SYNNER HD will simplify your system design.

As flexible as you need it to be, SYNNER HD combines on one board the traditional functionality of five different products - video synchroniser, tracking audio delay, embedder, de-embedder and audio processor - giving enhanced flexibility to the system designer while bringing significant cost and rack space savings.

SYNNER HD can be used in many different ways, and is ideal for any application involving untimed HD or SD video and associated audio, whether that audio is already embedded or needs to be embedded.

Its first and foremost use is as a straightforward embedded audio synchroniser.

SYNNER HD can both synchronise incoming video signals which are not locked to the local reference and compensate for timing delays within the video system.

With timing coming from either SD or HD analogue syncs, it will synchronise the video, de-embed up to two audio groups, mono route the audio channels and pass them through a tracking audio delay resampling them to match the synchronised video, apply any audio processing and then finally re-embed the two groups - outputting video and embedded audio timed to your system.

By adding input piggybacks SYNNER HD can accept an untimed feed of video and embed up to two groups of external analogue or digital audio, producing timed video and embedded audio with optional overwriting of audio channels.

Used like this, SYNNER HD offers a complete input stage for asynchronous HD or SD video and analogue or digital audio into an embedded audio system, making it ideal for audio and video lines in.

Perhaps you have an embedded feed that you want to synchronise and break into separate video and audio. With output piggybacks fitted SYNNER HD can take an untimed feed of video and embedded audio and produce video and separate analogue or digital audio timed to station syncs.

By fitting one input piggyback and one output piggyback, SYNNER HD can be used as a combined video synchroniser and tracking audio delay for independent video and audio. In this case the audio can be fully processed and delayed to match the synchronised video.

Essentially a frame synchroniser allowing any timing difference, SYNNER HD additionally offers the advantages of a line synchroniser, with a short minimum delay of 2us and quick recovery of input timing.

SYNNER HD has two operational modes: synchroniser and delay line.

Synchroniser mode is ideal for external sources that are not timed to station references such as satellite or remote contribution feeds. In synchroniser mode SYNNER HD takes its timing from the external analogue reference and will automatically synchronise sources between 0 and 1 frame, fixing any incorrect frame rates plus any delays.

SYNNER HD's ability to cross-lock means that an HD or SD input can be referenced to either HD tri-level syncs or SD Black and Burst - therefore allowing it to use any existing timing signals.

The output timing relative to the reference can be adjusted through an entire frame using horizontal and vertical settings. Should the reference be removed or the board powered without a connected reference SYNNER HD will run in delay mode locked to the main input.

Delay mode is ideal for when the frame rate is correct but the source has been passed through other equipment and therefore been delayed for a few lines. With full adjustment of vertical and horizontal timing available, the fixed delay can be set between 2us and one frame.

SYNNER HD offers a powerful synchronising system, synchronising at three separate points: at the start of the field or frame, just after the switching point, and at the start of the active field or frame. This allows it to avoid picture disturbances for switches on the input that are between mistimed sources and that occur in the vertical blanking.

Manual freeze allows SYNNER HD to be used as a simple still store, with the type of freeze selected from frame, field 1 or field 2.

Automatic freeze is available when input fails through loss of signal, with alternative responses selectable as blue screen, black screen, delay then blue or delay then black.

Indication is also given if the delay between the input video and external reference is shorter than the blanking period of the input video.

A TTL level pulse allows an audio delay to track the video delay through SYNNER HD, while up to 16 presets may be stored for later recall.

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.

Up to 20ms of fixed audio delay can be added on top of the 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.

A synchroniser delay pulse output also allows SYNNER HD to be used with an external tracking audio delay.

Need to embed or de-embed? No problem. When it comes to audio, SYNNER HD's flexibility allows it to be configured in many different ways.

Simply by fitting piggybacks to the motherboard SYNNER HD can include an audio embedder or de-embedder for analogue or digital audio.

This allows you to embed one or two groups of audio (with optional overwriting or shuffling of existing audio), or de-embed one or two groups of audio timed to your system.

So which piggybacks do you need?

To embed external audio, use the HD-DIP2-RS piggyback for AES and the HD-AIP2 for analogue audio.

The HD-DIP2 can be used to embed AES when you want to synchronise the video but embed external audio without delaying it. The HD-DIP2 always bypasses the tracking audio delay, and can be used for applications when you have an external video feed and you want to add local audio or Dolby E which is already timed to the synchronised feed. (Although SYNNER HD can be used for Dolby E in this way, the SYNNER-E HD is more suitable for this application.)

To de-embed audio, use the HD-DOP2-75 for 75 ohm AES, the HD-DOP2-110 for 110 ohm AES and the HD-AOP2 for analogue audio. One piggyback is required for one audio group and two piggybacks for two audio groups.

Of course you can always embed one group and de-embed another by fitting the appropriate piggybacks. Just change the piggybacks to change the product.

The audio routing is as powerful as you need it to be. Full channel shuffling is provided by a 16 x 8 mono router which will allow you to rearrange the audio tracks between the two groups. With audio replace an input piggyback can be used to overwrite some of the original audio channels from the HD or SD feed.

SYNNER HD also offers powerful audio processing capabilities.

The audio level can be increased or decreased to match the rest of your system, with each mono audio channel offering individual gain control, adjustable between +3dB and -3dB in 0.1dB steps.

Audio channels can be muted, while stereo to mono conversion helps those broadcasting a multi-language service.

Forward error correction ensures audio quality is maintained, while a headphone socket on the front of the board can be used to preview the audio sources.

Easy to operate, SYNNER HD uses an intuitive board edge interface which, using two select buttons, a shaft encoder and a display, allows you to instinctively and quickly locate any option from menus structured in the most logical way possible.

Control can additionally be from an active front panel on the frame, a remote panel located in a different room, SNMP or the Statesman PC software, with Statesman's user-friendly GUI making it very easy to configure the board to your requirements.

SYNNER HD fits in the standard frames (available in 4U, 2U, 1U and desk top box) and can be used with two frame rear modules to access all the inputs and outputs: select the RM33 if you're using analogue audio or 110 ohm AES and the RM39 if you're using 75 ohm AES.
