Abstract

The present disclosure relates to a method of transmitting multimedia content in a broadcast communication system, and comprises the steps of: identifying protocol information mapped for each service corresponding to multimedia content; transmitting service-related information including the identified protocol information mapped for each service; and transmitting multimedia content corresponding to related services to a receiving side by using the identified protocol.

Claims

1. A method for transmitting media content by a transmitting apparatus in a broadcasting communication system, the method comprising:

identifying a protocol for transmitting signaling information;

generating service-related information comprising bootstrap information for discovery of the signaling information and protocol information indicating a type of the identified protocol, the type of the identified protocol being one of real-time object delivery over unidirectional transport (ROUTE) protocol and moving picture experts group media transport protocol (MMTP);

transmitting the service-related information; and

transmitting the signaling information comprising information for obtaining the media content based on the protocol,

wherein the signaling information is received, by a receiving apparatus, based on the bootstrap information and the protocol information included in the service-related information,

wherein the protocol information comprises a value among a plurality of values, and

wherein each of the plurality of values indicates a different protocol.

2. The method of claim 1, wherein the bootstrap information is determined based on the protocol.

3. The method of claim 1, wherein the method further comprises transmitting the media content as a plurality of units defined according to the protocol by using the protocol.

4. The method of claim 3,

wherein, if the protocol is moving picture experts group media transport protocol (MMTP), each of the plurality of units is a media processing unit (MPU) or a media fragment unit, MFU, and

wherein, if the protocol is real-time object delivery over unidirectional transport (ROUTE), each of the plurality of units is a dynamic adaptive streaming over hypertext transfer protocol, DASH, segment.

5. The method of claim 1, wherein the signaling information is transmitted in internet protocol, IP, packet which comprises IP header, regardless of the protocol.

6. A method for receiving media content by a receiving apparatus in a broadcasting communication system, the method comprising:

receiving service-related information comprising bootstrap information for discovery of signaling information and protocol information indicating a type of a protocol for transmitting the signaling information, the type of the identified protocol being one of real-time object delivery over unidirectional transport (ROUTE) protocol and moving picture experts group media transport protocol (MMTP);

identifying the protocol information included in the service-related information; and

receiving the signaling information comprising information for obtaining the media content based on the bootstrap information and the protocol information included in the service-related information,

wherein the protocol information comprises a value among a plurality of values, and

wherein each of the plurality of values indicates a different protocol.

7. The method of claim 6, wherein the method further comprises receiving the media content divided in a plurality of units defined according to the protocol by using the protocol.

8. The method of claim 7,

wherein, if the protocol is moving picture experts group media transport protocol (MMTP), each of the plurality of units is a media processing unit (MPU) or a media fragment unit, MFU, and

wherein, if the protocol is real-time object delivery over unidirectional transport (ROUTE), each of the plurality of units is a dynamic adaptive streaming over hypertext transfer protocol, DASH, segment.

9. The method of claim 6, wherein the signaling information is transmitted in an internet protocol (IP) packet, which comprises an IP header, regardless of the protocol.

transmit the service-related information, and

transmit the signaling information comprising information for obtaining the media content based on the protocol, and

wherein the signaling information is received, by a receiving apparatus, based on the bootstrap information and the protocol information included in the service-related information,

wherein the protocol information comprises a value among a plurality of values, and

wherein each of the plurality of values indicates a different protocol.

11. The apparatus of claim 10, wherein the bootstrap information is determined based on the protocol.

12. The apparatus of claim 10, wherein the signaling information is transmitted in an internet protocol (IP) packet, which comprises an IP header, regardless of the protocol.

13. An apparatus for receiving media content in a broadcasting communication system, the apparatus comprising:

a transceiver; and

at least one processor connected to the transceiver,

wherein the at least one processor is configured to;
