A method is provided for synchronizing the playback of a digital audio broadcast on a plurality of network output devices by inserting an audio waveform sample in an audio stream of the digital audio broadcast. The method includes the steps of outputting a first unique signal as part of an audio signal which has unique identifying characteristics and is regularly occurring, outputting a second unique signal so that the time between the first and second unique signals must be significantly greater than the latency between sending and receiving devices, and coordinating play of audio by an audio waveform sample assuring the simultaneous output of the audio signal from multiple devices. An algorithm in hardware, software, or a combination of the two identifies the audio waveform sample in the audio stream. The digital audio broadcast from multiple receivers does not present to a listener any audible delay or echo effect.

A computer implemented method and system simultaneously distributes content data streams (CDSs) of multiple content formats, for example, live cable television content, gaming content, social media content, user generated content, etc., to one or more computing devices. An interactive content distribution platform (ICDP) receives user selections of the CDSs and the content formats via a graphical user interface (GUI) and receives one or more CDSs in one or more content formats from multiple content sources based on the user selections. The ICDP synchronizes the CDSs by encoding the CDSs into a common data format and adjusting a transmission rate of the CDSs. The ICDP simultaneously transmits and displays the synchronized CDSs in one or more configurable windows on a display screen of each computing device at configurable time instances via the GUI. The ICDP facilitates interactions and initiates transactions between computing devices during the simultaneous display of the synchronized CDSs.

A method is provided for synchronizing the playback of a digital audio broadcast on a plurality of network output devices by inserting a control track pulse in an audio stream of the digital audio broadcast. The method includes the steps of outputting a first control track pulse as part of an audio signal which has unique identifying characteristics and is regularly occurring, outputting a second control track pulse so that the time between the first and second control track pulses must be significantly greater than the latency between sending and receiving devices, and coordinating play of audio at the time of the occurrence of the transmission of the second control track pulse assuring the simultaneous output of the audio signal from multiple devices. The control track pulses have a value unique from any other portion of the audio stream. The digital audio broadcast from multiple receivers does not present to a listener any audible delay or echo effect.

Apparatus for interactive broadcasting comprises: an in step device for determining predetermined times in a broadcast relevant to user interaction; a content insertion device for inserting interactivity content for sending over a network to users for interaction at the predetermined times; and an embedding unit for embedding timing control into the interactive content to ensure that the interactive content is displayed to the users at the predetermined times. The apparatus is useful for providing timely user interaction even via the cellular network. Further refinements include traffic spreading at the application layer, and the use of SMS to provide a user with the URL for initial logging on.

A system and method is provided for use in connection with delivering content that is targeted to users of a broadcast network. In order to select content that is targeted to users of the broadcast network, signals are received from a plurality of customer premise equipment devices (CPEs) of the network users via a broadcast network interface. Based on the received signals, broadcast assets (e.g., programming, advertisements etc.) are selected from a collection of available asset options. Accordingly, at least a portion of the selected assets are inserted into a content stream of the broadcast network. Once the content stream is broadcast over a broadcast network interface, at least a portion of the selected assets area available for receipt by at least a portion of the CPEs. The CPEs generate reports regarding assets delivered such that asset providers can be billed based on guaranteed targeted impressions.

A method of enabling a television viewer to interact with a television programme. A television signal corresponding to said television programme is broadcast by a television corporation 1 whilst an information server 5 is synchronised to the broadcast. Messages are sent from the information server 5 to a mobile wireless terminal 7 operated by the television viewer and/or received messages received at the information server 5 from wireless terminal 7. The sending and/or receipt of messages at the information server 5 is synchronised with the broadcast television signal.

A system, method, apparatus and computer code are provided for producing coherent symbols from digital RF transmitters. A multiplexer receives a digital signal containing content data to be broadcast from the digital RF transmitters and inserts a first initialization packet into the digital signal, where the initialization packets implicit position in the digital signal will signal data framing in the digital RF transmitters. Where the initialization packet contains stuff bytes for deterministically initializing Trellis coders in the digital RF transmitters. A transport stream emitter transmits the digital signal to the plurality of digital RF transmitters.

A media system comprising a broadcast system, a telecommunication system, a content processing system, and a user terminal. While a media stream is broadcast, a group of content items associated with the media stream are generated. The content items are presented in the user terminal in a first mode, wherein a presentation element corresponding to a content item is changed to another presentation element according to the timing information of the content item, or in a second mode wherein a presentation element is changed to another presentation element in response to a user action. Transition from the second mode is allowed only by authorization according to a pre-defined procedure. The interactive operations are thus controlled by the user and thus not overridden by content timed or pushed to the user terminal for display.

A broadcast service for transmission to mobile terminals 10a-10c in a cellular communication system comprises a series of burst B1-B5 of data packets in a transport stream 7. Where the available data transmission rates in cells C1, C2 are unequal, the transport stream 7a for transmission to the cell C1 with the higher data transmission rate is modified by incorporating additional payload L1-L5 in each burst in the series, for example by appending the additional payload to each burst or by interleaving the burst data and additional payload (FIG. 7) so that a time interval t; between adjacent bursts B1-B5 is the same in both cells C1, C2. Therefore, start times of the transmission of each burst B1-B5 in both cells C1, C2 are synchronised, i.e. the transmission of each burst B1-B5 begins simultaneously in both cells C1 or a time interval to between the start of transmission of each burst in cells C1, C2 is fixed (FIG. 5). This allows a mobile terminal 10b operating in a selective data reception mode to continue receiving a service without disruption when moving across a cell boundary 11. The incorporation of the additional payload may be performed by a digital broadcast head-end 26 or by an apparatus 13 associated with a transmitter 8 serving a cell C1.
