SUNNYVALE, CALIF. Philips Semiconductors has introduced its SAA7108 PC-Codec, a single-chip video encoder and decoder in a 156-pin ball grid array that claims to lower board space requirements by 70 percent for makers of VGA cards, set-top boxes, time-shift recorders, notebook PCs, motherboards and add-in cards.
Philips also demonstrated the SAA7108/GeForce2 GTS digital video reference design kit, a full-function video-enabled, AGP card reference design consisting of the SAA7108 and Nvidia Corp.'s GeForce2 GTS digital video daughtercard. According to the companies, the kit speeds development of digital video and 3-D solutions for high-volume PC markets and of digital video recorder products with capabilities such as live-broadcast pause, personalized viewing capture and electronic program guide analysis from off-the-air sources, including the Internet.
Dan Vivoli, Nvidia's senior vice president of marketing, said the GeForce2 GTS and Philips' SAA7108 together support video applications such as real-time, full-perform-ance MPEG-2 encoding, digital time shifting, video editing and TV output for games and DVD.
Martin Maloney, Philips' international product marketing manager, said the SAA7108 lets designers bring digital multimedia content to a variety of converging PC and consumer applications, like time shifting for personal video recording, Intercast, WebTV for Windows, gaming, video capture, video editing, videoconferencing and multimedia creation.
The SAA7108 also supports closed captioning, teletext and Intercast vertical blanking interval (VBI) services, and it supports the latest Macrovision copy protection schemes (Macrovision 7.01), which detect copy protection on input and reapply it on output, Maloney said.
The SAA7108 offers PC-99-compliant video capture and TV-out processing. Its video decoder includes Macrovision detection, a four-line PAL/ NTSC adaptive comb filter, two 9-bit CMOS analog-to-digital converters and a 27-MHz MPEG-compatible clock. Its PAL/NTSC video encoder includes scaling and antiflicker filtering. The decoder uses Philips' line-locked clock decoding, which decodes broadcast signals into ITU-601-compatible color component values. It covers worldwide standards with full autodetection, including PAL and NTSC formats, BGHI and Secam.
In addition to the digital video decoder, the complete video decoder block includes a two-channel analog preprocessing circuit with source selection anti-aliasing filter and A/D converter, a 2-D scaler and H/V filter, an automatic clamp and gain control, and a clock generation circuit.
The SAA7108 PC-Codec is priced at less than $17 in quantities of 10,000.
