The method of performing an electronic dictionary function in the optical disk device according to the present invention for achieving the above object, when the electronic dictionary function is performed while reading and playing data recorded on the disk, the ID and the time of the optical disk A step 1 of linking and storing the reproduction time information of the reproduced data together with the recording position of the content retrieved by the electronic dictionary function; And reading out and reproducing the contents of the retrieved word by referring to the ID and the reproduction time information of the optical disc.

Hereinafter, exemplary embodiments of a method of performing an electronic dictionary function in an optical disk device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an optical disk apparatus to which the electronic dictionary function performing method according to the present invention is applied. The optical disk apparatus, for example, a DVD player having an electronic dictionary function, includes an optical pickup 11 and a VDP (Video). Disc Play) system 12, the microcomputer 13, the memory 14, and the OS D generation unit 15, the electronic dictionary DB 16 may be configured to include.

On the other hand, in the microcomputer 13, as described above, the electronic dictionary is performed by a word key input or a scan input in response to a user's electronic dictionary execution request while playing the DVD 10 inserted into the device Search and load the search result data corresponding to the word in the electronic dictionary DB (16).

Then, the OSD generator 15 controls the electronic dictionary search result output to output the loaded search result data as an image.

In addition, the microcomputer 13 performs the electronic dictionary execution by the word key input or the scan input according to the user's electronic dictionary execution request, and then replays the DVD 10 without any new key input or scan input. In order to allow the user to perform any electronic dictionary operation to be performed later, the ID of the reproduced DVD and the reproduction time information of the data reproduced at the time of performing the electronic dictionary together with the recording position of the content retrieved by the electronic dictionary function. It is stored in the memory 14 in association.

The reproduction time information is a presentation time stamp (PTS) of optical disc data corresponding to a point in time when the electronic dictionary function is performed.

For example, as shown in FIG. 2, among the data specifications recorded on the DVD, the disc unique ID is in a lead in area (LIA), and a time point at which an access unit decoded as a synchronization signal of a video and audio signal is reproduced. Presentation Time Stamp (PTS) information that is represented is located on each header on the program stream in the Data Area.

Upon replaying the DVD, the microcomputer 13 searches for the ID (DISC_ID) and the playback time (PTS) of the optical disk stored in the memory, and matches the ID and data reproduction time information of the optical disk currently being played. In this case, an electronic dictionary execution operation is performed on words that have already been searched by the electronic dictionary. Accordingly, the search result data (content) corresponding to the word is searched and loaded in the electronic dictionary DB, and the loaded search result data is output as an image through the OSD generation unit 15. same.
