VIDEO A/D CONVERSION

Features The ASV12 is an analog to digital converter which converts analog composite signals to serial digital (SDI). The ASV12 has a frame synchronizer, video proc-amp, VI-inserter and an adaptive 5-line comb filter for signal enhancement. A 2 group embedder is part of the internal processing core and can be enabled by using an ADD-ON card like the ADC20/24 and DIO24.

Complementary cards: ADC20, ADC24, ADL24, DIO24, DIO48, DLA44, DLA43

Applications

High quality decoding in MCR input lines (together with timing correction) CVBS and analog audio decoding and embedding (requires an additional ADC20)
