摘要: This technology relates to a transmission apparatus, a reception apparatus, and a data processing method for easily implementing circuits on the receiving side.
There is provided a transmission apparatus including a processing section configured to process a stream with respect to each of multiple PLPs included in a broadcast signal, the stream being constituted by packets, the processing section further causing a header of each of the packets to include mapping information mapped to identification information identifying the PLP to which each of the packets belongs. This technology may be applied to data transmission methods such as the IP transmission method or the MPEG2-TS method, for example.-

摘要: A reception apparatus includes a demodulation circuit configured to demodulate packets obtained with respect to each of multiple PLPs included in a broadcast signal; and a processing circuit configured to process the packets demodulated by the demodulation circuit. The demodulation circuit and the processing circuit are connected with each other via a single interface or interfaces fewer than the number of the PLPs. The demodulation circuit adds identification information to a specific packet among the packets obtained with respect to each of the PLP, the identification information identifying the PLP to which each of the packets belongs. The processing circuit identifies the PLP to which belongs each of the packets input from the demodulation circuit via the single interface or the interfaces fewer than the number of the PLPs, based on the identification information obtained from the specific packet.

摘要: To provide a demodulation circuit, a processing circuit, a processing method, and a processing device that are capable of implementing more prompt acquisition of alert information. Provided is a demodulation circuit including a demodulation unit configured to demodulate a broadcast signal received by a reception circuit that receives the broadcast signal, a determination unit configured to determine whether or not acquisition of alert information included in the demodulated broadcast signal is necessary according to a set operation mode, on the basis of first alert notification information indicating an update state of the alert information included in the demodulated broadcast signal, and an output processing unit configured to output second alert notification information corresponding to the operation mode from a predetermined terminal to which a processing circuit having a function to acquire the alert information is electrically connected, in a case where acquisition of the alert information is determined to be necessary.

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.
