Abstract

A method for sending media information by a first terminal in a multimedia communication system is provided. The method includes generating scene configuration information that includes information regarding at least one medium of multiple media, and sending the scene configuration information to a second terminal, wherein the information regarding the at least one medium includes at least one of information indicating whether to allow reproduction of the at least one medium in the second terminal, resource information used to reproduce the at least one medium, position information used to reproduce the at least one medium on a screen, and reproduction time information for the at least one medium.

Claims

1. A method for performing a multi-screen presentation by a primary device in a multimedia communication system, the method comprising:

obtaining composition information (CI) including a view element; and

presenting a view including one or more areas on a primary screen of the primary device based on spatial and temporal information provided by information for each of the one or more areas in the view element, each of the one or more areas representing a spatial region related to one or more media elements,

wherein a first area of the one or more areas is shown at both the primary screen and a secondary screen of a secondary device, if a first attribute included in information for the first area in the view element includes a first value indicating that the first area is allowed to be used for the multi-screen presentation and to be shown at both the primary screen and the secondary screen, and

wherein the first area is shown at the primary screen, if the first attribute includes a second value indicating that the first area is not allowed to be used for the multi-screen presentation.

2. The method of claim 1, wherein the CI includes list information including a list of media elements.

3. The method of claim 2, wherein the list information includes an attribute indicating an address related to each of the media elements.

4. The method of claim 1, wherein a second area different from the one or more areas is shown at the secondary screen, if a second attribute included in information for the second area in the view element includes a third value indicating that the second area is allowed to be used for the multi-screen presentation and to be shown at the secondary screen.

5. The method of claim 1,

wherein a second area different from the one or more areas is shown at the secondary screen, if a third attribute included in information for the second area in the view element includes a fourth value indicating that the second area is allowed to be used for the multi-screen presentation and to be shown at the secondary screen, and

wherein the second area is not shown at the primary screen before the beginning of the multi-screen presentation based on the fourth value.
