摘要： The present technology relates to a data processing apparatus and a data processing method capable of achieving higher convenience in a case where a plurality of transmission formats is available in a transmission frame. The data processing apparatus installed in a transmission-side facility processes a transmission frame transmitted as a broadcast signal and adds identification information for identifying the transmission format of the transmission frame, while a data processing apparatus installed in a reception-side facility processes a transmission frame in which a transmission frame has been identified, on the basis of identification information added to the transmission frame transmitted as the broadcast signal. The present technology can be applied as a method of a test stream, for example.

摘要： The present disclosure relates to a reception apparatus, a reception method, and a program for generating a time stamp with a simple circuit structure that is realized at low cost. In one example, a reception apparatus includes a reception unit, an obtaining unit, a time stamp increment value specifying unit, a time stamp calculating unit and a time stamp adding unit. The reception unit receives a data stream formed of a series of packets. The obtaining unit obtains a transmission parameter from the received data stream. The time stamp increment value specifying unit specifies a time stamp increment value corresponding to the obtained transmission parameter. The time stamp calculating unit updates the time stamp by adding the specified time stamp increment value to a previous time stamp, and the time stamp adding unit adds the updated time stamp to the packets configuring the data stream.

摘要： Information processing with flexibility in interpretation of a standard is disclosed. In one example, an output unit adds additional information related to the BB packet to output the BB packet to a baseband (BB) packet after an error correction decoding process. The additional information includes at least one of a delimiter, a precision time protocol (PTP), or BB packet information. The BB packet information includes at least one of information indicating whether or not reception of the BB packet is stable, information indicating whether or not there is an error in the BB packet, a packet length of the BB packet, a relative physical layer pipe (PLP) ID of the BB packet, or an absolute PLPID of the BB packet.

摘要： Channel bonding is realized in a receiving apparatus that receives terrestrial digital broadcasting compliant with an ATSC 3.0 Standard. A receiving section selects any one of a plurality of frequency channels as a bonding source channel and receives a frame from the bonding source channel. A control section performs processing for obtaining one frequency channel in which packets are to be bonded with the bonding source channel among the plurality of frequency channel as a bonding destination channel on the basis of the frame and processing for controlling the receiving section to newly receive a frame from the bonding destination channel. A decoding section decodes the frame and acquires the packets. A bonding section bonds together the packets corresponding to the bonding source channel and the packets corresponding to the bonding destination channel.

The transmission device generates and transmits an OFDM signal in which additional information of a physical layer is allocated to additional carriers in each of groups, the groups being obtained by grouping the additional carriers to be used for transmission of the additional information, of carriers of the OFDM signal of one frame, into the groups of the number of groups according to a DFT size of when IDFT of the OFDM signal is performed. The reception device receives the OFDM signal, and acquires the additional information corresponding to the number of groups according to the DFT size from the OFDM signal. The present technology can be applied to, for example, transmission and reception of the OFDM signal.-

A demodulation device includes a demodulation unit configured to demodulate a first transmission packet obtained from a broadcast signal, and an output unit configured to output a divided packet via a predetermined interface, the divided packet being obtained by dividing the first transmission packet that is a variable-length packet used in a first transmission method into a packet length according to a second transmission packet that is a fixed-length packet used in a second transmission method and arranging the first transmission packet in a payload, and adding a header including information for restoring the first transmission packet to the payload. The present technology can be applied to, for example, a demodulation IC incorporated in a television receiver or a set top box.
