An optical recording medium for recording a predetermined subtitle code in a predetermined region in which contents are stored, and an apparatus and method to play the optical recording medium which are capable of displaying a subtitle on a screen when the contents are played. The method of playing an optical recording medium includes analyzing a stream that is read from the optical recording medium, and searching whether a predetermined subtitle code is recorded in a reserved region in a predetermined stream, storing the searched predetermined subtitle code and outputting the stored predetermined subtitle code with a command execution key, and signal-processing the predetermined subtitle code that is output with the command execution key, and displaying the signal-processed predetermined subtitle code on a screen of the played optical recording medium.

Optical recording medium and apparatus and method to play the optical recording medium

An optical recording medium for recording a predetermined command code at a predetermined region of contents, an apparatus and method to play the optical recording medium, which executes a predetermined command when the contents are played so that the predetermined command is moved into contents at a predetermined portion of a screen. The method of playing an optical recording medium includes analyzing a signal that is read from the optical recording medium, and searching whether a predetermined command is recorded in a reserved region in a predetermined packet, storing the searched predetermined command and executing the stored predetermined command with a command execution key, and displaying the result of the command that is executed with the command execution key on a screen of the optical recording medium.

Optical recording medium to display stored command along with content, and apparatus and method to play the same

A digital video disk player having a quick playback function and a method of reproducing an optical disc using the digital video disk player. The quick playback function is accomplished by analyzing reproduction control information and searching the titles corresponding to a predetermined title, calculating the running time of each title based on the video title information corresponding to the searched titles, and reproducing the selected title on the basis of the calculated running time. Accordingly, a selective reproduction of a title corresponding to a main movie among a plurality of titles recorded on the disk can be performed.

Method and apparatus for reproducing optical disk player having quick video playback function

A directly accessing apparatus and method of a disk recording and reproducing system, in which scene changes are detected and the very next specific images in the start portions of continuous images after the scene changes are captured, decimated and stored in a temporary storage unit, and the output of the temporary storage unit is edited and recorded on a specific recording area of a disk after a corresponding moving image is entirely recorded on the disk. Accordingly, corresponding moving images can be visually indexed so as to be directly accessed.

Direct accessing apparatus and method of disk recording and reproducing system

A control apparatus for reproducing data from a digital video disk at high speed and a method therefor. The control apparatus including a descrambler for descrambling the data which is read from the digital video disk, demodulated and error-corrected, and detecting a navigation pack sector from the data, a navigation interrupt generator for generating a navigation interrupt if the navigation pack sector is detected by the descrambler, a memory for storing the descrambled data, and a microprocessor for determining a next reproducing position of the digital video disk on the basis of information of the navigation pack sector contained in the descrambled data by accessing the memory if the navigation interrupt is detected, and controlling a driving of the digital video disk.

Control apparatus and method for reproducing data from a digital video disk at high speed

An apparatus for transmitting information via a network, and a method therefor. The information transmission apparatus includes a first device having a transport format converter for receiving user interface data in put via a user interface, the user interface for commanding and controlling the first device, and for converting information into a transport format for transmission, a second device having a display unit, the display unit for displaying the user interface or commanding and controlling the first device, and a physical layer for linkig the first and second devices for communications. The IEEE 1394 interface is adopted as the physical layer, so that the second device can control the operation of a digital versatile disc (DVD) player as the first device, and interfacing between devices using the MPEG-2 transport stream becomes easier.

Apparatus for transmitting information via a network to a device that can display a user interface, and method thereof

An optical disk playback control device in which a signal reproducing portion controls a servo of a digital video disk and reproduces a signal. A data processor demodulates and error-corrects data generated from the signal reproducing portion and processes the error-corrected data according to playback control information. A decoder generates and outputs audio and video data by decoding the data in the data processor. A system microcontroller receives a user's key input signal and applies a control signal to the signal reproducing portion to reproduce the data on a disk, and applies reproduction control to the data processor and the decoder. A memory has a first storage area which is used for demodulation and error correction by the data processor, a second storage area for storing data demodulated and error-corrected in the first storage area and a third storage area for storing playback control information which controls the data of the second storage area, so that the playback control information of the third storage area is read and written by the system microcontroller.

Digital video disk player and reproduction control method thereof

A method for rapidly implementing the data processing for an optical disk in an optical disk recording or reproducing apparatus capable of reproducing data from multiple types of disks. The method includes the steps of turning on a laser of a pickup device, setting the pickup device at an initial position, and driving a timer; obtaining a minimum tracking error point from an optical disk while vertically moving the pickup device from the initial position to the optical disk at a constant velocity; detecting a thickness of the optical disk from a value of the timer at the time when the minimum tracking error point is obtained and from the constant velocity during the vertical movement of the pickup device; obtaining minimum tracking error points between tracks on the optical disk while horizontally moving the pickup device at a constant velocity, at the time when the minimum tracking error point is obtained; detecting a pitch size between the tracks from a period between the minimum tracking error points and from the constant velocity during the horizontal movement of the pickup device; and discriminating the type of disk from the detected thickness of the optical disk and the detected pitch size between the tracks.
