Abstract:
1. A method for executing AV content in segment units, the method comprising: extracting, by a control point, segment-related information about each of segments, which have a same attribute with each other, among a plurality of segments constituting a single audio/video (AV) content file stored in a first AV device, wherein the extracted segment-related information includes location information about a key frame image of each of the segments, the key frame image being a representative image of a corresponding segment of the segments, and the plurality of segments are stored in the first AV device in segment units and segment-related information about each of the plurality of segments is stored in the first AV device, and wherein each of the plurality of segments includes a plurality of attributes and the same attribute is an attribute selected from the plurality of attributes; fetching, by the control point, key frame images of the segments from the first AV device using the location information included in the extracted segment-related information; and controlling, by the control point, a second AV device to execute the AV content file using the extracted segment-related information in segment units, wherein the controlling the second AV device comprises controlling the second AV device to arrange and display the segments in a time sequence together with the key frame images, wherein the controlling of the second AV device comprises: extracting, by the control point, URI (Uniform Resource Identifier) information of the AV content file, and start position information of the segments to be played back among the plurality of segments constituting the AV content file and transmitting the extracted URI information and the start position information to the second AV device; and executing, by the second AV device, the segments from the AV content file stored in the first AV device using the URI information and the start position information.
