Abstract
The present invention relates to method and apparatus for reproducing a data stream having a multiple reproduction paths recorded on a high-density optical disk. The present method ensures seamless reproduction of video and audio data of a multi-path data stream by removing possible buffer underrun even when the reproduction path is changed during reproduction.
Claims17
A method for reproducing a multi-path data stream recorded on a recording medium, comprising the steps of:
- (a) reproducing the multi-path data stream;
- (b) responsive to a request for a path change, checking if the size of buffered data stream of a current path being reproduced exceeds a preset reference;
- and
- (c) delaying jumping operation to a data stream of a target path specified by the request based on the result of said checking step (b).
A method for reproducing a multi-path data stream recorded on a recording medium, comprising the steps of:
- (a) reproducing the multi-path data stream;
- (b) responsive to a request for a path change, checking if an entry point pointing to a data stream interval of a current path being reproduced falls within a range of no jumping blocks;
- and
- (c) delaying jumping operation to a data stream of a target path specified by the request based on the result of said checking step (b).
An apparatus for reproducing a multi-path data stream recorded on a recording medium, comprising:
- a driver for driving an optical reproducing device to reproduce a data stream of a selected path among the multi-path data stream recorded on the recording medium;
- storing means for buffering the reproduced data stream of the selected path;
- and
- a controller for checking, responsive to a request for a path change, if the size of the data stream of the selected path buffered in the storing means is larger than a preset reference and for delaying jumping operation to a data stream of a target path specified by the path change request based on the checking result.
