Abstract

The present invention provides for a system and method of wirelessly triggering portable devices to provide a user with audio and/or visual information related to a show or attraction, for example, or for the purposes of captioning, language translation, assistive listening, and descriptive audio. As a person moves about a venue, a portable device receives signals from transmitters at venue locations. Transmissions may be via infrared or radio signals. The receiving device decodes each signal as a venue location, event time, or device trigger. The receiving device processes the signal and its memory to start a presentation on the device. The portable device memory contains audio, text, graphics, and/or visual content; device playback may contain one or many of these stored contents. The stored content may be synchronized with the user'"'"'s location, time of travel, time of day, time of a show, or an event in a show. Stored content may be in one or many languages. Presentation of stored content on the portable device may also be altered by user preference, stored logic constraints, automatic learning of user behavior, or user interaction with other devices.

Claims

1. A method of providing additional audio/video information during a movie to viewers in a theater, comprising:

providing a viewer of a movie with a portable device, the portable device being pre-programmed with data representing audio/video information related to the movie;

wirelessly transmitting at least one time code during the movie, the time code being a time from a start of the presentation;

receiving the at least one time code at the device;

processing the at least one time code to determine where to start audio/video information; and

displaying the audio/video information on the device in synchronization with the movie.

2. The method of claim 1 wherein the information related to the movie comprises deleted scenes.

3. The method of claim 1 wherein the information related to the movie comprises commentary about the movie.

4. The method of claim 1 wherein the information related to the movie comprises a separate audio track for the movie.

5. The method of claim 4 wherein the audio track is in a foreign language.
