DEC/DES6800 CVBS/SDI Converter
Chapter 1 Introduction
Overview
In this chapter the following modules are introduced ：
DEC6800N
：
Supporting one composite loop output, two SDI output and two SDI outputs with OSD.
DES6800N ： Supporting one composite loop output, one REF loop input, one REF loop output, two SDI
output and two SDI outputs with OSD.
The above modules can be installed in the 6800N Series frame.
General Description of Modules
The DEC/DES6800N is a compact 12-bit decoder and can convert NTSC, PAL and composite signal
into 4:2:2 SDI component signal with broadcasting quality.
The module can handle the signal like the satellite feed and microwave which contains a plenty of noise.
The DES6800 has a built-in synchronizer.
The DEC/DES6800N is controlled by switch on the front panel. The table1-1 gives a general description
of modules.
