Abstract

PURPOSE:To display information corresponding to a mode so as to be easily seen by selecting information related to the operation of the reproducing device corresponding to its mode, and magnifying and displaying the selected information. CONSTITUTION:Whichever an audio multiplex is stereo, monoral or bilingual is displayed in English character by a voice mode display section on reproducing and recording modes and a voice level is displayed in a belt graph by a voice level display section. Also, the position of a magnetic tape is displayed in the numerals of hour, minute and second by a tape counter display section and a current time is displayed in numeral and English character by a current time display section. Each display on these reproducing and recording modes is done in a normal size. Then, on rewinding and fast forwarding modes, the display of only a VTR operation mode display section and the tape counter display section is done and the counter display section is magnified and displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device of a reproducing device suitable for application to a VTR, a tape recorder, a disk reproducing device and the like.

[0002]

2. Description of the Related Art In a conventional VTR, a display consisting of a fluorescent display tube is provided with a symbol indicating an operation mode such as reproduction, recording, fast forward, rewind, stop, pause and the like, voice-multiplexed stereo, monaural, two-way. Characters that represent voice modes such as national language,
A lot of information such as a figure showing a sound level, a number of hours showing a count value (hours, minutes, seconds) of a tape counter and a character is displayed.

[0003]

As described above, since the display of the VTR displays a lot of information, the VT is displayed when the remote control is used.
In many cases, the display of all information cannot be read from some distance from R. However, all of this large amount of information is not always needed, but some of that information is needed, and the required information varies depending on the mode of operation of the VTR.

In view of the above point, the present invention provides a display device of a reproducing apparatus having a display device and displaying a plurality of information on the display device, the operating mode of the reproducing apparatus among the plurality of information. Accordingly, the present invention intends to propose a display device of a reproducing device that can display necessary information in an easy-to-see manner.

[0005]

According to the present invention, a display device of a reproducing apparatus having a display 7 and displaying a plurality of information on the display 7, the operation of the reproducing apparatus among the plurality of information is described. The information related to is selected according to the operation mode of the reproducing apparatus, and the selected information is enlarged and displayed on the display unit 7.

[0006]

According to the present invention, the information relating to the operation of the reproducing apparatus of the plurality of information is selected according to the operation mode of the reproducing apparatus, and the selected information is enlarged and displayed. To display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a VTR will be described in detail below with reference to the drawings. FIG. 1 shows the display on the display, and FIG. 2 shows the circuit of the display device. This indicator is
It is a bitmap type display such as a liquid crystal display and a plasma display. First, a display example of a display device will be described with reference to FIG. FIG. 1A shows a reproduction mode (recording mode)
Is displayed, and (B) is the rewind mode (fast-forward mode).
Shows the display of.

[Display on Display] (FIG. 1) Display on the display will be described below with reference to FIG. As shown in FIG. 1 (A), the display unit usually includes a VTR operation mode display unit, an audio multiplex broadcast audio mode display unit, left and right audio level display units, a tape counter display unit, and a current time display unit. Is provided.

The operation mode display section of the VTR displays operation modes such as reproduction, recording, fast-forward, rewind, stop and pause with symbols. In FIG. 1 (A), a symbol representing the reproduction mode is displayed, and in FIG. 1 (B), a symbol representing the rewind is displayed.

The voice mode display section displays voice-multiplexed stereo, monaural, and bilingual characters in English characters. The voice level display unit displays the voice level in a graph. The tape counter display section displays the position of the magnetic tape as a recording medium by the numbers of hours (H), minutes (M) and seconds (S). The current time display unit displays the current time in numbers and English letters.

In the reproducing and recording modes, as shown in FIG. 1A, the display is an operation mode display section of the VTR, an audio mode display section of audio multiplex broadcasting, a left and right audio level display section,
The tape counter display and the current time display are all displayed in normal size.

In the rewind and fast-forward modes, FIG.
As shown in, the display displays only the operation mode display section and the tape counter display section of the VTR, and more particularly,
The tape counter display section enlarges and displays. This is because in the rewinding and fast-forwarding modes, it is necessary to monitor the tape position in order to find the beginning of recorded information.

The display on the display in the stop mode is shown in FIG.
The display may be the same as the display in the reproduction and recording mode of (A), or only the operation mode display portion and the enlarged time display portion of the VTR may be displayed. Also, VTR
The display on the non-operating display device may display only the enlarged time display.

Further, when the display device is a color display, it is possible to display different colors for each display unit, or to change the color between the normal display and the enlarged display even in the same display unit. Is also good.

[Circuit of Display Device] (FIG. 2) A circuit of the display device will be described below with reference to FIG.
Reference numeral 1 is a VTR system and a display control CPU.
Information signals necessary for display control are supplied to the CPU 1 together with detection signals from the various parts of the VTR. This information signal includes a CTL signal recorded on or reproduced from the side edge of the magnetic tape, an FG signal for detecting the number of revolutions of the capstan, and recording, reproduction, fast-forward, rewind, stop,
These are an operation mode signal such as temporary stop and a time signal.

A ROM 2 and a RAM 3 for system control of the VTR are connected to the CPU 1 through an address bus A, an address / data bus A / D, etc., and are controlled by the CPU 1.

Reference numeral 7 denotes the liquid crystal display device described in FIG.
Dot map display of 0 × 400 dots is performed. 6
Is a display RAM, which stores display data to be displayed on the display 7. A memory controller 5 is controlled by the CPU 1 and a display controller 4 which will be described later, and is connected to the RAM 6 through the address bus A and the data bus D.
