Abstract

A playback system preferably suited to the post-production environment for displaying high-bandwidth video in real-time or other specified high-speed rate, preferably with the capacity to obtain from networked file servers video with a variety of formats and network file system protocols. The system preferably includes a dedicated server that houses a CPU, an array of high-capacity hard disk drives, and one or more suitable video graphics display controllers. The system preferably stripes video over the hard disk array, preferably in a stripped and uncompressed form so as to facilitate its high-speed output to a display means. Remote user access to one or more functions of the system is preferably provided by a network or web interface, and playback preferably may be controlled via an input device such as a jog/shuttle controller.

Claims

1. A system for displaying high-bandwidth video at a high-speed rate, comprising a dedicated playback server including a CPU, an array of high-capacity hard disk drives, and a video graphics controller, wherein said system is configured to store video on said disk drives in a striped and stripped format, and wherein said system is configured to playback video by outputting it from said disk drives to said graphics controller through direct memory transfers.

2. The system of claim 1, further comprising a display means.

3. The system of claim 1, further comprising a jog/shuttle controller with buttons configured for convenient manual access.

4. The system of claim 1, wherein said high-speed rate is real-time.

5. The system of claim 1, further comprising a playback application loaded on said CPU of said playback server and configured to playback video and to store and organize video data on said disk drives.

6. The system of claim 5, wherein said system is configured to operate in a network environment.

7. The system of claim 6, further comprising a network interface application that provides remote user access to one or more functions of the system.

8. The system of claim 6, wherein said system has the capacity to obtain from networked file servers video with a variety of formats and network file system protocols.

9. The system of claim 1, wherein said system includes at least one SCSI disk controller and is configured to display video at a throughput of approximately 100 Mb/s or greater.

10. The system of claim 1, wherein said system includes at least two SCSI disk controllers and eight disk drives and is configured to display video at a throughput of approximately 400 Mb/s or greater.

11. The system of claim 1, wherein said system is configured to store and display uncompressed video.

12. The system of claim 10, wherein said system is configured to store and display uncompressed video.

13. The system of claim 1, further configured to permit simultaneous video playback on multiple monitors.

14. The system of claim 1, further configured to permit simultaneous display of multiple sequences of frames.

15. The system of claim 1, further comprising an alternate control means remotely connected to said playback server.

16. The system of claim 1, wherein said system is configured to both store and read video data on said disk drives using asynchronous direct I/O.

17. The system of claim 1, further configured to permit a user to select multiple sets of frames of video to be displayed in a set sequence selected by the user.

18. The system of claim 1, further configured to permit a user to manipulate the display of video through the selection and application of color lookup tables.

19. The system of claim 1, further configured to permit the storage of information pertaining to video displayed by said system so as to permit subsequent reference to said information by a user.

20. The system of claim 1, further configured to permit the storage and readout of audio information synchronized with video playback.

21. The system of claim 1, wherein said graphics controller includes a using a processing unit configured to perform uncompressed real-time image processing on video data.
