CVE3-PB-1.0

Zoran's CVE3 NTSC/PAL/SECAM Video Encoder is a silicon-

efficient, high-quality Intellectual Property Core for video IC designs

requiring the TV output function. The CVE3 encodes YCrCb, 4:2:2

digital video into all NTSC, PAL, or SECAM TV standards. The

CVE3 supports vertical blanking interval (VBI) encoding, including

closed caption, teletext, WSS and CGMS-A encoding. CVE3 also

includes support for Macrovision 7.1.L1, the copy protection scheme

used in DVD players and set-top boxes. Six separate output busses

for Y, Composite, Chroma, and RGB provide for flexibility in

connection and multiplexing to DACs.

Proven in silicon and shipping in the millions, the CVE3 video

encoder greatly reduces the risk and time involved when integrating

the video encoding function into an IC. Zoran’s video encoder

technology is incorporated into its own Vaddis DVD playback and

COACH digital camera ICs.

VIP-II Demonstration System

The VIP-II is an FPGA demonstration system for Zoran's IP Core

products. The VIP-II accepts composite video, S-video and compo-

nent video inputs and with its user friendly GUI enables customers

to thoroughly evaluate the performance of Zoran's IP Core products.
