Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and more particularly to a technique for producing a video effect that creates a sense of unity between a television and a viewer when the power is on or off. Is.

[0002]

2. Description of the Related Art In a conventional television receiver,
When the power is turned on, the program on the same channel as the reception channel when the power is turned off is immediately displayed on the entire screen (full screen), and when the power is turned off, the program that was being displayed up to that moment is almost instantaneous. It just disappeared.

[0003]

As described above, in the conventional television receiver, when the user wants to watch the television, the program being broadcast is immediately displayed on the full screen when the power is turned on. Although it was the contact point for information, it was dull without showing any so-called greetings. Also, when you turn off the power after watching a program, you have to leave the screen where your consciousness was concentrated until then and do some other work or get to the floor. I couldn't give the TV side any kind of impetus or momentum.

The present invention was devised in view of such circumstances, and provides a kind of sense of unity between the television and the viewer so as to make the television more familiar. The purpose is to increase.

[0005]

A television receiver according to a first aspect of the present invention provides a means for displaying a received image on a sub-screen when the power is turned on and a received image displayed when the power is turned on. Means for displaying a message screen informing the start on the parent screen, means for executing the child screen display and the parent screen display for a predetermined short time in the initial period of power-on, and the deletion of the message screen followed by the child screen And a means for zooming up.

When the power-on operation is performed, the received image is displayed on the child screen, and at the same time, a message screen indicating that the viewing of the received program is about to start is displayed on the parent screen, and such a display state is short. After the time has passed, the message screen is erased, the sub-screen displaying the received image is zoomed up, and the normal received image display screen (full screen)
And At the start of viewing, there was a message (speaking) from the TV side to the viewer, such as "welcome," and then the received image seemed to be zoomed up and approached, and the viewer turned it on. Since it is viewed together, a fun and entertaining video production that is not possible with a conventional television receiver is produced. As a result, the viewer feels some kind of psychological unity or expectation with the television when he or she is about to watch the television, and the television becomes familiar with the television.

According to a second aspect of the present invention, there is provided a television receiver in which a means for zooming down from a full screen displaying a received image to a small screen along with a power off operation, and a power off operation after the zoom down. It is characterized in that it is provided with means for displaying a message screen for notifying the accompanying received image deletion on the parent screen for a predetermined short time, and means for turning off the power after the display of the message screen is completed.

[0008] With the power off operation, there is a feeling that the received image is moved away from the viewer by zooming down the received image from the full screen to the sub screen, and then the program viewing is ended. A message screen like this appears, giving the viewer a feeling that the viewing is actually over. This is also an interesting video production, and the viewer feels a kind of satisfaction, "I have finished watching." This is also something that was not the case with conventional television receivers, and I felt a sense of unity with the television, making the television feel more familiar.

According to claim 1 or claim 2,
The message screen may be a display of only characters, a display of only text messages, or a simultaneous display of characters and text messages.

When the message screen is displayed, a voice message corresponding to the screen may be simultaneously given.

When a character or a character message that moves in a certain manner is displayed as a message screen, or a voice message is also output, a more interesting staging effect is exerted and empathy becomes stronger.

Reference numeral 14 denotes a character storage unit which stores characters which are temporarily displayed on the main screen when the power is turned on or off and which sends a certain kind of image message to the viewer and drawing data of the character message. The character storage unit 14 has a built-in D / A conversion circuit on the output side. "Character" here means "characters", "codes", and "numbers" that are generally meant in the field of computers.
Is different from. Further, although the display form is slightly similar to the "agent" (agent) of the knowledge navigator software, it does not have an intellectual function, but has a different concept. Rather, it is more commonly referred to as a so-called "character" in video games (characters, animals, etc.). You can call it a "messenger." However, this character cannot be arbitrarily moved by the user, and should be regarded as having a certain movement on the screen.

In the character storage unit 14, drawing data for a number of fields indicating the movement of the character for about 1 to 2 seconds when the power is turned on is separately stored in three types, that is, morning, daytime and nighttime. ing. Similarly, three types of drawing data when the power is turned off are also stored. Therefore, the character storage unit 14 stores six patterns of drawing data. Drawing data, in addition to data showing the posture, facial expression, position, etc. of the character at a certain point,
It may also contain character data.

