As analog broadcasts are phased out, the IRP platform (1RU) eases the transition to an all-digital ATSC environment.
In order to meet the requirements of the February 2009 digital TV transition and continue providing must-carry broadcast channels in both digital and analog form, Scopus is demonstrating its Integrated Receiver Processor (IRP) at HD World in New York this week.
The company said cable operators need high-definition receiver solutions that can process, multiplex and perform HD downconversion of off-air ATSC digital broadcasts. The new IRP is a technology platform for advanced receiving and processing applications.
The IRP platform addresses handling of multiformat SD/HD content, H.264/MPEG-2 decoding, transport stream descrambling, IP edge streaming, ASI aggregation, remultiplexing, transmodulation, and HD-to-SD downconversion.
As analog broadcasts are phased out, the IRP platform (1RU) eases the transition to an all-digital ATSC environment. The compact unit serves as a simple solution that cable operators can deploy to decode and downconvert as many as four HD channels, applying dynamic aspect ratio adaptation to the analog NTSC output.
A multiplexing core ensures the IRP’s long-term value to the cable operator, enabling grooming and PSI/SI and PSIP aggregation of multiple HD and SD programs for digital content distribution. The IRP supports a wide variety of inputs (8-VSB, ASI, and IP) and outputs (baseband video, audio, ASI and IP).
