1: PreBee by Screen 200: PreBee by Band Control Program

The present invention relates to a television receiver having a channel programming function using an OSD menu, or a receiving system such as VSI. In particular, in such a system, a screen divided by band when a user pre-parses a programmed channel through an OSD screen. It can be pre parable through to ensure that the ease of pre parable well.

It is being designed to allow a user to program and use channels and broadcasting stations in a form desired by the user in a VSI system having a television reception function using a fully tuned tuner and an OSD screen.

For example, the TV receiver having the auto search OSD function is shown in FIG.

Here, the remote control receiver 52, to which the remote control transmitter 51 is wirelessly connected, is connected to the input port side of the system microprocessor 54, and the keypad 53 for various key operations and the microprocessor for system control. (54), a memory for storing channel selection information, an OSD circuit 60 for displaying OSD characters, etc., a tuner 55 for tuning broadcast signals from an antenna, and an IF signal. The processing unit 56 and the like are provided.

In addition, the video signal processor 57, an audio signal processor 58, and a signal synthesizer 61, which are connected to the rear end of the IF signal processor 56, amplify the video signal and provide the signal to the signal synthesizer 61. , A speaker 59, a water pipe 62, and the like.

In such a system, the tuner 55 serves to electronically tune various channels under the control of the microprocessor 54, and the microprocessor 54 tunes channel data selected from a key part such as a remote control transmitter 51. Is received through the remote control receiver 52 to change the tuning voltage of the tuner 55 to tune a predetermined channel among radio waves received from the antenna.

In the conventional system, the tuner 55 selects an airwave signal at an intermediate frequency and selects necessary information. In this case, when the band-specific information is selected, the microprocessor 54 selects the tuner 55 to perform an auto set. Keep the band at logic 1.

In addition, the band-specific information in Korea is divided into VHF 2-6 channels (VL), VHF 7-13 channels (VH), UHF 14-83 channels (U), etc. and applied to the auto-tuning tuner according to these logics. Band selection and channel selection are made, and this method is called a VS tuning method, and the PR (or CH) found by this is recorded to output the signal.

In addition, the microprocessor 54 controls the tuner 55 and the like, selects the position of characters by data exchange with the OSD circuit 60, displays the occurrence of each character, and displays corresponding channel information on the menu screen. Processing is performed.

In the above system, when the channel program is executed, the OSD screen is set as a manual search, and after pre-searching the channel, in order to check the programmed channel, the user presses an OK button such as a predetermined remote control transmitter and then selects a pre- parable.

As an example, an example of the OSD program for such a channel preset procedure is shown in FIG.

In this case, pressing the menu button from the remote control transmitter of the system will display the menu screen 31 as shown in FIG. 3 (a), and pressing 3 to set the channel from this menu screen 31 will be as shown in (b). The channel preset screen 32 is displayed. If you press No. 1, the manual search screen 33 is displayed as shown in (c), and the channel to be memorized is selected from this screen, and the selected channel is a channel requested by the user. In order to check whether the memory is correct, the procedure is to press the channel analogy button.

In addition, when clearing a channel from the channel preset screen 32, when the number 2 is pressed, the channel clear screen 34 as shown in (d) appears, and the memory channel is cleared through this screen.

However, the pre-vie function to check the memorized channel in advance after the conventional auto search or manual search calls up the menu screen as described above, and brings up the channel preset screen again, and the + and-keys from this channel preset screen. The use of this system was disadvantageous because the preparatory work was performed with a complicated step of selecting a channel and then going through the channel analogy again.

In addition, conventionally, since the channel received after auto search is memorized in the form of PR with only a specific ID without distinction by band, the classification is performed internally through sorting operation. It took a lot of work on the back, which was not desirable.

The purpose of the present invention is to improve the problems as described above, the manual set of the system in the auto search through the pre-vieu screen for each band bands received by each band on one manual set to display the preparable operation By doing so, it is easy to achieve preparable work in such a system.

According to the present invention, if an auto search mode is selected by a user in a channel preset process to implement the above object, searching for a PR having an ID within one cycle of the FDM and storing the searched PR in a band-by-band memory; When the manual search mode is selected by the microprocessor of the system, the microprocessor of the system recognizes this and displays a pre-by-band screen for performing the channel selection function for each band from the screen in which the channel number is divided by band, and for each band. When the user selects the corresponding channel from the Pre-V screen, the selected channel is stored in the memory, and when the channel information confirmation key is input by the user, the channel is displayed. It is characterized by the pre-by-band method of each band.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

3 shows an excerpt of a system circuit block related to the present invention.

