The present invention relates to an optical recording medium reproducing apparatus, and more particularly, to an optical recording medium reproducing apparatus having a network function and a file reproducing method using the same.

In general, it is well known that a DVD (Digital Versatile Disc) is an optical disc having a diameter of about 12 cm that digitizes and records multimedia information that can be executed for about 135 minutes. A DVD may contain multimedia information such as a movie having a TV broadcast quality on a disc having a diameter such as a compact disc (CD). The recording capacity of one DVD is about 6 to 8 times that of a general CD. The light source uses a red semiconductor laser (wavelength of 635 mm to 650 mm) whose wavelength is shorter than that of a CD infrared semiconductor laser (wavelength of about 780 mm). The recording capacity is increased by, for example, increasing the numerical aperture of the objective lens. Multimedia data recorded on a DVD is basically compressed to the MPEG-2 format, which is an international standard.

Such a DVD is generally used as a video recording and storage medium that can contain multimedia information such as high-definition movies, but in some cases it can also be used as a next-generation DVD-ROM of a CD-ROM, a read-only computer storage device. As a result, it is drawing attention in the personal computer (PC), game equipment, and software production industries.

On the other hand, with the recent distribution of various multimedia formats such as MPEG-4, DivX (Digital Video Express), and the like, through the Internet, various multimedia formats and corresponding codecs have also been diversified. For example, recently, DivX-formatted multimedia contents have spread over the Internet to surpass DVD titles, and video multimedia files of various formats have been spread. For reference, the dictionary definition of a codec is an abbreviation of coder / decoder or compression / decompression and is an algorithm or specialized computer program that reduces the storage space occupied by a large file or program. Codecs come in a number of standard ways, some of which are primarily applied to the Internet to reduce file transfer time, and some aim to record as much data as possible on a given disk capacity, such as a CD-ROM. Codecs are widely used in Internet products such as QuickTime, NetMeeting and VOD phones as well as DVD playback devices.

To play a video downloaded to a personal computer using a television, install a video card with a video output function on the personal computer, and then connect the video card and the television so that the user can watch the video played on the personal computer on a television or watch the video. By recording on a storage medium, such as a CD or a DVD, and loading it into a DVD player, a user can watch a video on a television connected to the DVD player.

However, the method of using a video card having an image output function as described above has a problem in that the image output is limited due to noise on a line when the distance between the personal computer and the television is far.
