摘要:
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 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.
