HDMI to Composite Video & Audio Scan Converter
1. Introduction
The VHD-HD2CV is a compact HDMI to composite video & audio
converter. It accepts HDMI or DVI video input up to 1080p and
converts it to composite video. If the input HDMI signal has embedded
audio, it is extracted and output as line level stereo L/R on RCA
connectors.
Underscan presets allow easy capture of the full input video frame.
The converter’s output can be set as either NTSC or PAL, and
features aspect ratio adjustments. The Scan converter features
motion adaptive 3D de-interlacing with noise reduction and motion
adaptive interpolation.
