Diagnosis and Prediction Method of Current Status of TV and Video

1 is a configuration diagram of a television displaying on-screen text of the present invention.

2 is a configuration diagram of a video displaying on-screen text of the present invention.

3 is an on-screen character display control flowchart applied to the present invention.

The present invention diagnoses the current state in a device using a microcomputer in television and video. In particular, the present state and the operation of the device corresponding to the information are displayed at the touch of a button. The present invention relates to a method of displaying through a character display device.

Current status diagnostics for devices using microcomputers in conventional television and video have been found using transmitters and brochures. When the user checks the current state by using the transmitter and the brochure, the text is displayed on the screen. Therefore, it is inconvenient for the user to grasp the exact state (informatization specification, etc.) of the device, to recognize the next operation state of the device in advance, and to perform the next operation through the transmitter.

Accordingly, an object of the present invention is to provide a method of displaying on-screen text on current status information and future operation of a device corresponding to this information, which is greatly simplified and much easier to understand the user's operation when displaying text on a screen. Is in.

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

The present invention provides a function that is one step higher in the confirmation function and the help function that a current television or video has. In other words, it predicts the operation of the device that can occur in the future and also displays the character display on the screen that cannot occur in the current state. This is done by reading the current state in the memory inside the microcomputer and comparing the data with the specifications of the device and calculating the result.

First, the operation of the present invention will be described taking an example of a television.

FIG. 1 is a block diagram of a television displaying on-screen text. The key panel 2, the CPU 4, the oscillator 6, the timer 8, the ROM 10, the RAM 12, and the clock timer 14 are shown in FIG. , OSD (On Screen Display) 16, chroma codec 18, CRT driver 20, CRT 22.

Except for the chroma codec 18, the CRT driver 20, and the CRT 22, the remaining circuit parts in FIG. 1 are used in a single chip, and detailed descriptions thereof will be omitted. In television, the chroma codec 18, the CRT driver 20, and the CRT 22 are already known techniques. The chroma codec 18 is connected to the OSD 16, and inputs color signals R, G, and B and luminance signals Y to display the character display provided by the OSD 16 on the screen of the CRT 22. Receive.

In the ROM 10, at least one program for displaying characters on a screen is recorded and stores specifications of the television (fixed values). The RAM 12 stores various function values input by the user to the key panel 2.

As a specific example, the time when the television is turned off and the sleep function are set in the RAM 12 and the timer 8 is in an operating state. Assuming that the time to be turned off in the RAM 12 is set earlier than the sleep reservation time, the CPU 4 displays characters on the screen of the CRT 22 according to the control flow of FIG. A user enters a key through the key panel 2 and displays characters as shown below. Example of operation for key input: "XX turn off time is left and sleep reservation is left XX minutes. Therefore, turn off time operates first and sleep function is canceled." It has the effect of knowing the state.

Next, an on-screen text display will be described as an example of the video.

FIG. 2 is a block diagram of a video for displaying text on the screen. The key panel 2, the CPU 4, the oscillator 6, the timer 8, the ROM 10, the RAM 12, and the clock timer 14 are shown in FIG. , OSD 16, and output port 30. The configuration of FIG. 2 is similar to the television configuration of FIG.

The OSD 16 is controlled by the CPU 4 (data, clock, enable signal), inputs the composite video signal C1, and outputs the composite video signal to the output port 30, that is, the AV output port and the RF output port. Output C2. The CPU 4 further includes four program switches as ports 40 for checking the mechanism operation of the video.

In the second ROM 10, at least one program for displaying characters on the screen is recorded and stores specifications of the television (fixed values). The RAM 12 also stores various function values input by the user to the key panel 2.

In the case of video, the CPU 4 distinguishes between present and absence of tapes in the current video. At the same time, the presence of a safety tab is determined even if there is a tape. Therefore, it checks whether the recording operation is possible in the present state with one key operation. This has the effect of reducing the progress operation at least once in the conventional functional operation.

When the user inputs a character display key to the video through the key panel 2, the CPU 4 controls the character display on the screen to the user according to the control flow of FIG. 3 to be described later. When a user inputs a key through the key panel 2, a character is displayed as an example as follows.

If there is no safety tape on the tape, the words "This tape cannot be recorded. You must insert a safety tape to record." If the tape is not in the video, the message "Current tape is not inserted." Will not play or record, etc. ”is displayed.

Character display control as described above is the same as in FIG. 3, and is performed in the CPU 4 of the television or video shown in FIGs.

Before explaining with reference to FIG. 3, there is a tape with a 60-minute safety tab on the video of the device of the present invention before operation, and one reserved recording program is provided in the ROM 10. Assume that this is the case.

If the key is input from the key panel 2 (step 100), the CPU 4 reads the reservation recording data stored in the RAM 12 (step 102), and the current time through the timer (8). Read related data. The remaining amount of tape in the video is then calculated. In addition, the recording time of the program closest to the current time of the reserved recording program is calculated. The calculated recording time is compared with the remaining amount of the tape to calculate a result value (step 104). At this time, the speed of the tape is compared with the standard, double, triple and so on. The CPU 4 then selects which character to display with the compared result and constructs the corresponding screen display character (step 106).

When the result value is underlined below, the corresponding guidance text (in quotation marks) is controlled to be displayed on the screen through the OSD 16 (Step 3108).

If the recording time is more than 3 hours

"If you perform a scheduled recording X times (where X means the number of times) with this tape, you will not be able to record all of the times you have set. Please insert a tape longer than 60 minutes."

When recording time is less than 180 minutes and more than 120 minutes

"Recording speed X is recorded at 3 times when you perform scheduled recording X with this tape. If you record at 2 times or standard, please insert 60 minutes or longer tape."

When recording time is more than 60 minutes but less than 120 minutes

"If you perform scheduled recording X with this tape, the recording speed will be doubled. If you use standard recording, insert a tape of 60 minutes or longer."

When recording time is less than 60 minutes

"If you execute X record recording with this tape, it will be recorded with the setting you made."

When the CPU 4 which has performed such an operation has passed a predetermined period of time or there is a key input corresponding to the deletion of the screen display, the CPU 4 erases the guide displayed on the screen through the OSD 16 and terminates the process. (Step 112).

As described above, according to the present invention, the user grasps the exact state of the device (TV and video), diagnoses the next operation state of the device in advance, and displays it on the screen. This has the advantage of greatly simplifying the operation and making it easier to understand.
