1 Introduction
The DEC102S is an analogue composite or Y/C to serial digital video decoder. It contains
a 10-bit synchroniser allowing the serial digital output to be timed to an analogue
reference.
Two main operating modes are supported, 10-bit for professional quality PAL or NTSC
video and 8-bit for less stable PAL or NTSC video, as is often the case with VHS or
satellite feeds.
The decoder is fitted with a line based adaptive comb. It is also designed to accommodate
jittery or damaged signals and will automatically switch to its tolerant 8-bit decoder mode
when a non-stable signal is received.
The main features are as follows:
•
compact single height module
•
converts any composite or Y/C signal to SDI
•
frame synchroniser
•
10-bit adaptive comb plus 8-bit input modes
•
automatic or manual PAL/NTSC standard selection
•
adjustable timing, gain and black level
•
audio follow pulse for audio to video delay tracking
•
loop or terminate external analogue video reference input
•
card edge, Statesman and remote control facilities