In this case, the tuner and the IF unit 41 which tunes the channel by the control signal of the microprocessor 44 from the air broadcasting and processes the intermediate frequency, and are connected to the rear end of the tuner and IF unit 41 are processed by the intermediate frequency. The audio / video processor 42 which demodulates the audio / video signal from the signal and provides it to the rear stage, and the OSD circuit 43 and system control which generate a signal for the OSD screen under the control of the microprocessor 44. The microprocessor 44 is provided.

In addition, the microprocessor 44 is equipped with a band-specific preparatory control program 200 as shown in FIG.

In this case, if there is a broadcast signal input from the antenna (step 201), the channel search checks whether it is auto search (step 202). If it is auto search, it checks whether there is a channel ID. 203).

When there is an ID, a PR having an ID within one cycle of the PWM is searched and stored in a memory, and when it is not, it is a step of checking whether it is in the auto search mode (step 204).

Thereafter, the microprocessor checks whether or not to check the channel information (step 205), and if the user selects the pre- parable function, the microprocessor is configured to display information on the corresponding channel (step 206).

In the manual search mode, if the manual search mode is used, the pre-vieby screen for each band is displayed (1), and if the user sets the channel ID to search from the pre-vieby screen for each band (1), if there is the setting, The PR having the channel ID in the band is stored in the memory (steps 208 to 210).

4 shows an embodiment of the band-specific preview screen 1 related to the present invention.

Here, on the screen where the channel numbers from PR01 to PR55 and the program numbers from P-01 to P-55 are displayed on the manual set screen, these are classified into VHF VL, VHF VH, and UHF for each channel band. It has a function display unit that can directly perform the pre parable function.

The function display section includes, for example, a PR selection column of PR − / + which allows PR to be selected by + and − increase / decrease keys on the remote control transmitter side, a preliminary field by a left button display identifying the searched channel, a channel exchange selection column, It consists of a structure with a column such as OK.

The present invention provides a complicated OSD screen set for the user of the system to pre-parse the already memorized channel information, or to correct a station to be tuned in, to change the programmed channel content, or to perform a down / up operation for channel setting. It can be performed while watching the band-specific preparable screen 1 of FIG.

In this example, when the user calls up the manual set of the band-specific preparatory screen (1) by key operation, the program number PR01 to PR55 and the channel number P-01 to P-55 are displayed on the manual set screen. These channels are divided into VHF VL, VHF VH, and UHF for each channel band, so the user can check the memorized channel contents while viewing the divided screen.

In this case, the channel that the user wants to check is selected through the key selection guide of the PR-/ + PR selection box of the function display unit, the preliminary field, the channel exchange selection field, and the OK key, and the channel defined by the preliminary function can be selected. When the button is pressed, the normal screen corresponding to the channel is displayed.

In other words, when performing the pre-by-band function for each band as described above, the user searches for the contents corresponding to the number for pre-comparison while pressing the increase / decrease key in the PR selection column of PR − / +, and then for If the left button is pressed, the channel information is displayed on the screen.

This operation is performed by the microprocessor 44 together with the preband analog processing program 200 for each band of FIG. 5. In this case, if there is a broadcast signal input from the antenna, the microprocessor (44) passes through the tuner and the IF unit 41. 44 detects a synchronization signal and recognizes a broadcast signal input, and if there is a user's key input for auto search, the microprocessor 44 recognizes the channel ID and checks whether there is a channel ID. (Steps 201 to 203).

When there is a channel ID, the microprocessor 44 searches for a PR having the channel ID within one PWM period and stores the result in the internal memory.

Thereafter, the microprocessor 44 checks whether or not to check the channel information according to the recognition of the key press by the user. If the user selects the pre-vie function, the microprocessor 44 displays the corresponding channel information through the OSD circuit 43. (Steps 204 to 206).

If the microprocessor 44 checks whether the manual search is in the manual search mode, the microprocessor 44 displays the pre-vieby screen 1 as shown in FIG. From step 1), it is checked whether a channel ID to be searched is set, and if there is a setting, a PR having the channel ID in the corresponding band is stored in the memory (steps 208 to 210).

In the present invention, the TV set of a TV tuner having a TV reception function or VSI system or the like does not use a complicated manual set set screen when performing a channel setting, a channel program, or a pre-vie by using an OS screen. Since the analogy and the like can be accomplished from the band-by-band preparable screen divided into bands, such a system has an advantageous feature that it is possible to easily perform channel modification, station change, and station name correction.