For example, when one pattern of the voice message is "Hello, ○○-san", if the user name is "Yamamoto", by inputting the voice data "Yamamoto" from the microphone 21, the voice message " Hello, is determined as Yamamoto-san ", is of the determined voice message is registered in the memory of the recording and playback unit 20. The playback operation of the recording / playback unit 20 is also controlled by the read control unit 17, and a voice message is output in synchronization with the reading of the character drawing data performed when the power is turned on or off. Note that the switch 26 is turned off after the user name is registered.

Reference numeral 22 is an audio signal processing circuit for processing the audio signal separated from the television receiving circuit 6, 23 is an audio output circuit connected to the audio signal processing circuit 22 and the recording / reproducing section 20, and 24 is a speaker. A switch 25 is inserted between the image storage unit 8 and the mixing unit 18, and can be turned off by a command signal q from the clock control unit 12.

Next, the operation of the television receiver configured as described above will be described.

First, the operation when the power is turned on will be described with reference to the schematic timing chart shown in FIG. When the power-on operation signal transmitted from the infrared remote control device is received by the remote control receiving unit 1 or when the power-on operation is performed on the operation panel unit 2, the power-on signal c is output and the power control unit 3 is operated. Immediately after that, the power supply circuit 4 is started up, and each unit becomes operable. The power-on signal c is also input to the on / off control unit 5 and puts the on / off control unit 5 into a power-on detection state. When the ON signal j is output from the ON / OFF control unit 5 to the switch switching unit 13, the switch switching unit 13 immediately switches the changeover switch 7 to the contact b side and connects the television receiving circuit 6 to the image storage unit 8. . The ON signal j from the ON / OFF control unit 5 is also input to the clock control unit 12 and the read control unit 17 to activate them.

The clock control unit 12 outputs the clock of the minimum frequency to the variable frequency oscillator 11 until the read end signal m is input from the read control unit 17. As a result, the write clock circuit 9 generates the clock g in synchronization with the synchronization signal f of the received video signal and stores it in the image storage unit 8 with the received video signal decimated to 10/30 in both the horizontal and vertical directions. It is written as image information for the child screen. Then, the read clock circuit 10 generates the clock i in synchronization with the display synchronization signal h, reads the image information from the image storage unit 8 at a speed 30/10 times as high as that at the time of writing, and the read clock circuit 10 passes through the mixing unit 18. Output to the display unit 19. Then, as shown in FIG. 4A, in the picture-in-picture state, the received image when the power is turned on is displayed on the upper right corner of the screen of the display unit 19 as the initial image on the child screen 31 having an area ratio of 1/9. To be done. At the same time, the read control unit 17 starts the read operation from the character storage unit 14 by the ON signal j from the ON / OFF control unit 5. The time determination unit 16 reads the current time from the clock 15 and determines the morning time zone, the daytime zone, or the nighttime zone. The read control unit 17 first reads the time zone of the determination result from the time determination unit 16 and starts reading one pattern drawing data of the character from the character storage unit 14 according to the determined time zone. At the same time, the recording / playback unit 20 is controlled to start reading one voice message from the recording / playback unit 20 in accordance with the determined time zone.

For example, in the morning time, as the drawing data, as shown in FIG. 4A, a character 41 and a character message 42 ("Good Morning Welcome to Amusemen") are displayed.
t TV ”) is displayed on the main screen 30, and at the same time, a voice message (“ Good morning! Mr. Yamamoto ”) and the speaker 24 are displayed.
Output from. Also, during the daytime, characters and character messages ("Go
od Afternoon Welcometo Amusement TV ") and is displayed on the main screen 30, at the same time, and outputs a voice message (" Hello! Yamamoto's ") from the speaker 24. In the night time, characters and character messages (“Good Evening
"Welcome to Amusement TV") is displayed on the parent screen 30, and at the same time, a voice message ("Good evening! Yamamoto-san") is output from the speaker 24. in this way,
The read control unit 17 sequentially reads data from the character storage unit 14 and the recording / playback unit 20 in accordance with the clock sent from the clock control unit 12 and the determination result from the time determination unit 16, and the characters on the main screen 30 The text message is changed and the voice message is output. In FIG. 4B, the character 41 is leaving the main screen 30 and the text message 42 is disappearing. During this time, the received image on the child screen 31 is changing in real time.

