Hereinafter, preferred embodiments of a display device, a display method, a display program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

[0013] (Functional configuration of display device 100)

First, the functional configuration of the display device 100 that is useful in the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a functional configuration of a display device 100 according to the embodiment.

In FIG. 1, a display device 100 includes a display unit 101, a storage unit 102, an acquisition unit 103, a selection unit 104, a detection unit 105, a determination unit 106, a reception unit 107, and a display control unit. 108 and a recording unit 109. The display unit 101 includes a display screen that displays content. Here, content is content that is broadcast at a predetermined time, for example, TV programs that are broadcast by TV stations and video information that is also distributed by providers. It is.

[0015] In addition, the display unit 101 may output content with only audio information. In this case, the display unit 101 includes a speaker that outputs content. Here, the content is content that is broadcast in a predetermined time zone, such as a radio program broadcast from a radio station or audio information distributed from a provider.

The storage unit 102 stores identification information and viewer information. Here, the identification information is information that can identify the viewer. Specifically, for example, information such as an ID and a password assigned to each viewer. The viewer information is information classified for each viewer identified by the identification information. Specifically, for example, it is information indicating the title or performer of the content that the viewer has viewed so far.

[0017] Further, the viewer information may be information input by an operation of the viewer. Specifically, for example, preference sports genre, music genre, current genre, preference information related to the current work contents and hobbies, and regional information such as region and country name. The storage unit 102 may be integrated with the display device 100 or may be a separate body such as an external device capable of communication.

[0018] Using the identification information and the viewer information stored in the storage unit 102, the acquiring unit 103 acquires a predetermined keyword associated with the viewer. Here, the predetermined keyword is information that can identify the content viewed by the viewer. Specifically, for example, it may be a keyword or genre included in the title or description of the content, or a person name or place name related to the content such as a performer or director. Further, the predetermined keyword may be acquired from arbitrary information input by an operation by the viewer. Specifically, for example, a sequence of characters created by the viewer may be acquired.

The selection unit 104 selects one content from the content being broadcast using the predetermined keyword acquired by the acquisition unit 103. For example, the selection unit 104 uses the EPG program guide and the predetermined keyword acquired by the acquisition unit 103 to select one content including the predetermined keyword from the programs in the EPG program guide. . Specifically, for example, a channel set by an operation by a viewer who has already been given, or content that is most frequently watched by the viewer and broadcast on the channel, You may select as one content.

[0020] The detection unit 105 detects the predetermined keyword acquired by the acquisition unit 103 described above from the one content selected by the selection unit 104. Specifically, for example, a predetermined keyword appearing in the telop or voice in the content is detected. If it is possible to receive a plurality of contents being broadcast, the detecting unit 105 may detect a predetermined keyword from each of the plurality of contents being broadcast.

Specifically, for example, if the received content is a TV program, a predetermined keyword can be detected from each of a plurality of contents corresponding to the number of TV tuners. In this case, depending on the number of TV tuners, a predetermined keyword can be detected from each of all contents being broadcast. Also, in this case, depending on the number of TV tuners, a predetermined keyword is detected from the content specified by the viewer or the content that is frequently watched by the viewer and broadcast on the channel. May be.

The determination unit 106 determines whether the selected one content (hereinafter referred to as “selected content”) and the currently displayed content (hereinafter referred to as “display content”) have the same power. For example, when the selected content and the display content are broadcast on the same channel at the same time, the determination unit 106 determines that they are the same.

[0023] Reception unit 107 receives an instruction operation to select selected content or display content. For example, when the determination unit 106 determines that the selected content is not the same as the display content, the reception unit 107 notifies the display screen that the selected content is being broadcast, and the viewer's intention. Displays the key to be displayed. In addition, a message prompting you to select a selection content or display content may be displayed on the display screen.

[0024] The display control unit 108 switches the content to be displayed on the display screen. For example, when the determination unit 106 determines that the selected content and the display content are not the same, the display control unit 108 switches the content to be displayed on the display screen. Further, when the instruction operation for selecting the selected content is received by the receiving unit 107, the display control unit 108 may switch the content to be displayed to the selected content. In addition, the display control unit 108 The content to be displayed may be switched to the selected content in accordance with the appearance frequency of the predetermined keyword for which the selected content power is also detected by the detection unit 105.

