STMicroelectronics introduced a dual-channel DTV solution called DTV100. This production-ready reference design is based on the company's STD2000 single-chip HDTV processor, which is manufactured in 90nm CMOS technology.

The STD2000 processor can decode and display both analog and digital broadcasts, while eliminating multi-path interference and adjacent-channel noise. This device can decode two simultaneous standard-definition signals, as well as provide high-definition (HD) decompression, video processing, and display for CRT or flat-panel TVs.

ST's patent-pending contour-sensitive de-interlacing uses advanced algorithms, such as pixel-based video analysis, adaptive pixel interpolation and field merging, to eliminate the negative effects of interlaced coding. Another tool for image quality improvement featured in the STD2000 is the 3D digital luma and chroma motion-adaptive noise reduction.

The HD picture-and-picture and picture-in-picture features enable TVs manufactured with the STD2000 to display two separate HD video sources on one screen, side-by-side and on top of each other, respectively.

The audio is delivered by the STV82x7/8 family of processors. From enhanced stereo to the 5.1-channel surround sound, the STV82x7/8 DSPs offer standard features as well as sound enhancements.

The redundancy between analog and digital video processing has been removed, and, while most digital TV sets today use a two-or-more-chip solution, said ST, its DTV100 platform integrates the MPEG-2 A/V, the HD video processor and all support for legacy analog broadcast into a single chip.

"Our integrated DTV100 platform is delivered as a production-ready reference design, with software development tools and ready-to-use modules for advanced TV applications," said Luigi Mantellassi, director of ST's DTV business unit. "The advanced platform can be quickly tailored to a finished product that facilitates product differentiation with minimal additional efforts and cost."

The STD2000's production is planned for Q2 2006.
