Control method for playback in digital multi-function disc device {Method for controlling play in digital versatile disc driver}
[10] The present invention relates to a reproduction control method in a digital multifunctional disc apparatus which limits disc reproduction based on the number of profanity words counted among subtitles or caption data reproduced from the disc.
[11] In general, digital versatile disc devices (DVDs) play back data recorded on optical discs such as DVDs and HD-DVDs. Significantly improved.
[12] On the other hand, the disc used in the digital multifunction disc device is recorded with subtitles, caption data, or audio languages expressed in multiple languages, so that the user can select and play a desired language. It is supposed to be.
[13] In addition, the disc, the grade that can be watched by an adult, adolescent or a child is recorded, which means that the program can be viewed only when the grade set on the digital multifunction disc device and the grade of the disc to be played with each other, This will limit the youth or children from watching adult programs.
[14] In addition, the user may change and set the grade set in the digital multifunction disk device through an appropriate key input such as a password.
[15] However, the general digital multifunction disc device as described above has a problem that, when playing a disc, it is necessary to check each time whether the grade of the disc that the user wants to play and the grade set in the digital multifunction disc device match each other. There is a problem that the rating setting must be changed every time playback.
[16] In addition, even if the grade set in the digital multifunction disc device and the grade of the disc to be played are matched with each other, sometimes subtitle or caption information harmful to the emotions of adolescents or children may be output in the middle of the program. There is a problem that the grade set for the above reproduction restriction becomes meaningless.
[17] On the other hand, in many countries except the United States, the discs are often not rated. In particular, the illegal copies are mostly unrated discs, and the illegal copies are harmful to adolescents or children.
[18] Accordingly, the present invention was created to solve the above problems, and it is possible to determine whether the subtitle or caption information is slanged on the basis of a database of previously constructed slang words to limit the disc playback. It is an object of the present invention to provide a playback control method in a multifunctional disk device.

[19] In order to achieve the above object, a reproduction control method in a digital multi-function disc apparatus according to the present invention comprises: determining whether the character information being reproduced is included in the slang word based on previously prepared slang information; Performing a counting operation each time the character information is included in a slang word; And stopping the disc from playing when the counted value exceeds a predetermined value.
[20] Hereinafter, a reproduction control method of a digital multifunction disc device according to the present invention will be described with reference to the accompanying drawings.
[21] 1 is a block diagram of a digital multifunction disc apparatus to which a reproduction control method according to the present invention is applied.
[22] As shown in FIG. 1, the digital multifunction disk apparatus according to the present invention amplifies and outputs the optical pickup 10 for reproducing the data recorded on the disk D and the data reproduced by the optical pickup 10. An RF (Radio Frequency) unit 11 for detecting wobble data from a disk, a signal processor 12 for signal processing the data output from the RF unit 11, and outputting the data to a predetermined display device; To control the data conversion and to determine whether the subtitle data or the caption data are slang based on the slang language information recorded on the optical disk, and to restrict the playback of the disk. A memory 15 for storing various processing data necessary for the microcomputer 14 and the microcomputer 14 or for storing slang information set by a user; The control of the optical pickup 10 is controlled while controlling the operation of a sled motor for moving the optical pickup 10 under the control of the com 14, or a spindle motor for rotating the optical disk. And a servo unit 13 for performing tracking control and focusing control.
[23] The digital multifunction disc apparatus according to the present invention configured as described above can determine whether or not the subtitle data or caption data currently reproduced on the basis of this slang information is slang, while preliminarily storing and storing information on the slang words in advance. It is determined whether or not.
[24] Thus, when the number of sub-title data or caption data that is profanity exceeds a predetermined number for a predetermined time, the reproduction of the disc is stopped. As described above, if a password set by the user is input in the state in which the disc playback is stopped, playback is continued from the section where the disc playback is stopped. That is, when the adult user sets a password in advance and locks it, and the set password is input, the locking function is released again and playback continues.
[25] 2 is a flowchart illustrating an operation of a reproduction control method in the digital multifunction disc device according to the present invention.
[26] First, in the digital multifunction disc apparatus to which the reproduction control method according to the present invention is applied, slang information previously constructed by a user is stored in a database for example.
[27] As described above, when a disc play command is input by the user in the state of profanity information being constructed, as shown in FIG. 2, the disc play operation is performed (S11). That is, image data, audio data, subtitle data, caption data, and the like recorded on the recording surface of the disc are read and signal processed for output to a predetermined display device.
[28] In this case, character information is extracted from the reproduced subtitle data or caption data (S12), and the databased profanity information is compared with the extracted subtitle data or caption data (S13).
[29] As a result of the comparison (S13), it is determined whether or not the slang information and the extracted subtitle data or caption data coincide with each other (S14). Repeatedly perform the operation of, if match each other, the counting operation for the slang is performed (S15).
[30] FIG. 3 exemplarily illustrates a counting operation for a slang word according to the present invention, and as shown, counts the number of times each slang word is detected during a predetermined counting period. For example, it can be seen that two slang words (F (1), F (2)) were detected in the first counting section (counting section (1)), and one in the second counting section (counting section (2)). It can be seen that the slang word F (1) was detected.
[31] Also, when the second slang word F (2) is detected, the slang word F (2) is recognized as the second slang word in the first counting section (counting section 1), and the second counting section (counting section). (2)) is recognized as the first slang word and is cumulative.
[32] When each of the counting operations S15 is performed, it is determined whether the number counted by the counting operation exceeds a predetermined number (S16). As a result of the determination (S16), the counted number When the number exceeds a predetermined number, the playback of the corresponding disk is stopped (S17). When the counted number does not exceed the predetermined number, the process proceeds to the disk playback step (S11) and repeats a series of operations. do.
[33] The operation of determining whether the number counted by the counting operation exceeds a predetermined number is based on the number of slang words counted during the predetermined counting period, as described above with reference to FIG. As shown in Fig. 4, when a predetermined number of slang words F (L) to F (M) are intensively detected during one counting period, playback is stopped from the corresponding point.
[34] As described above, in the state in which the playback of the disc is stopped, it is determined whether the password set in advance by the user is input (S18), and when the password is input, the disc is continuously played from the section in which the playback of the disc is stopped ( S19).
[35] On the other hand, Figure 5 illustrates a limited disc playback process according to the profanity coefficient according to the present invention, as shown, the number of pronouns detected from the beginning of the disc playback without specifying a specific counting section Can be configured to stop playing the disc from that point if the number is exceeded.
[36] The above-described preferred embodiments of the present invention are disclosed for the purpose of illustration, and those skilled in the art can improve, change, substitute, or add various technical embodiments within the spirit and the technical scope of the present invention disclosed in the appended claims below. It will be possible to.
[37] The reproduction control method of the digital multifunction disc apparatus according to the present invention configured and operated as described above has a ratio of profanity among subtitles and caption information of the disc to be reproduced based on the profanity information previously set and stored and managed. It is a very useful invention that can prevent the play of adolescents, children, and the like unprotected to adult programs by allowing the disc play to be limited if it is out of the appropriate value.
