Abstract

To secure easiness of component selection at a reception side. A transmission stream is generated in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner.

Claims

1. A transmission device, comprising:

a transmission stream generator configured to generate a transmission stream in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner;

a transmitting unit configured to transmit the transmission stream via a predetermined transmission path; and

an information inserting unit configured to insert component selection information into the second transmission packet.

2. The transmission device according to claim 1,

wherein the component selection information includes selective layer information for performing fixed selection, composite layer information for performing composition, and adaptive layer information for performing dynamic switching from the top.

3. The transmission device according to claim 2,

wherein information for acquiring an acquisition destination is included in information of each component that is selectable in the adaptive layer.

4. The transmission device according to claim 1,

wherein the transmission packet is an MMT packet, and

in the second transmission packet including a package access message, a component structure table including the component selection information is arranged in the package access message together with an MMT package table.

5. The transmission device according to claim 4,

wherein a component of the component structure table is associated with an asset of the MMT package table using a component tag.

6. The transmission device according to claim 4,

wherein the component selection information includes selective layer information for performing fixed selection, composite layer information for performing composition, and adaptive layer information for performing dynamic switching from the top, and

the component structure table includes selection information of an integrated component serving as the selective layer information and selection information of an atomic component serving as the composite layer information and the adaptive layer information from the top for each component category.

7. A transmission method, comprising:

a transmission stream generation step of generating a transmission stream in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner;

a transmission stream transmission step of transmitting the transmission stream via a predetermined transmission path by a transmitting unit; and

an information insertion step of inserting component selection information into the second transmission packet.

8. A reception device, comprising:

a first receiving unit configured to receive, via a first transmission path, a transmission stream in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner; and

a second receiving unit configured to receive a transmission stream in which a third transmission packet including a predetermined component is arranged via a second transmission path,

wherein component selection information is inserted into the second transmission packet, and

the reception device further includes a component selecting unit configured to select a component to be presented based on the component selection information.

9. The reception device according to claim 8,

wherein the component selecting unit causes a selection graphic user interface to be displayed on a screen when there is a variation related to a specific attribute to be selected by a user in the component selection information.

10. The reception device according to claim 8,

wherein the component selection information includes selective layer information for performing fixed selection, composite layer information for performing composition, and adaptive layer information for performing dynamic switching from the top.

11. The reception device according to claim 10,

wherein information for acquiring an acquisition destination is included in information of each component that is selectable in the adaptive layer.

12. The reception device according to claim 8,

wherein the first transmission path is a broadcast transmission path, and the second transmission path is a network transmission path.

13. A reception method, comprising:

a first reception step of receiving, by a first receiving unit, a transmission stream in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner; and

a second reception step of receiving, by a second receiving unit, a transmission stream in which a third transmission packet including a predetermined component is arranged via a second transmission path,

wherein component selection information is inserted into the second transmission packet, and

the reception method further includes a component selection step of selecting a component to be presented based on the component selection information.
