Stream transmission using MPEG media transport (MMT)

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.

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.

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.