When the display of the character and character messages and the output of the voice message accompanying the power-on operation are completed, the read control unit 17 outputs a read end signal m to the clock control unit 12. As a result, as shown in FIG. 4C, the child screen 31 is gradually zoomed up (see the double-lined arrow) to become a full screen. That is, when the read end signal m is input, the clock control unit 12 gradually increases the frequency of the clock given to the variable frequency oscillator 11. As a result, the frequency of the clock g with which the write clock circuit 9 accesses the image storage unit 8 is sequentially increased, and the initial 10/30 to 11/30 → 12 /
30 → 13/30 → ... 30/30, while sequentially increasing the frequency, the received video signal is sampled and written into the image storage unit 8 as image information, and accordingly, the read clock circuit 10 causes the image storage unit 8 to read. The frequency of the clock i for accessing is gradually decreased, and from the initial 30/10 times to 30/11 times → 30/12 times → 30/13 times → …… 3
The image storage unit 8 while sequentially decreasing the frequency to 0/30 times
The image information is further read and output to the display unit 19 via the mixing unit 18. At this stage, the output from the character storage unit 14 to the mixing unit 18 has already been completed. As described above, the size of the small screen 31 displaying the received video is smoothly zoomed up, and finally the full screen is obtained. When the small screen 31 becomes the full screen, the clock control unit 12 outputs the zoom end signal n to the switch switching unit 13, the changeover switch 7 is switched to the contact a side, and the received image from the television receiving circuit 6 is received. The signal is directly sent from the mixing section 18 to the display section 19
Sent to. Therefore, as shown in FIG. 4D, the full screen of only the received video is displayed, and the full-scale viewing state is entered.

Next, the operation when the power is off will be described with reference to the schematic timing chart shown in FIG. Figure 5 (a)
When the power-off operation signal transmitted from the infrared remote control device is received by the remote control receiving unit 1 when the received image is displayed on the display unit 19 in the full screen state as described above,
Alternatively, when a power-off operation is performed on the operation panel unit 2, the power-off signal d is input to the power supply control unit 3, but the power supply circuit 4 is not immediately turned off, and a certain process is performed as described later. Then, the power supply circuit 4 is kept in the ON state until the read end signal e is input from the read control unit 17 to the power supply control unit 3.

The power-off signal d is also input to the on / off control section 5 to bring the on / off control section 5 into the power-off detection state. When the off signal k is output from the on / off control unit 5 to the switch switching unit 13, the switch switching unit 13
This time, the selector switch 7 is immediately switched to the contact b side, and the television receiving circuit 6 is connected to the image storage unit 8. The off signal k from the on / off control unit 5 is also input to the clock control unit 12 and the read control unit 17 to activate them.

When the clock controller 12 is activated, as shown in FIG. 5 (b), the screen state of the display unit 19 is switched from the full-screen state to the state of the maximum-area child screen 31, and then the frequency is changed. By gradually decreasing the frequency of the clock given to the variable oscillator 11, the sub-screen 3
1 is gradually zoomed down (screen reduction) (see double-lined arrow). As a result, the frequency of the clock g for the write clock circuit 9 to access the image storage unit 8 is sequentially lowered, and the initial 30/30 to 29/30 → 28/3
0 → 27/30 → ... 10/30 while sequentially decreasing the frequency and sampling the received video signal and writing it in the image storage unit 8 as image information. The frequency of the clock i for accessing is sequentially increased, and from the initial 30/30 times to 30/29 times → 30/28 times → 30/27 times → …… 3
The image information is read from the image storage unit 8 while the frequency is sequentially increased by 0/10, and is output to the display unit 19 via the mixing unit 18. As described above, the size of the small screen 31 displaying the received video is smoothly zoomed down, and when the small screen 31 is reduced in area to 1/9 of the full screen, the clock control unit 12 reads out the read control unit. The zoom end signal p is output to 17, and the read control unit 17 starts operation.

