Abstract
The present invention achieves wireless delivery of media streams to portable devices for providing media information related to a show or attraction for the purposes of captioning, language translation, and assistive listening. As a person moves about a venue, the device receives infrared or radio signals from transmitters at venue locations. The device decodes each signal as venue location, event time, or device trigger for presentation on the device. The device memory contains audio, text, graphics and device playback may contain one or many of these stored contents. The stored content is synchronized with the user's location, time of travel, time of day, time of a show, or an event in a show and may be in one or many languages. Presentation of stored content on the device may also be altered by user preference, stored logic constraints, automatic learning of user behavior, or user interaction with other devices.
