Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal processing apparatus suitable for selecting a channel when receiving a multi-channel broadcast.

[0002]

2. Description of the Related Art In recent years, digital broadcasting has been developed. Since digital broadcasting is multi-channel, a receiving terminal is required to have excellent operability in channel selection. For example, Japanese Unexamined Patent Application Publication No. 10-256875 proposes an improved operability of channel selection. In this proposal, a device is disclosed that measures the viewing frequency of a channel that a user has watched in the past, and automatically selects a channel according to the user's preference in association with program data.

FIG. 10 is a block diagram showing a conventional video signal processing device disclosed by this proposal.

[0004] The broadcast signal received by the receiving unit 10 is tuned by a tuning unit 11 and supplied to an output unit 12. The tuning of the tuning section 11 is controlled by the control section 20. The control such as channel selection by the control unit 20 is performed based on various setting data stored in the setting data storage unit 24. The setting data editing unit 25 includes the input unit 4
The setting data can be edited based on the user's operation.

[0005] The program data storage section 22 stores program data in which a genre, a program name, and the like for each program are associated with a broadcast time zone. The control unit 20 uses the timer 15 to access the program data storage unit 22 at predetermined time intervals to acquire program data for the currently selected channel. Then, based on the acquired information, it creates viewing frequency data indicating a user's selection history for each data type for the selected channel, and updates the viewing frequency data storage unit 23.

At the same time, the control unit 20 reads out the program data of the program currently being broadcast from the program data storage unit 22 and selects the most suitable program for the user by comparing it with the contents stored in the viewing frequency data storage unit 23. I do. Control unit 20
Controls the channel selection unit 11 to select a channel on which the selected program is broadcast. In this way, it is possible to automatically select a channel that is frequently watched by the user.

While channel selection by viewing frequency is extremely useful, users do not always want to select the channel with the highest viewing frequency. However, the conventional example of FIG. 10 has a problem that the user cannot easily recognize another channel having a relatively high viewing frequency. Further, even when a plurality of channels having relatively high viewing frequencies are displayed on the screen, there is a problem that the tuning operation is relatively complicated when the number of channels is large.

[0008]

As described above, in the above-described conventional video signal processing apparatus, a desired channel cannot be recognized from a plurality of channels having relatively high viewing frequencies, and There has been a problem that a plurality of relatively frequent channels cannot be selected by a simple operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and enables a user to visually recognize a frequently watched channel, and one-touch a frequently watched channel without performing complicated settings. It is an object of the present invention to provide a video signal processing device capable of selecting a channel by using the same.

The display control means causes one or more channels to be displayed on the small screen in a display mode according to the channel order.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of a video signal processing device according to the present invention. In FIG. 1, the same components as those in FIG. 10 are denoted by the same reference numerals.

In FIG. 1, a receiving unit 10 includes an antenna, a cable, and the like, receives a broadcast signal from each broadcasting station, and outputs a received signal to a tuning unit 11.
The tuning unit 11 is controlled by the control unit 13 to select a specific channel from the input received signals, and outputs the video and audio signals of the selected channel to the output unit 12.
The output unit 12 includes a monitor, a speaker, and the like.
3 and performs predetermined signal processing on information such as video and audio included in the signal tuned by the channel selection unit 11, and then displays the video on the display screen and outputs the audio from the speaker. Output sound.

The input unit 14 includes a remote controller, a keyboard, and the like, and outputs a signal to the control unit 13 based on a manual tuning operation by a user.
The viewing frequency data storage unit 16 is controlled by the control unit 13 to store, for one or more users, viewing frequency data indicating which channel each user has previously selected at which frequency. It has become.
The viewing frequency ranking calculation unit 17 includes a viewing frequency data storage unit 16.
The channel ranking of the viewing frequency is calculated from the viewing frequency for each channel stored in the control unit 13 and the calculation result is output to the control unit 13. The timer 15 measures time, and outputs time information indicating a day of the week, date and time, and the like to the control unit 13.

In this embodiment, a display form setting section 18 is provided. The display mode setting unit 18
Under the control of the control unit 13, the display mode of each channel is set based on the channel ranking of the viewing frequency calculated by the viewing frequency ranking calculation unit 17.

The control unit 13 controls each unit, and
, The currently selected channel is taken in, and the display mode is controlled in accordance with the setting from the display mode setting unit 18. For example, the control unit 13 can execute a frequency display automatic execution mode for displaying a program of each channel in a display mode according to the viewing frequency rank.

