Abstract

In a video system, a single key is used to register and delete a channel. To this end, in the automatic program mode when receiving the auto-execution key, the first channel to the last channel are sequentially checked for receiving the synchronization signal, and the channel number where the synchronization signal is received is stored in the memory. In addition, when receiving the automatic execution key, if the manual program mode is received, the channel number is received and the channel number is stored in the memory. At this time, if there is a corresponding channel number, the corresponding channel number of the memory is deleted when the auto-execution key is received.

The present invention relates to an automatic program method of an image system, and more particularly, to a method of registering and deleting a channel.

In general, in a video system such as a television and a VTR, the channel to be used can be registered to easily and quickly select a desired channel. In this case, when the user wants to save and delete the used channel, an auto program key, an erase key, an add key, and the like are used. In this case, the automatic program is a function for storing the signal channels (usable channels) in the memory, the delete function is for deleting the channel stored in the memory, and the add function is used when the user wants to add a channel arbitrarily. to be. However, in order to perform channel save and delete functions, various keys (auto program key, erase key, add key) had to be used, and there are many similar function keys. In addition, in the trend of thin and light miniaturization of video systems, the complexity of the design and the addition of software were necessary due to the arrangement of many keys. There was a problem that the malfunction could be performed.

Accordingly, an object of the present invention is to provide a method for registering or deleting a channel number in a memory with one key when registering or deleting a channel that can be used in an image system.

Hereinafter, the present invention will be described in detail with reference to the drawings.

2 is a flowchart illustrating an exemplary embodiment of the present invention, and illustrates a process of storing or deleting a channel number in the memory 50 according to a mode and a state of the memory 50 when an auto-execution key is received.

Hereinafter, the present invention will be described in detail based on the above-described configuration.

First, an autorun key is installed on the keyboard 10 or the remote controller transmitter 20. In this case, the auto execution key is used to store or delete the channel number in the memory 50. At this time, when the auto-run key is generated from the keyboard 10 or the remote control unit 920, the microcomputer 40 checks the current mode and deletes the channel numbers stored in the memory 50 in the auto program mode. The channel numbers are sequentially scanned to store the channels in which the synchronization signal is detected in the memory 30. When receiving the channel number after receiving the auto-run key, the microcomputer 40 analyzes the contents of the memory 50 and deletes the corresponding channel number if it is stored, and stores the corresponding channel number if it is not present.

The flow of the present invention as described above proceeds as follows.

First, when an auto-execution key is generated through the keyboard 10 or the remote controller transmitter 20, the microcomputer 40 recognizes this in step 201, and checks whether the current mode is an automatic program mode in step 202. At this time, if the automatic program mode, the microcomputer 40 proceeds to step 203 to erase all channel numbers stored in the memory 50 and prepare to perform the automatic program. In step 204, it is checked whether the current system mode is a television mode or a cable television mode. In this case, if it is determined in the television mode in step 204, the final channel number assigned to the television set in step 205, and in step 206, the synchronization signal is detected by the corresponding channel by tuning the frequency according to the initial channel number. Check it. That is, when a synchronization signal is received as the selected channel, the channel becomes a broadcast use channel as a signal signal channel, and when the synchronization signal is not received as the selected channel, the channel becomes a non-broadcast channel as an unsigned channel. Therefore, when the synchronization signal is detected in step 206, the microcomputer 40 stores the channel number in the memory 50 in step 207, and the display unit 60 indicates that the channel number is stored. Thereafter, in step 208, the channel number for checking the presence of a synchronization signal for the next channel is increased by one. In step 209, it is checked whether the increased channel has already been checked, or the process returns to step 206 to perform the synchronization signal check on the next channel again. However, if the synchronization signal is not detected as the corresponding channel in step 206, the channel is a non-broadcast channel as the hand signal channel, and thus, the display unit 60 indicates that the corresponding channel is a no signal channel. To increase the channel number by 1, go to step (209).

Therefore, repeating steps (206) to (210) sequentially increases the channel number of the television, and detects and stores the signal channel from the first channel number to the last channel number in the memory 50.

However, if it is not the television mode in the step (204), since the wired television mode, the microcomputer 40 sets the number of channel numbers of the wired television in the step (211). At this time, the number of channels of the wired television is allocated more than the number of channels of the television, and in this case, the channel numbers requested by the user are stored. The operation repeats steps 212 and 215 while sequentially increasing channel numbers and storing the signal signal channel numbers in the memory 50.

At this time, if the automatic program mode is not in step 202, the microcomputer 40 waits until the channel number is received in step 217. In this case, the user may generate a desired channel number by using a numeric key or a channel up / down key provided on a key matrix of the keyboard 10 or the remote controller transmitter 20. In this case, when a channel number is received through the keyboard 10 or the remote controller receiver 30, the microcomputer 40 accesses the contents of the memory 50 in step 218 to check whether the corresponding channel number is stored. do. In this case, it is determined that the channel is being stored in the memory 50 in step 218, and it is checked in step 219 whether an autorun key is received. When the auto-run key is received, the microcomputer 40 deletes the corresponding channel number stored in the memory 50 in step 220 and displays it on the display unit 60. However, if the auto-execution key is not received in step 219, the controller 1 increases the count value by 1 and checks whether the count is completed. If not, returns to step 219 to wait for the input of the auto-run key. If the state is completed, the routine ends.

Therefore, when the channel number is received after the auto-execution key is input, the microcomputer 40 deletes the channel number according to whether the auto-execution key is generated when the channel number is stored in the memory 40. At this time, if the auto-execution key is not received after a predetermined time, the key input is ignored and the routine ends.

In this case, if it is determined that the channel number received in step 218 is not the channel stored in the memory 50, the microcomputer 40 proceeds to step 223 to receive the auto-run key. In step 223, the microcomputer 40 stores the corresponding channel number in the memory 50 and displays the corresponding state of the display unit 60 in step 224. In addition, the automatic execution key is not received in step 223, and waits for a predetermined time through steps 225 and 226. At this time, if the auto-execution key is received within a predetermined time, the reception channel number is stored in the memory 40. If the auto-execution key is not received to exceed the predetermined time, the reception channel number is ignored and the routine ends.

As described above, when the channel number is registered and deleted in the video system, the channel number can be registered or deleted in the memory by using one key, so the method of use is simple and the program capability of the system can be improved. And it is possible to simplify the program has the advantage that the size and cost of the imaging system can be reduced.
