Horizon And Scorpus Collaborate On Digital-Video Decoder/Processor

Scopus Video Networks will use Horizon Semiconductor's high definition decoding technology in its receiver processor for multi-channel ATSC decoding/down conversion. Horizon designs semiconductor devices used for secure video/audio compression and transmission in the consumer electronics and broadcast markets. Scopus Video Networks provides digital video networking systems. The two companies have worked to integrate Horizon's Hz4210 SoC into Scopus' integrated receiver processor (IRP-3910), a multi-channel professional decoder/processor/down-converter unit.

The IRP-3910 is specifically designed to enable cable operators' transition from analog to ATSC digital television broadcasting. It's packaged in a 1-RU chassis, and provides up to four channels of HD decoding along with dynamic aspect ratio conversion. It also incorporates a multiplexing core that performs grooming and PSIP aggregation of multiple HD and SD programs for digital content distribution.

Horizon's Hz4210 high-definition, single-channel MPEG-2/AVC/VC1 audio/video decoder SoC de-multiplexes incoming off-air ATSC transport streams and extracts VBI data, timestamps, aspect ratio, and other related stream parameters. It also filters and decodes certain user programmable channels, down-mixes 5.1 Dolby AC-3 audio into stereo audio, and performs professional HD down conversion scaling and automatic aspect ratio correction. The output signal is then post-processed for enhanced video quality.

The IRP-3910 will be demonstrated at SCTE Cable-Tec Expo 2008 taking place this week in Philadelphia.
