“All channels televising live events are well advised to guard against unexpected interruption," comments Ananth Sam, Medialogy Broadcast's Sales Director. "Our role in this project was to research the available technical options and recommend a solution that would allow the network's production team to respond quickly and decisively in the event of unexpected interruption during a live transmission.

"Crystal Vision has achieved a high reputation for the reliability, versatility and cost-efficiency of its signal processors. The solution we recommended and have implemented allows a live 1080i50 HD-SDI signal to be delayed up to 24 seconds. That gives the operators sufficient time to prevent unwanted video or audio content being transmitted.

"One of the deciding factors in the choice we made was the flexibility, speed and efficiency of Crystal Vision's SBB-4 hardware controller. This has four assignable pushbuttons which encourage fast, confident and decisive action. It is very straightforward to use, including a series of content cleaning tools to match specific productions. Configuration and operation can be performed onsite or via a securely internet-connected remote location.

"Our recommendation was accepted so we liaised with Crystal Vision to deploy the system and provide training to the network's transmission team. The Vision 3 frame also provides space to accommodate additional Crystal Vision processors if these are required at any time in the future."

"With its extensive video and audio cover options, M-CLEANIT is ideal for preventing expletives, obscene gestures, wardrobe malfunctions, bloopers, coughing fits and technical problems from making it to air," adds Stewart McGhie, Crystal Vision's Head of Sales. "The operator can choose to blur the programme video, with a variable user-defined blur amount and a blur fade time of up to 10 seconds, or can make the video black or blue or show colour bars. It is also possible to clean-switch to the live programme, jumping ahead of the offensive content. There are also two audio cover options: the main programme audio feed can be muted, with individual channel selection and a fade time of up to ten seconds, or the operator can switch to a safe audio source.”