[0025] The recording unit 109 records content. The recording unit 109 records the display content when, for example, the display control unit 108 switches the content to be displayed. Further, the recording unit 109 may record the detected content when even one predetermined keyword is detected by the detection unit 105. Then, when the playback of the selected content is completed, or according to the appearance frequency of a predetermined keyword, the display content of the selected content may be switched to display of the recorded display content and played back.

[0026] It should be noted that the selection unit 104 described above may select one content from the content being broadcast according to the appearance frequency of the predetermined keyword whose content power being broadcast is also detected by the detection unit 105.

[0027] (Display processing procedure of display device 100)

Next, a display processing procedure of the display device 100 will be described. FIG. 2 is a flowchart showing a display processing procedure of the display device 100. In the flowchart of FIG. 2, it is first determined whether or not content is being displayed by the display unit 101 (step S201: No loop). When the content is being displayed (step S201: Yes), the selection unit 104 selects one content from the content being broadcast (step S202). In step S202, for example, using the identification information and the viewer information stored in the storage unit 102, a predetermined keyword classified as a viewer by the acquisition unit 103 is acquired. Using the EPG number table and a predetermined keyword, one content including a predetermined keyword is selected from the programs in the EPG program table.

[0028] Next, it is determined whether or not the selected content has the same power as the display content (step S203). If the selected content is not the same as the displayed content (step S203: No), it is determined whether or not the content to be displayed is switched to the selected content by accepting an instruction operation by the viewer (step S204). If it is determined to switch to the selected content (step S204: Yes), the content to be displayed is switched to the selected content (step S205), and the series of processing ends. On the other hand, if the selected content and the display content are the same in step S203 (step S203: Yes), or step S204 In step S204, if it is determined not to switch to the selected content (step S204: No), the series of processing ends.

[0029] As described above, according to display device 100 of the present embodiment, when the selected content is not the same as the display content, the display control unit 108 can switch the content to be displayed to the selected content.

[0030] Therefore, when the selected content and the display content are not the same, it is possible to easily display the content that meets the viewer's preference. As a result, viewers can effectively use free time when viewing content using free time.

[0031] Also, according to display device 100 of the present embodiment, when the selected content and the display content are not the same, display control unit 108 displays the content to be displayed in accordance with the instruction operation received by reception unit 107. Switch to selected content.

Accordingly, the display control unit 108 can switch the display content to the selected content when the receiving unit 107 receives an instruction operation. Thus, the viewer can select the content to be displayed according to his / her preference.

[0033] Also, according to display device 100 of the present embodiment, selection unit 104 uses EPG program guide and the predetermined keyword associated with the viewer acquired by acquisition unit 103, and is currently broadcasting. One content can be selected from the content.

[0034] Accordingly, since the content associated with the main viewer of the EPG program guide is selected, the content that meets the viewer's preference can be displayed easily and reliably. This allows viewers to effectively use free time when viewing content using free time.

In addition, according to display device 100 of the present embodiment, the content displayed by display control unit 108 is selected as the selected content according to the frequency of appearance of a predetermined keyword whose selection content power is also detected by detection unit 105. Can be switched.

[0036] Therefore, when a predetermined keyword appears more than a predetermined appearance frequency in the selected content, the content to be displayed can be switched to the selected content. This allows viewers to match their preferences in order to select the actual broadcast content content. Content can be viewed.

[0037] Also, according to display device 100 of the present embodiment, when selecting one content from the content being broadcast by selection unit 104, the contentor being broadcasted is also detected by detection unit 105. One content can be selected according to the appearance frequency of a predetermined keyword.

[0038] Therefore, the content not selected in the EPG program guide can be selected from the content being broadcast. As a result, the content of the actual broadcast content also selects the content, so that the viewer can view the content that better matches his / her preference.

[0039] Furthermore, according to display device 100 of the present embodiment, when the content displayed by display control unit 108 is switched to the selected content, the display content can be recorded by the recording medium.

[0040] Therefore, even when switching to the selected content, the display content can be recorded. Thus, even if the viewer switches to the content that suits his / her preference, he / she can watch the displayed content halfway and continue to watch the displayed content.

Example 1

[0041] Hereinafter, Example 1 of the present invention will be described. In the first embodiment, for example, an example in which the display device of the present invention is implemented by a navigation device mounted on a moving body such as a vehicle (including a four-wheeled vehicle and a two-wheeled vehicle) will be described.

