Zoran's CVE3 NTSC/PAL/SECAM Video Encoder is a siliconefficient, 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 component video inputs and with its user friendly GUI enables customers to thoroughly evaluate the performance of Zoran's IP Core products.