In the frequency display automatic execution mode, the control unit 1
3 obtains the viewing frequency of each channel in each time zone for each user by various methods by controlling the viewing frequency ranking calculation unit 17, and the viewing frequency is higher than the channel based on the user's channel selection operation. (Hereinafter referred to as high-frequency channels), these high-frequency channels can be displayed based on the viewing frequency channel ranking by, for example, a small screen display. The display in this case, that is, the display mode of the viewing frequency display is controlled by the control unit 13 and set by the display mode setting unit 18 as described above.

Note that the control unit 13 can display the viewing frequency display in the display mode set by the display mode setting unit 18 even when instructed to display the viewing frequency display based on a user operation. It has become.

Further, in the present embodiment, the input unit 1
4 is provided with a plurality of one-touch channel selection buttons for selecting an arbitrary channel from among the plurality of channels displayed by the viewing frequency display with one touch while referring to the viewing frequency display on the screen. It has become.
As the one-touch tuning button, for example, a plurality of buttons to which numbers corresponding to the viewing frequency rankings are assigned are employed.
Further, as the one-touch channel selection button, a plurality of buttons displaying colors corresponding to the viewing frequency ranking may be employed. The input unit 14 may be provided with, for example, a frequency display button for displaying a frequency display on the screen.

When the one-touch channel selection button of the input unit 14 is operated, the control unit 13 determines which channel has the channel rank of the viewing frequency corresponding to the operated number, and determines this channel. A channel selection signal for selecting the channel is output to the channel selection unit 11.

Next, the operation of the embodiment configured as described above will be described with reference to FIGS. FIG. 2 is an explanatory view showing a screen display example, and FIG. 3 is a flowchart for explaining the operation of the embodiment.

In the present embodiment, the control unit 13
Using the information on the selected channel, the viewing frequency data storage unit 16 stores information on the viewing frequency of each channel in each time zone for each user. It is assumed that the mode is the frequency display automatic execution mode, and the user operates the input unit 14 to perform a channel selection operation in step S10 of FIG.
The control unit 13 outputs a tuning signal based on a user's tuning operation to the tuning unit 11. Thereby, the program of the channel based on the user operation is selected from the received signals received by the receiving unit 10 and supplied to the output unit 12. Thus, the program selected by the user is displayed on the display screen (not shown) of the output unit 12.

On the other hand, the control unit 13 accesses the viewing frequency data storage unit 16 and updates the viewing frequency data in the viewing frequency data storage unit 16 with information based on the user's channel selection operation. That is, in step S11, the control unit 13 adds 1 to the viewing frequency in the time zone of the current time for the channel selected by the user, and stores it (step S12).

The viewing frequency data storage unit 16 outputs the viewing frequency of each channel in the time zone of the current time for the user who has performed the channel selection operation to the viewing frequency ranking calculation unit 17. In step S13, the viewing frequency ranking calculation unit 17 calculates the channel ranking of the viewing frequency of each channel in the time zone of the current time. The control unit 13 reads the information on the channel order, and determines in step S14 whether there is a channel having a channel order whose viewing frequency is higher than the channel order of the viewing frequency of the currently viewed channel.

If there is no channel whose viewing frequency is higher than that of the currently viewed channel, the process ends. That is, in this case, the currently receiving channel is continuously selected and the current display mode is continued.

If there is a channel whose viewing frequency is higher than the currently viewed channel, the control unit 13
For the channel with the highest frequency, the information on the current viewing frequency is read from the viewing frequency data storage unit 16 and output to the display mode setting unit 18. Note that the control unit 13 may supply information on the viewing frequency of all the channels to the display mode setting unit 18.

The display mode setting section 18 sets a display mode in accordance with a preset display method based on the input viewing frequency information. For example, the display mode setting unit 18
Each channel is displayed in a small screen according to the viewing frequency. In this case, the display mode setting unit 18 determines in step S
In 15, the display area of the sub-screen used for displaying each channel is calculated, and the display mode based on the calculation result is set to
Instruct 3

The control section 13 controls the tuning section 11 and the output section 12 based on the display mode set by the display mode setting section 18 to display the viewing frequency display on the screen (step S1).
6). FIG. 2 shows a display example of the display screen in this case.

