Abstract

A media system is disclosed that uses preemptive recording of media files to reduce playback latency when media tracks are subsequently selected for playback during the recording process. The media system comprises a primary storage device capable of storing media files and a secondary storage device capable of reading digital media files from a removable storage medium. The system also includes a media player capable of playing media files stored on the primary storage device and a recorder that is connected to read digital media data from the secondary storage device. The recorder stores media files corresponding to the digital media data of the removable storage medium on the primary storage device. To reduce subsequent playback latency when media tracks are selected for playback during the recording process, the recorder automatically stores only predetermined portions of each media file read from the storage medium on the primary storage device when the removable storage medium is, for example, initially engaged with the secondary storage device. The preemptive recording may also occur at advantageous times other than the time at which the removable storage medium is initially engaged with the secondary storage device. Further, preemptive recording may be limited to the media files selected by the user for complete recording from the secondary storage device to the primary storage device.

Claims

1. A media system comprising:

a primary storage device having a first plurality of files containing first media stored in a first data format;

a secondary storage device capable of reading removable storage media, the removable storage media having a second plurality of files containing second media stored in a second data format, where the second plurality of files of the secondary storage device are logically arranged on the removable storage media in a plurality of corresponding tracks;

a media player that plays the first plurality of files from the primary storage device; and

a media recorder that converts the second plurality of files of the secondary storage device to the first data format and stores the converted second plurality of files to the primary storage device, where the media recorder automatically converts and stores a predetermined portion of each track of two or more tracks of the plurality of corresponding tracks of the removable storage media to the primary storage device prior to converting and storing all portions of each track of the two or more tracks of the plurality of corresponding tracks thereby reducing an initial playback latency of the two or more tracks of the plurality of corresponding tracks during playback by the media player when a first track of the two or more tracks of the plurality of corresponding tracks is selected for playback,

where, in response to the first track being selected for playback, the media recorder determines whether all portions of the first track have been converted and stored onto the primary storage device, and

where, if the media recorder determines all portions of the first track have not been converted and stored onto the primary storage device and the media recorder is converting and storing a second track of the two or more tracks, the media recorder preempts the conversion and storage of the second track and converts and stores the first track from the removable storage medium to the primary storage device while the media player plays the first track from the primary storage device.

2. The media system of claim 1 where the predetermined portion of each track of the two or more tracks of the plurality of corresponding tracks comprises a beginning portion of each track of the two or more tracks of the plurality of corresponding tracks.

3. The media system of claim 1 where the predetermined portion of each track of the two or more tracks of the plurality of corresponding tracks comprises approximately five seconds of a beginning section of each track of the two or more tracks of the plurality of corresponding tracks.

4. The media system of claim 1 where the secondary storage device is capable of reading an optical disk selected from a group consisting of a CD audio disc, a DVD audio disc, a super audio compact disc, a DVD video disc, a CD video disc, a CD multimedia disc, and a DVD multimedia disc.

5. The media system of claim 4 where the primary storage device comprises a fixed media storage drive.

6. The media system of claim 5 where the primary storage device comprises a hard disk drive.

7. The media system of claim 1 where the first plurality of files on the primary storage device comprise a plurality of audio files.

8. The media system of claim 7 where the first data format comprises a compressed audio format.

9. The media system of claim 8 where the compressed audio format is selected from a group of compressed audio formats consisting of an MP3 format, an ADPCM format, a FLAC format, and a VORBIS format.

10. The media system of claim 8 where the second data format comprises a lossless audio compression format.

11. The media system of claim 1 and further comprising a user interface having at least a track selection input, where the media player plays one or more files of the second plurality of files corresponding to a given track of the plurality of corresponding tracks of the removable storage media in response to the track selection input, and where the media player begins playing the given track of the plurality of corresponding tracks using the predetermined portion of the given track of the plurality of corresponding tracks stored on the primary storage device.

12. A media system comprising:

a primary storage device capable of storing a plurality of compressed audio files in a first data format;

an optical disk reader capable of reading a plurality of audio files from an optical medium using a second data format, where the plurality of audio files are logically arranged in a plurality of audio tracks;

a media player that plays the plurality of compressed audio files of the primary storage device; and

a media recorder that converts the plurality of audio files read by the optical disk reader to the first data format and stores the converted plurality of audio files in a plurality of corresponding compressed audio files on the primary storage device, where the media recorder automatically converts and stores a predetermined audio portion of each audio track of two or more audio tracks of the plurality of audio tracks on the primary storage device prior to conversion and storage of all audio portions of each audio track of the two or more audio tracks of the plurality of audio tracks on the primary storage device;

where, in response to a track selection event in which a first audio track of the plurality of audio tracks of the optical medium is selected for playback, the media player determines whether all portions of the first audio track have been converted and stored from the optical medium to the primary storage device;

where, if the media player determines that all portions of the first audio track have not been converted and stored from the optical medium to the primary storage device, the media player directs the media recorder to preempt any ongoing conversion and storage of the plurality of audio tracks of the optical medium in favor of conversion and storage of the selected first audio track so that the media recorder continues conversion and storage of the selected first audio track; and

where the media player begins playback of the first audio track using the predetermined portion of the first audio track stored on the primary storage device as the media recorder continues conversion and storage of the first audio track from the optical medium to the primary storage device.

13. The media system of claim 12 where the predetermined portion of each audio track of the plurality of audio tracks comprises a beginning portion of each audio track of the plurality of audio tracks.

14. The media system of claim 12 where the predetermined portion of each audio track of the plurality of audio tracks comprises approximately five seconds of a beginning section of each audio track of the plurality of audio tracks.

15. The media system of claim 12 where the optical disk reader is capable of reading an optical disk selected from a group consisting of a CD audio disc, a DVD audio disc, and a super audio compact disc.

16. The media system of claim 12 where the primary storage device comprises a hard disk drive.
