CVE2

NTSC/PAL Video Encoder

CVE2 encodes YCrCb, 4:2:2 digital video into NTSC or PAL TV standards and includes support for Macrovision 7.1.L1, the copy protection used by DVD and set -top boxes.
 

Overview

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 standards with full programmable timing parameters. The carrier frequency 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 YCrCb 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.
