Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an improvement of a receiving device for reservation registration of a television program.

[Conventional technology]

Conventional methods for reserving a desired program on a television receiver (television receiver, VTR, etc.) include a program reservation method and a menu selection method (or table of contents selection method).

In the former program reservation method, the channel number of the desired program, the start time of the program, the broadcast time (or recording time)
Etc. are input by key operation and the program is reserved and registered.
Therefore, this method requires a plurality of key operations.

The latter menu selection method will be described with reference to the drawings. Sixth
The figure is a block diagram illustrating a menu selection method. In this method, a menu screen (broadcast program list) in which program names to be broadcast at a predetermined time are listed is prepared in advance.
When the viewer presses a numeral key of the channel selection unit 10, for example, "1" to specify the channel 1 station, the menu screen of the channel 1 station is called and displayed on the display unit 18.

As shown in the figure, since the broadcast program names on this menu screen are each assigned a number, the program is reserved and registered by the viewer inputting a number corresponding to the desired program.

For example, when the viewer wants to make a reservation registration of "news", he first presses the "reserve button" and then the numeral key "1" of the ten-key pad 24 to make a reservation registration of the "news" program. The number of key operations in this method is also plural.

As means for the viewer to know the broadcast program information, there are television program guides or advertisements in newspapers and magazines and television broadcast program announcements. As the latter program preview method, in many cases, the program preview video is spotlighted between the end of each program broadcast or during the broadcast of a program such as a drama.

[Problems to be solved by the invention]

As is apparent from the above, when the program preview video is viewed and the program is reserved and registered in the television receiver, it is difficult to immediately register because the conventional reservation method requires a plurality of key operations. There was a problem.

[Means for solving problems]

FIG. 1 is a block diagram of the principle of the present invention. The present invention has a receiving antenna 6, a tuner 12, a display unit 18, a channel selecting means 37, and a time measuring means 38, and when the time measuring means 38 reaches a reserved information value (time), the television signal 7 In the television receiving device for starting reception, means for receiving a television signal 7 in which a video signal of the program preview video 1 and a control signal 41 including time information 40 indicating the start of the broadcast of the preview program are incorporated, The control signal extracting means 15 for extracting the control signal 41 from the received television signal 7 and the information (for example, the time information 40) of the extracted control signal 41 having the temporary storage unit 16 are at least recorded in the program preview video 1. During the time displayed on the display unit 18, an information holding unit 39 for storing and holding the temporary storage unit 16, a reservation button (or key) 2 for reserving a program, and a storage unit 21 for storing information of a control signal 41. And make a reservation When second depressing, the information stored and held in the temporary storage unit 16, and a control unit 42 which allowed to store in the storage unit 21.

[Action]

Television signal 7 received by the receiving antenna 6.
While the program preview image 1 is being displayed on the display unit 18, the information (for example, the time information 40) of the control signal 41 extracted from the television signal 7 is stored and held in the temporary storage unit 16, and the reservation button 2 is pressed. When the button is pressed, the information (for example, time information 40) in the temporary storage unit 16 is stored in the storage unit 21, and the program predicted by the program preview video 1 is reserved and registered.

〔Example〕

The present invention will be described below with reference to the drawings. FIG. 2 is a block diagram illustrating an embodiment of the present invention, FIG. 3 is a display example illustrating an embodiment of the present invention, and FIG. 4 is a signal waveform diagram illustrating an embodiment of the present invention. FIG. 5 is a time chart explaining an embodiment of the present invention.

FIG. 2 shows an embodiment of a television receiver provided with a program reservation means, and an audio circuit and the like are omitted. According to the present invention, as shown in FIG. 3 (a), when the viewer presses the reservation button (the button to reserve a program) 2 while the program preview image 1 is displayed on the display unit 18, the preview is announced. Another program, that is, the program "Spring Sea" scheduled to be broadcast at 10:00 on January 2 (Tuesday) is pre-registered. When the reservation registration is completed, the character "Please press the reservation button" in the response field 3 disappears, and the character "Reserved" appears instead as shown in FIG. 3 (b).

As described above, the program preview image 1 is composed of image information 4 (for example, a scene of a drama) 4 that clearly shows the content of the program,
The broadcast date / time information 5 and the character information in the response field 3 also form part of the image information 4. As described above, the present invention has means for immediately preserving and registering the program on the date and time when the viewer notices the program announcement by simply pressing the advance button 2.

