Abstract

PURPOSE:To prevent sudden outputting of voice at a high voice level by regulating the amount of volume outputted at the time of executing timer preengagement from the lowest level gradually to higher level. CONSTITUTION:A receiving set 10 is turned on when time set by a timer arrived by using a microcomputer 11, and at the same time, the voice level of the receiving set 10 is changed slowly from low to high until a specified level is arrived at. The computer 11 is a microcomputer for channel selection and volume control, and as soon as a channel selection signal SS is sent out to a turner 1, a volume control signal SA is sent out to an output amplifier 7. A CRT controlling circuit 12 operates on a receiving instruction of a controlling circuit 20 having functions of clock timer and program timer for picture display. Character signals SC of red - blue are generated from the CRT controlling circuit 12.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a receiver with an automatic volume adjustment device suitable for use in television receivers, radio receivers, stereo receivers, etc. having a timer reservation function. .

[Conventional technology]

Receivers 1, such as television receivers, having a timer reservation function are already known. In this television receiver, when the set timer reservation time is busy, the set power is turned on and the set channel is automatically received. Generally, the set audio level at this time is often output at the same volume that was adjusted immediately before the timer program was executed.

[Problem that the invention seeks to solve]

By the way, when executing such a timer reservation,
The time period of the TV broadcast you watched just before executing the timer program was a time period with relatively high ambient noise (around 7 to 8 a.m.,
When the time is around 7pm or 8pm, the volume of the TV is adjusted quite a bit. The audio is output at the same volume that was adjusted by Vcy4 immediately before the timer program was executed.

For this reason, if the reservation time is set for early morning or late night when ambient noise is relatively low,
When the reserved time arrives, there is an inconvenience in that the audio is suddenly output at a high volume.

Such an inconvenient state can occur not only in television receivers but also in receivers having a timer reservation function, such as radio receivers and stereo receivers.

Therefore, in the present invention, in a receiver having a timer reservation function, the volume output when the timer reservation is executed can be automatically adjusted so that it gradually increases from the minimum level side, thereby solving the above-mentioned problem. This paper proposes a receiver with an automatic volume adjustment device.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention uses a microcomputer αυ as shown in FIG. 1 to turn on the receiver <10 when the time set by the timer arrives, and also The audio level is gradually changed from low to high until it reaches a predetermined level.

[Effect]

When executing the timer reservation, the volume is zero as shown in step 45 in FIG. 4, and the volume increases by one step each time a predetermined time elapses (step 47). Then, when the volume reaches the adjustment target, for example, the volume adjusted immediately before execution of the timer program, the program ends, and the output is thereafter performed at the final adjusted volume.

This is convenient because the sound is not suddenly output at a high sound level. When setting a timer to wake up, the volume will not be adjusted to the volume that was adjusted just before the timer program was executed, but will be adjusted to the volume suitable for waking up.
For example, the program is configured to end when the player steps up to the maximum volume.

〔Example〕

Next, a case in which the receiver with an automatic volume adjustment device according to the present invention is applied to the above-mentioned television receiver having the timer reservation function will be described in detail with reference to FIG. 1 and subsequent figures.

It should be noted that the timer reservation in this embodiment can be performed using the tube surface of the picture tube for television images based on the following reasons.

That is, in general, when reserving a channel/channel only by key operation, there is no way to confirm when and which channel is reserved. However, if the content can be displayed instead of the TV image using the TV screen, it is extremely convenient because the channel reservation can be visually checked, and reservation mistakes can be reliably eliminated.

In addition, this embodiment also has a function that can arbitrarily display the current time etc. on a part of the television screen.

The television receiver shown in Figure 1 (in 1G, (1
) is a tuner, (2) is a video intermediate frequency amplification circuit, (3)
is a video detection circuit, (4) is a ti-eirin output circuit, (5) is a picture tube (CRT), (6A) is an audio intermediate frequency amplification circuit, (6B) is an audio detection circuit, and (7) is an output amplifier. , (8) are speakers.

(Ill is a microcomputer for channel selection and volume control, and the channel selection signal 88 is sent to the tuner (1), and the volume control signal SA is sent to the output amplifier (power). This control circuit has clock timer and program timer functions, and its main body is a microcomputer.
In response to the command, the CRT control circuit (121) built in the character generator operates.
A blue character signal (letters, numbers, symbols, etc.) Sc is generated.

