Description

  The present invention relates to a technique for displaying a broadcast program guide.

  With the spread of terrestrial digital broadcasts, it is expected that terrestrial digital broadcast receivers such as televisions and radios will be installed in moving bodies such as vehicles.

  By the way, unlike a television / radio receiver installed in a home, a receiver mounted on a moving body is completely turned off when the vehicle engine is stopped. When the system is started and the system is started, first, a boot program is executed, and it takes a time of several tens of seconds to several minutes until a broadcast is displayed on the display device of the receiving device.

  In general, an opening screen displaying a trademark of a manufacturer or a product is displayed until the start of the system is completed.

  Incidentally, in a car navigation apparatus, there is Patent Document 1 (Japanese Patent Laid-Open No. 2001-165676) as a technique for reducing the user's feeling of waiting when a waiting time for the user occurs.

  In this Patent Document 1, data of information to be displayed on a display device during a waiting time for the user (news and event information obtained by date, quiz, fortune-telling, psychological test and data communication) is stored in an external memory. The user can select the type of display information in advance on the setting screen. When the device starts up, each program module of the control device is launched, and the application reads the datebook data according to the date information received from the GPS data analysis module from the external memory and displays the datebook using the display module Display on the device screen. Thereafter, current location information detected by GPS data analysis is received, map data around the current location is read from the map data input device, and a map around the current location and the current location are displayed on the screen of the display device.

However, in the above technique, date information cannot be acquired unless the GPS data analysis module is activated. Usually, the analysis time of the GPS data requires a longer time than the boot time of the car navigation device, which is not realistic.
JP 2001-165676 A

  Such an opening screen display at the time of booting of the receiving apparatus is not useful information for the user, and is a technique that is difficult to solve even by Patent Document 1 and does not allow the user to spend wasted time at startup. Realization was craving.

  The present invention has been made in view of the above points, and by proposing a mechanism capable of displaying digital broadcast program information when the receiving apparatus is booted, particularly for a user who is on a moving body. It is an object of the present invention to provide a technique that can eliminate discomfort such as boredom until the start-up of the receiving device.

  As a result, it is possible to grasp the outline of the program by allowing the user to browse the program information without boring the user when the system is activated, and to output the program content from the display device immediately after the system is activated, thereby recognizing the user's willingness to view the program content. You can make it.

  In addition to the above, genre discrimination means for discriminating the video / audio type of the received program content is provided, and means for detecting the viewing frequency for each genre of the program content obtained by the genre discrimination means is further provided, The access means may transmit the program information of the genre having the high viewing frequency ranking detected above to the display control means (claim 2).

  As a result, a genre that is of interest to the user is selected, and the program information is displayed as a recommended program.

In addition, it is good also as a structure provided with the designation | designated means to designate this genre from the outside.
In addition, program information display changing means may be provided which changes predetermined program information in the program information stored in the storage means into a display state in which other program information can be identified.

  In this way, by performing highlighting display, it is possible to provide program information that matches the user's preference.

  Further, the predetermined program information in a display state that can be distinguished from the other program information may be designated from the outside (Claim 5).

  The program corresponding to the program information displayed in the identifiable display state after the activation control unit detects the completion of the activation of the system and stops reading the program information from the memory access unit. The content may be output to the display device (claim 6).

  When the user specifies the program information displayed before the system startup is completed by pressing a predetermined area (icon, etc.) on the display panel, the pressed position is held by a display microcomputer, etc. The date / time information is calculated from the position information, and when the program content corresponding to the program information is being broadcast, the program content is output to the display device as it is. Thereby, program information and program content viewing can be seamlessly realized.

  Further, it may further comprise selection means for selecting the displayed program information and setting means for setting the selected program information as viewing or recording reservation.

  Further, it may further comprise program information reception control means for receiving program information only when predetermined reception conditions are satisfied (claim 8).

  As described above, the program information may be received only when the reception level is good or higher than the predetermined value.

  In addition, the reception condition may be set by external designation (claim 9). Specifically, the reception timing, for example, the interval time (such as every few minutes), the reception level, etc. may be set by the user himself.

  Further, the program information of the genre with the highest viewing frequency order detected above may be displayed on the display control means in a state where it can be distinguished from other program information.

  Here, the display state that can be distinguished from other program information may be, for example, highlighting only predetermined program information (coloring the background, surrounding it with a thick frame, and changing the font color).

