Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from Korean Patent Application No. 10-2007-0100468, filed on Oct. 5, 2007 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF INVENTION

1. Field of Invention

Apparatuses and methods consistent with the present invention relate to a video processing apparatus and a control method thereof, and more particularly, to a video processing apparatus which stores video data in an external storing unit in a file system for a video play/edit function, and a control method thereof.

2. Description of Related Art

In general, a video processing apparatus such as a television or a set top box receives video data through a broadcast signal from a broadcasting station and processes the received video data to display an image. Recently, a video processing apparatus has been under development which can store video data after receiving it as well as while receiving it so as to use the video data whenever necessary.

Such a function of the video processing apparatus is referred to as a video play/edit function. A Personal Video Recorder (PVR) is an example of such a function. This function may include storing an image of a channel under broadcasting, still frame display, rewind, play slow, jump, edit, etc.

The video data for the video play/edit function is stored in a storing unit provided in the video processing apparatus, and may be stored in a computer for preservation or extension of use of the video data, etc. In the latter case, an external storing unit such as an external hard disk is employed to move the video data to the computer.

However, the video processing apparatus typically stores the video data in the storing unit in an exclusive use file system for the video play/edit function only, not in a file system such as FAT32, NTFS, etc. which is generally employed in the computer. This is because the file system such as FAT32, NTFS, etc. is employed for a general use computer system, and is not suitable for supporting a special function such as a video play/edit function. The exclusive use file system for the video play/edit function has a restoring function for use when the file system malfunctions and has an optimal speed for writing/reading a large size of file, but the general use file system does not.

Accordingly, in the case that the computer employs the video data stored in the external storing unit, an operation system of a computer such as MS-Windows can not recognize the exclusive use file system for the video play/edit function. Thus, a driver for the exclusive use file system should be installed in the computer in order to allow the computer to recognize the exclusive use file system.

Conventionally, the driver for the exclusive use file system is installed in the computer through a separate driver CD in which a driver installation program is stored. However, this causes inconvenience in that a user should manage the driver CD in addition to the external storing unit. Further, the driver CD increases the manufacturing cost of the video processing apparatus.

SUMMARY OF INVENTION

Accordingly, it is an aspect of the present invention to provide a video processing apparatus and a control method thereof which can effectively use a computer for a video play/edit function.

Additional aspects of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the present invention.

The UI may include items for partition-dividing of the external storing unit 200, formatting, file reproducing/storing, etc. A user may select a suitable item through the UI to make the video processing apparatus 100 perform a desired operation.

The controller 160 stores the video data in any one of a plurality of partitions of the external storing unit 200 in the video file system, and stores the driver installation program in another partition in the computer file system. The controller 160 may reproduce the driver installation program stored in the storing unit 140 into the external storing unit 200 to store the driver installation program.

If the external storing unit 200 is not pre-divided into the plurality of partitions, the controller 160 may divide the external storing unit 200 into a plurality of partitions before storing the driver installation program. For example, as shown in FIG. 2, the controller 160 may divide the external storing unit 200 into a first partition 210 and a second partition 220, and then, format the first partition 210 in the FAT32 file system and format the second partition 220 in the video file system. In the present embodiment, the first partition 210 may have such a size that the driver installation program can be stored therein, and the remaining items to be stored may be allocated to the second partition 220. The controller 160 reproduces and stores the driver installation program of the video file system stored in the storing unit 140 into the first partition 210, and stores the video data in the second partition 220.

If the external storing unit 200 in which the video data and the driver installation program are stored is connected to the computer 300 through the video processing apparatus 100, a driver of the video data is installed into the computer 300 by the driver installation program stored in the first partition 210. The computer 300 can recognize the video data in the second partition 220 through the installed driver.

As described above, the video processing apparatus 100 according to the present embodiment can store the video data and the driver installation program for allowing the computer 300 to process the video data in the external storing unit 200, without a separate driver CD.
