Description
The Zoran NTSC/PAL encoder core continues a line of highly effi-
cient, 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 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.