  In addition, after the activation control unit detects completion of activation of the system, transmission of the program information to the display control unit may be continued by an input instruction from the outside. This is in consideration of convenience when the user wants to continue watching the program information.

  Further, it may be possible to set in advance whether or not to continue transmission of the program information to the display control means after the activation control means detects completion of the system activation.

  ADVANTAGE OF THE INVENTION According to this invention, the mechanism which can display the program information of a digital broadcast at the time of the system boot of a receiver can be implement | achieved. Can be eliminated.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a system configuration of the present embodiment.
The receiving apparatus 1 includes an RF-Base BAND processing unit 2, an OFDM demodulation processing unit 3, a TS DEMUX processing unit 4, a video decoder 5, an audio decoder 6, a display controller (GDC) 7 (display control means), a display A device (Display) 8, a D / A converter 9, and a speaker 10 are included. Although not shown, the display device (Display) 8 includes input means such as a touch panel so that the central processing unit (CPU) 13 can recognize the push position on the display.

These are connected to an information processing system centered on a central processing unit (CPU) 13 through a bus. In addition to the central processing unit (CPU) 13, the information processing system includes a memory (RAM) 11, a memory (ROM) 12, a clock means (RTC: Real Time Clock) 14, a large-scale storage device (HDD) 15, and the like. Has been. Although not shown, the memory (RAM) 11 includes a memory controller 17 (memory access means) and a mirror register 18. The clock means (RTC) 14 is always operated by the built-in battery even when the system is off. The mirror register 18 is a register that holds the contents of the clock means (RTC), and minute, hour, day of the week, and day are held in real time (real time). The memory controller 17 is a controller that accesses the memory independently of the central processing unit (CPU) 13, and is activated and stopped by interrupt control from the central processing unit (CPU) 13.

The receiving apparatus according to the present embodiment is a receiving apparatus for terrestrial digital broadcasting, and an orthogonal frequency division multiplexing (OFD) is performed by an OFDM demodulation processing unit 3 via an RF-Base BAND processing unit 2 as a tuner.
M: Orthogonal Frequency Division Multiplexing) is subjected to AD conversion, OFDM demodulation, and error correction. Then, the video signal and the audio signal are separated by the TS DEMUX processing unit 4 and input to the video decoder 5 and the audio decoder 6, respectively.

  The video signal decoded by the video decoder is controlled by a display controller (GDC) 7 as display control means and output to a display device (Display) 8.

  On the other hand, the audio signal decoded by the audio decoder 6 is analog-converted by the D / A converter 9 and then output from the speaker 10.

FIG. 2 is a block diagram showing a hardware configuration for reading program information. Here, the program information (EPG) is extracted from the received signal by the OFDM demodulation processing unit 3 or the TS DEMUX processing unit 4. This program information is composed of text information and is periodically stored in the memory 11 under the control of a central processing unit (CPU) 13.

  Next, when the power supply of the receiving apparatus 1 is changed from the off state to the on state, the central processing unit (CPU) 13 reads the boot program from the memory (ROM) 12 and starts the system start-up process. At the same time, the memory controller 17 is activated. The memory controller 17 acquires clock information from the mirror register 18 and reads program information corresponding to the clock information from the memory 11. Specifically, in the figure, at 23: 00 (Wednesday) at 19:00, program information of the date and time is read from 0x1300.

  Here, the program information read from the memory 11 by the memory controller 17 is output and displayed from the display controller (GDC) 7 to the display device (Display) 8 via the bus.

Next, when the activation of the system is completed, an interrupt signal (ADD) is input to the memory controller 17 from the central processing unit (CPU) 13 (activation control means). As a result, the memory controller 17 interrupts access to the memory 11. As a result, the display of the program information on the display device (Display) 8 is interrupted, and the display is switched to a display screen for car navigation or the like by normal control of the central processing unit (CPU) 13.

  FIG. 3 shows an address map of the memory 11 showing another specific example. As shown in the figure, the memory 11 has a recommended program information registration area (0x0800-) in addition to the normal program information registration address (0x1300-).

Digital terrestrial reception data (TS: Transport Stream) includes video / audio type identification data (PSI: Program Specific Information / SI: Service Information), and the genre of program content is extracted from these data. can do. The central processing unit (CPU) 13 extracts the genre information of the content from the TS DEMUX processing unit 4 when the program content is received (at the time of viewing), and constructs a database in the memory 11. In this database, the ranking of viewing frequency is set for each genre (for example, drama, sports, news, etc.). While the system is in operation, the central processing unit (CPU) 13 sorts the received program information by genre by the processing of the central processing unit (CPU) 13, and when the power-off signal is input, the central processing unit (CPU) 13 , Moving the recommended program information in the genre (here, the drama program information if the first viewing genre is drama from the database) to the “recommended program information” area of the memory 11, Thereafter, the system is turned off.

