Next, the EPG display color classification processing in the EPG screen construction unit 108 in FIG. 4 will be described in detail.
The color coding of the EPG display can be set to one of the color coding display by program start time and the color coding by genre by a user operation.

First, an example of a table used at the time of the color-coding process of the EPG display is shown in FIGS. 5 (a) to 5 (e).
explain. FIG. 5A shows an example of the genre-based color table 204, which is used when performing genre-based color-separated display as described later, and stores a correspondence between genre and display color.

FIG. 5B shows a color table 201 by start time.
This is a table that is used when performing color-coded display by start time, in particular, when performing a fixed-time program color setting process as described later, and stores a correspondence between a predetermined time and a display color. For example,
As shown in the drawing, 7:00 is red, 8:00 is blue, and a predetermined time is associated with a display color at one-hour intervals.

FIG. 5C shows a color table 202 for each start time.
This is a table used when performing color-coded display by start time, in particular, a remaining time color setting process as described later. In this table, the time from the start time of the time axis displayed on the EPG screen is stored in association with the display color at regular time intervals.

For example, when the program information for three hours from 7:00 is displayed on the EPG screen, it is from 7:01 to 7: 0
5 to 1 to 5 minutes, 7:06 to 7:10 to 6 to 10
The display color is associated with every minute and every five minutes. In other words, in the start time-based color table 202, display colors exist by the number obtained by dividing the time displayed on the EPG screen by the time interval. The left and right ends of the color table 202 by start time are theoretically connected as shown in FIG. 5C. However, in the memory 107, the address at each time interval is actually It is set and stored in association with the display color.

When the time scale of the EPG screen is 3 hours and the time interval is 5 minutes, the color table 202 by start time
Has (3 * 60) / 5 = 36 display colors as shown in FIG. 5 (c). Here, the time scale is EPG
This is the time width of the program information displayed on the screen, and can be set by a user operation in units of one hour, three hours, five hours, or the like.

The time interval is changed by the time scale on the EPG screen, and the time interval and the time scale are stored in association with each other in the display scale conversion table 205 as shown in FIG.

FIG. 5E shows a color table 203 for each start time.
This is a table used for color-coded display by start time, in particular, for a long-time program color setting process as described later. The start time-based color table 203 is a table for determining a color for a program whose program information is displayed over a plurality of EPG screens, such as program information relating to a long program.

As shown in FIG. 5 (e), this color table 203 is theoretically connected to the left and right ends of the table. Similarly to the color table 202 shown in FIG. This is set in return and stored in the memory 107.
In the long-time program color setting process, the display color shown at the illustrated reference position is set for each program. The flag indicating the reference position is stored in association with the data of the corresponding color in the color table 203 in the memory 107.

Further, the color tables 201 and 20 for each start time are provided.
Reference numerals 2 and 203 have different colors from each other, and prevent the same color from being set in each of a fixed time color setting process, a remaining time color setting process, and a long program color setting process described later.

FIG. 6 is a flowchart showing the operation of the system control unit 116 in the EPG display color classification processing, and details thereof will be described.

In step S601, the operation unit 114
When the G display instruction is input, the EPG data relating to the program in the designated time zone or near the current time is read from the EPG data storage unit 206 according to the set time scale (S602).

In S603, it is determined whether or not the display is set to the color-coded display by program start time. If it is determined that the display is set to the color-coded display by program start time, the process proceeds to S60.
Proceed to 4. If it is determined that the display is not a color-coded display by program start time, a genre-based color setting process is performed (S605).
In the genre-specific color setting processing, the genre of the program is determined based on the EPG data read in S602, and the display color corresponding to the genre is determined by the genre-specific color table 204 shown in FIG. Make settings.

In S604, it is determined whether or not the program broadcast time is equal to or longer than a predetermined length. If it is shorter than the predetermined length, the flow advances to S607. When it is determined that the program broadcast time is equal to or longer than the predetermined length, a long-time program color setting process is performed (S606). The predetermined length of the program broadcast time is set differently according to the time scale. In the long-time program color setting process, data of the display color indicated by the reference position flag in the start time-based color table 203 shown in FIG. After setting the color for a certain program, the storage position (address) of the reference position flag is moved so that the next display color is set as the reference position.

