Abstract

A transmitting side can actively control a display position of an image.

A container in a predetermined format that includes a video stream obtained by coding image data is transmitted. Display position specification information that specifies a display position of the image by the image data is inserted into a layer of the container. For example, the display position specification information is information that specifies a screen of display target. Additionally, for example, the display position specification information is information that specifies a display unit on a screen of display target. For example, information indicative of whether to change a position of the display unit on the screen of display target specified by the display position specification information or not may be inserted into a layer of the video stream.

Claims

1. A transmitting apparatus comprising:

a transmitting unit configured to transmit a container in a predetermined format, the container including a video stream obtained by coding image data; and

an information inserting unit configured to insert display position specification information into a layer of the container, the display position specification information specifying a display position of an image by the image data.

2. The transmitting apparatus according to claim 1, wherein

the display position specification information is information specifying a display target screen.

3. The transmitting apparatus according to claim 1, wherein

the display position specification information is information specifying a display unit on a display target screen.

4. The transmitting apparatus according to claim 3, wherein

information indicative of a display resolution model at the display target screen is added to the display position specification information, display position information at a resolution coordinate specified by the display resolution model also being added to the display position specification information.

5. The transmitting apparatus according to claim 4, wherein

the information inserting unit is configured to further insert, into a layer of the video stream, information indicative of whether to change a position of a display unit on the display target screen specified by the display position specification information or not and, if the information indicates a change, display position information of the display unit.

6. The transmitting apparatus according to claim 1, wherein

information indicative of whether to permit a display at a display position other than a display position specified by the display position specification information or not is added to the display position specification information.

7. The transmitting apparatus according to claim 1, wherein

the container transmitted by the transmitting unit further includes a subtitle stream obtained by coding subtitle data, and

the information inserting unit is configured to further insert display position specification information into the layer of the container, the display position specification information specifying a display position of a subtitle by the subtitle data.

8. The transmitting apparatus according to claim 1, wherein

a container transmitted by the transmitting unit further includes electronic program guide information, and

the information inserting unit is configured to further insert display position specification information into the layer of the container, the display position specification information specifying a display position of a program guide by the electronic program guide information.

9. The transmitting apparatus according to claim 1, wherein

the container is a transport stream, and

the information inserting unit is configured to insert the display position specification information into a descriptor under a video elementary loop of a program map table included in the transport stream.

10. A transmitting method comprising:

a step of transmitting a container in a predetermined format, the container including a video stream obtained by coding image data; and

a step of inserting display position specification information into a layer of the container, the display position specification information specifying a display position of an image by the image data.

11. A receiving apparatus comprising:

a receiving unit configured to receive a container in a predetermined format, the container including a video stream obtained by coding image data, wherein

display position specification information specifying a display position of an image by the image data is inserted into a layer of the container, and

the receiving apparatus further includes a display control unit configured to control a process of the video stream to display the image by the image data at a display position specified by the display position specification information.

12. The receiving apparatus according to claim 11 further comprising:

a decoding unit configured to decode the video stream to obtain non-compressed image data; and

a transmitting unit configured to transmit the non-compressed image data to a display apparatus by a control by the display control unit, the display apparatus having a display target screen specified by the display position specification information, wherein

the transmitting unit is configured to insert a time code into header information at each frame of the non-compressed image data, the time code being configured to perform counting in units of frames.

13. The receiving apparatus according to claim 11, further comprising:

a transmitting unit configured to transmit the container to a display apparatus by a control by the display control unit, the display apparatus having a display target screen specified by the display position specification information.

14. A receiving method comprising:

a step of receiving a container in a predetermined format, the container including a video stream obtained by coding image data, wherein

display position specification information specifying a display position of an image by the image data is inserted into a layer of the container, and

the receiving method further includes a step of controlling a process of the video stream to display the image by the image data at a display position specified by the display position specification information.

15. A receiving display method comprising:

receiving a container in a predetermined format, the container including a video stream obtained by coding image data, wherein

display position specification information specifying a display position of an image by the image data is inserted into a layer of the container, and

the receiving display method arranges the image by the image data at;

a display position specified by the display position specification information, or a display position different from the display position specified by the display position specification information, by determination based on determination information including at least the display position specification information.

16. The receiving display method according to claim 15, wherein

the determination information further includes display position change information by a user operation.

17. The receiving display method according to claim 16, wherein

information indicative of whether to permit a display at a display position other than a display position specified by the display position specification information or not is added to the display position specification information, and

the determination information further includes the additional information.