FIG. 4 is a signal waveform diagram showing an embodiment of a signal in the vertical blanking period of a television signal. In the vertical blanking period T, the vertical sync signal V and the horizontal sync signal are the same as in the conventional case.
HS and an equivalent pulse E are provided. Further, in this embodiment, the control signal 41 is provided after the vertical synchronizing signal V. The control signal 41 includes time information 40 including time data indicating the broadcast start time of the program, and the temporary storage unit 16
And a clear control signal Z for clearing the information of.
In addition to this, the channel number data of the program is added to the control signal 41 as needed.

In FIG. 2, from the receiving antenna 6, a television signal 7 including the control signal 41 shown in FIG.
Is received. The channel selection circuit 8 has a channel switching unit that enables reception of a television signal of a television station according to the channel number information N set in the register (temporary storage unit) 9. For example, the numeric keys of the channel selector 10
When 11 (“1”) is pressed, the channel number data N1 is set in the register 9. Along with this, the channel selection circuit 8 controls the tuner 12 so that it can receive the television signal of the television station having the channel number "1". Note that S1 is a set pulse.

As described above, the time information 40 and the clear control signal Z are sent as the control signal 41. This will be described with reference to FIG. FIG. 5 (a) shows a vertical television signal, showing the time.
The time M from t1 to tn is the time when the video signal VD (not shown) of the program preview video 1 is sent. The time information 40 is also sent within the time M as shown in FIG. Therefore, the time information 40 is sent in synchronization with the program preview video 1. Further, the clear control signal Z is sent at the time immediately before and immediately after the time M as shown in FIG. 5 (b).

The time information 40 is date and time data A and B indicating the broadcast start date and time (A day B hour) of the program announced by the program announcement image 1. Broadcast (or recording) time data D is also added if necessary. In the embodiment, broadcast time data D is also included. The "minute" unit of the date and time data is omitted.

Of the television signal 7 that has passed through the tuner 12 and the IF / detection circuit 13, the video signal is sent to the video amplification circuit 14, while the control signal 41 is extracted by the control signal extraction circuit 15.
Be discriminated against. When the video signal is the video signal VD for previewing the program, the program preview video 1 is displayed on the display unit 18.

When the extracted control signal 41 is the time information 40, the control signal extraction circuit 15 sets this in the register (temporary storage unit) 16. That is, the date and time data A and B and the broadcast time data D are set in the register 16. Therefore, at the same time that the program preview image 1 is displayed on the display unit 18, the register 16 stores the date and time data A and B indicating the broadcast start time of the program.
And the broadcast time data D are stored and held.

As is well known, in the NTSC system, the vertical blanking period is 60 times per second, so the display time of the program preview image 1 is at least 1
If there is a second, the time information 40 can be sent and received. If it is still insufficient, the time information 40 is incorporated in the television signal of the time before the program announcement time M, for example (the vertical blanking period of the television signal of the drama broadcast), and this is set. Control signal extraction circuit 15 extracts in advance and registers
It can also be stored in 16. So in this case,
When the program preview image 1 is shown on the screen after the drama ends, the register 16 already stores the date and time data A, which is related to the program preview.
B and broadcast time data D are set.

Due to the video signal VD of the program preview video 1,
Image information 4 and scheduled broadcast date information 5 as shown in FIG.
Is displayed. Needless to say, this scheduled broadcast date information 5
Is display information corresponding to the date and time data A and B in the register 16.

When the viewer who views the program preview video 1 presses the reservation button 2, the control pulse R generated by the control unit 42 is sent to the register 20, the storage unit (for example, register) 21 and the control unit 22. By this control pulse R, the register 20
Is the channel number data set in register 9,
For example, N1 is transferred and set. On the other hand, the storage unit 21 stores the data in the register 16, that is, the date and time data A and B and the broadcast time data D. Therefore, the program preview video 1
This means that the program announced in advance has been registered for reservation.

On the other hand, the control unit 22 activated by the control pulse R sends the reservation registration completion message (that is, the message “reserved”) information 25 to the synthesis circuit 26. Synthesis circuit
In the video signal VD from the video amplifier circuit 14 (the program preview video 1) VD, 26 deletes the message in the response field 3 (that is, "please press the reservation button") and replaces it with "reserved".
A new video signal V that incorporates the registration completion message
D ′ is combined and sent to the display control unit 17. As a result, as shown in FIGS. 3 (a) and 3 (b), the message display in the response field 3 on the screen of the display unit 18 is updated from "please press the reservation button" to "reserved". It

The clock counter 27 uses the pulse generator 28 to generate the clock pulse 23.
It is a counter that is driven by and always operates. That is, the count value H of the clock counter 27 is the month of a calendar day (calendar),
It indicates the day, hour, and minute.

