Patent DE-4239800-A1 (DE)
Title: Digital decoder for use with digital video cameras - has frequency converter and colour synchronisation circuit generating output for NTSC or PAL format
Inventor: KIM SUNG-HOON
IPC: H04N9/45
Filed: 1992-11-26
Abstract: The digital decoder receives a colour difference signal by a demultiplexer (1) that separates components that are filtered (2) and fed through a transmission frequency converter (3). The signals are modulated (4) for input to a colour decoder (5). A colour synchronising pulse generator (8) receives inputs from a microcomputer via registers (6,7) that contains NTSC and PAL information. The generated burst signal from the pulse generator controls the decoder to suit the NTSC or PAL format. A separate decoder (10) generates a digital luminance signal (Yout). ADVANTAGE - Provides modulation of amplitude and phase of colour difference signals.
