SYNNER-E HD will simplify the system designs for anybody working in a Dolby E environment.

Put simply, any synchronising, embedding, de-embedding or delay compensation that you're ever likely to want to do with Dolby E, can be done with this product.

SYNNER-E HD will save you money and rack space by combining a video synchroniser, tracking audio delay, embedder, de-embedder and audio processor (along with advanced handling of Dolby E) on one board.

SYNNER-E 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, pass the standard audio through a tracking audio delay to resample it before any audio processing while detecting, synchronising and aligning any Dolby E, and finally re-embed the two groups – outputting video and embedded audio timed to your system.

You can synchronise video containing Dolby E, standard audio or a mixture of the two, with SYNNER-E HD allowing a mixture of Dolby E and standard AES within a single audio group. SYNNER-E HD will separate the Dolby E and standard audio and synchronise both types in the appropriate way before re-embedding the audio.

You can embed or de-embed analogue audio, digital audio or Dolby E.

Add input piggybacks and SYNNER-E HD will accept an untimed feed of video and embed up to two groups of external analogue, digital or Dolby E audio, producing timed video and embedded audio with optional overwriting of audio channels.

With output piggybacks fitted SYNNER-E HD can take an untimed feed of video and embedded audio and produce video and separate analogue, digital or Dolby E audio timed to station syncs.

By fitting one input piggyback and one output piggyback, SYNNER-E HD can be used as a combined video synchroniser and tracking audio delay for independent video and audio.

You can delay the video and standard audio to compensate for Dolby E delays and make the Dolby E position within the video frame earlier if required – it's one of the few products that allow you to realign the guardband.

Or why not use SYNNER-E HD to process your standard audio, with gain adjustment and stereo to mono conversion.

It might be packed with features, but SYNNER-E HD is very easy to operate. Choose your favourite control method – from board edge, an active front panel on the frame, a remote panel, SNMP or the Statesman PC software.

SYNNER-E 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, with the RM33 designed for analogue audio or 110 ohm AES and the RM39 for 75 ohm AES.

VIDEO SYNCHRONISER
Essentially a frame synchroniser allowing any timing difference, SYNNER-E HD additionally offers the advantages of a line synchroniser, with quick recovery of input timing.

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

Ideal for external sources that are not timed to station references, in synchroniser mode SYNNER-E 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-E HD's ability to cross-lock allows it to use any existing timing signals, with an HD or SD input referenced to either HD tri-level syncs or SD Black and Burst .

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-E HD will revert to delay mode.

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 16us and one frame plus approximately 16us.

SYNNER-E 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-E 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-E HD, while up to 16 presets may be stored for later recall.

DOLBY E HANDLING
SYNNER-E HD allows very flexible handling of Dolby E, with Dolby E data automatically detected and processed appropriately.

Up to four sources of Dolby E are possible and can come from a variety of sources: four channels from two audio groups embedded in the video, four channels from two input piggybacks or a mixture of the two.

SYNNER-E HD even allows a mixture of Dolby E and standard AES within a single audio group.

De-embedded Dolby E or input-timed Dolby E from a piggyback will be delayed by the same amount as the video, except for any change required to align it correctly with the output video switching point – meeting the strict requirements recommended by Dolby to allow many more stages of processing. In either case the video can be optionally delayed by one field.

Two Dolby E streams with different timings can be realigned with each other as well as with the video. Output-timed Dolby E from a piggyback will be treated as correctly timed and embedded with minimum processing delay.

Standard audio de-embedded from the same group as Dolby E will be resampled and delayed in the usual way, while output-timed standard audio from the same piggyback as output-timed Dolby E will be routed and embedded with minimum delay.

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

SYNNER-E HD also allows you to delay the video and standard audio to compensate for Dolby E delays, with the option to add one frame of video delay and up to 80ms of fixed audio delay on top of the tracking.

You can also advance the position of the Dolby E within the video frame by using the optional one field delay, and therefore fix any Dolby E that's not correctly aligned.

An audio follow output pulse allows SYNNER-E HD to be used with an external tracking audio delay.

AUDIO EMBEDDING AND DE-EMBEDDING
By fitting piggybacks to the motherboard SYNNER-E HD can include an audio embedder, de-embedder or mixed embedder/de-embedder for analogue, digital or Dolby E 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, the HD-DIP2 for Dolby E 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. Each HD-DIP2 that uses the Dolby E detect removes an input de-embedder.

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.

It's even possible to embed one group and de-embed another – just by fitting the appropriate piggybacks.

The powerful audio routing includes full channel shuffling which allows you to rearrange the audio tracks between the two groups, and audio replace where an input piggyback can overwrite some of the original audio channels from the HD or SD feed.

AUDIO PROCESSING
SYNNER-E HD offers powerful audio processing capabilities for the standard audio.

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.
