  • Page 4: Introduction

    The DEC101S analogue composite or Y/C to serial digital video decoder The DEC101S is a 100mm x 266mm module, which fits in the all standard frames and can be integrated with any boards from the company’s full product range. It uses the single height RM01, double height RM18 and triple height RM02 rear connectors in Indigo and other Crystal Vision frames.

  • Page 5: Operating Modes

    Crystal Vision Introduction Operating modes The DEC101S can operate in the following modes. Input modes Description 8-bit composite The highly tolerant robust inputs are particularly suitable for use with poorly timed sources such as VHS recorders or satellite feeds. 8-bit Y/C (S-video) Each operating mode has its own luminance/chrominance gain and black level settings and both 525 and 625 line standards have separate horizontal and vertical timing settings.

  • Page 6: Statesman

    Running Statesman for the first time The Statesman PC Control System may be run from the Crystal Vision programs folder via the Start menu or by double-clicking on the Crystal Vision.exe file in the installed program directory. When the program runs it will require licence information and an administrator name and password.

    Card edge operation 4 Card edge operation The control of the DEC101S will always follow the last control surface used. For example, if a card edge lever is moved the unit will switch to and remain in the ‘Local Control Mode’. If Statesman or any control panel menu is used, then the unit will switch to and remain in the ‘Remote Control Mode’.

  • Page 25: The Active Output Timing Reference

    Crystal Vision Card edge operation The active output timing reference The horizontal and vertical timing adjustments operate relative to one of two analogue timing references. These are an external reference or an internal free-running clock. When an external analogue timing reference is present serial output timing is maintained relative to the external analogue reference.

  • Page 26: Setting 525 (Ntsc) Setup

    Crystal Vision Card edge operation When the Hpos setting reaches the end of a video line it wraps round and the Vpos setting is changed to provide continuous adjustment. With an external analogue timing reference present the delay through the board depends on these adjustments and the relative timing of the serial input and the analogue reference.