[0042] (Hardware configuration of navigation device)

First, the hardware configuration of the navigation device 300 according to the first embodiment will be described. FIG. 3 is a block diagram illustrating a hardware configuration of the navigation device according to the first embodiment. In Fig. 3, the navigation device 300 includes a CPU 301, a ROM 302, a RAM 303, a magnetic disk drive 304, a magnetic disk 305, an optical disk drive 306, an optical disk 307, and an audio IZF (interface). ) 308, microphone 309, speaker 310, input device 311, video IZF312, display 313, communication I / F314, TV tuner 315, 316, GPS unit 317, and various sensors 318 Prepare and speak. Each component 301 to 318 is connected by a bus 320.

First, the CPU 301 governs overall control of the navigation device 300. ROM302 Programs such as a boot program, a communication program, and a display program are recorded. The RAM 303 is used as a work area for the CPU 301. In ROM 302 or RAM 303, for example, a memory area such as an EPG program guide that can rewrite information acquired from the external force of navigation device 300 is secured.

The magnetic disk drive 304 controls reading and writing of data from and to the magnetic disk 305 according to the control of the CPU 301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, HD (node disk) or FD (flexible disk) can be used.

In addition, the optical disk drive 306 controls reading and writing of data with respect to the optical disk 307 according to the control of the CPU 301. The optical disc 307 is a detachable recording medium from which data is read according to the control of the optical disc drive 306. The optical disk 307 can use a writable recording medium. The removable recording medium may be a power MO of the optical disk 307, a memory card, or the like.

[0046] Various control programs and various types of information are recorded on a recording medium such as the magnetic disk 305 and the optical disk 307 in a state readable by a computer. Examples of the various information include map information used for route search and route guidance. The map information recorded on the recording medium has background data representing features (features) such as buildings, rivers, and the ground surface, and road shape data representing road shapes!

[0047] Furthermore, viewing history information representing recorded content is recorded on the magnetic disk 305 and the optical disk 307. Here, the viewing history information is, for example, the title of the content that has been viewed so far, the name of the performer (performer), the name of the place related to the genre or content, and the number of times the content has been viewed within the past predetermined period. This information represents the number and the number of times recorded. Specifically, content is, for example, video content such as TV programs and DVDs that have been viewed so far, and music content such as CDs.

[0048] In addition, viewing keywords are recorded on the magnetic disk 305 and the optical disk 307! RU

Here, the viewing keyword is information that can identify the content viewed by the user. For example, viewing keywords are extracted based on the user's viewing history. Specifically, for example, the title of the content viewed in the past and the name of the performer.

[0049] Further, the viewing keyword may be, for example, preference information included in user attribute information. Specifically, it may be a favorite sports genre, music genre, current genre, or preference information such as the current job or hobby, which is input by the user via the input device 311. Further, the viewing keyword may be information on the destination point or the destination point attribute, for example. Specifically, it may be information on a place set as a destination point by the user in advance via the input device 311 or a facility obtained as a result of searching around the place set as the destination point.

[0050] The viewing keywords may be recorded for each user. In this case, for example, an ID is set for each user, and viewing keywords are recorded by classifying the set IDs. As a result, the viewing keyword can be extracted for each user by specifying the ID thereafter. In addition, the recording medium such as the magnetic disk 305 and the optical disk 307 may contain content such as video and music in advance, and the video and video are controlled according to the control of the magnetic disk drive 304 and the optical disk drive 306. A configuration may be used in which content such as music is recorded.

[0051] In the first embodiment, the force for recording the map information, the content, and the like on the recording medium such as the magnetic disk 305 and the optical disk 307 is not limited to this. The map information content may be recorded on a server outside the navigation device 300. In this case, the navigation device 300 acquires server force map information and content via the network through the communication IZF 314, for example. The acquired information is stored in RAM 303 or the like.

The audio IZF 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The sound received by the microphone 309 is AZD converted in the sound IZF308. For example, the microphones 309 may be installed near one of the vehicle's sun noisers, and the number thereof may be one or more. Note that the sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data. The speaker 310 outputs a sound obtained by DZA-converting a predetermined sound signal in the sound IZF308. [0053] Examples of the input device 311 include a remote controller having a plurality of keys for inputting characters, numerical values, and various instructions, a keyboard, and a touch panel. The input device 311 may be realized by any one form of a remote controller, a keyboard, and a touch panel, but may be realized by a plurality of forms.

