Description

How to reserve an optical disk system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reservation method in which an information on a track selected by a user can be reserved in particular during the introduction of the contents of a disc.

In general, in an optical disc system, it would be very convenient if the user could roughly know the contents of the disc. Therefore, the optical disc system is provided with a content introduction function that provides an overview of the information of each track by playing the beginning of each track of the disc for a predetermined time.

For example, in the case of a recorded disc, different tracks may be recorded for each track of the disc. So if you play the beginning of each track for 3 seconds, for example, you'll know what tracks are on the disc.

However, while performing the content introduction function, there will be a track that contains information desired by the user. At this time, it is very convenient to reserve the track in advance and then play only the reserved information.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object of the present invention is to provide a reservation method for reserving a corresponding track after reserving the track in advance if desired information is recorded during the introduction of the contents of the disc.

In order to achieve the above object, the present invention provides a reservation method of an optical disc system that reserves desired information by a key signal provided from the outside during contents introduction of each track of the optical disc. Playing the start portion by a preset time; Detecting and storing a track number currently being played when a reserved key signal is provided to the optical disc system; And if the reserved play key signal is provided to the optical disc system, detecting the stored track numbers and sequentially playing only tracks corresponding to the track numbers.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

Fig. 1 shows an overall configuration diagram of an optical disc system for carrying out the reservation method of the present invention.

As shown in FIG. 1, the optical disc system reads the information data contained in the optical disc 100, the optical disc 100, and then reproduces the information data through digital signal processing and MPEG decoding. D (Digital) / A (Analog) converter 120 for converting the video data of the information data reproduced by the disc player 110 to analog, a video signal processor for processing the video signal converted to analog video signal output 130, the D / A converter 150 for converting the audio data of the information data reproduced by the monitor 140, the disk player 110 to analog, to process the audio signal converted to analog and output the audio signal In the audio signal processor 160, the speaker 170, and the content introduction mode, the disc player 110 is controlled such that the beginning of each track of the optical disc 100 is played for a predetermined time. However, if a reserved key signal is provided while the contents introduction mode is being performed, the currently introduced track is detected and stored in the internal memory, and when the scheduled play mode is entered, the disc player 110 is played back to play only each track stored in the internal memory. The control unit 180 and the key input unit 190 to provide a predetermined function key signal to the control unit 180.

2 is a detailed flowchart of a reservation method according to an embodiment of the present invention. A description with reference to FIG. 1 described above with reference to FIG. 2 is as follows.

First, when the optical disc 100 is mounted in the optical disc system, the disc player 110 reads out and plays back a table of contents (TOC) area of the optical disc 100 and provides it to the controller 180, and the controller 180 controls the disc player. The TOC information provided from 110 is stored in the internal memory. At this time, the TOC area of the optical disc 100 includes information on each track of the disc.

Therefore, when the optical disc system is switched to the content introduction mode (S1), the controller 180 detects information on the start point of each track of the optical disc 100 by referring to the TOC information stored in the internal memory (S2). An optical pickup unit (not shown in the drawing) inside the player 110 controls the disc player 110 to be transported to the start point of track No. 1. In this case, the optical pickup unit scans the laser beam on the signal surface of the optical disc 100 and then detects the reflected light reflected from the signal surface of the optical disc 100 to read data. It is a common device that anyone can know.

The disc player 110 jumps the internal optical pickup unit to near the beginning of the first track under the control of the controller 180 (S3), and then moves the optical pickup unit to the starting point of the first track through the track search (S5). Move to (S4). When the optical pickup unit reaches the start point of track No. 1, the controller 180 controls the disc player 110 to play track No. 1 (S6).

The disc player 110 reads information on track 1 of the optical disc 100 under the control of the controller 180, reproduces the information by the digital signal processing and the MPEG decoding process, and the video data is converted into the D / A converter 120. Audio data is provided to the D / A converter 150, respectively. The D / A converter 120 converts video data into analog and then provides the video data to the video signal processor 130, and the video signal processor 130 processes the video signal and provides the video signal to the monitor 140. The D / A converter 150 converts the audio data into analog and provides the audio signal to the audio signal processor 160, and the audio signal processor 160 processes the audio signal and provides the audio signal to the speaker 170.

The controller 180 operates the internal counter when the track is started, for example, when 3 seconds have elapsed (S9) and ends the playback of the track (S10) and detects information on the start point of the next track (S12). ). Then, the disc player 110 is controlled so that the optical pickup unit inside the disc player 110 is transferred to the start point of the next track. The disc player 110 jumps the optical pickup unit to the beginning of the next track under the control of the controller 180 (S13) and then moves the optical pickup unit to the start point of the next track through the track search (S5) (S4). ), Playback is performed for 3 seconds (S6, S9, S10).

As described above, if the user presses a reserved key on the key input unit 190 while the disc player 110 performs the content introduction function while playing the start point of each track of the optical disc 100 for 3 seconds (S7), the controller 180 introduces the current. The track number containing the information being stored is stored in the internal reserved memory (S14). The operation of storing the track number including the information currently being introduced into the reserved memory is performed whenever a reserved key signal is provided from the key input unit 190.

Therefore, when the user provides the reserved playback key signal to the controller 180 using the key input unit 190 (S8), the controller 180 searches whether the reserved track numbers are stored in the internal reserved memory (S15). .

If the reserved track numbers are not stored in the internal memory, the controller 180 controls the disc player 110 to stop the currently executing operation, or the OSD (On Screen Display) or an external display device ( Not shown in the drawing) and this is displayed (S18).

On the other hand, if the reserved track numbers are stored in the internal memory, the controller 180 controls the disc player 110 to sequentially play the information contained in the reserved track numbers (S16). Therefore, the disc player 110 sequentially reads and reproduces only the information contained in the reserved track number through track jump and playback under the control of the controller 180.

After this process, when the introduction of the contents of the last track of the optical disc 100 is finished (S11), or when the reserved play is completed (S17), the controller 180 controls the disc player 110 to terminate the operation of the system. do.

As described above, the present invention has a very convenient effect by reserving the track in advance if desired information is recorded during the introduction of the contents of the disc, and then only reserving the reserved information thereafter.
