In addition, the arrow line in FIG. 2 has shown the flow of image information and audio | voice information. Moreover, the straight line without an arrow has shown the communication bus for the control part 11 to transmit / receive the control signal etc. with respect to each apparatus.

  The television apparatus 1 includes at least a control unit 11, a memory 12, an operation unit 13, a flash memory 14 (= recording unit), a broadcast receiving unit 15, an external input unit 16, an A / D conversion unit 17, a signal processing unit 18, and a D. / A conversion unit 19, audio signal output unit 20, speaker 21, image reproduction unit 22, image signal output unit 23, display 24, clock circuit 25 (= time unit), and power supply unit 26. .

  The control unit 11 controls the driving of each member of the television device 1 to control the reception of broadcast waves and the display processing of data included in the received broadcast waves. For example, the control unit 11 includes a plurality of microprocessors. Moreover, the control part 11 is provided with the EPG acquisition part 11a-acquisition control part 11e (FIG. 1) mentioned later as a function part implement | achieved by running a program on the arithmetic processing apparatus with which the control part 11 is provided.

  The memory 12 is a medium for temporarily recording various types of information held by the television apparatus 1 and is configured by, for example, a writable RAM (Random Access Memory). The memory 12 has a role as a buffer memory for temporarily recording, for example, processing information when various types of information processing are performed by the control unit 11 and instruction commands received from the user.

  The operation unit 13 is used for the user to give various instructions to the television apparatus 1 for selecting a program. The instruction output from the operation unit 13 is received by the control unit 11. The control unit 11 that has received the instruction performs channel selection processing, setting change processing, and the like based on the content of the instruction.

  The flash memory 14 is a kind of EEPROM, and is a ROM that can be written / erased by a user of the device. Since the flash memory 14 can be written / erased while being mounted on the circuit board, the flash memory 14 is used to store applications that require rewriting at the time of use, for example, device operation setting information, user-specific information, and the like. In the present embodiment, it is also used for recording EPG information and the like.

  The broadcast receiving unit 15 is connected to an external antenna (not shown), and performs digital broadcast or analog broadcast tuning, reception, frequency conversion, amplification, demodulation, and the like.

In the case of a digital system, a digital tuner, an error correction unit, and the like are included.

  The digital tuner included in the broadcast receiving unit 15 obtains TS (= transport stream), which is an MPEG2 digital signal, by amplifying and detecting the intermediate frequency signal. Note that the TS is an audio PES (Packetized Elementary Stream), an image PES, and additional information of a plurality of programs divided into fixed-length TS packets and connected. The acquired TS is given to the signal separation unit 18.

  An A / D (Analog / Digital) converter 17 converts a signal input from the broadcast receiver 15 and the external input unit 16 into a digital signal when the signal is an analog signal such as a composite signal. If the input signal is a digital signal, conversion is not performed and the input signal is output to the next signal processing unit 18 as it is.

  The signal processing unit 18 is a demultiplexing unit that receives a TS and separates it into an audio digital signal including audio information and an image digital signal including image information. Specifically, for example, the TS generated by the broadcast receiving unit 15 is divided into TS packets. Then, by recombining TS packets for each program, an audio / image PES is generated.

  Then, ES (Elementary Stream = encoded audio data, image data) is generated by combining the PES. Further, the signal processing unit 18 decodes the ES and converts it into a digital signal. The audio digital signal obtained by decoding is supplied to the D / A converter 19, and the image digital signal is supplied to the image reproducing unit 22.

  Further, the signal processing unit 18 acquires additional information such as PSI (Program Specific Information) / SI (Service Information) included in the TS.

There are also an EIT (Event Information Table) and SDT (Service Description Table) for distributing program information. The signal processing unit 18 gives the acquired data to the control unit 11.

  The D / A conversion unit 19 decodes the audio digital signal and supplies it to the audio signal output unit 20. The audio signal output unit 20 converts an audio analog signal into audio using the speaker 21 and outputs the audio. At this time, the audio signal output unit 20 sets the output volume based on the instruction received from the control unit 11.

  The image reproduction unit 22 decodes the image digital signal and supplies it to the image signal output unit 23. The image signal output unit 23 converts the given image signal into an image signal of the NTSC system or the like and displays it using the display 24. At this time, the image signal output unit 23 sets the brightness and sharpness of the output image based on the instruction received from the control unit 11.

  The clock circuit 25 is a circuit for measuring the current time, and for example, uses a crystal resonator that performs oscillation output at a predetermined frequency. The clock circuit 25 has a function of managing not only time information but also calendar information related to the calendar such as the current month and day.

The power supply unit 26 is supplied with electric power from an external power supply (not shown), and supplies a power supply voltage to each unit of the television apparatus 1. The power supply unit 26 includes, for example, a connection terminal for connecting a power cord for receiving power supply from an external power supply, a power supply circuit, and the like.
<2. About the configuration of the function section>

  Here, the relationship between the functional units for performing the EPG acquisition process in the television apparatus 1 according to the embodiment of the present invention will be described with reference to the block diagram of FIG.

