Description

How to restrict watching by VSI or TV channel

The present invention relates to a VSI system (or TV system; hereinafter, the VSI system is described as an example) to enable viewing restriction of auto-discovered channels for each channel, and more specifically, to an automatic channel. Among the channels searched through the search mode, the channels to be restricted are randomly assigned to the channel list, and specific keys can be used to enable / disable the lock function of the list. The present invention relates to a method for restricting viewing of VSI or TV channels, which can reduce the inconvenience of selecting and restricting channels by restricting selection of channels that are not beneficial at a time.

The conventional VSA (or TV) system has a phase locked loop (PLL) IC, a frequency tuning circuit, a local oscillator, a frequency synthesizing circuit, and the like, as in the embodiment of FIG. A tuner unit 10 for selecting a desired channel, an IF detector 20 for detecting an intermediate frequency signal from a channel tuned by the tuner unit, and an IF detector signal or a line input terminal. An audio signal processor 30 and a video signal processor 40 for separating and processing the audio and video signals from the signal, respectively, are included.

And while controlling the frequency tuning voltage going out to the tuner unit 10 detects the video synchronization provided from the video signal processing unit 40, and if the desired channel is selected to perform automatic fine tuning (AFT) by window search The microprocessor 80 which controls a series of channel selection operations, such as setting an optimum tuning voltage, is provided.

In addition, the OSD processor 50 for OSD processing the video signal by generating a character according to the OSD control signal of the microprocessor, a key input unit 60 for the interface between the microprocessor and the user, a microprocessor driving program and various And a memory unit 70 for storing branch data.

In the conventional VSI system of this configuration, when the automatic channel search mode is selected in the preset mode on the OSD menu screen, the channel with the signal is automatically tuned and memorized, starting with channel "2" and going up one channel to the last channel. It is programmed to display the tuning status on the OSD screen.

That is, when the microprocessor 80 first scans the key input unit and the main menu key is input, the microprocessor 80 outputs an OSD screen as shown in Tables 1 to 3 below, and there is a selection operation by the user on the OSD screen at each output stage. Wait

In this case, when the auto search mode shown in Table 3 is selected by the user, the microprocessor 80 automatically searches for the channel from the first channel to the last channel, and stores the completed channel while storing the channel having the video signal in the memory unit 70. For example, the current search progress is displayed on the OSD screen as shown in Table 4 below.

The operation of searching for and storing the channel and displaying the corresponding channel number on the OSD screen (or the digitron display window) will be explained by taking the case where the last channel (here “69”) is increased by increasing the null value by “1”. And repeat the process until the last channel is displayed, and after all the search channels are displayed for a predetermined time as shown in Table 5 below, the channel search operation can be completed by returning to the menu screen display state.

In VSI having the channel search process as described above, if the user selects an arbitrary x channel on the screen after the automatic channel search function is performed, the channel is moved to the corresponding channel if the corresponding channel number is stored in the channel. If not, the user can arbitrarily select a channel using manual mode.

However, in the conventional VSI system, when the automatic channel fitting mode is executed, the channels searched at that time are set at the same time, so that there are channels that are not favored by the user, especially those that are frequently broadcasted by children. It was cumbersome to find and delete channels one by one, or to intentionally perform resetting while searching again.

Therefore, the present invention was created to solve the above problems, and the present invention resets the channel-specific list by designating channels to be restricted from viewing among channels searched through the automatic channel search mode, and keeps a specific key for a specified time or more. The keystroke operation allows you to turn on / off the lock function for channels that are reset in the list, thereby restricting viewing by limiting the selection of channels that are not beneficial to children. The purpose of the present invention is to provide a method for restricting viewing of VSI or TV channels, which can reduce the hassle of finding and erasing them.