FIG. 5 shows the processing procedure of such a central processing unit (CPU) 13. That is, the central processing unit (CPU) 13 determines whether or not it is a preset acquisition time (S01). When the acquisition time is reached, the central processing unit (CPU) 13 starts acquiring program information (S02).

  Next, a genre is extracted from the acquired program information, and program information (date, start / end time, program name, channel) for each genre is stored in the memory 11 (S03).

When the central processing unit (CPU) 13 detects that the system is turned off (S04), the recommended program information in the genre (here, the first in the viewing genre from the database is drama). In some cases, the drama program information) is moved to the “recommended program information” area of the memory 11, and then the system is turned off (S05).

  Next, when the power supply of the receiving device 1 is changed from the off state to the on state, the central processing unit (CPU) 13 reads the boot program from the memory (ROM) 12 and starts the system start-up process. At the same time, the memory controller 17 is activated. The memory controller 17 first accesses the storage address (0x0800) of recommended program information. As a result, recommended program information (here, drama program information) is read from the memory 11 and output / displayed from the display controller (GDC) 7 to the display device (Display) 8 via the bus (see FIG. 4). ).

Next, when the activation of the system is completed, a different address signal (ADD) is input to the memory controller 17 from the central processing unit (CPU) 13 (activation control means). As a result, the memory controller 17 interrupts access to different memory areas of the memory 11. As a result, the display of the program information on the display device (Display) 8 is interrupted, and the display is switched to a display screen for car navigation or the like by normal control of the central processing unit (CPU) 13.

  FIG. 6 shows a genre designation screen of the display device (Display) 8. The display device (Display) 8 is provided with a touch panel and functions as designation means for designating the genre from the outside.

  That is, the central processing unit (CPU) 13 displays the screen shown in FIG. When the user designates a genre (for example, drama) in this state, the program information of the designated genre from the database in the memory 11 is moved to the recommended program information area shown in FIG. This movement of the program information may be executed, for example, when the central processing unit (CPU) 13 detects that the system is turned off.

  Next, when the power supply of the receiving device 1 is changed from the off state to the on state, the central processing unit (CPU) 13 reads the boot program from the memory (ROM) 12 and starts the system start-up process. At the same time, the memory controller 17 is activated. The memory controller 17 first accesses the storage address (0x0800) of recommended program information. Thereby, the program information (here, drama program information) of the genre designated by the user is read from the memory 11 and output and displayed from the display controller (GDC) 7 to the display device (Display) 8 via the bus. (See FIG. 4).

Next, when the activation of the system is completed, a different address signal (ADD) is input to the memory controller 17 from the central processing unit (CPU) 13 (activation control means). As a result, the memory controller 17 interrupts access to different memory areas of the memory 11. As a result, the display of the program information on the display device (Display) 8 is interrupted, and the display is switched to a display screen for car navigation or the like by normal control of the central processing unit (CPU) 13.

  FIG. 7 shows a part of the hardware configuration for obtaining information such as audience rating information from the outside.

  In the figure, a central processing unit (CPU) 13 acquires audience rating ranking data (daily, weekly, genre, etc.) obtained from an external center and stores it in the memory 11 via the DCM 19 and the DCM interface 20.

  Then, the central processing unit (CPU) 13 weights the program information periodically stored in the memory 11 based on the audience rating data stored in the memory 11 during the system operation, and displays the highlight flag Is added. FIG. 9 is an address map of the memory 11, and more specifically, an emphasis flag is added to program information at the top of the audience rating data obtained above, in this case, program information of 0x1400. With this highlight flag, the program information can be displayed in a display state that can be distinguished from other program information.

Specifically, an HTML or XML tag can be used for this highlight flag.
FIG. 8 shows the processing procedure of such a central processing unit (CPU) 13.
That is, the central processing unit (CPU) 13 determines whether or not it is a preset acquisition time (S20). When the acquisition time is reached, the central processing unit (CPU) 13 starts acquiring program information (S21).

  Next, the acquired program information is compared with program information having a higher audience rating obtained in advance. If the program information has a higher audience rating, a highlight flag is added to the program information and registered in the memory 11 (S22).

