Abstract

A transmission stream is generated. In the transmission stream, a first transmission packet where transmission media is included in a payload and a second transmission packet where information relating to the transmission media is included in the payload are time division multiplexed. The transmission stream is transmitted to a receiving side through a predetermined transmission path. If the transmission media included in the payload of the first transmission packet is file data configuring the predetermined contents, information relating to the predetermined contents is inserted into a header thereof. At the receiving side, the first transmission packet including the file data configuring the predetermined contents can be acquired easily and accurately based on the information.

Claims

1. A transmitting apparatus, comprising:

circuitry configured to

generate a transmission stream including a first transmission packet where media is included in a payload of the first transmission packet and a second transmission packet where first signaling information including information identifying a content including the media is included in a payload of the second transmission packet, the first transmission packet and the second transmission packet being time division multiplexed;

insert the information identifying the content including the media into a header of the first transmission packet, if the media included in the payload of the first transmission packet is file data configuring the content, such that the information identifying the content included in the first signaling information of the payload of the second transmission packet is the same as the information identifying the content inserted into the header of the first transmission packet; and

transmit the transmission stream, wherein

the first signaling information included in the payload of the second transmission packet is included in an MPEG Media Transport (MMT) Package Table (MPT), which includes a content identification field as the information identifying the content.

2. The transmitting apparatus according to claim 1, wherein the information identifying the content includes a content version showing an update of the file data configuring the content.

3. The transmitting apparatus according to claim 1, wherein the information identifying the content includes information relating to a part number if the content is divided into a predetermined number of packets and a part identifier for identifying each part.

4. The transmitting apparatus according to claim 1, wherein the circuitry is configured to insert second information relating to the content into the payload of the second transmission packet.

5. The transmitting apparatus according to claim 4, wherein the second information includes content version information showing an update of the file data configuring the content.

6. The transmitting apparatus according to claim 4, wherein the second information includes reference information configuring the content.

7. The transmitting apparatus according to claim 6, wherein the reference information is an URI.

8. The transmitting apparatus according to claim 4, wherein the second information includes information relating to an expiration date of the content.

9. The transmitting apparatus according to claim 4, wherein the second information includes estimated update time information of the content.

10. The transmitting apparatus according to claim 1, wherein the first and second transmission packets are MMT packets.

11. A transmission method, comprising:

generating a transmission stream including a first transmission packet where media is included in a payload of the first transmission packet and a second transmission packet where first signaling information including information identifying a content including the media is included in a payload of the second transmission packet, the first transmission packet and the second transmission packet being time division multiplexed;

inserting the information identifying the content including the media into a header of the first transmission packet, if the media included in the payload of the first transmission packet is file data configuring the content, such that the information identifying the content included in the first signaling information of the payload of the second transmission packet is the same as the information identifying the content inserted into the header of the first transmission packet; and

transmitting the transmission stream, wherein

the first signaling information included in the payload of the second transmission packet is included in an MPEG Media Transport (MMT) Package Table (MPT), which includes a content identification field as the first signaling information.

12. A receiving apparatus, comprising:

circuitry configured to

receive a transmission stream, the transmission stream including a first transmission packet where media is included in a payload of the first transmission packet and a second transmission packet where first signaling information including information identifying a content including the media is included in a payload of the second transmission packet, the first transmission packet and the second transmission packet being time division multiplexed, wherein the information identifying the content including the media is inserted into a header of the first transmission packet, if the media included in the payload of the first transmission packet is file data configuring the content, such that the information identifying the content included in the first signaling information of the payload of the second transmission packet is the same as the information identifying the content inserted into the header of the first transmission packet; and

filter the first transmission packet including the file data configuring the content from the transmission stream using the first signaling information, and acquire the file

data configuring the content from the filtered first transmission packet, wherein the first signaling information included in the payload of the second transmission packet is included in an MPEG Media Transport (MMT) Package Table (MPT), which includes a content identification field as the first signaling information.

13. The receiving apparatus according to claim 12, wherein second information relating to the content is inserted into the payload of the second transmission packet, and the circuitry filters the first transmission packet including the first signaling information corresponding to the second information.

14. A reception method, comprising:

receiving a transmission stream, the transmission stream including a first transmission packet where media is included in a payload of the first transmission packet and a second transmission packet where first signaling information including information identifying content including the media is included in a payload of the second transmission packet, the first transmission packet and the second transmission packet being time division multiplexed, wherein the information identifying the content including the media is inserted into a header of the first transmission packet, if the media included in the payload of the first transmission packet is file data configuring the content, such that the information identifying the content included in the first signaling information of the payload of the second transmission packet is the same as the information identifying the content inserted into the header of the first transmission packet; and

filtering the first transmission packet including the file data configuring the content from the transmission stream using the first signaling information, and acquiring the file data configuring the content from the filtered first transmission packet, wherein the first signaling information included in the payload of the second transmission packet is included an MPEG Media Transport (MMT) Package Table (MPT), which includes a content identification field as the first signaling information.
