Abstract

A streaming digital recording system and method uses a video recorder object and first memory in combination with a streaming object to stream video data to a digital storage device from the first memory. Computer readable instructions of the streaming object are operative with the first memory to monitor the first memory for intermediate storage of image data recorded by a video recorder or other data recording device, and to stream the image data from the first memory to a digital or optical storage device. The streaming of video data to a digital storage device can be performed while the first memory continues to receive additional image data, resulting in rapid creation of digital image and video files. The system is also described for use in creating high resolution digital video records of medical and surgical procedures.

21. The digital recording system of claim 19 wherein the streaming object is operative to stream image data to the digital storage device while the first memory receives image data from the video recorder.

22. The digital recording system of claim 19 wherein the first memory receives image data from the video recording during a streaming buffer delay.

23. The digital recording system of claim 19 wherein the first memory is a hard disk having a minimum rotational speed of 7200 RPM and a minimum bus speed of 100 MByte per second, and image data is stored as an encoded video file on the hard disk.

24. The digital recording system of claim 19 wherein the digital storage device is one of the group consisting of a compact disk (CD) storage device and a digital video disk (DVD) storage device.

25. The digital recording system of claim 19, wherein the streaming object is embodied in software, firmware or both.

26. The digital recording system of claim 19 wherein the digital storage device is at least one of a network, a hard disk, or random access memory.

27. The digital recording system of claim 19 wherein image data is stored in the first as data blocks of encoded video frame in an order received from the video recorder.

28. The digital recording system of claim 19 wherein the streaming object streams image data to the digital storage device in an order in which the image data was stored in the first memory.

29. The digital recording system of claim 19 wherein the streaming object is operative to check available storage space in the digital storage device prior to streaming image data from the first memory to the digital storage device.
