Abstract

A method of generating a 3-dimensional (3D) image datastream is provided. The method includes generating an elementary stream including an encoded bit string of 3D image data; generating at least one packetized elementary stream by packetizing the elementary stream; generating at least one section including service related information of the 3D image data; inserting 3D image reproduction information for reproducing the 3D image data into a program guide information section from among the at least one section; generating at least one transport stream packet for each of the at least one section and the at least one packetized elementary stream; and generating a transport stream by multiplexing the at least one transport stream packet.

Claims

1. A method of receiving a video service, the method comprising:

receiving a transport stream comprising at least one of a 2-dimensional (2D) video service and a 3-dimensional (3D) video service;

extracting identification information indicating whether the video service is the 2D video service or the 3D video service based on a first descriptor in PSIP (Program and System Information Protocol) information extracted from the transport stream;

extracting 3D format information indicating a format in which main-view video data and additional-view video data compose the 3D video service, from a second descriptor in the PSIP information; and

displaying the 3D video service by using the main-view video data and the additional-view video data decoded respectively from the transport stream, based on the 3D format information,

wherein the PSIP information comprises an Event Information Table (EIT), and

wherein the identification information is extracted from the EIT for each event unit of the video service.

2. The method of claim 1, wherein the 3D format information indicates which one among a side-by-side format, a top-and-bottom format and a full-picture format the 3D video service is provided in.

3. The method of claim 1, wherein the displaying of the 3D video service comprises:

reconstructing a first elementary stream and a second elementary stream from the transport stream;

decoding the main-view video data extracted from the first elementary stream by using a first decoder; and

decoding the additional-view video data extracted from the second elementary stream by using a second decoder.

4. A method of transmitting a transport stream for providing a video service, the method comprising:

generating a first elementary stream comprising main-view video data of 3D video service;

generating a second elementary stream comprising additional-view video data of the 3D video service;

inserting identification information indicating whether the video service is the 2D video service or the 3D video service, into a first descriptor of Program and System Information Protocol (PSIP); and

inserting 3D format information indicating a format in which main-view video data and additional-view video data compose the 3D video service, into a second descriptor of the PSIP; and

transmitting the transport stream generated by multiplexing the first elementary stream, the second elementary stream and the PSIP,

wherein the PSIP information comprises an Event Information Table (EIT), and

wherein the identification information is inserted into the EIT for each event unit of the video service.

5. The method of claim 4, wherein the 3D format information indicating which one of a side-by-side format, a top-and-bottom format and a full-picture format the 3D video service is provided in.

6. The method of claim 4,

wherein the generating of the first elementary stream comprises encoding the main-view video data by using a first encoder;

and

wherein the generating of the second elementary stream comprises encoding the additional-view video data encoded by using a second encoder.
