Patent ID: 8447173

Claim:
An apparatus for reproducing first clip audio/video (AV) stream corresponding to first angle and including a plurality of interleaved units and second clip AV stream corresponding to second angle and including a plurality of the interleaved units from an information storage medium, the plurality of interleaved units in the first clip AV stream being interleaved with the plurality of interleaved units in the second clip AV stream, the apparatus comprising: a reproducing unit configured to reproduce a first interleaved unit among the plurality of interleaved units in the first clip AV stream; and a controller that is configured to reproduce, in response to a request for an angle change to the second angle during the reproduction of the first interleaved unit, a second interleaved unit among the plurality of interleaved units in the second clip AV stream using first clip information which includes information on entry points included in the first clip AV stream and second clip information which includes information on entry points included in the second clip AV stream, wherein the first clip information comprises time information on each of the entry points included in the first clip AV stream, position information on each of the entry points included in the first clip AV stream, and information on whether each of the entry points included in the first clip AV stream is a jumping point, wherein the second clip information comprises time information on each of the entry points included in the second clip AV stream, position information on each of the entry points included in the second clip AV stream, and information on whether each of the entry points included in the second clip AV stream is a jumping point, wherein the first entry point of the first interleaved unit and the first entry point of the second interleaved unit are the jumping points, and wherein the jumping point is an access point through which a motion picture is reproduced from one angle to another angle.