  When the central processing unit (CPU) 13 detects that the system is turned off, the recommended program information in the genre (here, the program information in which the highlight flag at the top of the audience rating is added). Is moved to the “recommended program information” area of the memory 11, and then the system is turned off (S05).

  Next, when the power supply of the receiving device 1 is changed from the off state to the on state, the central processing unit (CPU) 13 reads the boot program from the memory (ROM) 12 and starts the system start-up process. At the same time, the memory controller 17 is activated. The memory controller 17 first accesses the storage address of recommended program information. As a result, recommended program information (in this case, drama program information) is read from the memory 11 and output / displayed from the display controller (GDC) 7 to the display device (Display) 8 via the bus.

  At this time, since the highlight flag is set for the program information, for example, the program information is displayed on the display device 8 in a state where the background is colored, surrounded by a thick frame, or the font color is changed.

  It should be noted that the program information highlighting may be performed on a program for which a user has designated a genre in advance. FIG. 10 shows the display screen of the display device 8 where the user designates the genre to be highlighted and the state of the database. In this way, for example, if the user designates the genre of “drama” in advance as the genre, the program information of the drama with the highest audience rating can be highlighted.

FIG. 11 and FIG. 12 are flowcharts showing processing when the user selects program information displayed on the display device 8. FIG. 13 shows the internal configuration of the central processing unit (CPU) 13, particularly the configuration used in this embodiment. That is, the core unit 13b is a part that realizes the function of the central processing unit (CPU) 13 described above. In this embodiment, in addition to the core unit 13b, the display microcomputer interface 13a, the reception system control unit 13c, It has a recorder control unit 13d. The display microcomputer interface 13a is connected to the display microcomputer 21 via a bus.

  In this configuration, first, the screen display shown in FIG. 4 is continued until the central processing unit (CPU) 13 detects the completion of system startup.

  Here, when the user designates the program information displayed on the display device 8 with the touch panel function, the display microcomputer 21 provided in the display device 8 displays the coordinate value of the display position pressed by the user in the memory area. Hold (S41).

  Next, when the central processing unit (CPU) 13 detects the completion of the system startup (S40) and the display microcomputer 21 is notified via the bus, the display microcomputer 21 displays the display pressed by the user in step S41. Are sent to the central processing unit (CPU) 13 (S42). Then, the display microcomputer clears the coordinate value of the display position held in the memory area (S43).

  On the other hand, when the central processing unit (CPU) 13 recognizes that the activation of the system has been completed (S30), it acquires the coordinate value of the display pressed by the user from the display microcomputer 21 (S31). Then, the program information displayed there is detected from the coordinate value, and the program distribution time of the program information is detected (S32).

  Next, the central processing unit (CPU) 13 determines whether or not it corresponds to the program distribution time at that time (currently broadcasting) (S33).

Here, if it corresponds to the program distribution time (currently being broadcast), the channel is read from the program information corresponding to the coordinate value, and the channel is set in the reception system control unit 13c (S34). Based on this, the reception system control unit 13c instructs the RF-Base BAND processing unit 2 to receive the broadcast of the channel.

  In step S33, if the program distribution time is not met (not the broadcast time), the channel is set as a reception channel for the reception system control unit 13c, and further to the recording system control unit 13d. The program distribution time is instructed and a recording reservation is set.

  In this way, even when the user designates program information displayed on the display device 8 at the time of booting, the designated information can be taken over after booting (after completion of startup) to receive or record the designated broadcast. It becomes.

  FIG. 14 and FIG. 15 are a system configuration and a flow diagram for embodying program information reception control means for performing reception of program information only under predetermined reception conditions.

  In FIG. 14, the output of the OFDM demodulation processing unit 3 is detected by the reception level A / D converter 22 to detect the level of the reception signal, and the detection result is notified to the central processing unit (CPU) 13. The reception level A / D converter 22 may be integrated with the OFDM demodulation processing unit 3. Other configurations are the same as those described with reference to FIG.

When the central processing unit (CPU) 13 detects the reception level detected by the reception level A / D converter 22 from the RF-Base BAND processing unit 2 through the OFDM demodulation processing unit 3, the reception level is set in the memory 11. The reference level value (set value) is compared (S50). If this is equal to or higher than the reference level value (set value), the received program information is stored in the memory 11 (S51).

  The reference level value (set value) may be set in advance in the memory 11 by an external user input instruction, or may be read from the memory (ROM) 12 as an initial value.

