Description of the Invention: [Technical Field] The present invention relates to a method and system for managing a grading upper limit value of a playable television program, and more particularly to a method for automatically adjusting a playable television program according to user preferences Method and system for limits. [Prior Art] In the analog TVs of the past, TV programs cannot be embedded in the classified information of the programs, and can only be classified in the negative or negative manner in the program list or the title level, such as the general level, the protection level, and the restriction level. It is difficult for the parents to restrict the children to watch the TV. Rong, causing the stage program towel to take care of bad pornography, violence, language and other pictures or sounds, so that the behavior of children is affected by the demonstration of wealth, so in the emerging digital TV technology towel 'TV signal embedded with the content of the program content In order for parents to use the program content management mechanism to monitor the TV programs that their children watch. Today's digital TV content management mechanism is mainly based on the v_chip grading system, and v_chip's heart can prevent wafers or other electronic devices that are over-violent or pornographic TV programs. In the V-Chip grading system, 'the TV program will be divided into G, pG, pG_i3, and R grades according to the age suitable for xin f. In addition to the u age, the v_ehip also proposes the degree of pornography, violence, and language. The restriction on the broadcasting of TV programs, when the rating of the TV program is greater than the preset upper limit of the playable rate, the TV program will be released without any erotic or violent programs. , Ren Xizhi's digital electric fairy ^ management machine _ need the parental guardian slave to grading the upper limit value _ program U can automatically update the grading upper limit according to the viewing preferences and 5 1324017. The program grading system is provided by the TV station, parents Or the guardian may not be able to fully understand the grading system to set the most appropriate grading limit. Therefore, if the user's preference is based on the automatic adjustment of the grading upper limit, the number of times the user can modify the setting and the trouble will be reduced. However, the existing technology cannot be completely close to the user's needs. For example, U.S. Patent No. 5,973,683, which proposes a method for adjusting the grading rules according to the user's appreciation habits, is because of the length of time for the user to watch the program. As a basis for discriminating, a program with a long time may be judged by the system as a program whose preference is shorter than a short time, and affects the adjustment of the final grading rule. In view of the above, the present invention proposes a method and system for adjusting the upper limit value of a playable television program according to the user's preference, in order to sort out the upper limit value of the rating which is most suitable for the user. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method and system for adjusting a computer program knife level upper limit value according to user preferences, which is based on the user's φ preference level based on the number of viewing times of each hierarchical program. Automatically adjust the playable TV program rating upper limit value' to screen out suitable programs for users and block unsuitable programs. Another object of the present invention is to provide a method and system for automatically adjusting the upper limit value of a television program rating, which is in accordance with the user's preference and reduces the number of times the user modifies the setting and the trouble. The re-invention of the invention is aimed at providing a method and system for counting the number of viewings of television programs at all levels, so that parents or guardians can grasp the children's viewing habits. In order to achieve the above object, the present invention uses a program hierarchical management module to store hierarchical information of a television program currently viewed by a user. If the user continuously or cumulatively observes that the television program exceeds a time limit of 6 1324017, the television is added. The rating index of the program is slightly better than the number of people, and the upper limit of the TV program rating can be adjusted according to the amount of the program. 。 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ [Embodiment] Please refer to the digital TV system structure _, this digital TV city owner • from the Internet (10), Wei (10) 104, satellite radio 1 〇 6, and terrestrial wireless broadcast second-class digital TV After the signal is received by the television receiving device (10), it is processed by the battery system (10) and played on the screen 120. The computer system (10) comprises three modules - a signal receiving module (4), a program form management module 112, and a program rating (4) module 114. The signal receiving module 110 is configured to receive a control signal from a user, such as a signal sent by a remote controller or other input device, and the control signals can be commanded by the program form management module 112 and the program rating management module 114. Look for the day program form for a particular channel or select the TV program you want to watch. The program form management module 112 mainly processes an electronic program guide (EPG) embedded in the digital television signal to make the program form accessible to the user for viewing and viewing. Due to the above-mentioned signal receiving module 110 and the program. The function of the form management module 112 is the same as that of the prior art, and therefore will not be described herein. The program grading management module 114 can extract the grading information of the digital television signal and compare it with the preset upper limit value of the pre-programmed television program, and block when the grading of the program content is greater than the upper limit value. This program makes it impossible to broadcast to protect the viewer's mind. The second is a schematic diagram of the television program grading system of the present invention, in which the rating of the television program includes pornography, and the 1324017 grading is hidden to 5.

In addition, the user can set the upper limit of the rating by the user's favorite rating by the user's preference, and the higher the user's miscellaneous index, the upper limit of the television program rating. The greater the influence of the preference, for example, the user's habit is set to 1 to turn off the program grading management, and the grading upper limit value is set. If the user wants to reset the grading upper limit value, the password is entered into the program grading management module 114. It can be reset, and the user can also enter a password to watch the blocked TV program, making the invention flexible. The present invention can record the number of views of each rating index by accumulating the number of views of each rating index to understand the user's preference for the program. Parents or guardians can grasp the children's viewing habits through the grading of the grading. The above description is based on the embodiments of the present invention, and the purpose of the present invention is to enable the skilled person to understand the contents of the present invention, and to limit the number of cases, so that the other disclosures are not disclosed. The equivalent repair (4) modification completed by the spirit shall still be included in the scope of the patent application described below.
