Abstract

A system and method for direct digital recording of input media such as audio, video, and/or images for easy access and editing are disclosed. The direct digital recording system generally comprises a physical layer configured to receive input media data comprising asynchronous (ASYN) and/or isochronous (ISOC) transactions from an input media capture device, a link layer configured to receive ASYN transactions and convert the received ASYN transactions to a computer readable file system format, a logics chip configured to receive and transmit ASYN and ISOC transactions from and to the physical layer and to receive and transmit ASYN transactions from and to the link layer, the logics chip being configured to convert the ISOC transactions received from the physical layer to ASYN transactions and to selectively convert any portion of the ASYN transactions received from the link layer to ISOC transactions, and a storage having a storage media for storing the data in the computer readable file system format data transmitted from the link layer.

3. The direct digital recording system of claim 1, wherein the link layer is a FireWire link layer adapted to convert asynchronous transactions into data acceptable by said storage media.

4. The direct digital recording system of claim 1, wherein said storage media stores data on the fly as the input media data is captured by the input media capture device.

5. The direct digital recording system of claim 1, wherein the input media capture device is one of an analog camcorder, a digital camcorder, and a digital camera.

6. The direct digital recording system of claim 1, wherein the data stored in said storage transmitted from said link layer is in a file format selected from the group consisting of DV, MPEG2, DV-AVI, AVI, MOV, and JPG.

7. The direct digital recording system of claim 1, wherein the storage utilizes a file system selected from the group consisting of FAT16, FAT32, NTFS, NTFS5, HFS, HFSPlus, FileExchange (DOS), and UNFS.

8. The direct digital recording system of claim 1, wherein the logics chip is a field programmable gate array.
