  • Page 4: Introduction

    SYNNER-VF is a synchronising audio embedder/de-embedder for use in the Vision 3 rack frames from Crystal Vision. It provides a versatile solution for audio embedding and de- embedding with built-in video delay and synchronising. The SDI video signal passes through a de-embedder and an embedder which allows the extraction and insertion of up to 16 channels (four groups) of audio.
  • Page 5 VANC blanking option. EDH insertion. Supports the following Vision Rear Modules: VR02, VR12 and VR13. Compatible with ‘Vision’ frames from Crystal Vision. Passes all timecode, AFD and subtitling information. SYNNER-VF functional block diagram Block Diagram Description SDI video is cable-equalised, re-clocked and passed through a de-embedder block where up to 16 channels of audio are extracted.

  • Page 6: Video And Audio Delays In Synner-Vf

    Crystal Vision Introduction Audio processing blocks where gain and fixed delay and/or automatic tracking delay for non- Dolby encoded signals, or alignment delay for Dolby E signals are made after resampling. The outputs of the audio processing block are input to two independent 32 x 16 routers which feed the optional plug-in output piggybacks and the embedding block.
  • Page 7 Crystal Vision Introduction to 1 frame. If the reference signal is not locked to the input video, the synchroniser delay will increase or reduce to follow the reference. When the delay goes beyond its minimum or maximum range it will jump instantaneously to the opposite end of its range, either skipping or repeating a frame, possibly causing a motion disturbance for non-static pictures.
  • Page 8 Crystal Vision Introduction 9. This delay is after the frame synchroniser and TAD delays. If either reference is selected as the output timing reference source, the values set by the ‘0-42ms,0-100us and 0-1us’ Delay & output controls in the menu will delay the video and audio signals with respect to the reference.
