Processing and transmitting transmission frames. A method for processing a transmission frame, includes receiving a transmission frame including a bootstrap portion, a preamble portion, and a payload portion. The boot strap portion of the received transmission frame is processed, by processing circuitry of a reception apparatus, to extract preamble structure information from one of four bootstrap symbols included in the bootstrap portion. The preamble portion of the transmission frame is decoded, by the processing circuitry, based on the extracted preamble structure information. A first one of the four bootstrap symbols is used for synchronization and a last one of the four bootstrap symbols in the bootstrap portion includes the preamble structure information. Further, the preamble structure information indicates a structure of one or more preamble symbols in the preamble portion that follows the last symbol.

Ancillary information associated with one or more images embedded in a digital broadcast data stream may be accessed by a digital broadcast receiving device. The device may include a receiver unit, a processor, and a memory. The processor may execute program instructions to access the ancillary information. Control data may be associated with one or more visual components of one or more video images. The control data and images may be combined into a digital broadcast data stream. The device may receive the images and control data. The images may be presented on a display device. The receiving device may use the control data to present or store a perceptible indication that ancillary information is associated with the visual components in conjunction with presenting the images. The device may use the control data to present or store the ancillary information in response to an input signal.

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.
