Reception apparatus, reception method, transmission apparatus, and transmission method
View Patent ↗The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method and more particularly to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which bearers transmitted by a plurality of transmission systems are selected appropriately. The reception apparatus acquires control information including information for acquiring data transmitted through a session in a first transmission system at a first layer in a protocol stack of an IP (Internet Protocol) transmission system and for identifying a bearer that transmits the data in a second transmission system at a second layer lower than the first layer; and controls an operation of each unit that acquires the data transmitted on the bearer on the basis of the control information. The present technology is applicable to a television receiver corresponding to ATSC3.0, for example.

select one of the bearers identified in the received control information; and
acquire the transport data from the bearer data transmitted on the selected bearer.
2. The reception apparatus according to claim 1 , wherein
the bearer information includes a bearer identifier for identifying a particular one of the bearers.
3. The reception apparatus according to claim 1 , wherein
the control information includes an IP address and a port number for identifying the ROUTE data transport session.

the bearer protocols include an ATSC (Advanced Television Systems Committee) 3.0 protocol or a 3GPP-MBMS (Third Generation Partnership Project-Multimedia Broadcast Multicast Service) protocol.
7. A reception method for a reception apparatus, the method comprising:
receiving control information regarding acquiring transport data transmitted through a ROUTE (Real-time Object Delivery over Unidirectional Transport) data transport session using a ROUTE protocol, the control information including bearer information identifying bearers that each transmits the transport data for the ROUTE data transport session by transmitting bearer data according to respective bearer protocols;
selecting, by circuitry of the reception apparatus, one of the bearers identified in the received control information; and
acquiring, by the circuitry of the reception apparatus, the transport data from the bearer data transmitted on the selected bearer.
8. The reception method according to claim 7 , wherein
the bearer protocols include an ATSC (Advanced Television Systems Committee) 3.0 protocol or a 3GPP-MBMS (Third Generation Partnership Project-Multimedia Broadcast Multicast Service) protocol.
9. The reception method according to claim 7 , wherein
the ROUTE data transport session includes one or a plurality of LCT (Layered Coding Transport) sessions, and
the control information includes an LSID (LCT Session Instance Description).
10. A transmission apparatus, comprising:
circuitry configured to:
generate control information regarding transmitting transport data transmitted through a ROUTE (Real-time Object Delivery over Unidirectional Transport) data transport session using a ROUTE protocol, the control information including bearer information identifying bearers that each transmits the transport data for the ROUTE data transport session by transmitting bearer data according to respective bearer protocols; and
output the control information and the transport data for transmission on the bearers identified in the control information.
11. The transmission apparatus according to claim 10 , wherein the bearer information includes a bearer identifier for identifying a particular one of the bearers.
12. The transmission apparatus according to claim 10 , wherein the control information includes an IP address and a port number for identifying the ROUTE data transport session.
13. The transmission apparatus according to claim 10 , wherein the ROUTE data transport session includes one or a plurality of LCT (Layered Coding Transport) sessions, and the control information includes an LSID (LCT Session Instance Description).
14. The transmission apparatus according to claim 10 , wherein the bearer protocols includes an ATSC (Advanced Television Systems Committee) 3.0 protocol and a 3GPP-MBMS (Third Generation Partnership Project-Multimedia Broadcast Multicast Service) protocol, the bearer information includes a first bearer identifier identifying an ATSC 3.0 bearer that uses the ATSC 3.0 protocol and a second bearer identifier identifying a 3GPP-MBMS bearer that uses the 3GPP-MBMS protocol, the first bearer identifier includes a first identifier that includes a first part corresponding to an area reachable by a broadcast wave and a second part corresponding to a frequency band assigned to the broadcast wave, and a second identifier identifying a physical pipe, the physical pipe being one of a plurality of physical pipes obtained by dividing the frequency band identified by the first identifier, and the second identifier includes a TMGI (Temporary Mobile Group Identity) identifier.
