Crystal Vision showing latest interface, keying technology18 January 2012
Products on show will include a 2 x 2 switch with full framestore synchroniser on each input (Safe Switch 3G, pictured), along with an audio/video delay designed for correcting large lip-sync errors.
Making its UK exhibition debut, the Safe Switch 3G provides clean and intelligent 2 x 2 switching between two 3Gb/s, HD or SD sources, with a full framestore synchroniser on each input, allowing it to correct for any timing difference between the two inputs. It can be switched manually or 16 different fault conditions can automatically trigger a switch, while loss of reference protection keeps the output valid at all times even on a loss of reference.
AVDELAY 3G is an audio/video delay designed for correcting large lip-sync errors by eye on incoming 3Gb/s, HD or SD signals. The audio and video delay are adjustable independently ,allowing the user to change the relative audio/video timing in either direction, with up to ten seconds of video delay available in SD, five seconds in HD and two seconds in 3Gb/s, along with ten seconds of AES audio delay. The video delay is adjustable in frames, while four delay controls can be assigned to the audio on a mono channel basis.
Up-Down-AS 3G is a synchronising up/down/cross converter which takes all the project-winning features of the popular Up-Down-3G and adds signal timing functionality. Available in five versions to suit a variety of applications, Up-Down-AS 3G allows flexible up, down and cross conversions between 3Gb/s, HD and SD sources and provides an output picture quality that broadcasters standardise on. It also includes special features to allow studios to easily operate in HD and SD at the same time, with its ability to perform two different conversions simultaneously and give out co-timed dual outputs that remain unchanged in format, even if the input changes. To keep the output valid at all times Up-Down-AS 3G has two synchronisers downstream of the converter: one in the 3G/HD path and one in the SD path.
BVE will also see further enhancements to Crystal Vision’s MultiLogo logo keyer. New to the MultiLogo specification is the Preset Import/Export feature, which allows the operator to easily copy settings from one board to another and is suitable for those systems involving multiple logo keyers. The Preset Import/Export feature is available via the MultiLogo Control Software, which is supplied free with the logo keyer, and allows the engineer to choose either to import/export all presets (up to 255 are available) or an individual one. Presets can also be deleted. If a board dies, the Preset Import/Export feature provides a quick way to put in a different board and make it look the same as the original in terms of operation.
The FTX-L3G – a new fibre optic transmitter for transporting 3Gb/s, HD and SD sources over large distances which can be used in conjunction with any of Crystal Vision’s products – will also be on show at BVE. The FTX-L 3G includes two customer-requested input loop-throughs. These loop-throughs can be used to distribute the input video to equipment such as a picture monitor. Alternatively, the loop-throughs can be used for system checking: if a signal path has a good input and a faulty output, the engineer can use the spare output to check each stage of the system without breaking any of the connections, and so work out which equipment or cable is broken. The FTX-L 3G is used with the RM55 frame rear module to access the inputs and outputs.
