One video synchroniser, please - with everything
Crystal Vision's new Synner-VF contains a host of video processing features all on one card
Crystal Vision is releasing a video synchroniser for its new Vision frame system, Synner-VF. The synchroniser combines multiple functions onto one card.
Working with 3Gb/s, HD and SD sources and both AES and analogue audio, the Synner-VF card combines a video synchroniser, tracking audio delay, embedder, de-embedder, audio processor and video proc-amp, and includes flexible delay compensation, handling of Dolby E, signal monitoring and optional fibre input/output. Synner-VF offers more video outputs than any other previous Crystal Vision synchroniser, and takes advantage of the dual reference syncs distributed from the Vision frame, resulting in easier wiring and the option of a backup reference.
Synner-VF can synchronise incoming video signals which are not locked to the local reference, taking its timing from either of the two references connected via the Vision frame and automatically synchronising sources up to one frame apart – and can also compensate for timing delays within the video system.
The ability to cross-lock allows the Synner-VF to use any available timing signals, with a 3Gb/s, HD or SD input referenced to either HD tri-level syncs or SD Black and Burst. The dual common reference on the Vision frame allows an engineer to achieve maximum system reliability by providing main and backup reference distribution throughout the facility. Other advantages to the Vision frame's dual common reference include less wiring, more video outputs and less system distribution amplifiers required to provide reference syncs.
Synner-VF includes tracking audio delay functionality to help maintain lip-sync, running the audio fast or slow to ensure the video and audio stay correctly timed. In addition, Synner-VF offers a flexible range of video and audio delays to help match all the signals – including up to ten frames of video and audio delay to match any big system delays.
Synner-VF can be used as an embedder or de-embedder, making it useful for signal timing applications where external audio needs to be embedded or de-embedded, such as on the station output, station input or before a studio mixer.
For optimising the quality of sound or picture, Synner-VF can be used as an audio or video processor – offering gain adjustment, audio resampling and stereo to mono conversion, as well as a video proc-amp which allows adjustment of the video gain, black level and independent RGB and YUV gains. For those who need to synchronise signals from beyond the local equipment bay, Synner-VF can be given integrated fibre input/output connectivity by fitting the FIP-VF fibre input option, FOP-VF fibre output option or FIO-VF fibre input and output option.