The control circuit ■ is, as is well known, < CPU (2υ, ROM1
23, RAM (23 and l10de-) 124), and a remote control signal from the commander (described later) is input to the input port side of (10/-) via a light receiving element (c).
Further, keys (to) to (c) are connected to the main body of the injured machine.

The key (to) is the mode switching key provided on the receiver body.
In this example, ppc (programmable Pick
Up Center) * - Yes, the key is a timer key that can turn on and off the reservation timer.

The key @ is the key to turn the alarm mode on and off.
In the illustrated switching state (off), the alarm mode is off. αS is a control circuit for a power supply operated by a remote control.

FIG. 2 shows an example of the key layout provided on the commander. The commander (7) selects channels, turns on the power,
In addition to turning it off, it is also used to preset the current time as described above. Among the multiple keys, C311 is a channel direct selection key, the PPC key is a mode switching key with the same function as the one provided on the main body, C3Z is the r+J, r-J key, (Foundation), (To) are the left and right shift keys. (To) is a pencil-shaped clock start key.

In the example, the time is set by a microcomputer.
Channel reservation display etc. is performed. You can set the time by setting "hour" and "minute", but in this example, "year", "month",
The date can also be set at the same time. An example of channel reservation display is shown in FIG. In this case, a channel reservation image is displayed instead of the television image. The channel reservation image is selected by operating the PPC key, and a character signal SC is sent from the CRT control circuit I12, which has received a command from the control circuit ■, so that the background is blue and the characters and symbols are green. .

Now, in the channel reservation mode, as shown in Figure 3, the title "TIMERJ" is displayed on the CRT screen, and next to it is the current day of the week (Monday (MON) - Sunday (SUN)). The time (hours 1 minute 2 seconds) is displayed.If the current time is not set, the day of the week and the current time are displayed with blinking.

The center of the CRT screen is reserved for channels (event reservations)
In this example, three events can be reserved. The reservation details range from "what day of the week and what time to what channel."

The display of "ON" is the on time.

The day of the week is selected from a plurality of preset day of the week setting columns. An example of a day of the week setting column is shown below.

(Currently E3) (Daily) (Mon-Sat) (Mon-Fri)
(±) In this day of the week setting column, MF means every day from Monday to Friday, M-3 means every day from Monday to Saturday, and TDY means setting only for today. Also, "blank" means that the day of the week position is blank, and this is an option for prohibiting execution of the set reserved channel. In this case, if the blank setting is changed, reservation data other than days of the week will be treated as valid.

To select the day of the week setting column, press the "+" key or "-" key (3δ,
It is done by ω. The "+" key selects the day of the week setting column by rotating in the direction of the arrow a, and the day of the week setting column is selected by rotating the "-" key in the direction of the arrow. The cursor "↓" is moved using the left and right shift keys (wealth) and (to) K, and the "hour" setting is from O (hour) to 23 (hour), and the "minute" setting is 00 (minute). ) 00 (seconds) to 59 (minutes) OO (seconds).

Channel reservation is performed from the electronic label channel corresponding to channel display position 1 on the receiver main body to the electronic label channel corresponding to position n.
- J key country, (to). FIG. 3 is an example of a display when a timer reservation is made for "12 channels from 10 a.m. on Sunday."

Figure 4 shows the control circuit ■ and the microcomputer (if
3 is a flowchart showing an example of a display operation according to program data written in the ROM of FIG.

When the program starts, it moves to the main processing routine in step 40'), where it checks remote control data, key manual data inside the receiver, power synchronization input for the clock timer formed using a commercial AC source, etc. I
10 baud) (ROM in CPUc!D via 241)
It is carried out according to the program written in [, and
Processing is performed to realize other display modes such as calendar display.

Next, in step 41, the presence or absence of a timer reservation (channel reservation) is checked, and if there is no channel reservation, the process returns to the main processing step 40, and if there is a channel reservation, the on state of the set is checked in step 42, If the set is on, K moves to step 43, selects the reserved channel, and then returns to step 40.

Therefore, in this case, the volume is not adjusted, and the audio is output at the volume at which you are actually watching TV. This is because in such a case, there is no need to automatically adjust the volume.

When the set is not on, the microcomputer α
The automatic volume adjustment program mode starts according to the program data written in the ROM built into the IIK.