When the count value H of the clock counter 27 matches the date and time data A and B (A day B hour) in the storage unit 21, the control unit 22
Opens the gate portion 29 and emits a control pulse 30. Along with this, the counter 31 starts its operation by the clock pulse 23. On the other hand, the control pulse 30 is sent to the register 9 and the switch unit 32. Therefore, the channel number data N1 reserved and registered in the register 20 is transferred to and set in the register 9. Along with this, the channel selection circuit 8 switches the channel to the television station (channel 1 station) with the station number "1" according to the channel number data N1.

On the other hand, the control pulse 30 supplied to the switch unit 32 turns on the switch SW. This enables the power supply for the TV receiver.
33 is turned on. If the power supply 33 is already in operation,
That state is maintained. The other power supply unit 36 is a control (digital logic circuit) power supply (a power supply for holding a battery or the like) other than the television receiving circuit.

On the other hand, when the count value G of the counter 31 and the broadcast time data (indicating broadcast time) D in the storage unit 21 match, the control unit 34 issues a control pulse C to switch the switch SW of the switch unit 32.
When it is turned off, the power supply unit 33 is cut off, that is, the reception is cut off.

Referring again to FIG. 5, the time relationship of the above control operation will be described. As described above, FIG. 5A shows the vertical television signal of the television signal 7. The time M from the time t1 to the time tn is the display time of the program preview video 1. In other words, the video signal sent between the field signals F1 to Fn.
By the VD (not shown), the program preview image 1 is displayed on the display unit 18 in FIG. 2 as shown in FIG. 5 (d).

FIG. 5B shows the time relationship between the time information 40 and the clear control signal Z incorporated as the control signal 41. After the register 16 in FIG. 2 is cleared at time t1 by the first clear control signal Z immediately before time M,
The time information 40 extracted after t2, that is, the date / time data A and B and the broadcast time data D is stored in the register 16. FIG. 5 (c) shows the data holding state of the register 16.
The register 16 is cleared by the next clear control signal Z at time tn + 1, which will be described later.

FIG. 5D shows the time when the program preview video 1 is displayed, that is, the time when the program is previewed. Therefore, the viewer may reserve the program by pressing the reservation button 2 within this time (t1 to tn-1). In FIG. 5, for example, when the reservation button 2 in FIG. 2 is pressed at time t3, the data A, B and D in the register 16 shown in FIG. 5 (c) are changed as shown in FIG. 5 (e). It is stored in the storage unit 21, and the reservation registration is completed.

As shown in FIG. 5B, when the second clear control signal Z sent during the vertical blanking period T of the field signal Fn + 1 is detected, at time tn + 1, FIG.
The data A, B and D in the register 16 shown in are cleared.
This will be described again with reference to FIG.

In FIG. 2, when the control signal 41 extracted by the control signal extraction circuit 15 is the clear control signal Z, the identification unit 35 that identifies this issues the clear signal CL and registers it.
Clear 16 Therefore, it is possible to always set the time information 40 corresponding to the program preview video 1 displayed on the display unit 18 in the register 16.

The above is the case of the program announcement of the same channel. For example, in the case of broadcasting the program of the first channel and the program announcement of the third channel, the channel number of the third channel is included in the control signal 41 from the transmitting side. The data N3 may be included and transmitted. In this case, the channel number data N3 included in the control signal 41 extracted by the control signal extraction circuit 15 in FIG. 2 is set in the register 16 (the portion indicated by the broken line). When this channel number data (N3) is being sent, this channel number data (N3) is sent to the channel number data (N1) in the register 9 when the reservation button 2 is pressed.
The control for setting the register 20 is performed in priority to the.

As described above, even in the case of a program announcement for a station other than the same channel number station, the viewer can immediately perform the reservation registration of the desired program by simply pressing the reservation button 2 in the present invention.

In particular, if the reservation button 2 shown in FIG. 2 or 3 is incorporated in the remote control pad for channel switching, when the program preview image 1 displayed on the cathode-ray tube is viewed, the operation of the remote control pad that is handed ( A program can be easily reserved only by pressing the reservation button 2.

〔The invention's effect〕

 The present invention has the following advantages.

(A) When a program preview is seen on the TV screen, the program can be immediately reserved and registered.

(B) As the reservation means, it is only necessary to press the reservation button, and it is not necessary to press the numeric keys or the like.

(C) Therefore, it is possible to make a reservation registration in the case of a program notice that flows in a spot manner.

(D) Only a reflexive operation from visual is sufficient.

(E) Since the reservation completion message (reserved) is displayed on the screen when the reservation button is pressed, it is easy to confirm the reservation and no reservation error occurs.

(F) Since it is only necessary to press the reservation button on the remote control pad when the program preview screen is viewed, it is possible to make a reservation at a location away from the receiving device.
