Abstract:
A reproducing apparatus for reading data from a recording medium on which a management area is provided to include management information, said management information comprises,a first sample data string created by digitizing a first one of channel audio signals, the first sample data string having attributes defined as including at least a first sampling frequency and a first number of quantization bits, a second sample data string created by digitalizing a second one of said channel audio signals, the second sample data string having attributes defined as including at least a second sampling frequency and a second number of quantization bits, header data including timing data to synchronize said first sample data string with said second sample data string, a channel mixing coefficient, and an audio title set information management table, including: a start address of an audio only title video title set, an attribute of an audio only title audio object set, and an attribute of an audio only title video object set, said reproducing apparatus comprising: transfer means for recovering timing data included in said header data, or synchronization data created on the basis of the timing data relative to said first sample data string and said second sample data string, and wherein said transfer means employs the channel mixing coefficient for mixing down said first and second channel audio signals having multi-channel output into two-channel output for transfer from the recording medium to an output of the reproducing apparatus.
