Product Brief
Description
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.
