GI Offers First-Hand Demonstrations of How the New Features Enable Operators To Easily Mix SD and HD Services in a Single, ATSC-Compliant Multiplex, at the
1999 NAB Convention
SAN DIEGO, April 16 /PRNewswire/ -- General Instrument Corporation (NYSE: GIC) announced today that it is unveiling a new version of its DigiCipher(R) II encoding system that enables operators to easily mix SD and HD services in a single, ATSC-compliant multiplex. GI is demonstrating this new system in use at its Booth L24068 (Las Vegas Convention Center) throughout the National Association of Broadcasters (NAB) Convention.
GI is demonstrating how, using this new DigiCipher II version, operators can offer multiple SD services during one portion of the day and rapidly switch off the SD service to turn on an HD service (in primetime, for example). The DigiCipher II system architecture supports this feature by processing all of the SD signals in a single, multi-channel enclosure while it processes the HD signal in a separate HD enclosure. The two enclosures are connected through an internal multiplexer that can store the parameters of all (SD and HD) channels in addition to the programmed switch time. Packets of the various streams are aligned to ensure a smooth switch during the service transition.
The new version supports the combination of SD and HD signals in the same multiplex. This means that broadcasters can fulfill the demand for HD services while offering a value-added SD service at the same time.
"GI is very pleased to introduce the latest version of the DigiCipher II encoder system at NAB, and we look forward to demonstrating how easily operators can use it to mix SD and HD services in a single multiplex," said Thomas J. Lynch, Senior Vice President and General Manager of GI's Satellite and Broadcast Network Systems business unit. "The DigiCipher II advanced compression technology allows operators to combine HD and SD signals without visibly affecting the video quality of either service."
DigiCipher II technology is developed by General Instrument's San Diego- based Satellite and Broadcast Network Systems business unit, which provides digital television systems sending compressed video service to cable television headends, television network affiliates, corporate locations, or consumer homes. The technology compresses and multiplexes both SDTV and HDTV signals within a single integrated transmission system. It is compatible with MPEG -2 standards for transport and video syntax. The DigiCipher II system uses the Dolby(R) AC-3 audio compression system.
General Instrument Corporation (NYSE: GIC) is a leading provider of integrated and interactive broadband access solutions, teaming with its business partners to lead convergence of the Internet, telecommunications, and video entertainment industries.
