Abstract: A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system monitors progress of the primary playback system playing back the content. Based on detected progress, the secondary playback system synchronizes playback of supplemental media (such as descriptive audio, closed caption text, etc.) associated with the content on a secondary playback system operated by a user. In response to detecting a scheduled advertisement window during playback of the content on the primary playback system, the secondary playback system discontinues playback of the supplemental media associated with the content on the secondary playback system.

Abstract: A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system plays back supplemental media associated with the content played back on the primary playback system. A media playback function (such as associated with the secondary playback system) monitors playback of the content on the primary playback system. For example, a first processing thread of the media playback function initially synchronizes playback of supplemental media on the secondary playback system with respect to playback of the content on the primary playback system. Based on further monitoring of playing back the content on the secondary playback system, a second processing thread of the media playback function verifies synchronization (and, when needed, initiates re-synchronization) of playback of the supplemental media on the secondary playback system with respect to playback of the content on the primary playback system.

Abstract: The identification, registration, and recordation of individuals are facilitated by allowing the authorities (federal, state, or local law enforcement) and first responders (fire, rescue, hazmat personnel) to collect data at the point of response utilizing a portable computer and suitable software. The portable computer may be equipped with peripherals such as a camera, a biometric collection unit (e.g., fingerprint scanner), a smart card reader, and a GPS receiver to facility gathering and entry of data in the computer. The identity of individuals being questioned by the authorities can be confirmed at the point of questioning with an electronic repository to which the portable computer may be connected.