In order to achieve the above object, the present invention provides a first step of waiting for a key input while outputting a preset mode guide screen including a program setting mode when a preset mode is selected in a BSI setup screen output state; A second step of waiting for key input again while outputting a program setting mode guide screen when a program setting mode is selected on the preset mode guide screen; A third step of outputting channels stored in a selection list and determining whether a lock mode setting / release condition for the list is keyed if a list for each channel is selected on the program setting mode guide screen; When the lock mode setting / release condition is keyed in the third step, a fourth step of controlling the lock mode setting / release operation of the corresponding list is provided.

Hereinafter, a method of restricting viewing for each channel of VSI or TV according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a flowchart illustrating a method for restricting viewing of a TV or TV per channel according to an exemplary embodiment of the present invention. As shown in FIG. The first step (S211-S213) of waiting for key input while outputting the preset mode guide screen including the mode, and if the program setting mode is selected on the preset mode guide screen, the key is again displayed while the program setting mode guide screen is output. In the second step (S214, S215) of waiting for input, and when a list for each channel is selected on the program setting mode guide screen, the channels stored in the selection list are output and whether the lock mode setting / release condition for the list is keyed is input. In the third step of determining (S216, S217), and if the lock mode setting / release condition is keyed in the third step, The indicates that comprising the step 4 (S218-S220) for controlling the on / off operation.

That is, the first step may include determining whether the preset mode is selected on the VSI setup screen of Table 2 described above (S211), and if the preset mode is selected, the program setting mode as shown in Table 6 below. Outputting a preset mode guide screen including a step (S212); and checking whether a program setting mode is selected by waiting for key input in the output state (S213).

The second step is performed when the program setting mode is selected on the preset mode guide screen. For example, the step S214 of outputting a program setting mode guide screen as shown in Table 7 on the OSD and In step S215, the controller determines whether a list for each channel is selected by waiting for key input again in the output state.

Program set → First setting program (LOCK) Second setting program Third setting program --- PR +/-: Selection OK: Confirmation menu: End

The third step is performed when a list for each channel is selected on the screen, and outputting the channels stored in the selection list on the OSD screen (S216) and waiting for key input again in the OSD screen output state. Step S217 of checking whether a specific key (for example, an "OK" key) is continuously input for a specified time (for example, 3 seconds) or more.

In addition, the fourth step is performed when a specific key is input continuously for more than the time specified in the third step, and determining the current lock mode execution state of the corresponding channel list (S218), and the lock mode is determined as If the lock mode of the list is set (S219), and if the lock mode is set as a result of the determination, the lock mode of the list is released (S220).

The operation of the present invention as described above is as follows.

First, when the preset mode is selected on the screen while the VSI setup screen of Table 2 described above is output (Y branch of S211), the microprocessor 80 enters the program setting mode as shown in Table 6 above. When the program setting mode is selected while the screen is output again (S212), the program setting mode guide screen shown in Table 7 is displayed on the OSD. Output (S214) and waits again for key input (S215).

At this time, if the channel-specific list is selected in the standby state (Y branch of S215), the channels stored in the currently selected list are output on the OSD screen (S216) and wait for key input again to see whether a specific key is continuously input for a specified time or more. It is checked (S217).

If a specific key is input continuously for a specified time as a result of the check (Y branch of S217), the current lock mode execution state of the corresponding channel list is determined again (S218), and the lock mode of the corresponding list is set according to the determination result (S219). Or release (S220).

That is, if, for example, an arrow is placed at the position of the first setting program and the "OK" key of the corresponding screen is pressed for more than 3 seconds, the selection of the channels that are reset in the first setting program is restricted and then the first setting is again performed. After aligning the arrow with the program position, press the "OK" key for more than 3 seconds to select the channels that are reset in the first setting program.

According to the present invention as described above by specifying the channels to be viewed from among the auto-discovered channels by resetting the list for each channel, so that the lock function for the channels that are reset in the list can be set or released at once, Not only do auto-discovered channels, especially those that aren't useful for children, can be selected at a time, reducing the hassle of finding and limiting viewing and limiting the need for viewing. There is some usefulness that can naturally limit what is happening.
