Abstract

A compact disk player employing a high speed digital memory for storing a sample extracted from each program (track) on the disk. A scanning control plays the samples in sequence to a user, who can interrupt the sample playback to select and play the program corresponding to the sample. The digital memory may further store metadata from an external source that describes each program and the metadata may be used to define the location of the samples, and to describe the programs in a program guide which assists the user in selecting desired programs. An archiving mechanism enables the user to build a catalog of all of the programs in the user'"'"'s collection.

Claims

1. The method of reproducing selected programs recorded on one or more compact disk volumes comprising, in combination, the steps of:

mounting a given one of said disk volumes on a playback transport,

employing said playback transport to extract sample content data from each of a plurality of different programs recorded on said given one of said disk volumes,

transferring said sample content data to a high speed random access memory,

accepting a content navigation request from a user,

selectively reproducing said sample content data stored in said random access memory in a form perceptible to said user in response to said navigation request,

accepting a program selection request from said user during or immediately after the reproduction of sample content data extracted from a particular one of said programs, and

reproducing said particular one of said different programs in response to said selection request.

2. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 1 wherein said step of selectively reproducing said sample content comprises the step of automatically scanning said sample content to sequentially reproduce sample content extracted from an ordered sequence of said programs.

3. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 2 wherein said ordered sequence of said programs is established by a playlist stored in said memory.

4. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 2 wherein said ordered sequence of said programs corresponds to the sequence of said plurality of different programs in the order recorded on said given one of said disk volumes.

5. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 2 wherein said sample content data is extracted from the beginning of each of said different programs.

6. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 5 wherein said step of reproducing said particular one of said different programs in response to said selection request comprises the step of employing said playback transport to reproduce the remainder of said particular one of said programs immediately following the reproduction of said beginning of said particular one of said programs stored in said random access memory.

7. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 2 wherein said sample content data includes a predetermined portion of each of said different programs chosen to be representative of the content of the program from which it is extracted.

8. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 2 further comprising the steps of:

employing said playback transport to extract identification information from said given one of said disk volumes;

transmitting said identification information in a metadata request to an available database,

receiving and storing metadata describing the content of said given one of said disk volumes from said database, and

presenting said metadata in a form perceptible to said user in combination with said sample data content in response to said navigation request from said user.

9. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 8 wherein said metadata includes text descriptions of said plurality of different programs recorded on said given one of said disk volumes, and wherein said step of presenting said metadata includes displaying one or more of said text descriptions on a visual display device.

10. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 8 said metadata includes sample content representing one or more said plurality of different programs recorded on said given one of said disk volumes.

11. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 8 wherein said metadata includes the identification of the location on said given one of said disk volumes of at least some of said sample content data.

12. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 8 wherein said available database is located remotely from said high speed memory.

13. The method of reproducing selected programs recorded on one or more compact disk volumes as set forth in claim 12 wherein said available database and said high speed memory are linked by the Internet.

14. The method of reproducing selected programs recorded on a plurality of different compact disk volumes comprising, in combination, the steps of:

mounting each of said disk volumes on a playback transport,

employing said playback transport to extract sample content data from each of a plurality of different programs recorded on the mounted one of said disk volumes,

transferring said sample content data from each of said disk volumes to a high speed random access memory,

selectively reproducing said sample content data stored in said random access memory in a form perceptible to a user in response to a navigation request from said user, and

reproducing a particular one of said different programs in response to a selection request from said user issued during or immediately after the reproduction of sample content data extracted from said particular one of said programs.

15. The method of reproducing selected programs recorded on a plurality of different compact disk volumes as set forth in claim 14 further comprising the steps of:

employing said playback transport to extract volume identification information from each of said plurality of disk volumes,

transmitting said identification information in a metadata request to an available database,

receiving and storing metadata describing the content of each of said plurality of disk volumes from said database, and

presenting said metadata in a form perceptible to said user in combination with said sample data content in response to said navigation request from said user.