In S607, it is determined whether or not the program start time is a predetermined time.
Scheduled program color setting processing is performed (S609). In the scheduled program color setting processing, a display color corresponding to a predetermined time is determined by the start time color table 201 shown in FIG. For example, for a program that starts broadcasting at 7:00, the color table 20 shown in FIG.
1 sets red.

If it is determined that the program start time is not the predetermined time, the remaining time color setting processing is performed (S608). In the surplus time color setting processing, a difference between the program start time and the head time of the time axis in the EPG screen is obtained, and the display color corresponding to the obtained difference time is displayed in the start time color table shown in FIG. The determination is made in step 202, and color setting is performed.

For example, for a program whose program starts broadcasting at 7:08, the difference from the start time 7:00 on the time axis is 8 minutes, so that the program in the color table 202 shown in FIG. Set the blue color corresponding to ~ 10 minutes. FIG. 7 shows a display example of the EPG when the program start time is not the predetermined time.

Then, after performing each color setting process, S6
At 10, it is determined whether the program broadcast time has been changed. Here, change information indicating that the broadcast time of the program has been changed is added to the EPG data together with the content of the change, and the system control unit 116 determines whether there is a change according to the change information.

If it is determined that there is no change in the program broadcast time, the process proceeds to S612, and if it is determined that there is a change, the program broadcast time before the change and the program broadcast time after the change are determined based on the contents of the change. The display color between is subjected to gradation processing (S611). For example, as shown in FIG. 8, when the broadcast time of a program scheduled to end at 9:00 is extended, the gradation is displayed from 9:00 to the extended program end time.

In S612, it is determined whether or not all of the EPG data relating to the program designated by the user or in the vicinity of the current time has been read for the set time scale. If it is determined that not all have been read, the process returns to S602. , When it is determined that all the data have been read, the color coding processing of the EPG display ends.

FIG. 9 shows an example of an EPG display in the case where the color coding processing by program start time is performed as described above. The user selects and determines each program with a program selection cursor displayed on the EPG screen by operating the operation unit 114, thereby displaying a desired program.

As shown in FIG. 9, on the EPG screen, command buttons for changing the setting of the time scale, setting the color display by genre and the color display by program start time are displayed. When a command button is selected and determined by a program selection cursor by operating the operation unit 114, FIG.
A time scale setting screen as shown in FIG. 0 and a color-coded display setting screen as shown in FIG. 11 are displayed, and each setting can be changed.

Here, FIG. 10 shows a display example of the time scale setting screen. The user moves the selection cursor by operating the operation unit 114 to select and determine a desired time scale. For example, the selection cursor is moved by an up / down key on a remote controller (not shown), and the selection is determined by pressing a determination button. The system control unit 116 controls the EPG screen forming unit 108 to display the EPG screen on the time scale selected and determined.

FIG. 11 shows a display example of a color-coded display setting screen. The user moves the selection cursor to “color classification by genre” or “color classification by program start time” by operating the operation unit 114, and determines the selection. System control unit 1
The control unit 16 controls the EPG screen forming unit 108 to display the EPG screen in different colors according to the selected display setting.

Further, a time scale setting screen as shown in FIG. 10 and a color-coded display setting screen as shown in FIG. 11 can be selectively displayed from a menu screen (not shown).
Display the menu screen and each setting screen by the operation of 4,
Each setting can be changed. In this case, the menu screen
Switching display or multiplex display is performed independently of the currently displayed EPG screen.

Therefore, when changing the time scale on the time scale setting screen displayed from the menu screen, the time scale is changed without changing the display color of the program selected by the program selection cursor on the EPG screen.

First, since the color table used for the genre-based color classification processing is constant regardless of the change of the time scale, the normal color classification processing is performed as described above.

In the long-time program color setting process,
With the change of the time scale, the length of the program broadcast time for determining that the program is a long time program is changed. Therefore, even if the program selected by the program selection cursor is no longer a long-time program due to the change of the time scale, the EPG display is performed without changing the display color. For a program other than the program selected by the program selection cursor, the normal long-time program color setting processing is performed as described above.

On the other hand, since the color tables used in the remaining time color setting process and the scheduled program color setting process differ depending on the time scale, the following color table changing process is performed. FIG. 12 is a flowchart showing the processing operation.

