Abstract
The present technology relates to a receiving device, a transmitting device, and a data processing method, in which seamless reproduction can be performed at the time of switching a broadcast signal. A receiving device receives a plurality of broadcast signals, and selects a broadcast signal of a target from the plurality of broadcast signals, on the basis of a result of processing with respect to the broadcast signal, and thus, it is possible to perform seamless reproduction at the time of switching the broadcast signal. The present technology, for example, can be applied to a receiver which is capable of receiving digital television broadcast.
Claims11
A receiving device, comprising:
- receiving circuitry configured to receive a physical layer frame including a plurality of broadcast signals each including video boundary information which is information (i) indicating a boundary of a video of a same or corresponding contents and (ii) processed on a physical layer, the plurality of broadcast signals being transmitted in accordance with a time division multiplexing scheme, the video boundary information being included in a header of a baseband packet included in the physical layer after the baseband packet is demodulated;
- and
- processing circuitry configured to (i) select a broadcast signal of a target from the plurality of broadcast signals on the basis of a result of processing with respect to the broadcast signal, and (ii) switch the broadcast signal of the target on the basis of the video boundary information processed on the physical layer.
A data processing method of a receiving device, the method comprising:
- receiving, by receiving circuitry of the receiving device, a physical layer frame including a plurality of broadcast signals each including video boundary information which is information (i) indicating a boundary of a video of a same or corresponding contents and (ii) processed on a physical layer, the plurality of broadcast signals being transmitted in accordance with a time division multiplexing scheme, the video boundary information being included in a header of a baseband packet included in the physical layer after the baseband packet is demodulated;
- selecting, by processing circuitry of the receiving device, a broadcast signal of a target from the plurality of broadcast signals, on the basis of a result of processing with respect to the broadcast signal;
- and
- switching, by the processing circuitry of the receiving device, the broadcast signal of the target on the basis of the video boundary information processed on the physical layer.
A transmitting device, comprising:
- processing circuitry configured to generate video boundary information which is information (i) indicating a boundary of a video of a same or corresponding contents and (ii) processed on a physical layer;
- and
- transmission circuitry configured to, for transmitting the contents, transmit a physical layer frame including a plurality of broadcast signals each including the video boundary information, the plurality of broadcast signals being transmitted in accordance with a time division multiplexing scheme, the video boundary information being included in a header of a baseband packet included in the physical layer after the baseband packet is demodulated.
A data processing method of a transmitting device, the method comprising the steps of:
- generating, by processing circuitry of the transmitting device, video boundary information which is information (i) indicating a boundary of a video of a same or corresponding contents and (ii) processed on a physical layer;
- and
- transmitting the contents in a physical layer frame including a plurality of broadcast signals each including the video boundary information, the plurality of broadcast signals being transmitted in accordance with a time division multiplexing scheme, the video boundary information being included in a header of a baseband packet included in the physical layer after the baseband packet is demodulated.
