The present technology relates to a receiver for efficiently acquiring a component configuring a service, a reception method, a transmitter, and a transmission method. The receiver acquires first signaling data distributed on a broadcast wave of digital broadcasting in an IP transmission system, acquires broadcast signaling data as second signaling data, acquires communication signaling data as the second signaling data when flag information included in the broadcast signaling data indicates that the communication signaling data is provided from a server over the Internet together with the broadcast signaling data, and connects to a stream of a broadcast component or a stream of a communication component thereby to control reproduction of the component on the basis of at least one of the broadcast signaling data and the communication signaling data. The present technology is applicable to TV receivers, for example.

Media content presentation systems and methods are operable to present media content received by a media device, wherein the media device comprises a plurality of tuner systems. An exemplary embodiment tunes the plurality of tuners to receive different broadcasting media content streams each comprising a streaming media content event; communicates the streaming media content events from the receiving tuner to a corresponding tuner buffer of the tuner system; and stores a portion of the streaming media content events into the corresponding tuner buffers. When a user selection is received for presentation of one of the streaming media content events, the selected one of the streaming media content events are presented to a user of the media device.

A temporal sequence of pictures is generated in a method for encoding of a first video stream. To do so, a synchronization signal can be used, which can be derived from a second video stream independently of the first video stream. Alternatively, the encoding of a second video stream independent of the first video stream can be based on the same principle as for the encoding of the first video stream.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

A reception apparatus including reception circuitry and processing circuitry is provided. The reception circuitry is configured to receive control information and content, the control information including resource sharing information indicating whether a resource is shared among a plurality of applications. The processing circuitry is configured to control, based on the resource sharing information, sharing of the resource among the plurality of applications. The resource sharing information includes an identifier that is associated with the plurality of applications among which the resource is shared. The resource includes at least one file associated with at least one of the plurality of applications.

A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

A reception apparatus receives a content transmitted in an IP transmission system, acquires, based on first control information that is transmitted in a first layer in a protocol stack of the IP transmission system and includes information indicating whether second control information transmitted in a second layer higher than the first layer exists, the second control information, and controls operations of units that process the content based on the second control information.

A control signal transmission circuit and a control signal receiving circuit for an audio/video interface are provided. The control signal transmission circuit includes an audio/video interface encoder, a signal packaging circuit and a data allocator. The audio/video interface encoder is configured to receive an audio packet and supports a user-defined packet format. The signal packaging circuit is configured to receive a first control signal and package the first control signal into a control data packet according to the user-defined packet format. The data allocator is configured to receive a video data and a second control signal and to mix the second control signal and the video data to generate a mixed data packet. The audio/video interface encoder packages the control data packet, the mixed data packet and the audio packet according to an audio/video transmission protocol to generate an audio/video and control data.

A video receiver apparatus, for receiving video from a video transmitter apparatus, comprises: a memory portion for memorizing receiver apparatus information of the video receiver apparatus; and a transmitter/receiver portion for receiving a request for obtaining the receiver apparatus information transmitted from the video transmitter apparatus, and also for transmitting the receiver apparatus information memorized in the memory portion responding to the obtaining request, and wherein, further within the memory portion is memorized history information, changing depending on alternation of the receiver apparatus information, and wherein the receiver portion is able to receive the history information, which the video transmitter apparatus holds therein, as well as, the obtaining request from the video transmitter, and when the received history information from the video transmitter apparatus and the history information, which the video transmitter apparatus holds therein, are inconsistent with each other, then the receiver apparatus information memorized in the memory portion is transmitted to the video transmitter apparatus.
