The flexibility of SYNNER144 is guaranteed to simplify your system design.

You can use it in three different ways. Without any piggyback fitted, SYNNER144 becomes a synchroniser with tracking audio delay for video containing embedded audio, and allows audio shuffling.

With an input piggyback, it becomes a synchroniser with tracking audio delay and embedder, allowing you to overwrite or shuffle existing audio.

With an output piggyback, it becomes a synchroniser with tracking audio delay and de-embedder, allowing you de-embed audio timed to your system.

The audio you embed or de-embed can be analogue or digital. It works with two groups of embedded audio, too. Such is the flexibility of SYNNER. One product - many uses.

GETTING DOWN TO BASICS

SYNNER144 combines a video synchroniser with tracking of two audio groups, embedder or de-embedder and audio routing.

The logical combination of Crystal Vision's famous embedder and synchroniser technology, SYNNER144 provides many functions in one product, reducing the number of boards you need to buy and saving you rack space and money.

The increasing use of embedded audio, especially multiple group operation, combined with the board's flexibility makes SYNNER ideal for a very broad range of applications.

The flexibility comes as a result of being able to use SYNNER in three different ways: without a piggyback, with an input piggyback or with an output piggyback.

SYNNER can be used in a wide variety of places within a broadcast system such as on the station input or output, after a routing switch where the sources are several lines apart, or in installations using the latest generation of broadcast VTRs which can record up to two groups of embedded audio.

WHAT DO I NEED?

Buy the basic 100mm x 266mm SYNNER144 motherboard and then select one piggyback providing an external input or output from a choice of six to suit your application.

If you're embedding or de-embedding analogue audio you must also fit an HD-DCDCV18 PSU.

USING SYNNER: WITHOUT A PIGGYBACK

Without any piggyback, SYNNER144 can accept an untimed feed of video containing up to four stereo pairs (two groups) of embedded audio.

It will time the video and embedded audio to your system and can also change the way the stereo pairs are arranged in the embedded audio, providing a 4 x 4 stereo router. See block diagram...

USING SYNNER: WITH AN INPUT PIGGYBACK

By fitting an input piggyback (HD-AIP2, HD-DIP2 and HD-DIP2-RS), SYNNER144 can accept an untimed feed of video and separate analogue or digital audio and produce timed video and embedded audio, with channel swap and replace. The input audio can be timed to the station or timed to the incoming video.

Tracking audio delay can be applied to the input audio to track the delay of the video synchroniser although this can be bypassed if the audio is timed to the station reference.

In addition to audio shuffling, SYNNER144 allows the overwriting of individual stereo pairs, and can create a new group of embedded audio or overwrite some or all of what is already present. (If you need to split the stereo pairs, you should additionally use the TANDEM range of products.)

Used in this way, SYNNER offers a complete input stage for asynchronous SDI and analogue or digital audio into an embedded audio system. See block diagram...

USING SYNNER: WITH AN OUTPUT PIGGYBACK

With an output piggyback fitted (HD-AOP2, HD-DOP2-75 and HD-DOP2-110) SYNNER can take an untimed feed of video and embedded audio and produce video and separate analogue or digital audio timed to station syncs.

A 4 x 6 stereo router allows you to select which stereo pairs you wish to de-embed. See block diagram...

SYNCHRONISER

The excellent synchroniser features include a short minimum delay of 3.8us and the avoidance of picture disturbance by fast locking after an up-stream switch.

SYNNER144 has two modes of operation, synchroniser and delay line.

In synchroniser mode it will sort out any incorrect frame rates plus any delays by taking its timing from the external analogue reference and will automatically synchronise sources with or without embedded audio between 0 and 2 fields.

Delay mode is ideal for when the frame rate is correct but the source has been passed through equipment and therefore been delayed for a few lines, with timing derived from the SDI input.

Automatic freeze is available when input fails through loss of signal. The user can specify to show the last good field repeated before picture failure, the whole frame in which failure happened (useful for diagnostic purposes) or a black or blue screen. It can also be selected to freeze the picture for one second and then go to black or blue.

Manual freeze allows SYNNER144 to be used as a simple still store.

The current board settings including routing and delay can be saved in one of 16 locations, allowing the user to store and recall up to 16 different configurations for later use.

TRACKING AUDIO DELAY

The internal audio delay tracks the video delay, running the audio fast or slow to ensure the video and audio stay correctly timed and to avoid lip sync errors.

The user can also add 88ms of fixed audio delay on top of tracking to compensate for early audio.

Predictive tracking can be used to minimise the offset between audio and video delay when video frames are dropped or repeated. An audio follow output pulse also allows SYNNER to be used with an external tracking audio delay.

DOLBY E

SYNNER can be switched to Dolby E mode to preserve Dolby E encoded audio embedded in the SDI input through the synchronisation process, allowing it to pass transparently through the board. Dolby E in AES form cannot be embedded using SYNNER144 - use one of the TANDEM models instead.

MONITORING

SYNNER makes it easy for you to check your various sources. An analogue PAL/NTSC composite output, timed to the reference, is available for video monitoring, while a headphone socket on the board allows you to listen to the individual analogue audio stereo pairs.

QUALITY CONTROL

SYNNER144 features Crystal Vision's robust embedded audio protection.

Sophisticated audio error masking and contiguous packing of audio data ensures correct transport of multiple audio groups. A variety of sophisticated techniques are employed to protect and minimise the effects of cuts to untimed and asynchronous SDI, SDI corruption and TRS loss in the SDI signal. The selected audio groups are not affected by the frame drops or repeats of video synchronisation.

CONTROL

Control is as flexible as SYNNER itself.

Adjustments can be made from the board edge, an active front panel on the frame, a remote control panel located in a different room, SNMP or the Statesman PC Control System.

Statesman's user-friendly GUI makes it very easy to configure the board to your requirements with, for example, audio routing set by simply clicking the squares on a grid.

INPUTS AND OUTPUTS

SYNNER144's flexibility is further increased by being able to use the board with four different frame rear modules, to obtain the exact configuration required. These are the RM04, RM07, RM26 and RM30.

SYNNER fits in the standard Crystal Vision frames allowing it to be combined with any other interface product from the range.

The single slot RM04 allows the maximum number of boards in a frame and can be used with either analogue audio or 110 ohm AES. It is the favourite rear module for input/output piggyback configurations where monitoring is not a requirement.

The two slot RM07 should be used for 75 ohm AES applications.

The two slot RM26 can be used with either analogue audio or 110 ohm AES. It fits less boards in a frame than the RM04, but gives composite video monitoring and both Black and Burst and SDI loop-throughs. It can be used for applications with no piggyback, an input piggyback or an output piggyback.

The single slot RM30 has no audio connections and is the default rear module for applications without a piggyback. If the extra SDI and analogue outputs and the SDI loop-through are required, the RM26 should be used instead.
