Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV receiver, and more particularly to a TV receiver capable of obtaining advice information suitable for an individual's lifestyle.

[0002]

2. Description of the Related Art Today's TV receivers are used not only for general UHF broadcasting stations but also for BS broadcasting, VTRs, laser discs, or teletext monitor screens. Operations that match the style are often performed. For example, in the early morning, people who watch station A's educational program every certain day of the week, and at night people who watch document programs broadcast on station C's specific day following station B's specific news program without hesitation. In other words, the broadcast programs viewed in a certain time period tend to be fixed every weekday depending on the lifestyle of the individual.

[0003]

By the way, even a person having such a lifestyle, after turning on the TV receiver, watches the recorded video until the program his or her favorite starts. Or, when watching a sports program or the like of another broadcasting station, there is a case that the program I watch at any time is overlooked. In such a case, if the timer recording operation is performed, the problem of overlooking the scheduled program can be solved, but the timer recording is generally troublesome to operate, and there is a tendency that it is not used unless it is a very important program. ..

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and, for example, selects a broadcast channel selected in the control unit of a TV receiver with each day of the week and time as parameters. A calculation unit that constantly calculates the frequency and a weekly tuning information storage unit that sets and stores programs that have a high probability of being selected at a specific time on each day from the results of this calculation unit are provided. Compare the output data of the station information storage means with the broadcast channel currently selected,
When the comparison results do not match, the advice is output to the user immediately before or after the start of the broadcast.

[0005]

In the memory in the control unit, the broadcasting channels which the viewers are likely to watch on a daily basis are stored as channel selection information, and this information is constantly compared with the currently selected channel. If, at a certain time, the tuning information data does not match the selected broadcasting channel, it means that the viewer has forgotten to select the desired broadcasting. It is possible to notify that the broadcast starts.

1 is a block diagram of a TV receiver according to the present invention, in which 1 is a tuner for selecting a broadcasting station, 2 is an intermediate frequency amplifier, and 3 is a demodulated video signal processing circuit. As shown, various processes such as color signal separation, color difference signal formation, and synchronization signal extraction are performed, and RGB signals are supplied to a CRT (CRT) 4 for visualization. Reference numeral 5 denotes a control unit for outputting a control signal to each of the functional circuits. The control unit 5 broadcasts based on an operation signal of the remote controller 8 input from the input key switch (operation button) 6 or the light receiver 7. Performs station selection, volume up / down, and various image quality controls. Reference numeral 9 denotes a character (graphic) generator for superimposing and outputting various kinds of information on the display screen, and this character generator 9 shows the operation contents when the control data is output from the control section 5. , It has a function to project characters.

Further, it is also possible to insert an image for displaying an external video signal, a BS video signal, etc. input to the video signal processing circuit 3 on a parent-child screen. Inside the control unit 5 of the present invention, a CPU, a RAM,
A timer circuit TC is provided outside the semiconductor memory such as a ROM so that time management is performed on a weekly basis.
Then, based on this time management, as described later, T
The tuning information of the V receiver is stored in the weekly tuning information storage unit (WTT). Incidentally, 10 is a voice generator, 11 is an amplifier, and 12 is a speaker, which are used when outputting the advice information by voice. The TV receiver of the present invention is provided with each of the above-mentioned circuit blocks so that, for example, the remote controller 8 can be operated in the same manner as a normal TV receiver.
Turns on / off the power, selects the broadcasting station, and adjusts the volume.

By the way, in the TV receiver of the present invention, when it is determined that a broadcasting station has been selected to be in the viewing state, the viewing state is what day of the week, which broadcasting station was selected. It is configured such that a broadcasting station that is often seen in normal daily life can be stored in the weekly channel selection information storage section based on the totalized data sequentially calculated by the calculation section. That is, as shown in the flowchart of FIG. 2, when the TV receiver is in operation, the control unit takes in the current day of the week data and time data from the timing circuit and determines whether or not there is a channel selection. (F10) Then, if there is a channel selection, it is determined whether or not m minutes have elapsed, and when a predetermined time has elapsed, it is regarded as the viewing state of this channel, and the channel number and the current time are stored in the memory. .. (F12) Then, the frequency is totaled using the day of the week, the time, and the selected channel as parameters. (F13) Also,
It is possible to store the volume in the viewing state at the same time and add the volume level as data together with the broadcast channel.

Therefore, this aggregated data is the T of the present invention.
It can be considered that the user of the V receiver mainly expresses his or her lifestyle, that is, what programs he or she often watches every day. In addition, the result of this aggregation, for example, that the frequency of channel selection using the day of the week and time as a parameter is determined to be relatively high with respect to other channel selection is stored in the weekly channel selection information storage unit. For example, people who always watch shogi games from 10:00 am on Sunday morning, and people who watch the document program of broadcasting station A at 8:00 pm on Monday, are the frequencies at which the corresponding broadcasting channel is selected by the remote control etc. Is about 4 to 10 times higher than the selection frequency of other broadcast channels, and this selection information is stored in the weekly channel selection information storage unit. Therefore, the weekly channel selection information storage unit is stored in the area stored for each day of the week as data in the direction of increasing frequency with the broadcast channel number and time as addresses, for example, as shown in FIG.
The data whose height direction data is equal to or larger than the predetermined value is stored.

Further, in the TV receiver of the present invention, as shown in FIG. 4, when the broadcast channel information stored in the weekly channel selection information storage unit reaches a predetermined time (F21) on a certain day of the week. The registered broadcast channel number is read, and the read broadcast channel number is compared with the currently selected channel. (F22) If the above two channel numbers do not match,
For example, the current time and the registered broadcast channel are displayed in the corner of the screen (F23) (may be blinking), and then the message is cleared (F24). Therefore, when the user is watching another broadcast program differently at any time, if the broadcast program that he or she often sees is output from the weekly channel selection information storage unit, the above-mentioned advice message is displayed on the TV.
By being displayed on the screen, it is possible to know that the broadcast program that the user is watching well has started, and it is possible to prevent the program from being overlooked. Even when the power is turned off during the external input state (during video playback), the comparison result is regarded as inconsistent and the advice information as described above is given. Especially, when the power is turned off, If it is not, rather than turning on the power and displaying the advice information on the screen, only the audio circuit shown in FIG. You may choose to have a voice message saying "It's 9 o'clock. NHK news will start." Further, it is desirable that the channel output when the TV receiver is first turned on is controlled to be the broadcast channel registered in the weekly selection information storage unit.

[0011]

As described above, in the TV receiver of the present invention, in a normal use state, the viewing tendency of the person himself / herself is checked in units of one week, and the viewing / listening program he / she prefers is selected as weekly tuning information. While being stored in the storage unit,
The broadcast channel program registered in this weekly channel selection information storage unit and the current channel selection program are compared using the days of the week and the time zone as parameters, and advance notice information is output only when they do not match. Therefore, it is possible to prevent the failure of inadvertently overlooking a necessary program or a serial drama of interest that the person habitually watches.
