Description

  The present invention relates to a digital broadcast receiving apparatus.

  In the field of digital broadcasting, program information data (SI (Service Information: program arrangement information)) related to programs is transmitted together with broadcast program data. The program information data includes, for example, the program title, channel, genre, broadcast start time / duration, performer, program content, etc., and is displayed as an EPG (Electronic Program Guide) on the digital broadcast receiving side. It is used for program viewing reservations and recording reservations.

There is known a television receiver that receives program information data in a time zone that is not viewed by the user and performs data analysis so as not to disturb the user's viewing of the program when acquiring the program information data ( For example, see Patent Document 1.)

The decoder unit 7 includes, for example, a demultiplexer 71, a video decoder 72, an audio decoder 73, a data decoder 74, and the like.
The demultiplexing unit 71 uses the TS input from the demodulation unit 6 as a plurality of streams such as video data, audio data, PSI (Program Specific Information), and SI (Service Information: program arrangement information) as program information data. To separate.

  Here, PSI describes a PAT (Program Association Table) that describes information related to a service (organization channel) included in a TS and a PID (Packet Identifier) of the PMT, data that constitutes each service, and information related to the PID. It is a table of PMT (Program Map Table), NIT (Network Information Table) describing information related to a service being broadcast, and CAT (Conditional Access Table) describing information related to limited reception. The PSI is used when selecting a packet necessary for providing a selected program from the TS based on the PID of each packet.

In addition, the EIT includes a series identifier describing information related to the continuous program. This SI is used when displaying an electronic program guide on the display unit 11 as program information.
The control unit 13 acquires necessary TS packets based on the PSI and the PID included in each TS packet, sends a video stream under the MPEG2 (Moving Picture Experts Group 2) standard to the video decoder 72, and an audio stream. The necessary program information extracted from the SI is further output to the data decoder 74 to the audio decoder 73.

The video decoder 72 decodes the video stream input from the separation unit 71. Specifically, the video decoder 72 performs various processes such as variable-length decoding, inverse quantization, inverse DCT, motion correction, and the like on the video stream, thereby timing the video stream according to DTS (Decoding Time Stamp).

The data decoder 74 decodes the program information data, subtitle data, data broadcasting data, etc. input from the separation unit 71 and outputs each data to the control unit 13, the OSD circuit 10, and the like. The program information data input to the control unit 13 is stored in an EPG memory 134b described later.

The video processing unit 8 performs various video processes on the input video data to generate a video signal. The generated video signal is temporarily stored in a frame memory (not shown), and then output to the display unit 11 at a reproduction timing corresponding to PTS (Presentation Time Stamp).
The audio processing unit 9 performs various types of audio processing on the input audio data, generates an audio signal, and outputs the generated audio signal to the audio output unit 12 at a reproduction timing corresponding to the PTS.

  When displaying the electronic program guide, the OSD circuit 10 reads out necessary data from the program information stored in the EPG memory 134b, and generates electronic program guide display data based on the read data. Then, the generated electronic program guide display data is combined with the video signal output from the video processing unit 8, and an OSD screen such as an electronic program guide is displayed on the display unit 11.

The display unit 11 includes a display (not shown) such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or an organic EL (Electro Luminescence) display, and program content based on the video signal input from the video processing unit 8.

The audio output unit 12 includes, for example, a speaker (not shown), and outputs audio content that is program content based on the audio signal input from the audio processing unit 9 from the speaker.

  The control unit 13 includes a CPU (Central Processing Unit) 131, a timekeeping unit 132 such as an STC (System Time Clock), a volatile memory such as a RAM (Random Access Memory) 133, an EEPROM (Electrically Erasable Programmable ROM) 134, a ROM (Read Only Memory) 135 and the like are provided.

  The CPU 131 executes various programs stored in the ROM 135 in accordance with input signals input from the respective units of the main body unit 2, remote control signals input by pressing the buttons on the remote control device 1, and the like. The overall operation of the television receiver 100 is comprehensively controlled by outputting an output signal to each part of the main body 2 based on the program.