That is, in step 44, a command signal is sent to the AC power supply circuit +151 via I10 port (241) so that the set power is turned on, and the video processing system and the audio processing system are operated.Next, in step 45, The volume is adjusted to zero steps. In this example, the volume can be adjusted in 64 steps as shown in FIG. 5, and when the timer is on, the volume adjustment step is set to zero steps.

After adjusting the volume to zero steps, the process moves to step 46, where the reserved channel is selected, and step 47.
The volume adjustment step is incremented by one step, and the phoneme is raised by one step.

Then, in the next step 48, it is checked whether or not the alarm mode is on, and if it is in the switching state as shown in FIG. 1, the alarm mode is off, so the process moves to step 49.
It is checked whether the adjustment target value, for example, is the same as the volume adjustment step that is the volume adjusted immediately before execution of the timer reservation (last volume).

If the volume adjustment steps are the same, the process returns to step 40 and the automatic volume adjustment mode ends. However, if this is not the case, the process moves to step 51 and subsequent steps. From steps 51 to 54, the state of the volume adjustment step set in step 47 is maintained for a certain period of time (referred to as standby time).
, for example, is a processing step for continuing for 100 m5ecfe, and if there is a remote control input etc. during this period, this automatic volume adjustment mode ends immediately.

When there is a remote control input like this, there is a high possibility that the volume itself will also be adjusted by the remote control input.
This is because continuous execution of automatic volume adjustment mode often becomes meaningless.

Therefore, first, in step 51, a counter that counts the waiting time is set, and then in step 52, the presence or absence of manual key input or remote control input using the key (A) provided on the main body side is checked. If so, please return to step 40.
The automatic volume adjustment mode will stop. However, in the absence of these inputs, the above-mentioned counter is incremented in step 53. And step 5
In step 4, a check is made to see if a predetermined standby time has elapsed since the processing in step 47, and if it is within the standby time, the process returns to step 52, and the presence or absence of manual key input or remote control input is checked again.

If these inputs are not made, the counter is incremented each time, and when the counter contents reach a count number corresponding to the waiting time, the process moves to step 47 via step 54.
The volume adjustment step is again incremented by one.

By repeating this process several times, when the volume based on the incremented volume adjustment step becomes the last volume, this is checked in step 49, so in this case, the process moves to step 40 and the volume automatic adjustment mode is set. ends. Therefore, from then on, the audio is output at the last volume.

If the volume is gradually increased in unit steps in this manner, the user can listen to the audio without much discomfort even when the last volume is quite high.

The adjustment target volume may not be the last volume, but may be set to, for example, a phoneme of about 1/2 to 1/3 of the maximum volume.

In addition, in the volume adjustment step 64, when the last volume corresponds to the 32nd step in the middle, the time required to increase the volume to the volume corresponding to the 32nd step using the processing routine described above is approximately 3.2 seconds. .

Note that when the switch (to) shown in FIG. 1 is switched to the wake-up mode side, it may be inconvenient to adjust to the last volume as described above when the timer reservation time arrives.

For example, if the volume just before the timer program is executed is adjusted to a low level, the volume after executing the timer reservation will be low, making it impossible to confirm whether the reservation has been executed or not, and the function as an alarm cannot be fully expected. Because it will disappear.

Therefore, in such a case, the volume is programmed to be adjusted to a separately set volume for the alarm. Therefore, in step 48, it is checked whether the alarm mode is on or off, and if it is on, it is checked in step 55 whether or not the adjusted volume is the alarm volume. The volume increases gradually with each step. When the volume reaches the alarm volume, the process returns to step 40 and the automatic volume adjustment mode ends.

As the wake-up volume, the maximum volume level is appropriate.

In the case of an alarm, the volume is gradually increased from the minimum to the set value, so the wake-up effect can be exerted in a natural state without causing a sensation of startle.

In the embodiments described above, this invention was applied to a television receiver having a timer reservation function, but it can also be applied to receivers such as a radio receiver, a stereo receiver, etc., which also have a timer reservation function.

〔Effect of the invention〕

As explained above, according to the present invention, the volume is gradually increased immediately after executing the timer reservation, so even if the volume adjusted immediately before executing the timer program is quite high, the volume suddenly becomes louder. Since this is not outputted, the user will not feel uncomfortable or startled by this audio output when the timer reservation is executed.

Therefore, the present invention is extremely suitable for application to a volume adjustment system of a receiver having a timer reservation function, such as a television receiver, radio receiver, or stereo receiver.
