SIMPLIFYING SYSTEM DESIGNS WITH THE SYNNER-E 3G MULTI-FUNCTIONAL SYNCHRONISER (September 2009)

SYNNER-E 3G will simplify system designs for those working with 3Gb/s, HD or SD sources in AES or Dolby E environments.

With the ability to work with four groups of audio, this ultimate device for all embedding, de-embedding and timing requirements combines a video synchroniser, tracking audio delay, embedder, de-embedder, audio processor and video proc-amp on one 100mm x 266mm board, and includes special features for flexible processing of Dolby E.

SYNNER-E 3G can both synchronise incoming video signals which are not locked to the local reference and compensate for timing delays within the video system. The acclaimed synchronising features include full horizontal and vertical timing adjustment, cross-locking, three point synchronising and fast locking after an upstream switch to avoid picture disturbance.

Also included is a video proc-amp for picture optimisation, with adjustment of the video gain, black level and independent YUV gains.

With bi-directional digital audio inputs and outputs on the board, up to eight channels of external AES or Dolby E can be embedded or de-embedded in any combination, while flexible audio routing comes from a 32 x 32 router which allows the shuffling and overwriting of any channels. 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 3G includes very powerful Dolby E features. It will synchronise video containing Dolby E, standard audio or a mixture of the two, and allows a mixture of Dolby E and standard AES within a single audio group, separating the Dolby E and standard audio and synchronising both types in the appropriate way before recreating the audio. The video and standard audio can both be delayed to compensate for Dolby E delays and a selectable one field video delay can be used to correctly align the Dolby E data with the video frame.

SYNNER-E 3G offers powerful audio processing capabilities for the standard audio, including individual gain control, channel muting and stereo to mono conversion.
