Grass Valley Densité Switching & Change-Over

Densité Modules for a Variety of Switching & Change-Over Tasks
DCO-1741/1781 2/4 AES audio change-over with silent switch option
HCO-1822 HD/SD/ASI change-over with clean switch and ALC
HCO-3901 3Gbps/HD/SD/ASI change-over with clean switch and ALC
MCO-5211 Master sync change-over
SCO-1421 Intelligent ASI change-over with probing

The DCO-1741/1781 is a 2/4 AES change-over. The switch is performed electronically by an internal router. In the event of a power failure, the signal is protected by the relays fitted on the rear module, maintaining the integrity of the selected signal at the output. The DCO card allows switching as a regular router, or alternatively the module can perform an audio silent switch between sources using the silent switch software option.

The HCO-1822 is a 2x1 HD/SD/ASI change-over which supports 16 channels of embedded audio and Metadata. Change-overs are performed electronically by the HCO-1822's internal router. The module can perform a video and audio "Clean & Silent Switch" between sources using the CS option. In the event of a power failure, the 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 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 MCO-5211 master sync change-over is designed for use in both serial digital and analog television environment, including AES3 digital audio signals. The use of a change-over unit greatly improves the reliability of a single SPG by having a backup unit ready for takeover in the event of an SPG break down. In order to improve the reliability of the complete system it is essential to have a simple change-over unit. This ensures that the system reliability will not be compromised by the complexity of the change-over unit which then becomes the single point of failure.

The SCO-1421 is a 2x1 intelligent ASI change-over with built-in MPEG-TS probing. Change-overs are performed electronically by the SCO-1421's internal router. In the event of a power failure, the signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output.