In addition, the video IZF 312 is connected to the display 313. Specifically, the video I / F 312 includes, for example, a graphic controller that controls the entire display 313, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. Based on the image data output from the! /, The control IC for controlling the display 313 is used.

[0055] Further, the display 313 displays icons, cursors, menus, windows, or various data such as characters and images. On the display 313, the map data described above is drawn in two or three dimensions. The map data displayed on the display 313 can be overlaid with a mark or the like indicating the current location of the navigation device 300. The current location of the navigation device 300 is acquired by a GPS unit 317, which will be described in detail later.

[0056] As the display 313, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be used. The display 313 is installed near the dashboard of the vehicle, for example. A plurality of displays 313 may be installed on the vehicle, for example, near the dashboard of the vehicle or around the rear seat of the vehicle.

In addition, the communication IZF 314 is connected to a network via radio and functions as an interface between the navigation device 300 and the CPU 301. The communication I / F 314 is further connected to a communication network such as the Internet via radio, and functions as an interface between the communication network and the CPU 301.

[0058] Communication networks include LANs, WANs, public line networks and mobile phone networks. Specifically, communication IZF314 is composed of, for example, FM tuner, VICS (Vehicle Information and Communication System) Z beacon Resino, wireless navigation device, and other navigation devices. Get road traffic information such as traffic regulations. VICS is a registered trademark. [0059] Further, at least two TV tuners 315 and 316 are connected to the communication IZF 314. The TV tuners 315 and 316 receive radio waves (TV radio waves) including electric signals of TV programs that are modulated at a TV station and transmitted on a high-frequency carrier wave. Then, the specific frequency of the TV wave is obtained from the received radio wave. The obtained TV radio wave is decomposed again into a carrier wave and an electric signal by audio detection and video detection. Note that the transmission / reception of TV radio waves and the processing of received TV radio waves are well-known techniques, and thus description thereof is omitted. Each tuner of the TV tuners 315 and 316 can be set individually.

[0060] In addition, the GPS unit 317 uses a received wave from a GPS satellite and output values from various sensors 318 described later, the current location of the navigation device 300 (current location of the vehicle equipped with the navigation device 300). Is calculated. The information representing the current location is information that identifies one point on the map data, such as latitude'longitude and altitude. The GPS unit 317 outputs an odometer, a speed change amount, and an azimuth change amount using output values from the various sensors 318. As a result, it is possible to analyze vehicle behavior such as sudden braking, sudden braking, and dollars.

[0061] Here, a method of specifying the current location using the GPS unit 317 will be described. First, in GPS, a total of 24 GPS satellites are arranged, 4 each in 6 orbital planes around the earth. These satellites are always orbited so that the same satellites are located at the same time every day, and are always 5 from any point on the earth (but need to have a good view)! I can see the satellite.

[0062] A cesium (Cs) atomic clock (oscillator) is mounted on the GPS satellite, and the accurate time is recorded in synchronization with the time of each satellite. In addition, each satellite is equipped with two cesium oscillator power units and two rubidium (Rb) oscillators. This is because accurate time is indispensable for GPS position measurement.

[0063] GPS satellite force and others are transmitting radio waves with two frequencies of 1575.42MHz (Ll) and 1227.60MHz (L2) (hereinafter referred to as "GPS signals"). This radio wave is modulated by a random number code called pseudo random code (Pseudo Random Noise Code). When it is received by the GPS unit 317, etc., the signal content is resolved by referring to the code corresponding to the random number table. Read.

[0064] The GPS unit 317 measures the time difference between the time when the GPS satellite force GPS signal is emitted and the time when the device main body receives the GPS signal from the decoded code and the clock inside the device main body. Then, multiply the time difference by the propagation speed of the radio wave to calculate the distance from the GPS satellite to the device itself (distance = speed x time). This time is synchronized with Coordinated Universal Time (UT C).

