The present invention relates to a method for automatically editing / duplicate channel selection of a video cassette recorder, and more particularly, to a broadcast signal receiver for receiving a broadcast signal such as a television or a video cassette recorder. Unlike the method of searching and storing sequentially, the receiving channel is automatically edited according to the priority set by the user, and when two or more identical broadcasting stations are received from the edited channel, the user can select the channel having the best image quality. The present invention relates to a method for automatically editing a receiving channel and selecting a duplicate channel so that the user can watch the best screen selected by the user.

In the conventional broadcast signal receiving apparatus, as shown in FIG. 1, the broadcast receiver 1 receives a broadcast signal of a corresponding channel by channel data transmitted from a control unit, and detects whether a video signal is output from the broadcast receiver. The broadcast signal detection unit 3 which transmits the detection result to the control unit, the control unit 5 composed of a microprocessor for controlling all operations of the VCR, and the channel data at the request of the control unit while storing data input from the control unit. It consists of a channel data storage unit 7 to be sent to the control unit, a remote transmitter and a key input unit 9 for key input.

In the conventional broadcast signal receiving apparatus having the above configuration, when the user selects a channel by the key of the remote transmitter and the set main body, the control unit 5 sequentially transmits the channel data to the broadcast receiving unit 1 from the lowest channel frequency. The broadcast receiver 1 receives the broadcast signal based on this data and transmits the received video signal to the broadcast signal detector 3. Subsequently, the broadcast signal detection unit 3 analyzes the input video signal and transmits the video signal detection result to the control unit 5 again. In this case, the control unit 5 determines that there is a detection signal from the broadcast signal detection unit. Data is sequentially stored in the channel data storage unit 7 via the data bus. When the user changes the channel after this operation is completed, the control unit 5 reads the data corresponding to the channel from the channel data storage unit 7 via the data bus and transmits the data to the broadcast receiving unit 1, and broadcasts the data. The receiver 1 was able to receive the channel selected by the user based on this data.

However, in the conventional technology as described above, when receiving a broadcast signal, the channel data storage is stored in the order of low channel frequency to high channel frequency unconditionally, so that the user prefers and stores the channel in order regardless of the priority. The desired number cannot be stored in the channel number, and even when two or more identical channels are received, all the channels are unconditionally stored, so that the same channel is received twice or more when the user changes the channel, causing inconvenience.

The present invention has been made to solve the above problems, and an object of the present invention is to allow a user to first select an arbitrary broadcasting station to a desired channel number before receiving a broadcasting signal of an arbitrary channel, thereby automatically re-editing in this order. It also provides a video cassette recorder's automatic editing / duplicate channel selection method that allows the user to select the best screen when two or more identical channels are received, and to automatically delete other channels so that the user can easily use them when changing channels. have.

In order to achieve the above object, the automatic channel editing method of a video cassette recorder according to the present invention is characterized by a first step of displaying a priority selection screen by determining whether a channel memory key is input and the first step of the first step. If the user selects the priority of the receiving channel while the priority selection screen is displayed, if the priority is selected, the selected channel priority is stored in the memory. If the priority is not selected, the default value of the microprocessor is stored in the memory. In the second step of determining whether or not the search start key is input within a predetermined time period, if the search start key is input, the channel search operation is performed to check and store the station name of the received channel. The third step of performing the step and the selection by the user in accordance with the search results of the third step The channel or the name of the broadcasting station with the highest priority of the channel rearranging for the default of the microprocessor is made of an in the fifth step.

A feature of the redundant channel selection method of the video cassette recorder according to the present invention for achieving the above object is a first step of displaying a priority selection screen by determining whether a channel memory key is input and a priority of the first step. When the user selects the priority of the receiving channel while the priority selection screen is displayed, if the priority is selected, the selected channel priority is stored in the memory. If the priority is not selected, the default value of the controller (here, microprocessor) is used. In the second step of storing in the memory and whether the search start key is input within a predetermined time, and if the search start key is input, the channel search operation is performed to check and store the station name of the received channel. The third step of searching for the channel and the same broadcast as the search result of the third step A fourth step of checking whether the user selects a channel having good image quality by displaying a channel selection screen for selecting the best screen when two or more stations are received; and the priority of the channels according to the check result of the fourth step. As a result, the fifth step is to rearrange the broadcasting station names.

Hereinafter, a preferred embodiment of a method for automatically editing a reception channel / selecting a redundant channel of a video cassette recorder according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of a broadcast signal receiving apparatus for implementing a method for automatically editing a receiving channel / selecting a duplicate channel of a video cassette recorder according to the present invention. As shown in the figure, corresponding data is transmitted by channel data transmitted from a control means. A broadcast receiver 1 for receiving a broadcast signal of a broadcast signal, a broadcast signal detector 3 for detecting whether a broadcast signal is output from the broadcast receiver and transmitting the same to a control means, and a broadcast station name in the video signal inputted from the broadcast receiver. A broadcast station name detection unit 11 for detecting a signal, a control unit 5 for controlling all operations of the VCR, and a channel data storage unit for transmitting channel data to the control unit at the request of the control unit while storing data input from the control unit ( 7) and a remote transmitter and key input unit 9 for key input.

