Abstract

The invention disclosed herein is a media recorder for recording live and prerecorded analog audio and/or video information. It is capable of receiving, digitizing, and storing analog audio and/or video information in real time. The invention detects discontinuities in the reception of the analog information and automatically terminates the storage of the information, so the previously received audio and/or video information is stored as a self-contained clip of digitized information. The invention is also capable of receiving and storing digital audio and/or video information from other sources, so that the system can play both the digital audio and/or video information digitized by it and that received from the other sources. This allows both the newly recorded and previously recorded media segments to be evaluated both individually and in context with other segments.

Claims

1. A system for capturing video data defining a moving picture, comprising:

means for receiving the video data from a source;

means for storing, in real time as the video data is received, the video data as a computer data file on a non-volatile random-access computer-readable and rewritable medium according to a discontinuity related to the video data;

means for capturing, in real time as the video data is received, information about the video data, and for storing the information about the video data with the computer data file in which the video data is stored.

2. The system of claim 1, wherein the information includes a length of the clip.

3. The system of claim 1, wherein the information includes a number of video frames per second.

4. The system of claim 1, wherein the information includes a time of recording.

5. The system of claim 1, wherein the information includes start and stop timecodes in the source.

6. The system of claim 1, wherein the video data further includes corresponding audio data of one or more channels, and wherein the information includes an audio sampling rate.

7. The system of claim 1, wherein the video data further includes corresponding audio data of one or more channels, and wherein the information includes a number of audio channels.

8. The system of claim 1, further comprising:

means for organizing the computer data files according to the information stored about the video data.

9. A method for capturing video data defining a moving picture, comprising:

receiving the video data from a source;

storing, in real time as the video data is received, the video data as a computer data file on a non-volatile random-access computer-readable and rewritable medium according to a discontinuity related to the video data;

capturing, in real time as the video data is received, information about the video data, and for storing the information about the video data with the computer data file in which the video data is stored.

10. The method of claim 9, wherein the information includes a length of the clip.

11. The method of claim 9, wherein the information includes a number of video frames per second.

12. The method of claim 9, wherein the information includes a time of recording.

13. The method of claim 9, wherein the information includes start and stop timecodes in the source.

14. The method of claim 9, wherein the video data further includes corresponding audio data of one or more channels, and wherein the information includes an audio sampling rate.

15. The method of claim 9, wherein the video data further includes corresponding audio data of one or more channels, and wherein the information includes a number of audio channels.

16. The method of claim 9, further comprising:

organizing the computer data files according to the information stored about the video data.