In S1201, the program start time of the program selected by the program selection cursor is detected, and it is determined whether or not the program is started from a predetermined time (S12).
02). If it is determined that the program starts from a predetermined time, the display scale conversion table 2 shown in FIG.
In step 05, a time interval corresponding to the newly set time scale is determined, and the content of the start time-based color table 202 shown in FIG. 5C is changed based on the time interval.

If it is determined that the program is not started from a predetermined time, the difference between the program start time of the program selected by the program selection cursor and the start time on the time axis of the EPG screen is obtained. ), A display color corresponding to the difference is detected in the start time-based color table 202 (S12).
04).

In step S1205, a time interval corresponding to the newly set time scale is read from the display scale conversion table 205 shown in FIG. 5D, and the start shown in FIG. 5C is started based on the time interval. Hourly color table 202
To change. Here, it is determined where the difference obtained in S1204 belongs to the time interval according to the new time scale, and the display color corresponding to the time interval is determined to be the same as the display color detected in S1204. Display colors are assigned to other time intervals based on the time interval.

For example, when changing from the three-hour scale display to the five-hour scale display, if a program to be broadcasted from 7:08 is selected by the program selection cursor, FIG.
As shown in (c), the display color of the program is indigo in the three-hour scale display, but is orange in the five-hour scale display because the display color is set at 30-minute intervals. Therefore, the table of FIG. 5C is set so that 1 to 30 minutes are indigo, and display colors are assigned to other time intervals based on the 1 to 30 minutes.

As described above, in the present embodiment, the program information on the program whose program start time is the predetermined time is displayed in the display color corresponding to the predetermined time on the EPG screen.
The program start time of each program can be easily and clearly recognized.

In the present embodiment, the program information relating to the program whose program start time is not the predetermined time is displayed in the display color associated with each predetermined time interval on the EPG screen. The program start time can be easily and clearly recognized.

In the present embodiment, the display color of the program information relating to a program whose program broadcast time is equal to or longer than a predetermined length is different from the display color of the program information relating to other programs on the EPG screen. It is possible to easily and clearly recognize that the program broadcast time is long without switching the EPG screen.

In the present embodiment, the display of the portion where the program broadcast time is extended or changed is subjected to gradation processing on the EPG screen, so that the display of the extended or changed portion of the program broadcast time becomes clearer. The program start time of each program can be easily and clearly recognized.

In the present embodiment, the program information of each program is displayed in different colors on the EPG screen according to the genre or the program start time. However, the present invention is not limited to changing the display color. The display mode of the program information may be changed, for example, by changing the pattern in the frame to be displayed.

In the present embodiment, the changed portion of the program whose program broadcast time has been extended or changed is subjected to gradation processing on the EPG screen. However, the processing for the changed portion is not limited to this. Processing for changing the display mode may be performed.

In this embodiment, the change information relating to the extension or change of the program broadcast time is multiplexed on the EPG data.
By comparing the G data with the latest EPG data, the program broadcast time change information may be obtained.

In the present embodiment, in the extra time color setting processing, the display color is determined by the start time color table 202 according to the difference between the program start time and the start time of the time axis in the EPG screen. However, the display color may be determined according to the difference between the program start time and the predetermined time.

For example, the predetermined time is set to 7:00, 8: 0
The time is set to one hour, such as 0, 9:00, and a process of determining the display color according to the difference between the predetermined time and the program start time is performed. As shown in FIG. 13A, the start time color table 202 used in this process associates a difference of 1 to 60 minutes with a display color at predetermined time intervals. This predetermined time interval is determined from the display scale conversion table 205 as shown in FIG.

In the present embodiment, the time scale is set to 1 hour, 3 hours, 5 hours, and 8 hours, but the time scale is not limited to these times and may be any time.

In this embodiment, the vertical axis is the channel axis and the horizontal axis is the time axis on the EPG screen.
The display form of the PG screen is not limited to this.

As shown in FIG. 14, a bar indicating the current time may be displayed on the program table on the EPG screen. The bar display moves every predetermined time, for example, every minute, and indicates the current time. By this bar display, the correspondence between the current time and the program guide is clarified, and the visibility of the EPG screen can be further improved.

Although the digital TV receiver according to the present embodiment has a configuration including a display unit and a speaker, it may have a configuration in which a video signal and an audio signal are output to an external display device or a speaker.

Although the digital TV receiver according to the present embodiment does not include a recording unit that records a received signal, it may have a configuration that includes a recording unit that records a received signal.
