1. Warning:
It is assumed that you have already fully understood the pin assignments of the MPEG decoder in your DVD
player / set-top box and have the skill to do the modification. PMS Video Ltd. is not responsible for any
damage caused during the modification.
2. Introduction:
The BT656Pro SDI Mod. Kit converts the standard parallel BT656 digital video signal generated by the
MPEG decoders of DVD players or set-top boxes to SDI (Serial Digital Interface) signal for video signal
transmission in order to avoid unnecessary digital-to-analog and analog-to-digital conversions which will
cause video quality loss. SDI can keep video signal digital, from the source to the video processor / scaler
then to the digital displays, i.e. the highest video picture quality.
2. Features:
Standard compliant SDI output, compatible with major SDI capture devices
Supports major DVD players and set-top boxes with ITU BT656 video output
Provides 1 SDI output
One BNC connector is pre-installed for easy installation
Provides fully digital output directly from a MPEG decoder to SDI capture card/video processor
Status LED turns on when 27MHz clock signal is detected
30AWG wire wrap wires and power cable are included to facilitate the installation
3. System Requirements:
-The video signal from the MPEG decoder must be ITU BT656 compliant (8-bit video data with embedded
sync + 27MHz video clock).
-DC 5V (usually provided by the DVD player or the set-top box) is required to power the kit.
