FRS-1801 HD/SD Frame Sync

The FRS-1801 is a highly integrated module which offers frame synchronization, and video processing, including color correction and delay, for HD and SD signals in HD/SD hybrid plants. A processing delay of up to 1.3 seconds is available for Dolby E and AC3 encoders/decoders. With the audio processing option, the card can process up to 16 channels (four groups) of embedded audio or eight channels (two groups) of discreet AES inputs/outputs. The FRS-1801 can offer shuffling and downmixing, and provides four AES inputs and four AES outputs.
