High-Def Interface Streamlines HDTV Video Processor

A high-definition multimedia interface (HDMI) has finally been integrated into a video processor, namely the Sil 8100. Developed by Silicon Image, the processor targets mainstream direct-view digital televisions (DTVs) like low-cost LCD and CRT-based TVs. This fully integrated system incorporates HDMI with high-bandwidth digital content protection (HDCP) and a high-definition (HD) component video input, as well as advanced image and video processing.

Included on-chip are the company's HDMI receiver and an RGB/YPbPr video analog-to-digital converter for full compatibility with existing HD analog products. The Sil 8100 performs high-quality video scaling and 3D motion-adaptive video deinterlacing. With its integrated standard-definition (SD) ITU-R BT.656 video input port, the chip can handle digitized SD signals from a video decoder or audio/video switch for connection to SD systems like VCRs and game consoles.

Additionally, the Sil 8100 can support 50- to 60-Hz video rate conversion. It packs advanced image processing to eliminate many common image artifacts and provide common color controls for hue, saturation, brightness, and contrast. An integrated microcontroller eliminates the need for a costly external microprocessor. And, an 8-bit on-screen display (OSD) processor supports on-screen graphics overlays.

Programmable subpicture location and size are possible thanks to the chip's picture-in-picture processor. It also overlays one video input over another input or graphics frame to create a single input. Multiple outputs—including TTL, digital-to-analog converter, and low-voltage differential signaling—support projection engines, CRTs, LCDs, plasma display panels, and other common display devices.

A complete set of hardware and software development tools lets system manufacturers easily incorporate the SiI 8100 into their designs. Moreover, its complete functional design makes it possible to connect directly to an LCD panel or other display.

Housed in a 256-pin LQFP, the Sil 8100 costs $13.95 apiece in 10,000-unit lots. It will sample in April, with volume production scheduled for June.