The read control unit 17 firstly determines the time determination unit 16
From this, the determination result indicating which time zone the current time is in is read, and reading of one pattern drawing data of the character from the character storage unit 14 is started in accordance with the determined time zone. At the same time, the recording / playback unit 20 is controlled to start reading one voice message from the recording / playback unit 20 in accordance with the determined time zone.

For example, in the daytime, as the drawing data, as shown in FIGS. 5C and 5D, a character 41 and a character message 42 (“THANK YOU ! by Amusement TV ”) is displayed on the main screen 30, and at the same time, a voice message (“ goodbye ”) is output from the speaker 24. Also, in the morning time zone, characters and character messages ("GOOD LUCK! B
y Amusement TV ”) is displayed on the main screen 30 and at the same time,
A voice message (“See you later!”) Is sent to the speaker 24.
Output from.

Further, in the night time zone, a character and a character message (“GOOD NIGHT! By Amusement TV”) performing another motion suitable for the night motion are displayed on the main screen 30 as drawing data, and at the same time, A voice message (“Good night”) is output from the speaker 24. In this way, the read control unit 17 sequentially reads data from the character storage unit 14 and the recording / playback unit 20 according to the clock sent from the clock control unit 12 and the determination result from the time determination unit 16, and the main screen 30 is read. Change the characters and text messages in and output voice messages. During this time, the switch 25 is turned off by the command signal q from the clock control unit 12 to erase the child screen 31, and only the character 41 and the character message 42 are displayed (FIG. 5 (d)).

When the display of the character and character messages and the output of the voice message associated with the power-off operation are completed, the read control unit 17 outputs a read end signal e to the power supply control unit 3. Since the power supply off signal d has already been input to the power supply control unit 3, the power supply circuit 4 is actually turned off by the input of the read end signal e. Therefore, the screen display on the display unit 19 is also erased.

As described above, when the power is turned on, the received program is displayed on the sub-screen, and at the same time, a character and a character message having a certain movement indicating that the viewing of the program is about to start are displayed and a voice message is displayed. When the message is output and the character and the character message disappear, the child screen smoothly zooms in and switches to a normal received program. Also, when the power is turned off, the received program is smoothly zoomed down from the full screen to the sub screen, and then a character and a text message with a certain movement indicating that the viewing of the program is finished are displayed and a voice message is displayed. A message is output and the screen display disappears immediately after that. Therefore, it is possible to create a kind of psychological unity between the television and the viewer (the feeling that the television is a companion to be with). When the power is on, for example [Come on, it ’s about to begin], [Come on,
I got a strong impression that I'm going to see it, and when I turned off the power, for example, I finished watching. It was interesting], [Well, do you want to work on your next job]?
In this way, it is possible to give viewers a certain sense of interest, feeling, and atmosphere, and it is extremely superior in terms of friendliness compared to conventional TVs. There is.

In the description of the above embodiment, the character storage unit 14 stores three types of drawing data for morning, daytime, and night, and the recording / reproducing unit 20 also stores morning, daytime, and nighttime drawing data. Although three types of voice messages are stored, the number of types of each may be more or less than this. Further, either one or both may be only one type, in which case the time determination unit 16 is unnecessary. Also, the voice message may be omitted.

[0033]

According to the television receiver of claim 1 of the present invention, when the power is turned on at the start of viewing, the television side gives a message to the viewer, for example, "welcome". ), And then the received image zooms up and feels closer to you, and since the viewer watches it when the power is turned on, it's something that can't be displayed on a conventional television receiver.・ Interesting video production is performed. As a result, the viewer feels a kind of psychological unity and expectation with the television when he / she is about to watch it, and the familiarity with the television increases.

According to the television receiver of claim 2 of the present invention, the received image is received from the viewer by zooming down the received image from the full screen to the sub-screen in accordance with the power-off operation at the end of viewing. There is a feeling that you are going away, and then a message screen appears that you will finish watching the program with this, giving the viewer a feeling that you are actually watching. This is also an interesting video production, and the viewer feels a kind of satisfaction, "I have finished watching." This was also not a conventional television receiver, I felt a sense of unity with the TV,
Television feels more familiar.

It should be noted that when a character or character message that moves in a certain manner is displayed as a message screen or a voice message is also output, a more interesting staging effect is exerted and empathy becomes stronger. .
