Abstract

PROBLEM TO BE SOLVED: To improve operation function of a user with less storage capacity by storing the history of channels which the user selects in a storage device of a predetermined capacity in accordance with an algorithm and displaying the list of the channels which are frequently viewed and/or automatically selecting a station. SOLUTION: The storage capacity of a storage device 4 is set to be of four channels, and the number of storing times for each channel is set to be three bits-eight times. When a channel A without stored data is selected, a storage content updating means 5 substitutes the channel A for a channel B with the lowest priority. Furthermore, when the channel A is selected, its priority is ranked to be higher than channels with similar number of selection times and a display/station selection control means 2 displays the list of channels on a screen. When a channel C whose number of selection times reaches the restricted number of times '8', the number of times for all channels is reduced by one time and a case occurs when the display/station selection control means 2 automatically selects the station. Then, the channel C is displayed.

JP-A-2-119307 or JP-A-3-21
As disclosed in JP-A-4919 / 1992, JP-A-4-162242 or JP-A-4-207718, a program with the highest viewing frequency is automatically selected.

[0003] As shown in Japanese Patent Application Laid-Open No. 4-294695, a list of frequently viewed programs is displayed.

[0004]

In order to select a channel having a high viewing frequency, it is necessary to store all viewing histories for all channels. When the number of channels is enormous or when the viewing history is accumulated and stored in proportion to the passage of time, the capacity of the storage device needs to be expanded without limit.

[0005]

In order to solve the above-mentioned problems, a television receiver of the present invention comprises a storage device having a fixed capacity for recording the number and the number of channels selected by a user, Storage update means for updating the record in the storage device to display a list of channels frequently viewed by the user and automatically select a channel most frequently viewed by the user.

According to the present invention, even when the capacity of a storage device is limited, a function of efficiently storing the number and the number of channels selected by a user, displaying a list of frequently viewed channels, and automatically selecting a channel is provided. it can.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the first aspect of the present invention, the history of a channel selected by a user is stored in a storage device having a fixed capacity according to an algorithm, and a list of frequently viewed channels is displayed or automatically selected. This has the effect of improving the user's operation functions.

According to a second aspect of the present invention, there is provided a storage device having a fixed capacity for recording a channel number and the number of times of a channel selected by a user, and a storage content updating means for updating a record in the storage device according to a user's selection. , A display means for displaying a list of channels, which has an effect of displaying a list of channels frequently viewed by the user.

According to a third aspect of the present invention, there is provided a storage device having a fixed capacity for recording the number and frequency of a channel selected by a user, and a storage content updating means for updating a record in the storage device in accordance with a user's selection. This has the effect of automatically selecting the channel most often viewed by the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a television receiver according to an embodiment of the present invention will be described with reference to FIGS.

(Embodiment 1) FIG. 1 is a block diagram of a television receiver according to an embodiment of the present invention. FIG.
1, the television receiver 1 comprises a display / tuning control means 2, a tuning device 3, a storage device 4, a storage content updating means 5, and a display 6.

FIG. 2 is a transition diagram of storage contents in the storage device updated by the selection of a channel in the first embodiment. FIG. 3 is an on-screen display of a list of channels frequently viewed by the user in the first and second embodiments. FIG. 4 is an on-screen transition diagram in the case where the channel most frequently viewed by the user in the first and second embodiments is automatically selected.

In FIG. 2, the storage capacity of the storage device 4 is limited, for example, for four channels, and the higher the channel in the table, the higher the priority.

The number of times that data can be stored for each channel is limited, and is limited to, for example, 3 bits, that is, up to 8 times.

The storage content updating means 5 updates the content of the storage device 4 by the following algorithm.

First, when the channel 600 is selected in the state 1, since the channel 600 is not in the storage device, the channel 600 is replaced with the channel 300 having the lowest priority. Next, in the state 2, when the channel 600 is further selected twice, the channel 600 and the channel 2 are selected.
Since the number of times of 00 is the same, the priority of the channel 600 that has been accessed most recently is raised above that of the channel 200.

FIG. 3 is an on-screen display diagram showing a case where a list of channels frequently viewed by the user is displayed by the display / tuning control means 2 at this time.

In FIG. 3, the number of channels to be displayed and displayed is a fixed number, for example, the upper three channels are displayed.

Next, when the channel 700 is selected in the state 3, the number of times is nine, and the number of all channels is decreased by one because the number exceeds the limit. FIG. 4 is an on-screen transition diagram showing a power-on state when the display / tuning control means 2 automatically tunes the channel most frequently viewed by the user.

(Embodiment 2) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a transition diagram of stored contents in the storage device updated by selecting a channel in the second embodiment.

FIG. 3 is an on-screen display of a list of channels frequently viewed by the user in the first and second embodiments. FIG. 4 is an on-screen transition diagram in the case where the channel most frequently viewed by the user is automatically selected in the first and second embodiments.

In FIG. 5, the storage capacity of the storage device 4 is 4
Channels, and the higher the channel in the table, the higher the priority. The number of times that data can be stored for each channel is limited and is, for example, 3 bits, that is, up to 8 times.

The storage content updating means 5 updates the content of the storage device 4 by the following algorithm. First, when the channel 600 is selected in the state 1, since the channel 600 is not in the storage device, the channel 600 is replaced with the channel 300 having the lowest priority.

Next, in the state 2, if the channel 600 is further selected twice, the number of times of the channel 600 becomes the same as that of the channel 200. Therefore, the priority of the most recently accessed channel 600 is set higher than that of the channel 200. I'll give it.

FIG. 3 is an on-screen display diagram showing a case where a list of channels frequently viewed by the user is displayed by the display / tuning control means 2 at this time.

In FIG. 3, the number of displayed channels is a certain fixed number, for example, the upper three channels are displayed.

Next, when the channel 700 is selected in the state 3, the number of times is 9 times, which exceeds the limit, and the number of times of all the channels is reduced to 1/2. At this time,
FIG. 4 is an on-screen transition diagram showing a state at the time of power-on when a channel most frequently viewed by the user is automatically selected by the channel selection control means 2.

[0028]
