CVE2-PB-1.0

Zoran’s CVE2 NTSC/PAL video encoder core continues a line of

highly efficient, cost effective solutions for the digital video market.

The CVE2 core encodes YCrCb video into all NTSC and PAL stan-

dards with full programmable timing parameters. The carrier fre-

quency and phase provides maximum flexibility. The core also

includes support for Macrovision 7.1.L1, the copy protection used by

DVD and set -top boxes.

This synthesizable intellectual property core accepts YCrCv video as

specified by the CCIR-601 standard or full range YCrCb. All timing

signals are generated within the core, synchronized to an external

27 MHz clock. In master mode the core provides Hblank and Vblank

to the video source. In slave mode Hblank and Vblank are inputs. In

slave mode the core can also be configured to accept multiplexed

YCrCb as specified by the CCIR-656 standard.

The outputs are 6 separate busses for Y, Composite, Chroma, and

RGB. This allows for flexibility in connection and multiplexing to DACs.

Design Considerations

• Low silicon area: approximately 29,000 gates

• Fully synchronous design

• Technology independent. synthezable to most CMOS libraries

Deliverables

• Compilable RTL source code

• Bit accurate C model

• Synopsis synthesis scripts

• Test input files

• IP core documentation
