Crystal Vision introduces SYNNER-E HD synchronizer
Crystal Vision introduced SYNNER-E HD, a video synchronization tool designed to simplify system design in Dolby E environments. Shipping now, SYNNER-E HD combines a video synchronizer, tracking audio delay, embedder, de-embedder and audio processor along with advanced handling of Dolby E and delay compensation on one 100mm x 266mm board.
SYNNER-E has the ability to both synchronize incoming video signals that are not locked to local reference, and to compensate for timing delays within the video system. Synchronizer features include allowing any timing difference, quick recovery of input timing and the ability to cross-lock. SYNNER-E HD syncs at three separate points, avoiding picture disturbances for switches between mistimed sources or that occur in the vertical blanking.
Dolby E data is automatically detected and processed appropriately. SYNNER-E HD can synchronize video containing Dolby E, standard audio or a mixture of the two. The system also allows a mixture of Dolby E and standard AES within a single audio group. It can separate Dolby E and standard audio and sync both types before re-embedding the audio.
SYNNER-E HD allows the embedding or de-embedding of external analog, digital or Dolby E audio. Up to four sources of Dolby E are possible and can come from a variety of sources. The system can also 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 40ms of fixed audio delay on top of the tracking.
The SYNNER-E HD includes sophisticated audio routing. The 16 x 8 mono router allows both channel shuffling and audio replace. The audio processing for the standard audio includes individual gain control adjustable in 0.1dB steps, and stereo to mono conversion.
Designed in a modular format for Crystal Vision's standard frames, up to 12 synchronizers will fit in 2U. Control is flexible, with options including board edge switches, an active front panel on the frame, a remote panel located in a different room or the Statesman PC software.