In FIG. 2, a channel based on a channel selection operation of the input unit 14 by the user is displayed on the display screen 12 at the center of the screen by the main screen display 22. Also,
The sub-screen displays 23 to 27 of the higher frequency channels for the channel displayed by the main screen display 22 are displayed on the right side of the display screen 12 with an area corresponding to the channel order. The small-screen display 23 indicates that the user has selected the channel most recently in the current time zone. Similarly, the child screen display 27 indicates that the channel having the lowest viewing frequency among the channels having a higher viewing frequency than the channel displayed by the main screen display 22.

Note that the display determination setting unit 18 may display all of the higher frequency channels in the sub-screen, or may display only a predetermined number of sub-screens in order from the highest channel order.

Here, it is assumed that the user desires to select a channel having the second highest viewing frequency in the past. In this case, the user presses, for example, a button assigned a numeral 2 indicating that the viewing frequency is the second among the one-touch tuning buttons provided on the input unit 14. The signal based on this user operation is supplied to the control unit 13, and the control unit 13 performs, based on the information stored in the viewing frequency data storage unit 16,
The channel displayed on the small screen display 24 is determined, and a channel selection signal for receiving the channel is output to the channel selection unit 11. In this way, the channel with the second viewing frequency is selected, and the output unit 12 displays, for example, the entire screen.

As described above, in the present embodiment, the viewing frequency of each channel in each time zone of each user is stored and updated according to the channel selection operation, and the ranking of the viewing frequency is calculated. When there is a channel whose viewing frequency is higher than the currently selected channel, by adopting a visually easy-to-recognize display method of displaying a small screen with an area according to the ranking of viewing frequency, It is possible to easily confirm not only the channel with the highest frequency but also the channel with the highest viewing frequency along with its rank. In addition, one-touch tuning can be performed by a tuning operation corresponding to the order of the viewing frequency without being conscious of the number of the channel desired to be tuned, and the operability is excellent. For this reason, it is extremely useful for a channel selection operation in the case of multi-channeling.

FIG. 4 is a flowchart showing an operation flow employed in another embodiment of the present invention. In FIG. 4, the same steps as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

This embodiment differs from the embodiment of FIG. 1 only in the processing of the control unit, that is, the method of generating frequency data, and can be realized by the hardware configuration of FIG.

FIG. 4 differs from FIG. 3 in that step S21 is inserted between steps S10 and S11. Step S21 is a procedure for determining whether or not the current viewing channel has been viewed for a certain period of time or longer. If it is determined in step S21 that the viewing channel has not been viewed for a certain period of time or more, the process ends.
If it is determined that the viewing channel has been viewed for a certain period of time or longer, the process proceeds to step S11, and the viewing frequency is incremented.

In the embodiment configured as described above, the method of obtaining the viewing frequency is different from that of the embodiment of FIG. 1 so that the viewing frequency is not incremented only by the user's channel selection operation. That is, when the user performs a tuning operation in step S10,
In the next step S21, it is determined whether or not the viewing channel has been viewed for a predetermined time or more.

In this case, the control unit 13
It is determined whether or not the channel selection and display of the viewing channel have been performed in the channel selection unit 11 and the output unit 12 for a predetermined time or more using the time information from If the channel has been selected and displayed for a predetermined time or longer, the control unit 13 determines that this channel has been viewed and proceeds to the next step S
At 11, the viewing frequency data storage unit 12 is controlled to increment the viewing frequency.

The control unit 13 determines whether or not the viewing time of the previous viewing channel, which was being viewed by the user before the channel selection operation, is longer than a certain time.
It may be determined whether or not the previous viewing channel has been viewed. In this case, in step S11, the viewing frequency is incremented by the previous viewing.

If it is determined that the selected channel has not been viewed for a predetermined time or longer, the control unit 13 ends the processing without updating the viewing frequency. Therefore, for example, when the user selects a channel at random to check the broadcast content, the viewing frequency is not updated. That is, only when the user is willing to view the channel, the viewing frequency of the channel is updated, so that control according to the user's request can be further performed.

FIG. 5 is a flowchart showing an operation flow employed in another embodiment of the present invention. 5, the same steps as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

This embodiment differs from the embodiment of FIG. 1 only in the processing of the control unit, and can be realized by the hardware configuration of FIG. In the present embodiment, the viewing frequency is obtained not by the number of times of channel selection but by the channel selection time.

