Abstract
The present invention relates to a method for recording a data stream having a multiple reproduction paths on a high-density optical disk. The present method ensures seamless presentation of video and audio data of a multi-path data stream by setting no-jumping sections to prohibit re-jump after jump. The no-jumping section whose total bit rate is not less than a minimum bit rate is able to remove possible buffer underrun even when the reproduction path is changed during reproduction.
Claims16
A method for recording a data stream having multiple reproduction paths on a recording medium, comprising:
- checking whether total bit rate (TBR) of a data stream section pertaining to one path among multiple reproduction paths is lower than a minimum bit rate and, if lower, assigning an additional bit rate to the data stream section such that the TBR of the data stream section is not lower than said minimum bit rate;
- and
- recording a multi-path data stream including the data stream section on a recording medium.
A recording medium including a data stream having multiple reproduction paths recorded thereon, wherein:
- total bit rate (TBR) of an arbitrary data stream section of one path among multiple reproduction paths is not lower than a minimum bit rate that is set to a value enough to prevent buffer underrun during changes in reproduction path.