3 is an operation flowchart of a method for automatically editing a reception channel / selecting a redundant channel of a video cassette recorder according to the present invention. As shown in the drawing, the first step includes waiting for a channel memory key to be input (S11 to S12); When the channel memory key is input in the step, the step of displaying the priority selection screen is performed (S13). In the second step, the user selects the priority of the reception channel in the priority selection screen display state of the first step. (S14) to check whether the priority of the receiving channel is selected as a result of the check, and storing the priority value in the memory (S15); and if the priority is not selected as the check result, storing the default value of the controller. In step S16, the third step is for a predetermined time (in this case, a few seconds) that the search start key is input after the operation of the second step is performed. Waiting again (S17), the step of turning off the system if the start key is not entered as a result of the check of the step (S18), and performing a channel search operation (S19) when the search start key is input, A step (S20) of reading and checking a broadcast station name of a channel, a step (S21) of storing the corresponding station name in a memory, and a step of incrementally checking a channel number to check whether it is the last channel (S22 to S23), The fourth step is a step of checking whether two or more identical broadcasting stations have been received as a result of the search of the third step (S24), and displaying a channel screen for selecting the best screen when there are two or more identical broadcasting stations as a result of the check. (S25) and a step of checking whether the user selects a channel having the best image quality (S26), and the fifth step is selected when the user selects a channel having a high image quality as a result of the check in the fourth step. Rearranging the station names according to the user-specified priority while deleting the other channels while maintaining the channel (S27, S29), and when the user does not select the channel of the best image quality, the default value of the control unit (microprocessor) Therefore, it is preferable that the step of arranging the broadcast station name to maintain the first received channel (S28, S29).

4 is a reference diagram for explaining a method for automatically editing a receiving channel and selecting a redundant channel of a video cassette recorder according to the present invention, and (a) shows a priority selection screen for allowing a user to arbitrarily determine the priority of a receiving channel. (B) is an exemplary channel selection screen display so that a channel having the best image quality can be selected when one broadcast signal is received in two or more overlapping channels.

Referring to the configuration described above with reference to the configuration of the operation of the automatic channel editing / duplicate channel selection method of the video cassette recorder according to the present invention.

According to the present invention, the channel reception method is similar to the conventional case, but the step of reading the name of the broadcasting station is added when the channel is received. When the channel memory key is input by waiting for the channel memory key to be input (S12), the Y branch of S12. ) The first step of displaying the priority selection screen (S13) is performed.

When the user selects the priority of the reception channel while displaying the priority selection screen of the first step (S14) and selects the priority (Y branch of S14), the priority is stored in the memory (S15). If no priority is selected (N branch of S14), the second step of storing the default value of the control section 5 in the memory (S16) is performed.

Next, after performing the second step, the system waits for a predetermined time (in this case, a few seconds) to input the search start key (S17) and turns off the system if the search start key is not input (N branch of S17). S18), if a search start key is input (Y branch in S17), a channel search operation is performed to read and check the station name of the received channel (S20), and if there is a station name (Y branch in S20), the corresponding station name is stored in memory. In operation S21, a third step of performing a channel search operation (S22 to S23) to the last channel while increasing the channel number is performed.

Next, as a result of the search of the third step, it is checked whether two or more identical broadcast stations are received from the values stored in the memory (S24), and when two or more identical broadcasts are received (Y branch of S24), the channel having the best quality. Performing a fourth step of checking whether the user selects the best screen (S26) while displaying a channel selection screen indicating a duplicate channel so that the user can select

If the user selects the channel having the best screen as a result of the check in the fourth step (Y branch of S26), the selected channel is maintained (S27) and the other channels are deleted to rearrange the broadcasting station names in order of priority (S29). If the user does not select a channel (N branch of S26), the broadcasting station name is arranged (S29) to maintain the received channel (S28) and then terminates.

Referring to FIG. 4, the overall operation as described above will be described. In other words, when the user determines the priority in the screen display state as shown in FIG. In MBC, the channel data of the current control unit is stored in the channel storage unit in one channel.

In the same manner, other broadcasting stations are processed in the same manner, and when the MBC broadcasting station is received, the channel data is stored in seven channels. After searching all channels by the above process, channels are automatically rearranged according to the user-selected priority. If MBC is memorized in 1 and 7, the screen as shown in (b) of FIG. To display the current channel reception status to the user.

In this case, the user moves the channel by the position movement key and can check and select the best screen directly.

When this check is completed, the best screen data is inputted to the channel from 01 to 06. The channel data that is not copied to 16 is automatically deleted.

This completes the process and the user can only change the channel from 1 to 6 and see the best screen.

In other words, the best screen is automatically rearranged according to the priority selected by the user while eliminating the inconvenience of receiving unnecessary broadcasting again when changing the channel.

For example, when the user determines the priority, when the user inputs a specific key (channel memory) for receiving a channel, a screen as shown in FIG. 4 (a) is displayed.

At this time, the digit keys (0-9) and the position movement keys ( If you prioritize MBC channel to 1, KBS1 channel to 2, KBS2 channel to 3, SBS channel to 4, KBS3 channel to 5, AFKN channel to 6, and (b) A screen like this is displayed.

In case of selecting the best channel, for example, if two MBC broadcasts are received while the screen as shown in (b) of FIG. 4 is displayed, if one channel flickers, one channel is received. ) To receive 7 channels.

That is, when the best screen of 1 channel and 7 channels is finally selected using the channel storage key, when the last selected channel is stored in 1, other channels are automatically deleted.

That is, in the above case, when seven channels are better, when the channel storage key is pressed at the position of seven channels, the display of the right shift key moves to seven channels, and seven data are automatically copied to one channel.

As described above, according to the method of automatically editing / receiving a channel of a video cassette recorder according to the present invention, regardless of the user's taste at the time of receiving a broadcast, the user decides the priority by deviating from the method of sequentially storing low frequencies. In this case, it is automatically reedited according to this priority, and when two or more identical channels are received, there is an advantage that it can be easily used when changing channels by deleting other than the best channel.
