Method of displaying contents, method of synchronizing contents, and method and device for displaying broadcast contents

2:

• The method of claim 1, wherein the updating of the structuralized initial scene configuration information comprises one of:
• adding an additional configuration corresponding to the received additional scene configuration information to the structuralized initial scene configuration information,
• replacing a replaceable configuration corresponding to the received additional scene configuration information with a configuration of the structuralized initial scene configuration information, and
• deleting a configuration of the structuralized initial scene configuration information according to the received additional scene configuration information.

4:

• The method of claim 3, wherein the updating of the structuralized initial scene configuration information comprises one of:
• adding a tree node corresponding to the received additional scene configuration information to the DOM tree,
• replacing a replaceable tree node corresponding to the received additional scene configuration information with nodes of the DOM tree, and
• deleting nodes of the DOM tree according to the received additional scene configuration information.

5:

• A method of synchronizing contents, the method comprising:
• receiving a transmission stream through a broadcast network;
• parsing the received transmission stream;
• in response to determining that a first content in the transmission stream is a multiview content according to a parsing result from the parsing, receiving a second content corresponding to the first content through a communication network;
• and
• simultaneously outputting the first content in the transmission stream and the received second content.

7:

• The method of claim 5, wherein the receiving of the second content comprises:
• receiving a media presentation description (MPD) and an initialization segment;
• and
• receiving a segment of the second content corresponding to a frame number of the first content in which a PTS value of the first content is equal to a PTS value of the multiview content.

8:

• The method of claim 5, wherein the receiving the second content comprises:
• receiving an MPD and an initialization segment;
• and
• calculating a current frame number of the first content based on a difference between a PTS value of a current frame of the first content and a PTS starting value;
• and
• receiving a segment of the second content corresponding to the current frame number of the first content.

9:

• The method of claim 5, wherein the receiving of the second content comprises:
• receiving an MPD and an initialization segment;
• and
• calculating time information of the first content based on a difference between an SMPTE timecode value of the first content and an SMPTE timecode starting value and receiving a segment of the second content corresponding to the time information of the first content.

11:

• A method of displaying broadcast contents, the method comprising:
• transmitting scene configuration information of a first content written in a markup language through a first server;
• transmitting and rendering the first content based on the scene configuration information of the transmitted first content;
• and
• in response to a second content viewing event occurring, transmitting and rendering a second content through a second server.

14:

• A display device comprising:
• a receiver configured to receive initial scene configuration information of a content written in a markup language and configured to receive the content from an external device;
• an outputter configured to output the received content;
• and
• a controller configured to parse and structuralize the initial scene configuration information, and render and output the content received from the external device according to the structuralized initial scene configuration information,
• wherein in response to the receiver receiving additional scene configuration information of the content from the external device, the controller is configured to update the structuralized initial scene configuration information based on the received additional scene configuration information, and render and output the content according to the updated initial scene configuration information.