[0065] Since accurate information on the orbit is sent from the GPS satellite, the current location of the GPS satellite can be accurately known. Therefore, if the distance of the GPS satellite force is known, the current position of the main body of the device is any point on the sphere centered on the GPS satellite and having the calculated distance as the radius. The GPS signal code string is repeatedly sent at intervals of about lms. Since the propagation speed of the GPS signal is 400, OOOkmZs, the maximum measurement distance is 400, OOO X O. 0 01 = 400km. Therefore, it is necessary to know the current location of the device in advance for accuracy of about 100 km.

[0066] As described above, when the distances from three of the GPS satellites are calculated, the current point of the apparatus body is one of two points where three spherical surfaces intersect. In addition, one of the two points is far from the point that can be predicted, so in principle one point is determined. However, in reality, the calculated candidate points for the current location (the intersection of the three faces) are not 2 points. This is mainly because the accuracy of the clock mounted on the GPS unit 317 is lower than the atomic clock mounted on the GPS satellite, and an error occurs in the calculation result.

[0067] For this reason, the GPS unit 317 receives GPS signals from a total of four GPS satellites.

This can be considered to be obtained by introducing new information (formula) with the error of the clock on the GPS unit 317 side as another unknown. In this way, by receiving GPS signals from GPS ^^^ 317 «and four GPS satellites, it is possible to obtain an almost accurate current location that converges to one point.

[0068] The various sensors 318 output information such as a vehicle speed sensor, an acceleration sensor, and an angular velocity sensor that can determine the position and behavior of the vehicle. The output values from the various sensors 318 are used for the calculation of the current location by the GPS unit 317 and the measurement of changes in speed and direction. [0069] The display unit 101, the selection unit 104, the detection unit 105, the determination unit 106, the reception unit 107, the display control unit 108, and the recording unit 109 included in the display device 100 illustrated in FIG. The CPU 301 executes a predetermined program using the programs and data recorded in the ROM 302, RAM 303, magnetic disk 305, optical disk 307, etc. in the navigation device 300 shown in FIG. 3, and controls each part in the navigation device 300 This function is realized.

That is, the navigation device 300 according to the embodiment executes the program recorded in the ROM 302 as a recording medium in the navigation device 300 to perform the functions provided in the display device 100 shown in FIG. The display processing procedure shown in 2 can be used.

[0071] (Program switching process procedure of the navigation device 300)

Next, the program switching process procedure of the navigation device 300 of the first embodiment will be described. FIG. 4 is a flowchart illustrating a program switching process procedure of the navigation device 300 according to the first embodiment. In the flowchart of FIG. 4, first, it waits until an EPG program guide is acquired (step S401: No loop). When the EPG program guide is acquired (step S401: Yes), a program list is created (step S402).

[0072] In step S402, for example, it is determined whether or not the program is included in the EPG program guide acquired in step S401, which includes the above-described viewing keyword. If the viewing keyword is in the EPG program guide, a program list is created. Specifically, it is assumed that a program list including program A is created. Also, for example, the program list is secured in a rewritable memory area of the ROM 302 or RAM 303.

[0073] Next, the process waits until the start time of No. 1A in the program list created in step S402! (Step S403: No loop). If the start time of program A is reached (step S403: Yes), it is determined whether program B (the program that is currently viewed! S404). If program B and number 1A are not the same (step S404: Yes), it is then determined whether or not to switch the broadcast channel (step S405). In step S405, for example, program information such as “19:00: 6 Channel A Amusement Park All” and a program switching message such as “Do you want to change the program?” Keys that display the intention of whether or not to switch programs such as “ha” and “, e” are displayed at a position such as the lower end of the display screen on display 313 that does not hinder program viewing. (See Figure 5). Then, by determining which key has been operated, it is determined whether or not the broadcast channel is to be switched. In this case, in operation, the user shall operate any key of “Ha! /,” Or “rv,, e”.

If the broadcast channel is switched in step S405 (step S405: Yes), recording of program B is started (step S406), and the broadcast channel is switched to program A (step S407).

[0075] Then, it waits until program A ends (step S408: No loop). When program A ends (step S408: Yes), follow-up playback of program B is started (step S40). 9) A series of processing is terminated. In step S409, program B is played back at the start of program while recording of program B started in step S406 is continued.

[0076] It should be noted that since this is a well-known technique, the description is omitted. Playing a recorded part while continuing to record a program as in step S409 is called "chase playback". In the follow-up playback, whether to end the recording of the program B is determined by, for example, an input operation by the user. Specifically, the end time of the program being recorded may be acquired from the EPG program guide, and the user may be notified and selected when the end time of the program is reached. On the other hand, if the yarn number 1A and program B are the same in step S404 (step S404: No), or if the broadcast channel is not switched in step S405 (step S405: No), the series of processing ends. To do.

