Abstract

In a reproducing apparatus for reproducing audio data, a central control section includes detection means for detecting playlists of plural kinds of formats, and detection means for detecting audio data not associated with playlists. The central control section reads out audio data from an audio data storage section, and discriminating the format of the audio data to detect playlists. In addition, the central control section detects the presence/absence of audio data not associated with playlists, and if audio data not associated with playlists is stored, processes a list of such audio data as one playlist. The central control section causes the detected playlists to be displayed on a display section, successively processes the audio data from a first one of the playlists, and outputs the processed data through a sound output section.

Claims

1. A reproducing apparatus comprising:

playlist detection means for reading out digital data on plural kinds of formats compressed and stored in a memory medium and detecting a plurality of playlists of the read-out digital data; and

reproduction means for reproducing digital data of the playlists detected by the playlist detection means.

2. A reproducing apparatus according to

claim 1

, wherein said reproduction means reproduces the digital data of each of said plurality of playlists detected by the playlist detection means successively from a first one of the playlists.

3. A reproducing apparatus according to

claim 1

, wherein said playlist detection means includes means for detecting data, which is unassociated with playlists, and detects the data unassociated with playlists as one playlist.

4. A reproducing apparatus according to

claim 1

, wherein said playlist detection means detects playlists stored in a plurality of memory media and displays the detected playlists.

5. A reproducing apparatus according to

claim 1

, wherein said playlist detection means sets an order of priority on formats of the detected playlists, and the reproduction means reproduces the digital data of the playlists in the order of the set priority on the formats of the playlists.

6. A reproducing apparatus according to

claim 1

, further comprising select means for selecting a desired one of the playlists detected by the playlist detection means,

wherein said reproduction means reproduces the digital data of the playlist selected by the select means.

7. A reproducing apparatus comprising:

reproduction means for reading out and reproducing data stored in a memory medium;

return means for returning a position of start of reproduction;

final return position storing means for storing a position to which the position of start of reproduction is finally returned by the return means;

return instruct means for instructing a repeat reproduction operation; and

repeat reproduction means for reading out the final return position from the final return position storing means when a return instruction is issued from the return instruct means, and starting the repeat reproduction operation from the final return position.

8. A reproducing apparatus comprising:

reproduction means for reading out and reproducing data stored in a memory medium;

fast-forwarded means for fast-advancing a position of start of reproduction;

final forwarded position storing means for storing a position to which the position of start of reproduction is finally forwarded by the fast-forwarded means;

return instruct means for instructing a repeat reproduction operation; and

repeat reproduction means for reading out the final forwarded position from the final forwarded position storing means when a return instruction is issued from the return instruct means, and starting the repeat reproduction operation from the final forwarded position.

9. A reproducing apparatus comprising:

reproduction means for reading out and reproducing data stored in a memory medium;

return means for returning a position of start of reproduction;

return instruct means for instructing return by the return means;

final return position storing means for storing a final return position to which the position of start of reproduction is finally returned by the return means;

skip instruct means for instructing a skip of a track of the data;

first determination means for determining, when the skip is instructed by the skip instruct means, whether a current position of reproduction is at a beginning of the track or not;

second determination means for determining a relationship among the final return position stored in the final return position storing means, the current position of reproduction, and the track; and

position-of-reproduction determining means for determining a position of reproduction on the basis of determination results of the first determination means and the second determination means.

10. A reproducing apparatus comprising:

reproduction means for reading out and reproducing data stored in a memory medium;

return means for returning a position of start of reproduction;

final return position storing means for storing a final return position to which the position of start of reproduction is finally returned by the return means;

skip instruct means for instructing a skip of a track of the data;

position determination means for determining, when the skip is instructed by the skip instruct means, whether the final return position stored in the final return position storing means is before or after a current position of reproduction in the track which is being reproduced; and

repeat reproduction means for starting reproduction from the final return position when the position determination means is determined that the final return position is before the current position of reproduction, and for starting reproduction from a beginning point of the currently reproduced track when the position determination means is determined that the final return position is after the current position of reproduction.

11. A reproducing apparatus comprising:

reproduction means for reading out and reproducing data stored in a memory medium;

return means for returning a position of start of reproduction;

final return position storing means for storing a final return position to which the position of start of reproduction is finally returned by the return means;

skip instruct means for instructing a skip of a track of the data;

position determination means for determining, when the skip is instructed by the skip instruct means and a current position of reproduction is at a beginning of the track, whether the final return position stored in the final return position storing means is before or after the current position of reproduction; and

repeat reproduction means for starting reproduction from the final return position when the position determination means is determined that the final return position is in a previous track preceding the track in which the current position of reproduction is present, and for starting reproduction from a beginning point of the previous track when the position determination means is determined that the final return position is absent in the previous track preceding the track in which the current position of reproduction is present.

12. A reproducing apparatus according to

claim 11

, further comprising setting means for effecting setting as to whether a determination process by the position determination means is effective or not,

wherein if the setting means is effected setting such that the determination process by the position determination means is not effective, the determination process by the position determination means is not performed.

13. A reproducing apparatus to which a host device is connected via a bus having a current supply function, comprising:

first voltage generating means for generating a power supply voltage on the basis of a battery voltage;

second voltage generating means for generating a power supply voltage on the basis of power supplied from the host device via the bus; and

select means for detecting the presence/absence of power supplied from the host device, and selecting, where no power is supplied from the host device, the voltage generated by the first voltage generating means, and selecting, where power is supplied from the host device, the voltage generated by the second voltage generating means, thereby supplying the selected voltage to respective circuit components.

14. A reproducing method for reproducing digital data stored in a memory medium, comprising the steps of:

storing a final return position when return of a position of reproduction is instructed during reproduction of the digital data stored in the memory medium; and
