Abstract

An integrated apparatus is disclosed that can directly connect to a portable digital video camera and can record uncompressed video and audio data, along with associated metadata, in the field and elsewhere. Most preferably, the integrated apparatus includes a removable, recordable, reusable digital magazine that may be mounted. Most preferably, the integrated apparatus also supports a variety of input and output formats, and the apparatus may be easily connected to other computing systems, either directly or through network connections, wired or wireless. The digital magazine can be mounted in a variety of docking stations and can be directly connected to a network, allowing the video and audio data to be easily stored and transferred.

Claims

1. A portable digital film recording system comprising:

a portable case;

a computer;

a display;

at least one removable, reusable, computer-readable digital data storing, digital magazine;

the digital magazine storing the computer-readable digital data, real-time, in DPX file format;

the digital data comprising uncompressed high definition video footage, uncompressed audio footage, and metadata;

the digital magazine comprising;

a backplane;

at least two digital storage devices electrically coupled with the backplane; and

at least one low insertion force connector, electrically coupled with the backplane;

the digital magazine having a data transfer rate of at least four gigabits per second from the at least two digital storage devices through the low insertion force connector;

a digital magazine receiver comprising;

a backplane; and

a low insertion force connecter, shaped to removably engage the low insertion force connector of the digital magazine;

a control and connector panel, including one or more connectors shaped to removably, electrically couple with at least one external device;

the at least one external device comprising;

a camera, a video monitor, an audio recorder, headphones, a computer network, an edit controller, a microphone, or a signal generator;

software operative on the computer to facilitate communication between the at least one external device and the digital magazine; and

at least one power source;

the portable digital film recording system having a total weight of not over 50 lbs.

2. The portable digital film recording system of claim 1 wherein the power source is used to turn power on the film recording system, and wherein the digital magazine can be removed from the film recording system without turning the power off the film recording system.

3. The portable digital film recording system of claim 1 wherein at least a portion of the digital data is stored in at least one of the following formats HD, HD RGB, or 2K.

4. The portable digital film recording system of claim 1 wherein the audio footage comprises 6 or 8 channels.

5. The portable digital film recording system of claim 1 wherein the reusable digital magazine holds up to 54 minutes of DPX RGB file images.

6. The portable digital film recording system of claim 1 further comprising at least one of an RS422 control, a USB serial port, an Ethernet connection, a RS232 control, a wireless network, a USB port, a port designed to directly connect to a camera, or a Firewire port.

7. The portable digital film recording system of claim 1 wherein the control and connector panel further comprises up to 38 connectors for connecting to external devices.

8. The portable digital film recording system of claim 1 further comprising at least two power sources, the second power source further comprising at least one of a battery, an AC power source, or a DC power source.

9. The portable digital film recording system of claim 1 wherein the software further comprises at least one converter which converts digital information from one format to a different format.

10. The portable digital film recording system of claim 1 wherein the computer controls the digital film recording system and wherein the computer is controlled by a remote computing device.

11. The portable digital film recording system of claim 1 wherein the at least one external device is operable to provide for viewing of the digital data without further processing of the digital data.

12. A method of recording video, the method comprising:

providing a portable recording apparatus comprising;
