1. Introduction

The HDMI to CV/SV Converter is designed to convert digital signal from HDMI(or DVI + Coaxial) source to analog signal of NTSC or PAL system, with L/Rstereo audio. Besides S-Video and Composite Video outputs, it also provides
one bypass HDMI output to deliver the original signal, and a Coaxial output
to send S/PDIF digital audio to audio amplifier. The product provides aconvenient application that allows the users to watch high definition
movie while recording it (in standard resolutions 480i or 576i) to DVR or VCRmachine.

2. Features

HDMI 1.2, HDCP1.1 and DVI1.0 compliant
Converts video signal from HDMI source to NTSC or PAL signal selectable
Converts digital audio from HDMI source to analog stereo audio
Accepts a wide range of HDTV input resolutions, from 480p to 1080p@60Hz(except 1080p@24Hz) and PC from VGA@60Hz to UXGA@60Hz
 Video and audio conversion / bypass scenarios:
Note:  Sources’ signal also need to disable 1080p@24Hz resolution in order toavoid image corruption.
 When HDMI input source end is not displaying full screen (i.e. letterbox/pillbox image) then the output display end may come out withwrong size or position images. Hence, input source must set on fullscreen first before powering on the converter and set the input source
to YCbCr by entering into DVD/PS3/BD’s OSD menu and set the HDMI
color space on YCbCr will resolve the problem.

Video from DVI source and audio from Coaxial source
DVI -> Bypass, output original video from DVIOUTPUT C

COAXIAL -> Output digital audio from Coaxial
CV + L/R -> Output analog video converted from DVI, L/R mute***SV + L/R -> Output analog video converted from DVI, L/R mute**** In the scenario of INPUT/OUTPUT A, the audio signal from Coaxial input will notbe used.
** DVI input or output can be applied by using HDMI to DVI adapter or cable ofsimilar function.
*** Analog L/R audio outputs are not available when the audio input is Coaxial,
please connect the analog audio from source to your speakers directly.
● When the signal from HDMI or DVI source is protected by HDCP (Highbandwidth Digital Content Protection), the HDMI or DVI display needs tosupports HDCP to be able to show picture.
