CVE3

NTSC/PAL/SECAM Video Encoder

CVE3 encodes YCrCb, 4:2:2 digital video into all NTSC, PAL, or SECAM TV standards. CVE3 supports Vertical Blanking Interval (VBI) encoding, including Closed Caption, Teletext, WSS and CGMS-A encoding.
 

Overview

Zoran’s CVE3 NTSC/PAL/SECAM Video Encoder encodes YCrCb, 4:2:2 digital video into all NTSC, PAL, or SECAM TV standards.

CVE3 supports Vertical Blanking Interval (VBI) encoding, including Closed Caption, Teletext, WSS and CGMS-A encoding.

CVE3 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.
