- the time interval between the time display 1 3 5 and the time display 1 4 2 is longer depending on the date. It has changed. This is because the genre of the broadcast program tends to be different depending on the time zone, and the difference in the display amount of the EPG information depending on the genre is taken into consideration. For example, less EPG information may be displayed for news programs and the like, but more drama and other EPG information will be displayed, such as explanations of stories and stories. In this way, the area is set in advance according to the T / JP99 / 0S340
- the necessary information can be obtained in more detail by weighting.
- the first display example EPG 3 (Fig. 16), the second display example EPG 5 (Fig. 17), and the third display example EPG 11 (Fig. 18) There are differences in the items.

- the second display example EPG 5 (Fig. 17) displays many items. Is displayed, and in the third display example EPG 11 (FIG. 18) that is reduced, the number of displayed EPG information items is the smallest. This is because the program information extraction means 15 in FIG.
- EPG 2 considers the size of the area in which the EPG information is to be displayed, the number of pixels used to display the area, and the number of characters that can be written in the area. This can be realized by determining the items to be displayed. For example, in EPG 3, all EPG information for the program displayed in the center of the screen is displayed, whereas in EPG 5, the display area per program is small, so video data and program Only titles are available. Furthermore, when the EPG becomes 11, the number of characters is limited and the program title is displayed halfway.
- the information in the program information cell 34 of FIG. 3 is prioritized in advance, and the items of the EPG information to be displayed are determined according to this priority.

Also, when expanding, it expands around the EPG information in the center of the screen. Then, the control waits for input of the remote controller (S24), and if any input is made from the remote controller, the process proceeds to the flowcharts of FIGS. However, if you have selected a future program that has not been broadcast and a past program that has already finished broadcasting, the screen of the currently selected program cannot be displayed on the entire screen. Instead, the screen displaying three channels (Fig. 16) is the most enlarged screen.
- shift up (S25) is selected in remote control input wait (S4), that is, when button 48 to the past program is pressed on the remote control, the selected area is scrolled up. That is, the selected area is moved up one step in the flowchart of FIG. 14 (S26). In this case, one step corresponds to one program information cell, and is displayed for 15 minutes going back in the past. Scroll down the EPG screen (S27).
- the user wants to display the EPG information going back in the past, he selects the shift on the selection area (S25). If the user wants to display the EPG information going back to the future, the user selects the selection area downward shift (S30). Also the tense T / JP99 / 05340
- shift down (S30) is selected in waiting for remote control input (S4), that is, if button 5 1 is pressed to the future program on the remote control, the selected area is scrolled down. That is, the selected area is moved down by one step in the flowchart of FIG. 15 (S31).
- One step in this case is one program information cell, and it will be displayed for 15 minutes going back to the future. Then, move the EPG screen upward (S32). Then, in the tense (S33), if the user wants to display the EPG information going back in the past, the shift (S25) on the selection area is selected. If you want to display EPG information going back in the future, select Shift down selection area (S30). If the tense is not changed, the process waits for remote control input (S34). If any input is made from the remote control, the process moves to the flowcharts of FIGS.
