Systems and methods that may facilitate synchronizing the presentation of a program on multiple devices are disclosed. Synchronization information related to a program may be exchanged via a two-way communications channel. Amounts by which each device may delay its presentation of a program may be calculated and/or exchanged.

The present disclosure relates to a broadcast content production system, a broadcast content production method, and a program that are capable of avoiding occurrence of inconvenience in a broadcast content. The clock accuracy recognition unit recognizes accuracy of a clock of each of a plurality of video sources, and a time difference estimation and correction unit estimates a time difference of a stream from the video source with low accuracy of clock and corrects the time difference. Furthermore, a processing content control unit controls a processing content of production processing of the broadcast content in accordance with the accuracy of the clock of each of the video sources recognized by the clock accuracy recognition unit and with accuracy of time information, of each stream, having being corrected by the time difference estimation and correction unit. The present technology can be applied to, for example, a broadcast content production system using IP connection.

Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.

An audio device includes a signal input interface, a first output interface, a second output interface, at least one processing circuit configured as a buffer control portion, at least one memory configured to store an audio signal. The buffer control portion sets a second reading position at a position that precedes a first reading position of the first output interface by delay time, and, when starting output of the audio signal, writes silent data for the delay time in the memory and sets the first reading position at the head of the silent data.

A method and system is presented for coordinating the transmission of supplemental digital data to accompany broadcast data, and in particular, analog radio broadcasts, among a plurality of broadcasters. The supplemental digital data may provide information about the particular broadcast data being transmitted (i.e. cut data) or may be supplemental to such data (i.e. news, weather and traffic data). The supplemental digital data to be presented is sorted based on particular algorithms which may take into account broadcaster-specified criteria such as target audience, time of day, type of broadcast data presented, and the like. The supplemental digital data may be audio data, visual data, or audio-visual data for presentation with the broadcast data. The supplemental digital data may further be advertisement data. The advertisement data may be sold by the broadcasters or the party coordinating the IBOC transmission of the supplemental digital data. The supplemental digital data may play simultaneously with muted broadcast data or at a user-specified time.

Individual user interactions with a social networking site, which indicate user engagement with particular commercial media content, can be tracked. User group data is generated from the user interactions. Message content related to the particular commercial media content, and schedule information indicating a time at which the particular commercial media content is scheduled for delivery, can be received. A message content delivery time can be determined based, at least in part, on the schedule information. At the message content delivery time, the message content can be delivered to users of the social networking site based, at least in part, on the user group data.

Examples of techniques for targeting campaigns in augmented reality are disclosed, In one example implementation according to aspects of the present disclosure a plurality of augmented reality overlays to be is based on a received trigger image are generated A plurality of targeting groups are then defined. For example, a targeting group may be associated with a targeting campaign aimed at a classification of user, which may be a subset of the plurality of augmented reality overlays.

Techniques for broadcast channel management on a shared communication medium are disclosed. An access terminal may be configured to identify a subframe number associated with a given subframe based not only on a subframe number indicator but also a reference boundary. Conversely, an access point may be configured to set a subframe number indicator for a given subframe based not only on its subframe number but also a reference boundary.
