Abstract

A method of writing image data files to frame storage means, implemented as an array of disks, on which image data is stored as contiguous clips of frames. A remote system transmits a plurality of data packets over a network in any order, the data packets constituting a plurality of image data files. A local system connected to the frame storage means receives the data packets from the remote system and stores them in a buffer so as to arrange the image data files in a display sequence order. The local system then writes the image data files to the frame storage means as a contiguous clip of frames.

Claims

1. Image processing apparatus, comprising processing means, a network interface, a buffer and frame storage means on which image data is stored as contiguous clips of frames, wherein

said network interface receives a plurality of data packets, wherein said data packets constitute a plurality of image data files to be stored in said frame storage means;

and

said processing means stores said data packets in said buffer so as to arrange said image data files in a display-sequence order and writes said ordered image data files to said frame storage means as a contiguous clip of image frames.

2. Apparatus according to claim 1, wherein

said processing means writes said image data files to said frame storage moans only when a specified period has elapsed without said network interface receiving a data packet that belongs to an image data file that is associated with a specified directory.

3. Apparatus according to claim 2, wherein an image data file that is associated with said specified file directory is defined as one that contains the name of said specified directory in its filename.

4. Apparatus according to claim 2, wherein an image data file that is associated with said specified file directory is defined as one for which said network interface has received at least one instruction that said image data file is to be written to said specified directory.

5. Apparatus according to claim 2, wherein said image data files are sequentially named in said display-sequence order.

6. Apparatus according to claim 2, wherein said processing means is configured to convert said image data files to a format suitable for storage in said frame storage means.

7. Apparatus according to claim 2, wherein said processing means is configured to assess the size of a first image data file and only store image data files that are of the same size.

8. Apparatus according to claim 2, wherein said frame storage means is implemented as an array of disks.

9. Apparatus according to claim 8, wherein said array of disks comprises at least one redundant array of inexpensive disks.

10. Apparatus according to claim 2, wherein said buffer is a portion of said frame storage means.

11. A method of writing image data files to frame storage means on which image data is stored as contiguous clips of frames, comprising the steps of:

at a remote system, transmitting a plurality of data packets over a network in any order, wherein said data packets constitute a plurality of image data files;

at a local system connected to said frame storage means, receiving said data packets from said remote system via said network;

at said local system, storing said data packets in a buffer so as to arrange said image data files in a display sequence order; and

at said local system, writing said image data files to said frame storage means as a contiguous clip of frames.

12. A method according to claim 11, wherein said local system writes said image data files stored in said buffer to said frame storage means only when a specified period has elapsed without said local system receiving over said network a data packet that belongs to an image data file that is associated with a specified directory.

13. A method according to claim 12, wherein said remote system additionally performs the step of issuing at least one instruction to write said image data files to a specified directory.

14. A method according to claim 13, wherein an image data file that is associated with said specified directory is defined as one which said remote system has instructed should be written to said specified directory.

15. A method according to claim 13, wherein said remote system issues an instruction with each data packet to write the image data file comprising said packet to said specified directory.

16. A method according to claim 15, wherein an image data file that is associated with said specified directory is defined as one which said remote system has instructed should be written to said specified directory.

17. A method according to claim 12, wherein an image data file that is associated with said specified directory is defined as one that contains the name of said specified directory in its filename.

18. A method according to claim 12, wherein said remote system additionally performs the step of issuing an instruction, over said network to said local system to create said specified directory.

19. A method according to claim 12, wherein said image data files are sequentially named in said display sequence order.

20. A method according to claim 12, wherein said local system additionally performs the step of converting said image data files to a format suitable for storage in said frame storage means.

21. A method according to claim 12, wherein said local system additionally performs the step of assessing the size of one of said image data files and only storing files of the same size.

22. A method according to claim 12, wherein said buffer is a portion of said frame storage means.

23. A computer system programmed to execute stored instructions such that in response to said stored instructions said system is configured to:

receive from a network a plurality of data packets constituting a plurality of image data files;

store said data packets in a buffer; and

write said image data files in display-sequence order as a contiguous clip of frames to a frame storage means connected to said computer system.

24. A computer system programmed to execute stored instructions according to claim 23, further configured to:

write said image data files to said frame storage means only when a specified period has elapsed without said computer system receiving from said network a data packet that belongs to an image data file that is associated with a specified directory.
