Product Brief

Description

Zoran's CVE5 High Definition Video Encoder is a silicon-efficient,

high-quality Intellectual Property Core for video IC designs requiring

the high definition TV encoding. The CVE5 encodes YCrCb, 4:2:2

digital video into the 720p, 1080i, 480p and 576p standards. All

NTSC, PAL, or SECAM TV standards for interlaced output are also

supported. CVE5 supports vertical blanking interval (VBI) encoding,

including closed caption, teletext, WSS and CGMS-A encoding.

CVE5 also includes support for Macrovision 7.1.L1, the copy protec-

tion scheme used in DVD players and set-top boxes. Six separate

output busses for Y, Composite, Chroma, and RGB provide for flexi-

bility in connection and multiplexing to DACs.

The CVE5 High Defintion video encoder greatly reduces the risk and

time involved when integrating this function into an IC. When com-

bined with Zoran's Frame-It-1 Video Deinterlacer, CVE5 provides an

quality solution for high definition video encoding.

Features

• 720p, 1080i, 480p and 576p standards supported

• Encodes 4:2:2 YCrCb into all variations of NTSC, PAL or SECAM

interlaced TV standards for interlaced output

• Simultaneous output of composite video, S-video and component

video supported

• Dual chroma paths for optimal output of both composite video and

S-Video component video

• CCIR 601, 604 and 656 and SMTPE 253 standards supported

• Macrovision 7.1.L1 copy protectionn

• 47-tap luma filter

• Outputs 10-bit data to DACs

• Vertical Blanking Interval (VBI) encoding support

• Closed caption, teletext, WSS & CGMS-A encoding

• Uniform 54 MHz clock; fully synchronous design

• 4x oversampling of luminance and chrominance filter for interlace mode

• 2x oversampling for progressive scan mode

• Process technology independent "softcore"