  As shown in FIG. 1, the EPG acquisition process of the present invention is performed by an EPG acquisition unit 11a (= information acquisition unit), a power supply monitoring unit 11b, a startup time acquisition unit 11c, a calculation unit 11d, and an acquisition control unit 11e.

  The EPG acquisition unit 11a acquires the EPG information (= program information) for displaying the EPG by analyzing the PSI / SI acquired by the signal processing unit 18 from the TS. Specifically, EPG information is acquired using a content descriptor included in SDT, which is a type of PSI / SI. The acquired EPG information is recorded in the flash memory 14.

  The power supply monitoring unit 11b always monitors the activation state of the power supply unit 26. The power supply monitoring unit 11b determines the activation state by measuring the voltage of the power supply unit 26, for example. When the power of the power supply unit 26 is activated and power is supplied to the display 24 and the screen display is started (hereinafter referred to as “ON state”), the activation time acquisition unit 11c is detected. Make a notification.

  Note that the power supply monitoring unit 11b does not display a screen, for example, in an automatic EPG acquisition process or a scheduled recording process, when the screen display is not performed by the display 24 even if the power supply unit 26 is activated at a predetermined voltage or higher. When the process is performed, the detection notification described above is not performed to the activation time acquisition unit 11c.

  When receiving the above-described detection notification from the power supply monitoring unit 11b, the activation time acquisition unit 11c acquires the time of receiving the detection notification (hereinafter referred to as “activation detection time”) by the clock circuit 25. Then, startup time information indicating the acquired startup detection time is generated and recorded in the flash memory 14.

  The activation time acquisition unit 11c adds a new activation detection time to the activation time information every time the activation detection time is acquired, and updates the activation time information. The past activation detection time included in the activation time information may be erased when a predetermined period elapses, or may be permanently recorded without being erased.

  The calculation unit 11d calculates the distribution status of the number of times of activation detection for each time zone from the activation time information generated by the activation time acquisition unit 11c. Specifically, for example, first, a day is divided into twenty-four time zones every hour. Then, statistics on the number of activation detections per hour are taken. As for the activation detection time targeted for statistics, for example, only the activation detection time within a predetermined period such as the latest week or the last ten days may be targeted, or all past activation detection times may be targeted. Form may be sufficient.

  For example, FIG. 5 is a graph in which a day is divided into twenty-four time zones every hour, and statistics of the number of activation detections in the most recent week in each time zone are taken. In FIG. 5, the horizontal axis represents the time axis, and the vertical axis represents the number of activation detections for each time zone.

  The acquisition control unit 11e determines, based on the result calculated by the calculation unit 11d, a time zone in which the number of times of activation detection is larger than other time zones (hereinafter referred to as “frequent activation time zone”). For example, in the example of FIG. 5, 7 o'clock, 12 o'clock, and 17 o'clock when the number of activation detections exceeds a predetermined threshold is determined as the frequent activation time zone.

  Note that the threshold used for determining the frequent activation time period may be a fixed value, or may be calculated and changed as needed using a predetermined calculation formula. For example, an average value of the number of times of activation detection for each time zone may be calculated every other day, and this average value may be used as a threshold value.

  Or the form which discriminate | determines a frequent starting time slot | zone, without using a threshold value may be sufficient. For example, create a function with the number of activation detections for each time zone as an argument, and use this function to find a time zone where the number of activation detections is prominent compared to other time zones. The form to do may be sufficient.

  Furthermore, the acquisition control unit 11e determines a time or a time zone (hereinafter referred to as “acquisition timing”) for acquiring the EPG information based on the determined frequent activation time zone. When the acquisition timing arrives, an EPG information acquisition instruction is given to the EPG acquisition unit 11a.

  As a method for determining the acquisition timing, a predetermined time before the frequent activation time zone, for example, one hour before is set as the acquisition timing. For example, in the example of FIG. 5, the 6 o'clock, the 10 o'clock, and the 16 o'clock, which are one hour earlier than the 7 o'clock, 12 o'clock, and 17 o'clock, which are the frequent start times, respectively. Is determined as the acquisition timing.

<3. About EPG display screen>
Here, an EPG display screen displayed by the television apparatus 1 according to the embodiment of the present invention will be described with reference to the screen diagram of FIG.

  FIG. 4 is a screen diagram showing an example of the EPG display screen 50 displayed on the display 24. The EPG display screen 50 shown in FIG. 4 is configured to include at least an EPG part 51, a menu part 52, and a cursor 53. In the example shown in FIG. 4, the EPG unit 51 includes four channels of 4 Ch to 10 Ch and EPG for five hours from 6:00 to 10:00. On the right side of each channel column, the program name of the broadcast-scheduled program is displayed in units of time.

