Media file format based on, method and apparatus for reproducing the same, and apparatus for generating the same

摘要

A media file format based on an ISO base media file, a method and apparatus for reproducing the same, and an apparatus for generating the same are disclosed. The media file format based on an ISO base media file includes: a first area including first information indicating whether or not a file includes stereoscopic contents; and a second area including second information related to a reproducing method or a storing method of a stream included in the stereoscopic contents. Accordingly, the media file format based on an ISO base media file can effectively store and reproduce stereoscopic contents.

主权项

1. A method for reproducing a media file based on an ISO base media file, the method comprising:
determining whether or not an inputted media file includes identifiable stereoscopic contents based on first information indicating type of stereoscopic contents; when the inputted media file includes the identifiable stereoscope contents, determining the number of streams provided in the stereoscopic contents; when the stereoscopic contents includes two streams, decoding the two streams in the stereoscopic contents based on a first media file including the two streams, and when the stereoscopic contents includes one stream, decoding the stream in the stereoscopic contents based on a second media file including the one stream, wherein the first media file includes a file type box including the first information indicating the type of stereoscopic contents, a movie box including a first video track box corresponding to a first stream of the stereoscopic contents and a second video track box corresponding to a second stream of the stereoscopic contents, and a media data box including the first stream and the second stream, wherein the first and second video track boxes include a media box, respectively, each media box of the first and second video track boxes includes a media information box, and each media information box of the first and second video track boxes includes second information indicating the composition type of the stereoscopic contents, wherein the first media file further includes a meta box including camera information or display-associated information of the stereoscopic contents, and the meta box further includes an XML (eXtensible Markup Language) document, which includes information of depth-map identification, video track identification, the number of bits per pixel of the depth map, quantization level, offset in depth, start of time, and end of time regarding the depth map stream, and wherein the quantization level value and the offset in depth value are proportional to a length of a display.
