The HCO-3901 is a 3 x 1 3Gbps/HD/SD/ASI change-over which support 16 channels of embedded audio and Metadata. The module can perform a video and audio Clean and Silent Switch between sources using the CS option. In the event of a power failure, the PGM signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output. Relays are fully controllable via GPI.
The HCO-3901 generates audio/video fingerprints. In combination with other cards streaming fingerprints for the same signals, an optional module in iControl can measure and report lip sync errors through the entire chain of a broadcast facility.