  Specifically, the embodiment shown in the figure is effective in a case where the radio wave reception state is bad while the vehicle is moving and the received program information data is lost.

  FIG. 16 is a processing flow of the central processing unit (CPU) 13 for setting program information receiving conditions by external designation. FIG. 17 is an explanatory diagram for explaining the setting of the interval time at that time.

  The central processing unit (CPU) 13 refers to the condition setting area of the memory 11 to determine whether or not it is a storage / information acquisition time (interval time) set in advance by the user (S60). If it is the information acquisition time (interval time), the received program information is stored in the memory 11 (S61).

  The interval time can be set in hours and minutes via the interface screen of the display device 8 as shown in FIG. For example, when “2 hours” is set, the central processing unit (CPU) 13 performs processing for acquiring program information and storing it in the memory 11 according to the flow shown in FIG. Regarding the condition setting, the reception level can be set in addition to the interval time, and a slider is displayed on the display device 8 so that the marker on the touch panel can be set to be movable with a user's finger or the like or an arrow button. Good. The interval time and the reception level set in this way are stored in a reception condition setting area (not shown) of the memory 11.

  FIG. 18 shows memory access means, that is, the memory controller 17 transmits program information of a genre having a high viewing frequency ranking to the display controller (GDC) 7 (the display control means) in a display state distinguishable from other program information. It explains the concept of.

  That is, the recommended program is read from the memory 11 as shown in FIG. 4 and output / displayed from the display controller (GDC) 7 to the display device (Display) 8 via the bus. When a large screen area can be secured, program information may be displayed as a program guide with time arranged in the vertical direction and channels arranged in the horizontal direction as shown in the right diagram of FIG. At that time, as described with reference to FIG. 3, only program information having a high viewing frequency ranking, that is, recommended program information may be highlighted. Here, with respect to highlighting, a highlighting flag as described in FIG. 9 may be set. The central processing unit (CPU) 13 may switch between the screen display displayed in the left diagram of FIG. 18 and the tabular screen display displayed in the right diagram depending on the state of the moving body (vehicle). For example, when the engine is started by the engine key and the system is in the boot state (starting state), when the vehicle is stopped, the screen shown in the right figure of FIG. It is also possible to control to display a screen as shown in the left figure when the vehicle starts.

  FIG. 19 shows a processing flow in which display of the program information is continued by an input instruction from the outside even after the central processing unit (CPU) 13 as the activation control means detects completion of activation of the system. is there.

  In this example, first, the screen display (display of program information) as described in FIG. 4 is continued until the central processing unit (CPU) 13 detects the completion of the activation of the system.

  When the central processing unit (CPU) 13 detects that the system has been activated (S70), it determines whether or not to continue displaying the program information (S71). At this time, an interface screen as shown in the right diagram of FIG. 19 is displayed on the display device 8, and whether or not to continue the program information can be selected by a user input.

  Here, when continuation of display (here, “Yes” region) is instructed, the program information shown in FIG. 4 or FIG. 19 is continuously displayed as it is.

  On the other hand, when non-continuation of display (here, “No” area) is designated, the central processing unit (CPU) 13 obtains from the display screen (system information stored in the memory 11) when the power is turned off the last time. Or display the original car navigation screen on the display device 8 (S72).

  FIG. 20 shows a processing flow and its setting screen when the user initial setting is whether or not to continuously display the program information even after the system startup is completed.

  First, the central processing unit (CPU) 13 displays the interface screen shown in the right figure of the figure on the display device 8 as an initial setting, and asks the user whether or not to continue displaying the program display screen even after the system startup is completed. Let it be set. The setting information at this time is recorded in the user initial setting information recording area of the memory 11.

  In this example, first, the screen display (display of program information) as described in FIG. 4 is continued until the central processing unit (CPU) 13 detects the completion of the activation of the system.

  When the central processing unit (CPU) 13 detects that the system has been started (S80), the central processing unit (CPU) 13 accesses the user initial setting information recording area of the memory 11 to display the program. It is determined whether continuous display of the screen is set. Here, when the continuous display is set, the program information shown in FIG. 4 or FIG. 19 is continuously displayed as it is.

  On the other hand, when non-continuation of display is set, the central processing unit (CPU) 13 displays a display screen (obtained from system information stored in the memory 11) at the previous power-off or an original car navigation screen. Is displayed on the display device 8 (S82).
