Abstract

A method of operating a transmitting apparatus in a multimedia system is provided. The method includes transmitting a data unit of a multimedia service including event information related to an event, wherein the event includes notification to an application, the notification indicating that an action is to be taken.

Claims

1. A method of operating a transmitting apparatus in a multimedia system, the method comprising:

controlling, by an electronic device, a transceiver for transmitting event information related to an event,

wherein the event includes notification to an application, the notification indicating that an action is to be taken,

wherein the event information is transmitted in a first event information box included in a media presentation description (MPD) if the event information indicates a first event for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH)-based services, and

wherein the event information is transmitted in a second event information box included in a media processing unit (MPU) in a moving picture experts group media transport (MMT) payload, if the event information indicates a second event for MMT-based services.

2. The method of claim 1, wherein the event information includes at least one of an identifier (ID) of the event, start time of the event, duration of the event, or event data of the event.

3. The method of claim 2, wherein the start time of the event includes difference between time that the MPU is presented and time that the event is applied in the MPU.

4. The method of claim 2, wherein the event data includes the action.

5. A method of operating a transmitting apparatus in a multimedia system, the method comprising:

controlling, by an electronic device, a transceiver for transmitting a message that includes first information indicating presence of a data unit of a multimedia service including event information related to an event,

wherein the event includes notification to an application, the notification indicating that an action is to be taken,

wherein the data unit includes a media presentation description (MPD) and the event information is included in a first event information box included in the MPD if the event information indicates a first event for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH)-based services, and

wherein the data unit includes a media processing unit (MPU) and the event information is included in a second event information box included in the MPU in a moving picture experts group media transport (MMT) payload, if the event information indicates a second event for MMT-based services.

6. The method of claim 5, wherein the message further includes second information indicating that the message includes the first information.

7. The method of claim 5, wherein the event information includes at least one of an identifier (ID) of the event, start time of the event, duration of the event, or event data of the event.

8. The method of claim 7, wherein the start time of the event includes difference between time that the MPU is presented and time that the event is applied in the MPU.

9. The method of claim 7, wherein the event data includes the action.

10. The method of claim 6, wherein the message is an MMT package table (MPT) message, and the first information is asset-level information.

11. A transmitting apparatus in a multimedia system, the transmitting apparatus comprising:

at least on processor

a transceiver configured to receive and transmit a signal; and

at least one memory storing one or more computer programs configured to be executed by the at least one processor, wherein the one or more computer programs include instructions to at least;

control the transceiver to transmit event information related to an event,

wherein the event includes notification to an application, the notification indicating that an action is to be taken,

wherein the event information is transmitted in a first event information box included in a media presentation description (MPD) if the event information indicates a first event for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH)-based services, and

wherein the event information is transmitted in a second event information box included in a media processing unit (MPU) in a moving picture experts group media transport (MMT) payload, if the event information indicates a second event for MMT based services.

12. The transmitting apparatus of claim 11, wherein the event information includes at least one of an identifier (ID) of the event, start time of the event, duration of the event, or event data of the event.

13. The transmitting apparatus of claim 12, wherein the start time of the event includes difference between time that the MPU is presented and time that the event is applied in the MPU.

14. The transmitting apparatus of claim 12, wherein the event data includes the action.
