The CS3 is an automation control station for the I-Caption®, D-Scriptive and ShowTrans systems, synchronizing pre-recorded captions, audio description and translation commentary to live theatrical productions, museum exhibits and movies. Broadcasting up to three separately timed captions or subtitles, the CS3 will also accommodate live, real-time captioning by manually inputting the text via keyboard. The controller advances cues by midi show-control, midi note, midi time code, or SMPTE time code. The software interface makes the system easy to use, maintain and update. The unit is also equipped with an internal modem allowing remote access for software updates, uploading cue changes and downloading log files. Both units can be controlled by the front panel LCD; keyboard, monitor and mouse; or remotely with a wireless PDA.

Synchronization is achieved via a comprehensive software package that reads a variety of midi information from show equipment. A “rehearsal” is run during a performance that synchronizes the slides or audio segments with the appropriate midi fires. This rehearsal can be performed locally through the CS3 keyboard or remotely through a wireless Pocket PC. The CS3's software runs a complex algorithm to automatically find the closest midi fire for each slide or audio segment. This keeps the text and audio in perfect time with the live performance.

The Cue Editor allows the operator to edit the rehearsal after its completion, to delete inaccurate midi fires or change the timing of the slides or audio segments. It can also add looping cues in any part of the program such as sponsorship or advertising before the performance or event.

The user-friendly CS3 automation control stations are designed to supply years of quality performance, delivering clear audio and video at every use, at a reasonable cost.
