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 receiving apparatus in a multimedia system, the method comprising:

controlling, by an electronic device, a transceiver for receiving 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 received 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 received 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.
