System-on-chip targets TVs

The PNX8550 from Royal Philips Electronics is a SoC (system-on-a-chip) that has been developed to meet the needs of hybrid digital television designers.

The PNX8550 SoC incorporates a control processor, two programmable media processors, high definition video decoders, a scaler, renderer and numerous other on-chip functions. The SoC will support all analog and digital TV broadcast standards (standard definition and high definition), picture improvement features such as deinterlacing and advanced features such as multiformat audio/video decoding and rendering.

A TV based on the Philips SoC could decode and display digital photographs, MPEG-4 and DV video clips directly from a flash memory card or Memory Stick. Dedicated MPEG-2 decoders can also process up to two high definition program streams simultaneously for simultaneous display on the screen (picture-in-picture or side-by-side) or to convert an HD video program for recording on a standard definition recorder. The SoC also allows manufacturers to add their own proprietary picture and sound improvement features.

The company is also offering a TV reference design based on the new SoC that provides TV manufacturers with the semiconductors and software to make a transition from analog cathode ray tube (CRT) TVs to liquid crystal displays (LCDs) and digital TVs.
