A method for facilitating targeted secondary content delivery to a user is envisaged. The primary content is broadcast on a television accessible to a user, followed by targeted delivery of relevant secondary content onto a handheld device of the user. The secondary content deemed as being relevant to the primary content is delivered in an unobtrusive manner without altering the viewing experience of the primary content, only after verification of the viewership of the primary content. The secondary content deemed as relevant to the primary content is transmitted to a handheld device accessible to the user thereby not altering the viewing experience corresponding to the viewing of the primary content on the television. The secondary content is delivered to the handheld device via electromagnetic waves, preferably radio waves without necessitating an active internet connection for the handheld device, and without necessitating the user to remain logged-on to the handheld device.

A portable terminal includes a receiving unit which receives content information, an external device communication unit which conducts communication with an external information device, a display unit which displays the content information received by the receiving unit, an acquiring unit which acquires identification information identifying the content information displayed by the display unit, an operation unit which receives an operation indication from a user, and a control unit which conducts control such that if a transmission indication of the identification information is received by the operation unit while the content information is being displayed, the identification information acquired by the acquiring unit is transmitted to the external information device and the display of the content information by the display unit is terminated.

The Automated Content Upload System networks a plurality of aircraft together when they are parked at the gates of an airport. Communications among the aircraft are guided by a Content Manager, resident at or near the airport, which maintains data representative of InFlight Entertainment Content presently stored on each aircraft and the list of scheduled InFlight Entertainment Content available on each aircraft. The Content Manager guides the exchange of InFlight Entertainment Content among the aircraft, as well as from the Content Manager to the aircraft, to automatically distribute InFlight Entertainment Content to the aircraft efficiently and timely. This process includes the ability to multicast data from the Content Manager to multiple aircraft in a single transmission, obtaining content delivery efficiency, populating multiple aircraft via a single transmission from the Content Manager. Furthermore, the Content Manager can supplement this process via transmissions to the aircraft in flight over the Air-To-Ground link.

An electronic device that reduces relative drift is described. In particular, an interface circuit in the electronic device may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may store the adjustments to the clock circuit. Furthermore, when a wireless reset occurs, the interface circuit may adapt the clock circuit based on the stored adjustments to reduce the relative drift while the interface circuit restores frequency lock with the second clock based on additional packets with additional transmit times that are received from the second electronic device.

A digital broadcast network is provided in which multiple original experiences powered by the same data is created. A server software intelligently handles delivery of data so that the data can be utilized by several different client-side applications at substantially the same time. Through filtering of large amounts of data and creation of a universal format, this data can be used by devices capable of receiving a digital broadcast stream.
