Abstract

A receiving system and a method of processing data are disclosed herein. The receiving system includes a receiving unit, a system information processor, a decoding unit, and a display unit. The receiving unit receives a broadcast signal including a 3D content and system information associated with the 3D content. The system information processor extracts identification information from the system information. Herein, the identification information may identify that the broadcast signal being received by the receiving unit includes the 3D content. The decoding unit decodes the received 3D content based upon transmission format information of the 3D content. Herein, the transmission format information may be included in the extracted identification information. And, the display unit displays the 3D content decoded by the decoding unit as a 3D image based upon a display method of a display device.

First claim

The invention claimed is:

1. A transmitting system comprising:
a generator configured to generate program elements for a 3-dimensional (3D) content including stereo images or multi-view images, and generate signaling information of the program elements;
a multiplexer configured to multiplex the program elements and the signaling information; and
a transmitter configured to transmit the multiplexed the program elements and the signal information,
wherein the signaling information includes first table information providing a correspondence between a program number and a packet identifier (PID) of transport stream (TS) packets which carries the program elements, and second table information mapping between program numbers and the program elements,
wherein the second table comprises a stream type specifying a type of a video stream carried within the TS packets, an elementary packet identifier specifying an elementary PID of the TS packets which carry the video stream,
wherein the second table information includes a first descriptor,
wherein the first descriptor includes type information indicating by which transmission format the 3D content has been transmitted,
wherein the transmission format includes a single video stream format and a multi video stream format,
wherein the first descriptor further includes at least one information flag which is used to decode a 3D content having a transmission format of the single video stream format,
wherein the second table information includes a second descriptor when the type information indicates the transmission format of the 3D content being multi video stream format, and
wherein the second descriptor includes a view identifier (ID) and reference information indicating identification information of views that has been referred when encoding was performed on an image of the view corresponding to the view ID.

2. The transmitting system of claim 1 , wherein the second descriptor further includes time reference information indicating a sampling time difference between views included in the 3D content.

3. The transmitting system of claim 1 , wherein the first descriptor includes a flipping information flag indicating whether at least one of the left image data and right image data is inversely scanned and encoded.

4. The transmitting system of claim 1 , wherein the first descriptor includes a filtering information flag indicating whether a quincunx filter is used to perform sampling of the 3D content.

5. A method of transmitting data in a transmitting system, the method comprising:
generating program elements for a 3-dimensional (3D) content including stereo images or multi-view images, and generate signaling information of the program elements;
multiplexing the program elements and the signaling information; and
transmitting the multiplexed the program elements and the signal information,
wherein the signaling information includes first table information providing a correspondence between a program number and a packet identifier (PID) of transport stream (TS) packets which carries the program elements, and second table information mapping between program numbers and the program elements,
wherein the second table comprises a stream type specifying a type of a video stream carried within the TS packets, an elementary packet identifier specifying an elementary PID of the TS packets which carry the video stream,
wherein the second table information includes a first descriptor,
wherein the first descriptor includes type information indicating by which transmission format the 3D content has been transmitted,
wherein the transmission format includes a single video stream format and a multi video stream format,
wherein the first descriptor further includes at least one information flag which is used to decode a 3D content having a transmission format of the single video stream format,
wherein the second table information includes a second descriptor when the type information indicates the transmission format of the 3D content being multi video stream format, and
wherein the second descriptor includes a view identifier (ID) and reference information indicating identification information of views that has been referred when encoding was performed on an image of the view corresponding to the view ID.

6. The method of claim 5 , wherein the second descriptor further includes time reference information indicating a sampling time difference between view included in the 3D content.

7. The method of claim 5 , wherein the first descriptor includes a flipping information flag indicating whether at least one of the left image data and right image data is inversely scanned and encoded.

8. The method of claim 5 , wherein the second table further first descriptor includes a filtering information flag indicating whether a quincunx filter is used to perform sampling of the 3D content.
