Description

The present invention relates to a video tape recorder (VTR) that incorporates a microcomputer and performs various controls.

(Prior Art) Conventionally, when power is supplied to a VTR of this type, an initial operating state as programmed in a microcomputer in advance is realized. The table lists these initial operating states.

Some of these initial operation states can be changed by the user's setting operation after the power is turned on, such as those shown in 2, 3, and 5, and those that cannot be changed, such as those shown in 1 and 4. Whether the initial setting of the function setting can be changed or not is determined so that the maker predicts the user's needs and most people can be satisfied.

However, diversification of user lifestyle in recent years and VT
Some users may not be satisfied with the predetermined manufacturer setting specifications due to differences in the R usage relationship and the like. Therefore, when trying to create a set of specifications that meet the needs of each user, the number of types of programs to be stored in the microcomputer increases, so that it is not possible to reduce costs due to mass production effects, and the user is also confused in selecting a model. There were drawbacks.

(Problems to be Solved by the Invention) Conventionally, whether or not the initial operation state of various functions of the video tape recorder can be changed is determined in advance by the manufacturer, so that each user cannot always be satisfied. Sometimes felt that the operability was poor. In view of the above, the present invention has been made to eliminate the above-mentioned drawbacks, and provides a video tape recorder which allows a user to select initial setting data for determining an initial operation state of a conventionally fixed device and change and set the data to a convenient value. It is intended to be.

[Means for Solving the Problems] The present invention relates to a video tape recorder that sets an initial operation state of an apparatus based on initialization data read from a memory when power is turned on. Another nonvolatile memory for holding an initial setting menu for changing initial setting data for determining an initial state of the apparatus, and the initial setting menu from the nonvolatile memory when an initial setting menu selection mode is entered after power-on. Menu output means for reading out and outputting the same to a connected television monitor, and prompting the user to select and specify a selection item, setting value, mode, etc. from an initial setting menu displayed on the television monitor screen. Selection designation means and the data selected and designated by the user from the initialization menu as the initialization data. Has a structure in which and a storage means for storing in memory.

(Operation) In the video tape recorder of the present invention, the menu output means reads out the initial setting menu from the non-volatile memory and outputs the same to the connected television monitor when the initial setting menu selection mode is entered after the power is turned on. I do. The selection designation unit allows the user to select and designate a selection item, a setting value, a mode, and the like from an initial setting menu displayed on the television monitor screen. Thus, the storage means stores the data selected and designated by the user from the initial setting menu in the memory as initial setting data. When the power is turned on, an initial operation state of the device is set based on the initial setting data read from the memory.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of a video tape recorder of the present invention. Reference numeral 1 denotes a front portion of the video tape recorder, which includes a display section 11 including a fluorescent display tube, a power switch 12,
Setting item selection switch 13, Operation state selection setting switch 1
4, TV / VTR switch 15, counter reset switch 16, display and select whether the TV monitor is the tuner side of the television or the output side of the video tape recorder, display the time, or display the counter value A portion according to the present invention, such as a display changeover switch 17 for switching whether or not to perform, is provided. In particular, the switches 13 and 14 are provided in portions that can be hidden by the operation button door 15. It is assumed that the video tape recorder incorporates a microcomputer (not shown) that performs the operation of the entire apparatus and data processing necessary for the operation.

Next, the operation of this embodiment will be described with reference to the operation flowchart of the microcomputer shown in FIG. When the microcomputer in the video tape recorder detects that the power switch 12 is turned on in step 201 of FIG. 2, in step 202, a display based on the initial setting data of each function held in the RAM is displayed on the display unit 11. Done to
Next, the process proceeds to step 203, where the microcomputer determines whether or not the mode is the initial setting menu selection mode, and if the mode is the selection mode, the process proceeds to step 204;
Go to 08. In step 208, various operations and display of the VTR are controlled based on the initial setting data in the RAM. On the other hand, in step 204, the initial setting menu data is read from the ROM or the like, and a display based on this data is displayed on the display unit 11, and the initial setting menu data is displayed on the television monitor via RF output or the like. FIG. 3 is a diagram showing an example of initial setting menu data displayed on the screen of the television monitor. When the user presses the setting item selection switch 13 while viewing this screen, the microcomputer performs a process of moving the shaded portion in the figure to the next setting item portion, and can select a setting item. When the selection of the setting item is completed, the operation state setting switch 14 is pressed to determine the setting value. That is, when the operation state setting switch 14 is pressed, the microcomputer cyclically changes the position of the underline A corresponding to the corresponding item and the numerical value in the box to perform the numerical value or mode setting operation. When the setting of each setting item is performed by the user in this manner, the microcomputer performs the above-described selection item selection operation and the setting value and mode setting operation in step 205, and then proceeds to step 206.
It is determined whether or not the initial setting menu selection operation is completed by checking whether the power switch 12 is on or off. If not, the process returns to step 205. If it is determined that the power switch 12 is turned off, the process returns to step 207. Go to In step 207, the setting value and the mode selected by the user are written in the RAM as initial setting data.
Return to

FIG. 4 shows an example of the change of the initial setting data by the processing of the above step 205. In comparison with that of FIG. 3, the start channel position 1 is changed to 3, and the TV / VTR switch is changed.
15 is changed from TV to VTR side, the display is changed from time to counter, and the above set value and mode are changed to VTR
Is written to RAM as initial setting data. Therefore, the next time the power is turned on, the display on the display section 11 of the VTR and the mode of each switch are based on the changed initial setting data.

According to the present embodiment, by providing the built-in microcomputer with the initial setting data change program and the setting item selection switch 13 and the operation state selection setting switch 14 on the front panel section, the initial setting data for determining the initial state of the apparatus can be changed by the user. Can be changed by For this reason, the state most used by the user can be set as the initial state when the power is turned on, so that the number of operations until the operation of the VTR is started is reduced, and the operability of the apparatus can be significantly improved.
For example, when a user who always uses a VTR in the initial state shown in FIG. 4 uses a conventional VTR, (1) the TV / VTR switch 15 is set to the VTR mode. (2) Adjust the channel position to 3. (3) Switch the display to the counter side. (4) A series of operations of resetting the counter (adjusting to XX) must be performed every time the power switch 12 is turned on, but in this example, these operations are not required. Further, in the present embodiment, the programs in the microcomputer are not changed according to the needs of the user, so that VTRs having the same program can be mass-produced, and the mass-production effect is not impaired.

[Effects of the Invention] As described above, according to the video tape recorder of the present invention, the user can select the initial setting data for determining the initial operation state of the device which has been conventionally fixed and change and set it to a convenient value. There is.
