CVE4-PB-1.0

Zoran's CVE4 Progressive Out Video Encoder is a silicon-efficient,

high-quality Intellectual Property Core for video IC designs requiring

the progressive scan TV output function. The CVE4 encodes YCrCb,

4:2:2 digital video into the 480p and 576p standards. All NTSC, PAL, or

SECAM TV standards for interlaced output are also supported. CVE4

supports vertical blanking interval (VBI) encoding, including closed cap-

tion, teletext, WSS and CGMS-A encoding. CVE4 also includes sup-

port 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 provides for flexibility in connection and

multiplexing to DACs.

Proven in silicon and shipping in the millions, the CVE4 progressive

out video encoder greatly reduces the risk and time involved when

integrating the progressive out video encoding function into an IC.

When combined with Zoran's Frame-It-1 Video Deinterlacer, CVE4 pro-

vides an industry recognized standard for quality progressive scan out-

put. CVE4 is incorporated into Zoran's own Vaddis DVD playback ICs.
