Issue Date: Mar. 23, 2007
NTSC/PAL-Compatible, 6ch DAC-Equipped Digital Video Encoder with Format Conversion Function
GENERAL DESCRIPTION
The ML86V7655 is an NTSC/PAL compatible digital video encoder. It encodes digital video data such as ITU-R
BT.656 and ITU-R BT.601 to analog video signals.
As digital input, RGB (4:4:4), YCbCr (4:4:4), and progressive scan signals are supported besides generic ITU-R
BT.601 and ITU-R BT.656. As analog video output, RGB and component signals can be output in interlace or
progressive format in addition to NTSC/PAL S-Video and composite outputs. DAC simultaneous 6-channel
output or independent output for each channel can be selected. With the I/P and P/I conversion function, interlaced
digital signals can be output as progressive signals or progressive digital signals can be output as interlaced signals.
The ML86V7656 supports Macrovision copy protection (compliant with version 7.1.L1 for interlace and version
1.2 for progressive).
The ML86V7656 is the Macrovision copy protection support version of the ML86V7655. Some functions or
registers are not available in the ML86V7656. For details, refer to “Notes on the use of the ML86V7656” in the
“VIDEO DATA OUTPUT CONTROL” section. and “Note” in the “REGISTER MAP” Section.
