Method and apparatus for managing and processing information of an object for multi-source-streaming
Preparing of information about a content source is disclosed. One method in accordance with the information preparing creates item information on a first component pertaining to an arbitrary content source, incorporates the created information on the first component into a first structure element (e.g., tag), creates a second structure element containing information making display layout information for the arbitrary content source accessible, creates information on at least one component pertaining to the arbitrary content source other than the first component, and incorporates the created information on the at least one component into at least one third structure element included within the second structure element.
1. A method for controlling a multiple component including a video content and an audio content, the method comprising:
issuing a browse action to a media server for obtaining additional information, the additional information indicating a metadata associated with the multiple component;
receiving a browse response in response to the browse action, wherein the browse response includes the additional information including a video component, an audio component and a caption component, wherein each of the video component, the audio component and the caption component is grouped based on a component type, and wherein each of the grouped video component, the grouped audio component and the grouped caption component is included in a separate resource structure element;
issuing a play action to a media renderer for requesting a playback of the video content and the audio content;
playing the video content and the audio content according to the play action, wherein the video content and the audio content are synchronously played based on the additional information; and
issuing a transform action to the media renderer for changing the audio content to other audio content during the playing of the video content and the audio content,
wherein the audio content and the other audio content are included in the grouped audio component, and
wherein the grouped audio component further includes access location information and expression language information.
2. The method of claim 1 , wherein each of the grouped video component, the grouped audio component and the grouped caption component comprises information on whether a grouped component is essential for playing the video content.
3. The method of claim 1 , wherein the grouped video component and the grouped audio component comprise coding type information.
4. An apparatus for controlling a multiple component including a video content and an audio content, the apparatus comprising:
a processor configured to:
issue a browse action to a media server for obtaining additional information, the additional information indicating a metadata associated with the multiple component,
receive a browse response in response to the browse action, wherein the browse response includes the additional information including a video component, an audio component and a caption component, wherein each of the video component, the audio component and the caption component is grouped based on a component type, and wherein each of the grouped video component, the grouped audio component and the grouped caption component is included in a separate resource structure element,
issue a play action to a media renderer for requesting a playback of the video content and the audio content, play the video content and the audio content according to the play action, wherein the video content and the audio content are synchronously played based on the additional information, and
issue a transform action to the media renderer for changing the audio content to other audio content during the playing of the video content and the audio content,
wherein the audio content and the other audio content are included in the grouped audio component, and
wherein the grouped audio component further includes access location information and expression language information.
5. The apparatus of claim 4 , wherein each of the grouped video component, the grouped audio component and the grouped caption component comprises information on whether a grouped component is essential for playing the video content.
6. The apparatus of claim 4 , wherein the grouped video component and the grouped audio component comprise coding type information.
