Cable companies are preparing for the analog shutdown by replacing analog off-air receivers with professional ATSC receivers, and Scopus Video Networks has introduced a new integrated receiver processor, the IRP-3910, for cable applications.

The IRP-3910 can provide up to four channels of HD decoding. It supports AFD dynamic aspect ratio conversion and can input 8-VSB, ASI, and IP signals. Output formats include base band video and audio, ASI and IP. The IRP-3910 includes a built in multiplexer that enables grooming and PSIP aggregation of multiple HD and SD channels, eliminating the need for an external multiplexer.

“Scopus’ IRP-3910 is an elegant and effective solution that meets transition challenge,” said Yan Mostovoy, product marketing management and vice president at Scopus. “Now, any off-air HDTV digital TV service can be downconverted for analog SD delivery by the IRP-3910.”

See the Scopus news release for more information the unit and the Horizon Semiconductors news release for details on the Hz4210 system on a chip (SoC) that’s the heart of the unit.
