2 is a flowchart illustrating a method of operating a digital broadcast reception device according to an embodiment of the present invention, and FIG. 3 is a view for explaining a method of operating a digital broadcast reception device according to an embodiment of the present invention. 4A and 4B are views for explaining receiving user information according to an embodiment of the present invention, and FIGS. 5A to 7C show user information and / or additional information according to an embodiment of the present invention. It is a figure for demonstrating what to do.

2 and 3, the digital broadcast reception apparatus 100 may perform step S100 of storing at least one of user information and additional information in the memory 70.

The user information may include first user information and second user information, the first user information may be text information, and the second user information is a time for outputting the first user information through the display. It may be visual information about. For example, the first user information may include memo information, schedule information, and the like. When the first user information is memo information, the second user information may be automatically set to "at next power-on", or may be arbitrarily set by the user. When the first user information is schedule information, the second user information may be arbitrarily set by a user.

A method of setting the second user information will be described below with a simple example. Suppose XX month YY is your father's birthday. The user may set the first user information as "father born". In this case, the second user information may be input as the month XX month YY. In this case, the second user information "Father's birth" may be displayed on XX month YY. Alternatively, the user may set the second user information as "one day before" and "one week before" on XX month YY. In this case, the first user information may be displayed at a time corresponding to the second user information set by the user, rather than being displayed on the XX month YY day.

The first and second user information may be input through the user input interface unit 50. Input of schedule information as the user information will be described with reference to FIGS. 4A and 4B. The digital broadcast reception device 100 provides a date selection window CW through which the user can select a date corresponding to a schedule (September 11) through the display 30, as shown in FIG. 4A. can do. Subsequently, the user may input "Father's birth" as the first user information in the user information input window UW. In addition, the user may set the schedule information to be displayed one day before the corresponding date (September 11). That is, the user may set the second user information as "one day before September 11". The method for inputting the user information described with reference to FIGS. 4A and 4B is one embodiment, and the user information may be input in various ways other than the above-described method.

The additional information may be information received through the network connection unit 20c. For example, the additional information may include information about "weather", "stock", "news", and the like received through a network such as the Internet. The additional information may include various other information in addition to the above-described information. The received additional information may be stored in the memory 70. The additional information may be received through the network connection unit 20c during a waiting time when a user is not watching a broadcast through the digital broadcast receiving apparatus 100. In this way, the additional information may be always updated and stored in the memory 70. In this case, as mentioned above, the power supply unit 90 may supply standby power to components such as the network connection unit 20c and the memory 70.

The digital broadcast reception apparatus 100 may receive information of particular interest from the user among the various types of additional information. The digital broadcast reception device 100 may display only the selected additional information on the display 30, as will be described later.

 The storing of the user information / additional information (S100) is performed at least before the first time point T1 to perform the “power-on by applying power to the display (S110)” described later. For example, the user information may be input, set, and stored by the user before the first time point T1, and the additional information may be received from the network connection unit 20c before the first time point, and may be stored in the memory. 70 may be stored.

The digital broadcast reception apparatus 100 receives power input from a user, and then applies power to the display 30 and other components for displaying an image on the display 30. The step S110 may be performed. For example, when a user inputs a "power-on" command by pressing a power switch of a remote controller or the like, a user performs a series of procedures for receiving a broadcast signal and the like and displaying it on the display 30.

In this case, a predetermined reset operation is performed on the display 30 in order to receive a broadcast signal normally and display a broadcast image based on the broadcast signal. In general, the reset operation takes several seconds of waiting time. Hereinafter, the waiting time for the reset operation will be referred to as "boot waiting time". Therefore, even after the user issues a "power-on" command through the remote control or the like, normal viewing of the broadcast is possible only after the boot waiting time has elapsed. For example, referring to FIG. 3, a few seconds between a first time point T1 where a user requests "power-on" and a second time point T2 at which a broadcast image is normally displayed through the display 30. It takes a boot waiting time of, and no special information is provided to the user through the display 30 during the boot waiting time. If there is such a boot waiting time, there is a loss time, the user can feel uncomfortable. Therefore, there is a need to prevent the user from feeling this inconvenience.

According to the operating method of the digital broadcast reception device according to the present invention, the digital broadcast reception device 100 is a step of authenticating a user before or after the "power-on" request step (S110) or at substantially the same time. S120 may be performed. This will be described later in detail.

The digital broadcast reception device 100 may perform a step of reading at least one of the user information and the additional information from the memory 70 (S130). While reading the user information / additional information, the digital broadcast reception device 100 also reads information on the type of additional information selected by the user among the second user information and / or the additional information. .

The digital broadcast reception device 100 may perform a step S140 of determining whether to display the user information / additional information based on the read information. For example, when the set second user information corresponds to the current time by comparing the time information indicated by the second user information with the current time, the digital broadcasting reception apparatus 100 may determine the second user information. It may be determined that the first user information stored corresponding to the display should be displayed. Meanwhile, while performing the step of determining whether the display is performed (S140), the digital broadcast reception apparatus 100 may also determine the type of additional information selected by the user among various additional information.

The digital broadcast reception apparatus 100 may perform the step of displaying at least one or more of the read user information and the additional information through the display 30 (S150).

The step of displaying the user information / additional information (S150) may be performed according to the determination result of the step of determining whether the display (S140). For example, when the time information indicated by the second user information does not correspond to the current time, the digital broadcast reception device 100 may not display the user information on the display 30. Meanwhile, when the additional information to be displayed is selected by the user and the additional information to be displayed is selected, the digital broadcasting reception apparatus 100 may display the additional information on the display 30.

