santa clara, calif. - Zoran Corp. has launched its Vaddis V DVD multimedia processor for DVD playback (DVD audio) and Web browsing, and has also combined its Vaddis IV-LC DVD decoder and Vaddis CompanionCPU in a chip set for midrange and entry-level DVD designs. The Vaddis V integrates Zoran's DVD-decoding technology with a 135-MHz, 32-bit RISC CPU; a 32-bit, 135-Mips audio DSP; a graphics accelerator; a video processor that can handle three sources simultaneously, and an NTSC/ PAL/480p video encoder and deinterlacer for progressive-scan output. The encoder/ deinterlacer can eliminate the need for an external progressive-scan chip, Zoran said.
"With the Vaddis V, customers can offer new applications taking advantage of the convergence of digital audio and digital imaging within the DVD platform," said Ram Ofir, director of marketing.
The Vaddis V device can decode and encode Dolby Digital, AAC and MPEG Audio Layers 2 & 3 (MP3) compressed digital audio. Its video decoder-processor supports JPEG image browsing.
The chip supports DVD-Video, DVD-Audio, DVD-RW, DVD-RAM, SVCD, CVD, VCD, CD-DA and CD-ROM standards. It also supports DTS decoding, Dolby Digital, Dolby Headphone, Dolby ProLogic, MPEG Layers 1 and 2, MPEG-2 Multichannel, karaoke and 3D Audio, plus meridian lossless packing, linear PCM and watermarking for DVD-Audio players, with up to 192-kHz sampling and 24-bit resolution.
So-called "trick modes" include smooth fast-forward with audio playback, reverse playback and proprietary ZoranZoom video scaling.
Copy protection functions include Copy Protection for Pre-recorded Media and Copy Protection for Recordable Media. Development tools include a real-time OS kit, integrated development environment and application programming interface. Zoran is sampling the Vaddis V now and expects to begin production deliveries in the second quarter. The chip is priced at $18 in lots of 10,000.
The chip set, for its part, is said to reduce to four (from either five or seven) the number of chips needed on a DVD processing board. The Vaddis IV LC includes a DVD decoder, a video encoder, a 54-Mips audio DSP and six-channel audio output capability, which eliminates the need for an external chip. The CompanionCPU includes a 25-MHz, 32-bit RISC CPU; 512 kbytes of flash; embedded SRAM, and peripheral DVD player interfaces that eliminate the need for glue logic. The chip set, along with an audio codec and a 16-Mbit SDRAM, makes a complete board.
The chip set sells for $17 in quantities of 10,000. Both of its chips are manufactured on an 0.18-micron process.
