Abstract

The present invention relates to an I/O device capable of collectively managing and easily editing AV data recorded by a plurality of video cameras with transfer bit rate between devices kept constant, and an I/O management system. The I/O management system according to the present invention comprises: a storage device having a non-linear accessible recording medium; a control unit for controlling output of externally supplied data with respect to the storage device, or input of data from the storage device; and one or more I/O device having a record information management unit for managing, through a file system, record information acquired at the time when data is recorded onto the recording medium, and controls input of data from the storage device on the basis of the record information managed by a file system at the time of reproduction.

Claims

1. An input/output device which controls data input/output operations from or to a recording device having a non-linear accessible recording medium, comprising:

input/output control means for controlling output of externally supplied data with respect to the recording device, or input of data from the recording device; and

record information management means for managing, through a file system, record information acquired at the time when data is recorded onto the recording medium, wherein

the input/output control means controls input of data from the recording device on the basis of the record information managed by a file system of the record information management means.

2. The input/output device according to claim 1, further comprising communication means for exchanging at least the record information with another terminal, wherein

when the input/output control means controls input of data from the recording device on the basis of record information that is not managed by the record information management means, the communication means receives the unmanaged record information from another terminal, and

the input/output control means controls input of the data on the basis of the unmanaged record information received through the communication means.

3. The input/output device according to claim 1, wherein

the input/output control means controls input/output of video data or audio data transmitted from a video camera from or to the recording device.

4. An input/output device which controls data input/output operations from or to a recording device having a non-linear accessible recording medium, comprising:

input/output control means for controlling output of externally supplied data with respect to the recording device, or input of data from the recording device; and

communication means for exchanging record information acquired at the time when data is recorded onto the recording medium with a record information management device that manages the record information through a file system, wherein

the input/output control means controls input of data from the recording device on the basis of the record information received from the record information management device.

5. The input/output device according to claim 4, further comprising another communication means for exchanging at least the record information with another terminal, wherein

when the input/output control means controls input of data from the recording device on the basis of record information that is not managed by the record information management means, the another communication means receives the unmanaged record information from another terminal, and

the input/output control means controls input of the data on the basis of the unmanaged record information received through the another communication means.

6. The input/output device according to claim 4, wherein the input/output control means controls input/output of video data or audio data transmitted from a video camera from or to the recording device.

7. An input/output management system comprising:

a recording device having a non-linear accessible recording medium; and

one or more input/output devices which control output of externally supplied data with respect to the recording device or input of data from the recording device, and has record information management means for managing, through a file system, record information acquired at the time when data is recorded onto the recording medium, wherein

the input/output device controls input of data from the recording device on the basis of the record information managed by a file system of the record information management means.

8. The input/output management system according to claim 7, wherein

when the input/output device controls input of data from the recording device on the basis of record information that is not managed by a file system of the record information management means, the input/output device acquires the unmanaged record information through a communication path established with another input/output device.

9. The input/output management system according to claim 7, wherein the input/output device controls input/output of video data or audio data transmitted from a video camera from or to the recording device.

10. An input/output management system comprising:

a recording device having a non-linear accessible recording medium;

one or more input/output devices which control output of externally supplied data with respect to the recording device or input of data from the recording device; and

a record information management device which manages, through a file system, record information acquired at the time when data is recorded onto the recording medium, wherein

the input/output device controls input of data from the recording device on the basis of the record information managed by a file system of the record information management device.

11. The input/output management system according to claim 10, wherein

when the input/output device controls input of data from the recording device on the basis of record information that is not managed by a file system of the record information management device, the input/output device acquires the unmanaged record information through a communication path established with another input/output device.

12. The input/output management system according to claim 10, wherein the record information management device is provided for the each one or more input/output devices.

13. The input/output management system according to claim 10, wherein the input/output device controls input/output of video data or audio data transmitted from a video camera from or to the recording device.
