BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television apparatus, and more particularly, to a channel display apparatus of a television set so that a predetermined channel is displayed when the television is powered on.

TVs currently in use are equipped with a last memory (last memory) to store the screen state, channel, volume level and the like. Therefore, even when the television is turned off, the final setting state of the television is always stored. When the television is turned on, the microcomputer in the television adjusts the screen state, the display channel, the volume level, and the like of the television in accordance with the settings of various televisions stored in the last memory.

Among the setting states of the TV stored in the last memory, the output state or the volume level such as screen brightness, color, etc. is generally kept constant regardless of the channel being watched, so convenience is obtained by using the last memory function as described above. It becomes possible.

By the way, in the case of the display channel set when the television is turned on, the channel that was finally watched is always displayed when the television is turned on, even though most viewers have a preferred channel that they spend a lot of time watching the television. Therefore, when the preferred channel and the display channel at power-on do not coincide, it is cumbersome to change the display channel using a remote controller or the like.

Therefore, if the display channel at the time of power-on is provided with a function for setting a channel other than the channel of the final viewing, the convenience in use may be further improved.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a channel display apparatus of a television such that, if the user's preferred channel is set, the preferred channel is always displayed regardless of the channel that was being viewed at the end when the television is turned on. There is this.

A channel display apparatus of a television according to the present invention for achieving the above object includes a tuner for tuning a broadcast, a PWM signal section for supplying a PWM signal for broadcast tuning with the tuner, a screen display state and sound level of the television, and the like. A first memory for storing, a second memory for storing a preferred channel set by a user, and adjusting the screen display state and the audio level according to the setting data stored in the first memory when the TV is turned on. And a microcomputer outputting the initial display channel to the preferred channel stored in the memory.

According to the present invention configured as described above, since the preference channel set in advance at the time of power-on of the television always becomes the initial display channel, convenience in use can be improved.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described, referring drawings.

1 is a diagram showing the configuration of a channel display apparatus of a television according to an embodiment of the present invention, wherein reference numeral 1 is an antenna, 2 is a tuner for a broadcasting station, and 3 is an intermediate output from the tuner 2. IF amplification unit for amplifying a frequency (IF) signal.

Further, reference numeral 4 denotes P, for example, which is composed of a surface elasticity and a saw filter for separating the IF signal output from the IF amplifier 3 into an image intermediate frequency signal P and an audio intermediate frequency signal S. A voice processing unit for detecting and processing a voice signal from the voice intermediate frequency signal outputted from the P / S separation unit 4, and 6 amplifying the voice signal processed by the voice processing unit 5 Amplification unit for outputting to the speaker, 7 detects and processes the image intermediate frequency signal outputted from the P / S separation unit 4 and accordingly R (Red), G (Green), B (Blue) and luminance signal An image processor for outputting (Y), 8 mixes the RGB and luminance signals (Y) from the image processor (7) with OSD pattern signals from the OSD generator (12), which will be described later, and a CRT driver (not shown). Is output to the mixer.

Further, reference numeral 9 denotes a remote control unit for setting the basic operation of the television and the preferred channel, 10 is a receiving unit for receiving a remote control signal from the remote control unit 9, and 11 is a predetermined PWM signal to the tuner 2; A PWM signal unit for setting and changing a channel by applying a signal to change the oscillation frequency of the tuner, 12 generates an OSD to generate OSD pattern data for displaying a notice for setting a preferred channel on the screen of a television. The device 13 is a first memory for storing the screen display of the television such as the screen brightness or the screen color and the audio level output and the channel which was finally watched, which has the same function as the last memory in the conventional television apparatus. .

Next, reference numeral 14 denotes a second memory for channel data for setting the preferred channel according to the user's preference for watching TV broadcasting as a display channel when the television is powered on, and 15 denotes the first memory ( 13 is a microcomputer which adjusts the screen display state and the audio level of the television according to the setting data stored in 13) and selects and outputs the initial display channel as the preferred channel stored in the second memory.

First, the setting operation of the preferred channel will be described.

When the user presses, for example, a preference channel setting button installed in the remote control apparatus 9, a corresponding remote control signal is input to the receiving unit 10, and the microcomputer 15 accordingly first displays the OSD generating apparatus 12. By controlling the control panel, OSD text is displayed on the screen to guide the user's preference. Next, when the preferred channel to be set by the user is input through the remote controller 9 or the like, it is stored in the second memory 14.

Next, referring to the operation of the first memory 13 serving as the last memory, the microcomputer 15 changes the setting state of the television related to the storage contents of the first memory 13 by the user. In addition to performing a corresponding control operation, the contents of the first memory 13 are also changed. Therefore, since the latest setting data is always stored in the first memory 13, the finally changed setting state of the television is stored when the television is powered off.

When the television is turned on, the microcomputer 15 controls the initial screen state of the television according to the setting state stored in the first memory 13 and whether the preferred channel is set in the second memory 14. Determine whether or not. As a result of the determination, if the preferred channel is not set in the second memory 14, the channel that was finally watched stored in the first memory 13 is selected and displayed as the display channel.

On the other hand, when the preferred channel is set in the second memory 14, the PWM signal unit 11 is controlled by setting this as the display channel, and thus the channel is set up by the tuner 2.

FIG. 2 is a flowchart for explaining the operation of the preferred channel display apparatus of the television shown in FIG.

The microcomputer 15 determines whether the power of the television is turned on (ST1), and determines whether the preferred channel is set in the second memory 14 when the power is turned on (ST2). Next, if the preferred channel is not set in the second memory 14 as a result of the determination, the microcomputer fetches the channel data finally watched stored in the first memory 13 and selects a display channel based on this. Will be output (ST3).

On the other hand, if the preferred channel is set as a result of the determination in step ST2, the microcomputer 15 fetches the setting data of the channel stored in the second memory 14 and selects a display channel based on the selected channel. To output (ST4).
