1. Warning:

It is assumed that you have already fully understood the pin assignments of the MPEG decoder in your DVD
player / set-top boxand 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 cableare 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.

4. Specifications:

-Dimensions (H x W x D): 1.5cm x 5cm x 4cm, 1.5cm x 7cm x 4cm including the BNC connectors

-Power consumption: 0.3W

-One Serial Digital Interface (SDI) Output

-One BT656 Input LED Indicator

-PIN assignments:

- LED (D2) lights up when 27MHz
clock signal is detected.

- D0 & D1 are for 10-bits SDI
applications, they are not used for
DVD/set top box SDI modification.

- 8bits (D2-D9).

- D2 is the less significant bit.

- D9 is the most significant bit.

- Clock

- Ground

(Twisted clock and ground cable may
lower the noise of the clock signal)

- +5 V.
