Abstract
It is an object of the present invention to provide a method of reproducing stream data according to which the order of reading stream data such as sound data can be controlled. The sound data reproducing processing is implemented by the reading processing portion 200 and the output processing portion 210. The reading processing portion 200 sequentially reads the sound data stored in a CD/DVD 220 to the buffer 161 according to the branch definition file stored in the CD/DVD 220, while the output processing portion 210 sequentially transfers the sound data read out to the buffer 161 to the sound reproducing processor (SPU) 140.
Claims12
A stream data reproducing apparatus for reading out stream data stored in a recording medium and reproducing the data, comprising:
- a reading processing portion for reading out the stream data from the recording medium according to branch definition information stored in the recording medium;
- and
- a processing portion for reproducing the read out stream data.
A method of reproducing stream data according to which stream data stored in a recording medium is read out and reproduced, comprising the steps of:
- reading out branch definition information from the recording medium;
- reading out the stream data from the recording medium according to the branch definition information;
- and
- reproducing the read out stream data.
A recording medium recorded with a stream data reproducing program, the program enabling a processing comprising the steps of:
- reading out branch definition information from the recording medium;
- reading out the stream data from the recording medium according to the branch definition information;
- and
- reproducing the read out stream data.
A stream data reproducing program enabling a processing comprising the steps of:
- reading out branch definition information from the recording medium;
- reading out stream data from the recording medium according to the branch definition information;
- and
- reproducing the read out stream data.
A recording medium recorded with:
- stream data;
- branch definition information to control the order of reading the stream data;
- and
- a stream data reproducing program to allow the stream data to be read out according to the branch definition information and reproduced.
