1. General Description.

The Genesis DEC-6002 eurocard module is a precision adaptive comb filter decoder for
use in any application requiring translation from the analogue composite format to the
digital component format. All processing is carried out in the digital domain to full
broadcast quality, maintaining 10 bit accuracy from input to output. This multistandard
decoder accepts analogue composite sources in PAL, NTSC, PAL-M and PAL-N
standards with automatic detection of input line standard. Error detection and handling
signals are inserted onto the output to allow equipment downstream to verify
transmission integrity. The standard width module (SG6-1) has 4 serial digital outputs
and one looping composite analogue video input.

The DEC-6002 features Leitch’s 134,000 gate ASIC and represents the most
comprehensive comb-filter decoding system, able to gracefully adapt between its
decoding modes. The digital decoder can accept non-mathematical signals and includes
features such as digital 50% sync slicing for robust handling of imperfect sources.