In FIG. 5, steps S31 and S32 are provided in place of step S11 in FIG. 3, and step S33 is provided in place of step S13. Step S31 is a procedure for measuring the previous viewing channel time, and step S32 is a procedure for cumulatively adding the measured viewing time to the viewing time in the corresponding time zone of each channel for each user.

In the embodiment configured as described above, the method of obtaining the viewing frequency is different from that of the embodiment shown in FIG. 1 in that the viewing frequency is obtained based on the viewing time of the channel selected by the user. That is, step S
When the user performs a channel selection operation in 10, the control unit 13 measures the viewing time of the previously viewed channel that has been viewed up to that time based on the information from the timer 15 in the next step S31. The control unit 13 accesses the viewing frequency data storage unit 16 in step S32,
The measured time is cumulatively added to the viewing time of the corresponding time zone for the same channel as the previous viewing channel, and stored (step S12).

In the next step S33, the viewing frequency ranking calculation unit 17 reads out the information stored in the viewing frequency data storage unit 16 and determines the viewing frequency ranking for each channel for each time zone for each user. calculate.

Other functions are the same as those of the embodiment shown in FIG. The viewing frequency ranking calculating unit 17 may calculate the viewing frequency using a time zone different from the time zone used for the calculation in the embodiment of FIG.

As described above, in the present embodiment, the same effect as in the embodiment of FIG. 1 can be obtained by storing the viewing frequency data associated with the viewing time.

Further, when measuring the viewing frequency data, the day and time data output from the timer 15 are added to the viewing frequency data, and the viewing frequency ranking according to the currently viewed day and time is calculated. It may be displayed. Thereby, the viewing frequency corresponding to the time zone and the day of the week can be recognized.

FIG. 6 is an explanatory diagram showing a screen display in a channel search mode employed in another embodiment of the present invention.

This embodiment is applied to a channel search function by multi-channel display, and can be realized by the hardware configuration of FIG.

This embodiment is different from the embodiment of FIG. 1 only in the setting of the screen display by the display mode setting section 18 in the channel search mode. As shown in FIG. 6, in the channel search mode, a plurality of small-screen displays 29 having different sizes are displayed on the display screen 21.

The control unit 13 reads out the information of the channel order of the viewing frequency from the viewing frequency order calculating unit 17 and gives it to the display mode setting unit 18. The display mode setting unit 18 calculates the display area according to the channel order of the viewing frequency, and allocates a larger display area as the channel order is higher. In the channel search mode, the display mode setting unit 18 sets a display mode for displaying a small screen from the top of the channel order to a predetermined number of channel orders over the entire screen with the allocated display area.

In the channel search mode, the control unit 13 controls the channel selection unit 11 and the output unit 12 so as to display a screen in the display mode specified by the display mode setting unit 18. The control unit 13 supplies the information on the channel ranking of the viewing frequency to the display mode setting unit 18 at an appropriate time interval, so that the display mode of the channel search mode is displayed regardless of the designation of the channel search mode. By performing the setting process for this, it is possible to display the screen in the search mode at high speed. Further, in this case, when the viewing frequency order is not changed, the display setting process is omitted, so that useless processing is omitted.

Next, the operation of the embodiment configured as described above will be described with reference to the flowchart of FIG. 7, the same steps as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

The flowchart of FIG. 7 differs from the flowchart of FIG. 3 in that steps S41 to S45 are added. The processing from step S10 to step S16 is
This is the same as the operation flow of FIG. In the present embodiment, steps S41 to S45 for the channel search mode processing are executed following the processing of step S16.

In step S41, it is determined whether or not the viewing frequency ranking has been changed. If the viewing frequency order has been changed, a display area calculation process for displaying a small screen in the channel search mode is performed in step S42 based on the changed viewing frequency order. If there is a child screen whose display area has been changed, processing for moving the display position is performed (step S43).

In the next step S44, it is determined whether or not the channel search mode has been designated by a user operation. If not, the process ends without changing the display mode up to step S16. When the channel search mode is designated, steps S42, S43
The setting for displaying the screen in the display mode of the channel search mode set by the above is supplied to the control unit 13 (step S45).

FIG. 6 shows a screen of the channel search mode in this case. In the example of FIG. 6, for the eight channels with the highest viewing frequency, a small screen is displayed on the upper side of the display screen 21 with a relatively large area. For the 16 channels from 9th to 24th viewing frequency, a small screen is displayed with a size of 1/4 of the top 8 channels. For the 16 channels from 25th to 41st viewing frequency, the top 8 channels are displayed. The child screen is displayed in a size of 1/16.

