MANHASSET, N.Y. " Sarnoff Corp. has introduced silicon IP aimed at helping TV makers meet a federal requirement that half of all TV sets 36 inches or larger and sold after July 1 must include digital TV capabilities.
Sarnoff's silicon IP is an integrated audio and video system processor designed to decode and display standard digital TV signals at any resolution that the television set can accommodate, up to and including HDTV.
The digital decoding and display system can decode all 36 input formats specified by the Advanced Television Systems Committee (ATSC) standard. Any input format can be displayed at HDTV resolution (1080i and 720p) or at standard resolution (480p and 480i).
"Eventually this system will [also] go into 13-inch TVs," said Mike Patti, technical director of the Integrated Circuit Systems Group for Sarnoff (Princeton, N.J.). Patti added that the Federal Communications Commission will require TV sets as small as 13 inches to receive digital signals by July 1, 2007, even if they don't have high-definition displays.
"When you look at a digital picture, the difference is obvious compared to an analog TV," Patti said. He expects the IP solution to generate interest not only from makers of new TVs but also low-cost set-top converter boxes as consumers seek to extend the life of older TV sets.
The display processor can also scale pictures for zoom-in or -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 deinterlacer and a digital video encoder. The 24-bit audio decoder subsystem is a DSP solution 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 immediate delivery. The deliverables include Verilog source code and test benches, firmware, extensive documentation and engineering support. The IP can be customized to add additional features for specific applications.