[0077] In the description of Fig. 4, the force for waiting until the end time of program A in the loop of step S408: No is not limited to this. For example, if there is an input operation to switch the broadcast channel by the user while the thread 1A is displayed, priority is given to switching the broadcast channel according to the user's input operation.

[0078] Further, for example, a key for indicating whether or not to return to the program B such as "Return" and "As is" is displayed at the lower end of the display screen on the display 313 so as not to hinder the viewing of the program. The warp 1A is displayed during broadcasting at the correct position. Then, by determining which key has been operated, the follow-up playback of program B is started without waiting for the end time of program A. May be. In this case, in operation, the user shall operate either the “Return” or “As is” key. When the “as is” key is operated, the keys such as “return” and “as is” may be stopped and the program A may be waited for until the end of program A.

[0079] In the first embodiment, the warp and switching process is performed in the navigation device 300, but the present invention is not limited to this. The same program switching process may be performed on portable devices and home recording devices.

[0080] (Example of display of warp and switching information)

FIG. 5 is an explanatory diagram showing an example of a display screen for program switching information. In the display screen 500 shown in FIG. 5, the program switching information 510, the program information 520, and the power display 313 are displayed at positions that do not hinder program viewing, such as the lower end of the display screen 500. ing. The program switching information 510 includes a program switching message 511 and keys 512 and 513 for displaying a user's intention. The program information 520 includes a program start time 521, a broadcast channel 522, and a program title 523. The program switching information 510 and the program information 520 may be displayed at arbitrary positions selected by the user, such as the upper end and the left and right ends of the display screen 500, for example.

[0081] The program switching information 510 is, for example, a program switching message such as “Do you want to change the program?” And an intention display indicating whether or not the program is switching between “ha,” and “,, e”. Key. Then, it is determined whether or not to switch the program by determining which key is operated or not. In this case, in operation, the user shall operate one of the keys “Yes” or “ヽ, e”. If the Γ, E ”key is operated, stop displaying the keys such as“ Yes ”and“ No ”and broadcast the program you are watching.

[0082] Further, the program information includes, for example, information related to a program such as "19:00: 6 Channels All of amusement park". In this case, the program information displays information that is effective in operating the keys 512 and 513 that indicate the intention of the user.

As described above, according to the navigation device 300 of the first embodiment, when the selected content is not the same as the display content, the display control unit 108 selects the content to be displayed. You can switch to selected content.

Therefore, if the selected content and the display content are not the same, it is possible to easily display the content that meets the viewer's preference. As a result, viewers can effectively use free time when viewing content using free time.

[0085] Also, according to the navigation device 300 of the first embodiment, when the selected content and the display content are not the same, the display control unit 108 displays according to the instruction operation received by the reception unit 107. The content can be switched to the selected content.

Accordingly, the display control unit 108 does not switch the content to be displayed until the receiving unit 107 receives an instruction operation. Thus, the viewer can select the content to be displayed according to his / her preference.

[0087] Also, according to the navigation device 300 of the first embodiment, the selection unit 104 uses the EPG program guide and the predetermined keyword associated with the viewer acquired by the acquisition unit 103.

It is possible to select the same content as the content being broadcast.

[0088] Therefore, since the content associated with the main viewer of the EPG program guide is selected, the content that meets the viewer's preference can be displayed easily and reliably. This allows viewers to effectively use free time when viewing content using free time.

Furthermore, according to the navigation device 300 of the first embodiment, when the content to be displayed is switched to the selected content by the display control unit 108, the display content can be recorded by the recording medium.

[0090] Therefore, even when switching to the selected content, the display content can be recorded. As a result, when viewing content using idle time,

, Viewers can use their free time effectively.

Example 2

[0091] Next, Example 2 of the present invention will be described. In the second embodiment, the timing for guiding the switching to the program A being viewed is different from the timing in the navigation device 300 described in the first embodiment. In Example 2, the above-described Example 1 and The same parts are denoted by the same reference numerals, and description thereof is also omitted.