Now, for example, it is assumed that the user wants to view a program whose viewing frequency is the third. In this case, the user presses, for example, a button to which the number 3 is attached, which indicates that the viewing frequency is the third among the one-touch tuning buttons of the input unit 14. A signal based on this operation is supplied to the control unit 13, and the control unit 13 selects a channel selection signal for selecting a program displayed third from the left at the upper end of the screen based on the input signal. Output to local unit 11. Thus, on the display screen 21 of the output unit 12, the program having the third viewing frequency is displayed on the entire screen.

As described above, in the present embodiment, the same effects as in the embodiment of FIG. 1 can be obtained, and in the channel search mode, the channel having a high viewing frequency is preferentially displayed with a large display area. Can be
More channels can be displayed than when each channel is displayed in the same area. When the viewing frequency order is not changed, the display area calculation processing and the display position moving processing are omitted, and the processing for the search mode can be reduced.

FIG. 8 is an explanatory view showing a screen display in a channel search mode employed in another embodiment of the present invention.

This embodiment is also applied to the channel search function by multi-channel display, and can be realized by the hardware configuration of FIG.

This embodiment is different from the embodiment of FIG. 1 only in the setting of the screen display by the display mode setting section 18 in the channel search mode. As shown in FIG. 8, in the channel search mode, a plurality of small screen displays 30 having the same size are displayed on the display screen 21.

The control unit 13 reads out the information on the channel order of the viewing frequency from the viewing frequency order calculating unit 17 and gives it to the display mode setting unit 18. The display mode setting unit 18 assigns colors according to the channel ranking of the viewing frequency. In the channel search mode, the display mode setting unit 18 assigns predetermined colors in order from the top of the channel order, and sets a display mode for performing display using the assigned colors as a frame for the sub-screen display.

In the channel search mode, the control unit 13 controls the channel selection unit 11 and the output unit 12 so as to display a screen in the display mode specified by the display mode setting unit 18.

Next, the operation of the embodiment configured as described above will be described with reference to the flowchart of FIG. In FIG. 9, the same steps as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

The flowchart of FIG. 9 differs from the flowchart of FIG. 3 in that steps S50 and S51 are added. The processing from step S10 to step S16 is the same as the operation flow in FIG. In the present embodiment, steps S50 and S51 for the channel search mode processing are executed following the processing of step S16.

In step S50, it is determined whether or not the channel search mode has been designated by a user operation. If not, the process ends without changing the display mode up to step S16. When the channel search mode is designated, the process moves to step S51.

In step S51, the display mode setting section 18 makes settings for displaying a sub-screen display framed in a color indicating the channel order. The control unit 13 displays a small screen in the channel search mode based on the setting.

FIG. 8 shows a screen of the channel search mode in this case. In the example of FIG. 8, the images of the 16 channels with the highest channel order are displayed on the screen in a small screen. The child screen displays 31 to 33 are red,
It is framed in blue and green. This indicates, for example, that the channel order is higher in the order of the child screen displays 31 to 33.

In the example shown in FIG. 8, the other sub-screen displays other than the sub-screen displays 31 to 33 display programs having relatively low channel rankings. It is not colored or has a black outline.

Now, it is assumed that the user wants to view the program displayed on the child screen display 31. In this case,
The user presses a button colored in red among the one-touch tuning buttons of the input unit 14. A signal based on this operation is supplied to the control unit 13, and the control unit 13 sends a tuning signal for tuning a channel displayed on the small screen display 31 to the tuning unit 11 based on the input signal. Output. Thus, on the display screen 21 of the output unit 12,
The program displayed by the small screen display 31 is displayed on the entire screen.

As described above, also in this embodiment, FIG.
The same effect as that of the embodiment can be obtained. In addition, since the color of the button provided for one-touch channel selection matches the color of the frame of the small-screen display assigned as the higher-frequency channel, the visual channel selection operation can be further performed.

The present invention is not limited to the above embodiments, and various applications are possible. For example,
The method of measuring the viewing frequency can be freely selected regardless of the display mode. It is clear that the display modes of FIGS. 6 and 8 can be applied to modes other than the channel search mode.

[0074]

As described above, according to the present invention, it is possible to visually recognize a frequently watched channel, and to select a frequently watched channel with one touch without performing complicated settings. This has the effect of making it possible to
