Abstract: Clock synchronization and presentation synchronization are appropriately achieved in the case where transmission is performed by carrying, on a broadcast signal, a transmission media packet obtained by fragmenting transmission media such as video and audio.A clock of 27 MHz synchronized with time information acquired from a time information server is generated. Time information including frequency information of the clock of 27 MHz and synchronized with the time information acquired from the time information server is generated. A transmission medium is encoded. The encoded transmission medium is fragmented in a predetermined unit, and a transmission media packet including each fragment is generated. A stream that includes, on time division basis, the transmission media packet, a packet including the time information, and a packet having a control signal is carried on a broadcast wave and transmitted.

Abstract: The present technology relates to a transmission device and a transmission method, each of which enables to efficiently transfer time information. A physical-layer frame is generated on the basis of an FEC frame obtained from input data. A transmission device that transmits a physical-layer frame includes, in a top area of the physical-layer frame, time information indicating the time of a starting position of the top area, which enables to efficiently transfer the time information. The present technology can be applied to, for example, data transfer corresponding to a predetermined broadcasting method.

Abstract: Emergency alert information is suitably transmitted by utilizing a broadcast service. A preamble section 31 of a transmission frame having a 100 ms interval includes a tuning data section 31A and a reserved bit section 31B, and is made up of a designated total bit length. The tuning data section 31A stores L1 data for tuning to a relevant broadcast channel on the receiving side. Also, the reserved bit section 31B inside the preamble section 31 stores emergency alert information processed by an emergency alert information processing unit 202. In a predetermined message mode, emergency alert information having a predefined message is expressed in a binary format and transmitted in just one frame.

Abstract: Achieving an imaging apparatus capable of performing both photographing of visible light and photographing of invisible light with a normal solid-state imaging element used for visible light photographing. An imaging apparatus including: a solid-state imaging element having a plurality of pixels two-dimensionally arrayed on an imaging surface; a light shielding unit that shields an invisible light imaging region of the solid-state imaging element in a space above the imaging surface of the solid-state imaging element; a first optical system that allows light corresponding to visible light contained in external light to be incident on the visible light imaging region of the solid-state imaging element; and a second optical system that allows light corresponding to invisible light contained in external light to be incident on an invisible light imaging region covered by the light shielding unit.

Abstract: The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method which can use binary format signaling data and text format signaling data in combination. There is provided a reception apparatus including a first acquisition unit which acquires, preceding text format second signaling data to be transmitted in a lower-level layer than an IP layer in a hierarchy of a protocol of an IP transmission system and containing control information independent of a service identified by an IP address, binary format first signaling data containing a flag indicating whether the second signaling data exists in digital broadcast using the IP transmission system, a second acquisition unit which acquires the second signaling data on the basis of the first signaling data, and a control unit which controls operation of the units which perform various types of processing on the basis of the second signaling data. The present technology can be applied to, for example, a television receiver.

Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that can improve transmission efficiency. An encoded signal is generated based on realtime data indicated by a waveform L using a predetermined fixed bit rate as a maximum code amount Sx and the encoded signal into which non-realtime data with an insufficient code amount is inserted is transmitted at the fixed bit rate, as indicated by a range Z12, when a code amount of the generated encoded signal is insufficient for the maximum code amount Sx. The present technology can be applied to broadcasting communication.
