METHODS OF TRANSMITTING AND RECEIVING A MEDIA INFORMATION FILE FOR HTTP STREAMING

摘要

Disclosed are methods of transmitting and receiving a media information file for HTTP stream. Content is divided into a plurality of segments; the plurality of segments are divided into a plurality of segment sub groups, each grouping plural segments; a meta media information file including information on a segment sub group is configured; and a sub media information file including information on a plurality of segments in a segment sub group is configured. When service initializes, the metal media information file is transmitted. When a transmission request for content is received, the sub media information file to which a playback request timing for content belongs is selected and transmitted by referring to the meta media information file, and then, a segment in a segment sub group corresponding to the sub media information file is transmitted. Thus, during HTTP streaming, initial transmission delay is reduced, and random access and trick mode playback are possible.
