Caption Display - Features

These systems are used in a variety of environments where it’s more convenient to have the closed captioning displayed outside of the normal on-screen viewing area.

  • Noisy or crowded environments.
  • Quiet environments.
  • Large spaces like museums, theatres and convention halls, information kiosks, churches, trade shows, airports, and exhibition hotels.

Problems and Solutions

Problem: On-screen captioning obscures part of the picture. Many people feel that the aesthetics of the on-screen image are seriously compromised by the captions.

Solution: Our Closed Caption Display Systems keeps the video image clear by moving the closed captions off the screen. It works by pulling off the hidden closed-caption encoded onto a video signal and sending it to our easy-to-read LED displays.

Problem: Legibility problems occur with regular captioning. When the monitors are placed at a distance from the viewers, the captioning can become very difficult to read. There can also be line-of-sight problems with people in the front blocking the view of those behind them. Because of these shortcomings, closed captioning is sometimes turned off altogether.

Solution: The CD-2000 comes with highly visible matrix LED displays providing excellent visibility from a distance. The captioning systems can also be placed away from the video to provide much better visibility to all viewers.

Problem: Displaying multiple captions in different languages simultaneously.

Solution: The video loop through feature is standard on all of our systems and provided the ability to display multiple languages on separate displays providing a wider audience for your presentation.

Caption Display - Systems

Compusult has five models of the Closed Caption Display Systems available. All are complete, ready-to-run remote systems. The varying feature is the size of the character height that determines the maximum viewing distance from the units.

Caption Display Units

Caption Display Units

All our Caption Display Systems work by extracting the closed caption (Line 21) encoding from the video signal and displaying it to a high density LED display. The systems will present all ASCII characters that can come from baseband video sources with embedded Line 21 closed captions, an EIA-608B serial data feed or from the Compusult Caption Display software. This leaves the video picture free of the captioning information for improved visibility and unobstructed viewing. These systems are used in a variety of environments where it’s more convenient to have the closed captioning displayed outside of the normal on-screen viewing area.

Captioning Software

Compusult's Caption Display software allows you to transcribe the spoken word during meetings, live performances or presentations using voice recognition software, keyboard entry, and/or prepared text files. It also integrates directly with our Caption Display units to provide high visibility text for attendees that are hard of hearing, or translated versions of spoken words for audiences with different primary languages.
