Provided are a method and an apparatus for providing three-dimensional (3D) digital content by using a conventional system for providing two-dimensional (2D) digital content. The method includes generating an elementary stream (ES) regarding first data of 2D digital content, generating an ES regarding second data of 3D digital content, packetizing the ESs of the first data and the second data, and recording) the packetized second data and content information of the second data within header information of multiplexed stream of the packetized first data.

Provided are a method and apparatus for providing and reproducing a three-dimensional (3D) video content, and a computer readable recording medium storing a program to execute the method. The method of providing 3D image content includes: inserting content type information indicating whether the image content is two-dimensional (2D) image content or 3D image content into a reserved region of a Program Map Table (PMT); inserting additional information about the 3D image content into one of an Elementary Stream (ES) descriptor region of the PMT and a reserved region included in a video sequence of the ES; and multiplexing the PMT and the ES of the 3D image content so as to generate a Transport Stream (TS). Accordingly, compatibility with a conventional digital broadcasting system can be maintained and more realistic 3D image content can be provided to a user.

A method of generating a datastream including two-dimensional (2D) video content or three-dimensional (3D) video content includes: inserting video data of the 2D video content or the 3D video content into the datastream; inserting into the datastream recognition information insertion information indicating whether 3D user recognition information including a mark used for a user to recognize that a 3D video is being reproduced is inserted in the datastream and display rights information indicating whether displaying of 3D user recognition information unique to a reproduction device is authorized; and transmitting the datastream.
摘要:
A multimedia stream generating method for 3-dimensional (3D) reproduction of additional reproduction information is provided. The method includes generating a video elementary stream (ES), an audio ES, an additional data stream, and an ancillary information stream that respectively comprise video data, audio data related to the video data, data of additional reproduction information which is to be reproduced together with the video data on a display screen, and additional reproduction information depth information used for 3D reproduction of the additional reproduction information, the video data including at least one of a 2D video image and a 3D video image.

摘要:
A method of receiving media data capable of being transceived via a digital data interface is provided. In the method, media data is received and parsed, and ancillary data for raw data and compression-related information about compressed data for the raw data are extracted from an ancillary data field of the parsed media data. The compressed data is extracted from the parsed media data, and the compressed data is decoded using the compression-related information so as to restore the raw data. The restored raw data is played back using the ancillary data and the compression-related information.
