.264 video, either within a single NetVX chassis or distributed across multiple frames. A direct-to-home service provider can now multiplex eight or more HD channels using MPEG-4/H.264 compared to half that number using older MPEG-2 compression in a single transponder, resulting in significant cost savings to the service provider.

?Consumer demand for HD content continues to rise, said Tim Thorsteinson, president of Harris Broadcast Communications. ?Service providers are looking for ways to deliver more HD channels without having to make significant investments in additional transmission bandwidth. Using our NetVX encoders and built-in statistical multiplexing features, broadcasters and service providers can deliver HD content more efficiently to their customers.


The Harris® H.264 StatMux feature uses Internet Protocol (IP) communications to determine which encoders around the facility have ?bits to spare. Then, bandwidth demands can be balanced to deliver a single transport stream with multiple SD and HD channels. This control protocol is integrated within the high-availability architecture of the NetVX system, providing reliable operation without dependency on external control systems.

The H.264 StatMux feature will be available in late March. Visitors to Harris Corporations NAB2008 booth can see a live demonstration of the new feature operating with NetVX ENC-A21 MPEG-4/H.264 video encoders. The NAB demo will show eight channels, multiplexed into a single transponder.  This capability allows the service provider to deliver more channels to customers, in particular HD services, with no additional satellite costs.

NetVX encoders, multiplexers and statistical multiplexers are among the wide range of Harris solutions that optimize the media transport workflows of todays broadcast operations.

Harris Broadcast Communications provides products, systems and services that deliver interoperable workflow solutions that span the entire broadcast delivery chain. The Harris ONE approach brings together highly integrated and cost-effective products that are ideal for emerging media business models and for customers upgrading media operations to digital and high-definition services.