The user operates a remote controller (not shown) attached to the television apparatus 1 or the operation unit 13 to instruct execution of various processes included in the menu unit 52 or move the cursor 53 to execute various processes. It is possible to change the program.
<4. About EPG acquisition processing>

  Here, the EPG acquisition process by the television apparatus 1 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  FIG. 3 is a flowchart showing a processing flow of EPG acquisition processing according to an embodiment of the present invention. This process shown in FIG. 3 can be started at an arbitrary timing in a state where the standby power supply of the television apparatus 1 is driven.

  After the start of this process, the power supply monitoring unit 11b determines whether or not it is detected in step S110 that the television apparatus 1 has been turned on. If not detected, the process proceeds to step S120 described later. If detected, the activation time acquisition unit 11c acquires the time by the clock circuit 25 in step S111. Then, the acquired time is added to the activation time information recorded in the flash memory 14 as the activation detection time. If the activation time information is not recorded, the activation time information is newly created.

  Next, in step S120, the calculation unit 11d determines whether the calculation timing of the frequent activation time period has come. It is assumed that the frequent activation time zone calculation timing is determined by a fixed value or a user setting value and recorded in the flash memory 14 as setting information. For example, the frequent activation time period is periodically calculated by setting the calculation timing to midnight every day.

  When the calculation timing has not arrived, the process proceeds to step S130 described later. When the calculation timing has arrived, the calculation unit 11d reads the activation time information from the flash memory 14 in step S121. Next, in step S122, the calculation unit 11d calculates the distribution state of the number of times of activation detection for each time zone from the read activation time information (FIG. 5).

  Next, in step S123, the acquisition control unit 11e determines a frequent activation time zone from the distribution status. Further, in step S124, the acquisition control unit 11e determines the acquisition timing of the EPG information from the determined frequent activation time zone. The determined acquisition timing is recorded in the flash memory 14.

  Next, in step S130, the acquisition control unit 11e determines whether the acquisition timing has come. If the acquisition timing has not arrived, the process proceeds to step S140 described later. When the acquisition timing has come, the acquisition control unit 11e gives an EPG information acquisition instruction to the EPG acquisition unit 11a in step S131.

  Receiving this, the EPG acquisition unit 11a acquires the latest EPG information from the TS included in the digital broadcast signal. At this time, when the power supply voltage is not supplied to the broadcast receiving unit 15 and the signal processing unit 18, the EPG acquisition unit 11 a gives a power supply voltage supply instruction to the power supply unit 26. Then, after shifting to the temporary activation state, EPG information is acquired.

  Next, in step S140, the power supply monitoring unit 11b determines whether a power supply stop instruction to the power supply unit 26, that is, an instruction to turn off the main power supply is detected. When not detected, it transfers to step S110 again. When the power stop instruction is detected, the standby state cannot be maintained, and thus this process is terminated.

  According to the present embodiment described above, a time zone in which the user frequently uses the television device 1 is determined based on the past activation detection time statistics, and the EPG information is determined a predetermined time before this time zone. get. For this reason, it is possible to increase the possibility of presenting the latest EPG to the user without frequently acquiring EPG information. Accordingly, it is possible to reduce the probability that an old EPG is displayed and a discrepancy occurs between the content of the EPG and the actual broadcast program.

In addition, according to the present embodiment, the acquisition timing is determined and the EPG information is automatically acquired, so that there is no user waiting time due to the EPG information acquisition process.

  (B) In the above embodiment, the threshold value is determined by taking the average value of the number of times of activation detection for each time zone, but the threshold value may be determined by a method other than this. For example, it is possible to create a function using a graph indicating the distribution status of the number of times of activation detection as an argument and calculate the threshold value using this function. Further, the threshold value may not be fixed. For example, the day may be divided into categories such as late night, early morning, daytime, and the threshold value may be determined by a different calculation method for each category.

  (C) In the above embodiment, the number of detected activations is unconditionally counted up when the power supply unit 26 is turned on, but is counted up only when the ON state continues for a predetermined time, for example, five minutes or more. However, the count may not be increased below that.

  (D) In the above embodiment, EPG information is described as an example of data acquired at the determined acquisition timing. However, other data included in the TS may be acquired at the acquisition timing. In addition, a distribution service other than digital broadcasting may be used as a data acquisition target. For example, when the information distributed by the digital media server is targeted and the content menu distributed by the digital media server is acquired, an acquisition timing determination process and an information acquisition process may be performed.

  (E) In the above embodiment, the television apparatus 1 is taken as an example of the digital broadcast receiving apparatus, but the present invention may be implemented using a digital broadcast receiving apparatus other than this. For example, an HDD (Hard Disk Drive) recorder, DVD (Digital Versatile Disc) recorder, VCR (Video Cassette Recorder), STB (Set Top Box), or the like may be used.
