Abstract
There is provided a transmission device including circuitry configured to generate a physical layer frame. A time information descriptor is included in a preamble of the physical layer frame. The time information descriptor includes a time information flag that indicates presence or absence of time information in the time information descriptor. The circuitry is configured to transmit the physical layer frame including the preamble and a payload. The time information indicates a time of a predetermined position in a stream of the physical layer frame.
Claims18
A transmission device, comprising:
- circuitry configured to
- generate a physical layer frame, a time information descriptor is included in a preamble of the physical layer frame, the time information descriptor including a time information flag that indicates presence or absence of time information in the time information descriptor;
- and
- transmit the physical layer frame including a bootstrap, the preamble, and a payload, wherein
- the time information indicates a time at a head of the bootstrap, which is adjacent to the preamble in a stream of the physical layer frame, the time being kept by a predetermined standard.
A method of a transmission device for transmitting a physical layer frame, the method comprising:
- generating, by circuitry of the transmission device, the physical layer frame, a time information descriptor is included in a preamble of the physical layer frame, the time information descriptor including a time information flag that indicates presence or absence of time information in the time information descriptor;
- and
- transmitting, by the circuitry, the physical layer frame including a bootstrap, the preamble, and a payload, wherein
- the time information indicates a time at a head of the bootstrap, which is adjacent to the preamble in a stream of the physical layer frame, the time being kept by a predetermined standard.
A reception device comprising:
- circuitry configured to
- receive a physical layer frame, a time information descriptor is included in a preamble of the physical layer frame, the time information descriptor including a time information flag that indicates presence or absence of time information in the time information descriptor;
- and
- perform a process based on the time information when the time information is included in the time information descriptor, wherein
- the time information indicates a time at a head of a bootstrap, which is adjacent to the preamble in a stream of the physical layer frame including the bootstrap, the preamble, and a payload, the time being kept by a predetermined standard.
A method of a reception device for receiving a physical layer frame, the method comprising:
- receiving, by circuitry of the reception device, the physical layer frame, a time information descriptor is included in a preamble of the physical layer frame, the time information descriptor including a time information flag that indicates presence or absence of time information in the time information descriptor;
- and
- performing a process based on the time information when the time information is included in the time information descriptor, wherein
- the time information indicates a time at a head of a bootstrap, which is adjacent to the preamble in a stream of the physical layer frame including the bootstrap, the preamble, and a payload, the time being kept by a predetermined standard.
