Abstract

The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and at reception method that enable a plurality of transport protocols to coexist.
The transmission apparatus generates transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard, and transmits, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information. The present technology is applicable to, for example, IP packet broadcasting.

First claim

The invention claimed is:

1. A transmission apparatus, comprising:
circuitry configured to
generate transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard; and
transmit, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information, wherein

the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport), and
the transport protocol selection information is included in a table as LLS (Low Layer Signaling) information.

2. The transmission apparatus according to claim 1 , wherein the predetermined standard is ATSC (Advanced Television Systems Committee) 3.0.

3. A transmission method for a transmission apparatus, comprising:
generating, using circuitry, transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard; and
transmitting, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information, wherein
the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport), and
the transport protocol selection information is included in a table as LLS (Low Layer Signaling) information.

4. A reception apparatus, comprising:
circuitry configured to
receive, together with transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard, a content provided by the specific service that is transmitted according to the transport protocol set in the transport protocol selection information; and
carry out processing of reproducing the content according to the transport protocol set in the transport protocol selection information, wherein

the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport), and
the transport protocol selection information is included in a table as LLS (Low Layer Signaling) information.

5. The reception apparatus according to claim 4 , wherein
the predetermined standard is ATSC 3.0, and
the plurality of transport protocols are ROUTE and MMT.

6. A reception method for a reception apparatus, comprising:
receiving, together with transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard, a content provided by the specific service that is transmitted according to the transport protocol set in the transport protocol selection information; and
carrying out, using circuitry, processing of reproducing the content according to the transport protocol set in the transport protocol selection information, wherein
the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport), and
the transport protocol selection information is included in a table as LLS (Low Layer Signaling) information.
