IP for TV

New silicon IP from Sarnoff makes it easier for TV makers to meet the US FCC requirement that half of all TV sets 36 inches or larger sold after July 1 include digital TV capabilities.

New silicon intellectual property (IP) now available for licensing from Sarnoff Corporation makes it easier for TV makers to meet the US FCC requirement that half of all TV sets 36 inches or larger sold after July 1 include digital TV capabilities.

The Sarnoff silicon IP is a complete, integrated audio and video system processor for digital TV, including high definition television (HDTV), ready for incorporation into a television or set-top box design. It will decode and display all standard ATSC digital TV signals at any resolution that the television set can accommodate, up to and including HDTV.

The system also includes full Dolby Digital (AC-3) capabilities for receiving and playing 5.1-channel surround sound.

The digital decoding and display system is capable of decoding all 36 input formats specified by the ATSC standard. Any input format can be displayed at HDTV resolution (1080i and 720p) or at standard resolution (480p and 480i).

“By July 1, 2007 sets as small as 13 inches will be affected by this mandate. It’s unlikely makers will put HD displays in sets this small, so the ability to display HDTV at standard resolutions is crucial,” said said Bill Mayweather, Sarnoff Silicon Strategies Business Director.

The display processor is also capable of scaling pictures for zoom in or zoom out effects.

The system includes a transport parser, a 24-bit audio decoder, a 32-bit DDR SDRAM controller, a display processor, an on-screen display, a de-interlacer, and a digital video encoder.

The 24-bit DSP audio decoder subsystem is used to decode the Dolby Digital (AC-3) 5.1-channel surround sound often broadcast as part of a digital TV signal.

Sarnoff’s digital TV IP is available for immediately. The ‘deliverables’ include Verilog source code and test benches, firmware, documentation and engineering support. The IP can be customised to add additional features for specific applications.
