Abstract
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.
Claims15
A method of reproducing data from an optical disk, comprising:
- analyzing reproduction control information read from the disk and searching titles having a predetermined title reproduction type;
- calculating a running time of each title based on video title information corresponding to the titles searched;
- and
- reproducing the title selected on the basis of the running time calculated for each title.
A method of reproducing data from an optical disk, comprising:
- enabling/disabling a quick video playback function in a user setup menu;
- reading video manager information from the disk;
- searching video title set information of only those titles having a title type in the read video manager information which is predetermined as a sequential program chain title set (One_Sequential_PGC_Title), and detecting the video title information corresponding to the searched titles, if the quick video playback function is enabled;
- calculating a running time of each title based on the video title set information;
- and
- reproducing the title having the longest running time after comparing the running time of each title.
An optical disk player playing a recording medium on which video reproduction information and video title information are recorded, comprising:
- a system controller searching titles having a title reproduction type which is predetermined as a sequential program chain title (One_Sequential_PGC_Title) after analyzing video reproduction information read from the recording medium, and reproducing the title having a longest running time after detecting the running time of each title based on the video title information corresponding to the searched titles.
A method of reproducing data from a storage medium, comprising:
- identifying a title type of each title in video manager information on the storage medium;
- calculating a running time of each title having a specified title type;
- and
- reproducing the title having a longest running time.
An optical disk player having a quick playback function of data from an optical disk, comprising:
- a pickup portion reading optical signals from the optical disk;
- a radio frequency amplifying section converting the optical signals to electrical signals and extracting modulated data and servo signals;
- a digital signal processor demodulating the modulated data, generating compressed audio and video data, and correcting errors using error correction codes;
- an audio/video decoder section decoding the compressed audio and video data and providing video and audio signals to an external display device and speakers;
- a servo section stabilizing servo action;
- and
- a system controller controlling the pickup section, the radio frequency amplifying section, the digital signal processor section, the audio/video decoder section, and the servo section,
- wherein the system controller analyzes information read from the optical disk to identify specific title types, calculates a running time of each identified title, and compares the running time of each title to reproduce the title having the longest running time.
