Claim:
An apparatus for reproducing data from a storage medium on which AV data divided into clips is recorded, and additional information regarding jump points is recorded separately from the clips, the apparatus comprising: a reading unit configured to read the AV data from the storage medium; a source de-packetizer configured to remove an arrival time stamp (ATS) from the read AV data and output the AV data from which the ATS is removed; a counter configured to be initialized based on information received from the source de-packetizer and provide arrival time information for the source de-packetizer; and a reproducing unit configured to: reproduce the AV data from which the ATS is removed by the source de-packetizer; and in response to a command to change from an angle to a new angle is received, reproduce a clip for the new angle from a jump point of the clip for the new angle, each clip comprising a plurality of jump points which are access points which enable jumping from the angle to the new angle, AV data with same jump points comprising same presentation time information, wherein the counter is further configured not to be reset based on the information received from the source de-packetizer during the angle change, for seamless reproduction of the AV data.