Reading the user information / additional information (S130) and displaying the user information / additional information (S140) may be performed within the boot waiting time. For example, referring to FIG. 3, the user information / additional information may be displayed on the display 30 from the third time point T3 within the boot waiting time. In order for the broadcast image to be displayed on the display 30, a broadcast signal must be decoded and displayed after receiving the broadcast signal through the signal receiver 10, and thus a booting waiting time occurs, but the user information and the additional information Since it is stored in the memory 70 in advance, it takes a much shorter time than the boot waiting time to display it on the display 30. Therefore, the user information and / or the additional information may be displayed in the boot waiting time. It becomes possible. 5A, 6A and 7A show the user information and / or the additional information displayed on the display 30 at the boot latency. 5A, 6A, and 7A, a state in which at least one of user information and additional information is displayed on the display 30, which is input and set as described above in the message notification window MW before the broadcast screen is displayed, is shown. have. The form, type and location of the message notification window MW may vary depending on the type of the user information and / or additional information. The message notification window MW may be provided in various forms in addition to those shown in the drawing.

Furthermore, in general, since a broadcast signal is mixed with a video signal and an audio signal and then transmitted, the digital broadcast reception apparatus 100 should go through the step of separating the broadcast signal into a video signal and an audio signal after receiving the broadcast signal. . However, since the user information and / or the additional information may include only a video signal, the user information and / or the additional information do not need to be separated, such as a broadcast signal, so that the user information and / or the additional information may be displayed on the display 30 more quickly. Even when the user information and / or the additional information have both video information and audio information, the video information and audio information can be stored in the memory in a state where the video information and audio information are separated. Faster output through the display 30 and the speaker 40 can be achieved.

The digital broadcast reception device 100 may perform a step of displaying a broadcast image corresponding to a broadcast signal received through the signal receiver 10 on the display 30 after the boot waiting time has elapsed (S160). have. Referring to FIG. 3, the broadcast image may be displayed on the display 30 from the second time point. In this case, the user information and / or the additional information may be displayed overlapping with the broadcast video. 5B, 6B and 7B show that the user information and / or the additional information are superimposed together. 5B, 6B, and 7B, a broadcast screen BP is displayed on the display 30, and the message notification window MW overlaps with the broadcast screen BP.

Subsequently, the digital broadcast reception device 100 may prevent the user information and / or the additional information from being displayed any longer after a predetermined time elapses from the second time point. For example, as shown in FIGS. 5C, 6C and 7C, the message notification window MW may disappear from the display 30, and various animation effects may be added while the message notification window MW disappears. have.

Thus, according to the present invention, useful information can be provided to the user in the boot waiting time from the request for "power-on" until the broadcast image is actually displayed through the display 30.

5A to 7C illustrate the case in which the user information and the additional information are displayed as text, the user information and the additional information may be displayed in an image other than text or in a form in which text and images are combined. Can be. In this case, the image may reflect the attribute of the user information or the additional information. The images may be received from the outside, or may be pre-stored in the memory 70.

(30) can be displayed. The images IM1, IM2, IM3, IM4, IM5, and IM6 may reflect attributes of the weather information. For example, the images IM1, IM2, IM3, IM4, IM5, and IM6 may be images that allow the user to easily associate the weather information.

Although not shown in the drawing, when the user information is schedule information corresponding to a birthday, the display 30 displays an image such as a birthday cake together with displaying the first user information previously input by a user as text. Can be marked on. Alternatively, when the user information is schedule information corresponding to a hospital reservation, the first user information previously input by the user may be displayed in text and an image of the hospital may be displayed on the display 30. .

In addition, when the user information and the additional information are displayed as an image, or when the image and text are combined, the displayed image may reflect the time when the user information or the additional information is displayed. have. For example, the image may vary for each time zone. In the following, an example will be described.

However, each of the images shown in FIGS. 9A to 9C may have different brightness, saturation, color, etc. so that the user may easily associate whether the current time zone is 'am', 'pm' or 'evening'. I can make it. For example, the image IM9 illustrated in FIG. 9C relates to a cloud when there is not much sunlight when it is dark, and may easily associate with the current time zone.

In addition, depending on the time zone, other text (e.g., "Good Morning", "Good afternoon", "Good evening", etc. together with the text and / or image corresponding to the user information or the additional information) TX1, TX2, and TX3) can be displayed together, and furthermore, by receiving information on the current temperature, the current temperature (TM1, TM2, TM3) can also be displayed together.

On the other hand, if the user information or the additional information has not been input and set by the user, or if the additional information has not been received, the current time (CL1, CL2, CL3) and / or the present time at the boot waiting time. An image IM10, IM11, IM12 reflecting time can also be displayed on the display 30. 10A to 10C show the present times CL1, CL2 and CL3 and / or the images IM10, IM11 and IM12 reflecting the present times. For example, as shown in FIG. 10C, by displaying an image IM12 in which the full moon floats in the night sky on the display 30, the user may not display the current time together at the time of the evening. It allows you to guess.

Alternatively, in the above case, instead of displaying the present time and the image reflecting the present time, any image IM13, IM14, IM15 or any text stored in the memory 70 may be displayed on the display 30. ) Can be displayed. 11A-11C illustrate displaying an image on the display 30 at the boot latency.
