(S 50) At this time, in a preferred embodiment of the present invention, the program as shown in Figs. It may be desirable to include a day display block that can indicate the currently selected day of the week on the guide screen. Also, as shown in FIG. 4, the day display block included in the program guide screen may display a predetermined symbol or character capable of distinguishing each day of the week, and the currently selected day located in any one of the symbol or character. It may be composed of a highlight or a cursor, or as shown in FIG. 5, a single day display unit and a single symbol or character representing the selected day of the week may be displayed on the single day display unit.

On the other hand, the system control unit 200 checks whether the mode change key signal is applied from the key input unit 100 while the program guide screen is displayed through the monitor in step S50 (S60), and the check result mode change key. If the signal is not applied, it is checked whether the scroll key signal is applied again (S70). At this time, the program guide screen displayed in step S50 is applied to the up / down / left / right scroll keys applied from the key input unit 100. The section displayed by the (↑, ↓, ←, →) signal (that is, the time zone and channel band of the program guide information displayed on the program guide screen) is changed, and in a preferred embodiment of the present invention, unless otherwise specified, It would be more desirable to initially set to the commonly used general control mode.

Therefore, if the mode change key signal is applied from the key input unit 100 as a result of the check in step S 60, the system controller 200 performs the day control mode. That is, if a mode change key signal is applied from the key input unit 100 and then the up / down (↑, ↓) or left / right (←, →) side scroll key signal is input from the key input unit 100, one scroll In response to the key signal, the program guide information corresponding to the day before or the day after the current day is read from the storage unit 400, and the read program guide information is displayed on the monitor through the same process as in step S50. Therefore, the display section of the program guide information (that is, the time zone of the program guide information) displayed on the program guide screen on a day-by-day basis is changed to a day of the week (ie, one day unit) (S 70). At this time, in the preferred embodiment of the present invention, it is preferable to change the time zone of the program guide information and to change the selected day indicated by the highlight or cursor on the day display block to the next day or the previous day by the above-described process. will be.

Further, in a preferred embodiment of the present invention, after the scroll key signal is applied, it is checked whether the next scroll key signal is applied for a predetermined time (for example, 1 to 3 seconds), and as a result, the predetermined time is preset. If the next scroll key signal is not applied during the operation, the display section may be changed according to the day of the week control mode, so that an effect such as jumping to a program guide screen corresponding to one or more days of the week may be obtained.

And, in the preferred embodiment of the present invention, each day of the week has a direction according to the day of the week in the order of Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, Monday, and the day before the current day of the week day control mode is performed If selected, it would be more desirable to display a program guide screen corresponding to the selected day of the week following the current day.

In addition, when the program guide screen is scrolled by day of the week, the displayed time zone of the program guide screen corresponding to the scrolled day is the same time zone as the currently displayed program guide screen, and the time zone of the program guide screen corresponding to the scrolled day of the week. Among the time zones of the frontmost time zone and the time zone of the program guide screen corresponding to the scrolled day, the preset time zone is set to any one of the exact center time zones, whereby the effect according to the present invention can be further enhanced.

In addition, if the program guide information corresponding to the day of the week selected by the day mode is not stored in the storage unit 400, it may be more effective to display a message that there is no program guide information.

On the other hand, if the mode change key signal is not applied as a result of the check in step S60, the system controller 200 checks again whether the scroll key signal is applied from the key input unit 100 (S80), and as a result, the key When the scroll key signal is applied from the input unit 1000, the system control unit 200 controls a time zone or channel corresponding to the scroll key applied from the key input unit 100 among the program guide information previously stored in the storage unit 400 by the general control mode. Representative program guide information is read out, and the read program guide information is displayed on the monitor through the same process as step S 50. At this time, a single scroll key signal is applied to an internal memory (not shown) of the system controller 200. The time zone or channel band that moves in correspondence with each other is in a predetermined interval (for example, in units of 1 hour in response to the left and right key signals, in units of 10 channels in response to the up and down key signals) Groups will be set up.

As a result, the display section of the program guide screen displayed on the monitor (not shown) by the above-described process, that is, the time zone or channel band of the program guide screen is scrolled by a predetermined interval corresponding to one scroll key signal. (S 90)