[0092] (Program switching process procedure of the navigation device 300)

FIG. 6 is a flowchart illustrating a program switching process procedure of the navigation device 300 according to the second embodiment. In the flowchart of FIG. 6, first, it waits until an EPG program guide is acquired (step S601: No loop). When the EPG program guide is acquired (step S601: Yes), a program list is created (step S602). In step S602, a program list is created in the same manner as in step S402.

Next, it waits until the start time of No. 1A in the program list created by! / In step S602 (step S603: No loop). When the start time of program A is reached (step S603: Yes), monitoring and recording of program A are started (step S604). Here, the monitor of the yarn 1A monitors, for example, whether or not a viewing keyword appears in the audio or video in the yarn 1A. Specifically, if the telop or audio in program A contains text or audio that corresponds to the viewing keyword, or if the video of program A is analyzed and the video that corresponds to the viewing keyword is found. Suppose that a viewing keyword appears. The monitor of program A monitors, for example, the frequency of viewing keywords in program A. Specifically, the number of viewing keywords that appear within a predetermined period may be monitored.

[0094] Next, after waiting for the viewing keyword to appear more than a predetermined frequency in program A (step S605: No loop), if the viewing keyword appears more than a predetermined frequency (step S605: Yes), Then, it is determined whether program B (the program that is currently being viewed) and thread # 1A are not the same (step S606). If program B and number 1A are not the same (step S606: Yes), it is then determined whether or not to switch broadcast channels (step S607). In step S607, as in step S405, it is determined whether or not to switch the broadcast channel.

[0095] When the broadcast channel is switched in step S607 (step S607: Yes), recording of program B is started (step S608), and then chase playback of program A is started (step S609). . In step S609, the program A is reproduced from the recording start time (start time) while continuing to record the program A started in step S604. On the other hand, in step S606, if program B and number 1A are the same (step S6 06: No), or if the broadcast channel is not switched (step S607: No), the series of processing ends.

[0096] After that, it waits until program A ends (step S610: No loop), and when program A ends (step S610: Yes), it stops the follow-up playback of program A and The chasing playback of B is started (step S611), and the series of processing ends. In step S611, program B is reproduced from the recording start time while continuing to record program B started in step S609.

[0097] In the description of FIG. 6, step S609 Tsukoo! /, The power of playing back the thread 1A from the recording start time is calculated for a predetermined time from the timing of recording the program B. It is also possible to play back the power at the time of going back. By doing so, the video of the scene desired by the viewer can be accurately displayed.

Further, in the description of FIG. 6, when the start time of the program A is reached in step S604, it is not limited to this. From the start time of program A, recording may be started when a viewing keyword appears for the first time, starting with the monitor.

[0099] Further, in the explanation of FIG. 6, when the start time of the program A is reached in step S603: Yes, the power to start monitoring of the yarn 1A in step S604. You can always monitor broadcast channels that are viewed frequently or broadcast channels specified by users.

[0100] In the description of FIG. 6, the force that waits until the end time of program A in the loop of step S610: No is not limited to this. Continue watching the monitor in program A started in step S604, and if the viewing keyword does not appear more than the specified frequency, stop chasing playback of program A and start chasing playback of program B May be.

[0101] As described above, according to the navigation device 300 of the second embodiment, the content to be displayed by the display control unit 108 is selected according to the appearance frequency of the predetermined keyword detected by the detection unit 105. Switch to selected content.

[0102] Therefore, the predetermined keyword does not appear more than the predetermined appearance frequency in the selected content In this case, the content to be displayed cannot be switched to the selected content. This makes it possible to reliably display content that suits the viewer's taste.

[0103] Also, according to the navigation device 300 of the second embodiment, when the selection unit 104 selects content with the same content power during broadcasting, the content power during broadcasting detected by the detection unit 105 is detected. One content can be selected according to the appearance frequency of the keyword.

[0104] Therefore, content that has not been selected in the EPG program guide can be selected as the content of the content being broadcast. This allows viewers to more reliably view content that suits their preferences.

[0105] As described above, according to the display device 100, the display method, the display program, and the recording medium of the first and second embodiments, the navigation device 300 is broadcasting using the information about the viewer. It is possible to select and output one content from among the content. As a result, the viewer can easily and reliably view content that matches his / her preference. Therefore, when viewing the content using the free time, the viewer can use the free time effectively.

[0106] The display method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
