IBC 2016 will see the official release of Crystal Visions forward-looking Vision frame system along with its core cards essential for any interface system, including up and down converters, synchronisers, fibre optic transmitters and receivers, audio embedders/de-embedders and distribution amplifiers for analogue and digital video and audio. With its ability to work with higher bandwidth signals such as IP and 4K (as well as SDI), benefits offered by the Vision 3 frame include high packing density of up to 20 cards in 3U, numerous outputs and dual syncs distributed from the frame. There will be the first demonstrations of Crystal Visions IP gateways, which are protocol agnostic and include support for SMPTE 2022. With the biggest range of boards and a choice of frame sizes, the Indigo products on show will include the real-time chroma keyers, which this year are enjoying their greatest popularity to date.

Four of the 12 Vision cards being released in September are distribution amplifiers an essential part of any interface system and traditionally best sellers amongst the Crystal Vision range.

3GDA-VF is a very flexible video distribution amplifier: it can be configured as reclocking or non-reclocking, it will distribute any digital video (3Gb/s, HD and SD) as well as being DVB-ASI compatible, and it is not even limited to video with its ability to distribute MADI (AES10) audio. 3GDA-VF gives more outputs per slot than Crystal Vision has ever offered before: six outputs from a standard single slot rear module (or nine outputs using micro BNCs), and 12 outputs from a double slot rear module. This is Crystal Visions most cost-effective 3GDA with signal reporting to date, as well as the first time the company has offered remote monitoring on a MADI DA.

The VDA-VF distribution amplifier has been designed to provide multiple outputs of analogue sources. With the Vision 3 frame including dual syncs distributed to every card, it is anticipated that the role of VDA-VF will largely be to distribute the station reference to the frame itself, with one VDA-VF able to supply a reference feed to up to 12 Vision frames with 12 outputs being the most that Crystal Vision has ever offered on an analogue video DA. In addition to reference distribution VDA-VF can also be used to distribute SD or HD analogue composite video, with its remotely-adjustable features including gain adjustments of /-3dB and clamp.

There are two Vision cards for the distribution of discrete audio.

DADA-VF is an AES audio distribution amplifier, which provides four outputs per channel when configured as a dual channel device or eight outputs when configured as single channel. The input can be user selected as reclocking or non-reclocking, while DADA-VF includes support for 110 ohm and 75 ohm input and output impedance, 32kHz to 192kHz sample rates and word clock distribution.

AADA-VF is a dual channel analogue audio distribution amplifier which can be used either in mono mode where input 1 goes to all eight outputs, or in stereo mode where inputs 1 and 2 each go to four outputs. With highly robust inputs and outputs, features include audio silence and overvoltage detection and the most extensive gain adjustment Crystal Vision has ever offered, with adjustments over /- 30dB in 0.5dB increments.

In addition to distribution amplifiers, fibre optic transmitters and receivers have always been products that Crystal Vision traditionally sells in large quantities for transporting signals over large distances, and two such cards will therefore be amongst the initial Vision product releases. FTX-VF is a dual channel 3G/HD/SD to fibre transmitter (allowing up to 40 channels in a frame), which can be used with single-mode or multi-mode fibre and meets the SMPTE 297-2006 short haul specification. There are two input loop-throughs per channel (useful for distributing the input video or system checking), while full DVB-ASI compatibility and the ability to fit CWDM lasers to allow many signals to be transmitted down a single fibre link increases the flexibility of the product. Sharing the main benefits of FTX-VF such as the ability to work with single-mode or multi-mode fibre and DVB-ASI compatibility, FRX-VF is the dual channel fibre to 3G/HD/SD receiver from the Vision range, with the two SDI outputs per channel allowing it to potentially double as a distribution amplifier.

Leading broadcasters have standardised on the picture quality of the company s up and down converters, and four of the Vision cards are up/down/cross converters. UP-DOWN-A-VF, UP-DOWN-ATX-VF, UP-DOWN-AS-VF and UP-DOWN-ATXS-VF each offer a different set of features for different applications and budgets, including AFD insertion and reading, audio routing, video and audio delays, timecode conversion, teletext and closed captions handling and downstream video synchronisers.

The final two Vision cards to be released in September have been designed for those using embedded audio.

Working with 3Gb/s, HD and SD sources and both AES and analogue audio, SYNNER-VF combines a video synchroniser, tracking audio delay, embedder, de-embedder, audio processor and video proc-amp to simplify system designs and save engineers money and rack space. In addition to its main function as a sophisticated video synchroniser, it can embed and de-embed a mixture of up to two groups of analogue audio and four groups of AES at the same time, making it ideal for any 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 those that dont need to synchronise, TANDEM10-VF is a dedicated audio embedder/de-embedder with the ability to embed and de-embed a mixture of up to four groups of AES and two groups of analogue audio at th