  The timekeeping unit 132 measures time and date and creates date / time data. Note that the time data and the like timed are sent to the RAM 133 via the CPU 131 and sequentially updated.

  The RAM 133 is used as a work area for the CPU 131, and temporarily stores processing results generated when various programs are executed by the CPU 131, input data, and the like.

The EEPROM 134 includes, for example, a setting memory 134a, an EPG memory 134b, and the like.
The setting memory 134a is set by the television receiver 100 (main unit 2) from the display unit 11 or the audio output unit 12 with respect to, for example, a good morning timer set in the execution of a startup date / time setting program 135c described later. It stores start date / time data at the timing to be started in order to output content, channel data of a broadcast station selected at the start, and the like.
In the setting memory 134a, data related to the time required to receive the program information data, for example, required time data for receiving the program information data for 8 days for all stations, and the program information data for 1 day for all stations on the day. The required time data for receiving the program information data, the required time data for receiving the program information data for 8 days for each station, and the like are stored.
The EPG memory 134b stores program information data extracted from the received broadcast signal.

  The ROM 135 has a program storage area composed of a nonvolatile memory. Specifically, the ROM 135 includes a reception program 135a, a content output program 135b, a start date / time setting program 135c, a start control program 135d, a program information acquisition control program 135e, and the like. Storing.

The reception program 135a is a program for causing the CPU 131 to realize a function of receiving a broadcast signal in which program content and program information are multiplexed, for example.
Specifically, the CPU 131 monitors a user's instruction operation on the remote control device 1 based on a remote control signal input via the remote control signal light receiving unit 3. When a channel selection operation is performed in the remote control device 1, the CPU 131 outputs an instruction signal to the tuner 5, and the frequency associated with the channel selected from the broadcast signal input to the antenna 4. The broadcast signal of the band is received.
By executing the reception program 135a, the CPU 131 functions as a receiving unit together with the tuner 5 and receives a broadcast signal including broadcast program data and program information data.

For example, the content output program 135b displays the video content of the program content based on the broadcast program data in the broadcast signal received via the tuner 5 on the display unit 11 (display), and the audio of the program content based on the broadcast program data. This is a program for realizing a function of outputting content from the audio output unit 12 (speaker).
The CPU 131 functions as a content output unit together with the display unit 11 and the audio output unit 12 by executing the content output program 135b.

The activation date / time setting program 135c stores, in the EEPROM 134, activation date / time data related to the date and time for starting the television receiver 100 (main unit 2) and channel data to be selected at the time of activation, for example, at a timing desired by the user. This is a program for realizing the function to be performed.
Specifically, the start date and time data and the channel data input via the operation unit of the remote control device 1 are input to the control unit 13 (CPU 131) through the remote control signal light receiving unit 3 of the main body unit 2, thereby starting the start date and time. Data and channel data are stored in the setting memory 134 a of the EEPROM 134.
The CPU 131 functions as an activation date setting unit together with the EEPROM 134 by executing the activation date setting program 135c.

For example, the activation control program 135d causes the display unit 11 and the audio output unit 12 to output program content (video content, audio content) according to the channel data at a preset date and time based on the activation date and time data stored in the EEPROM 134. As described above, this is a program for realizing a function of starting up the television receiver 100 (main unit 2).
The CPU 131 functions as an activation control unit that activates the television receiver 100 (main unit 2) from off to on at a date and time desired by the user by executing the activation control program 135d. Note that the CPU 131 as the activation control unit also has a function of determining whether activation date / time data is stored in the EEPROM 134 during standby of the television receiver 100 (main unit 2).

The program information acquisition control program 135e includes program information data by the tuner 5 or the like that is a predetermined time required to receive the program information data from the activation time corresponding to the activation date and time data stored and set in the EEPROM 134. It is a program for realizing the function of starting reception of broadcast signals and acquiring program information.
Specifically, the CPU 131 receives program information rather than the startup time so that the acquisition of the program information is completed before the television receiver 100 (main unit 2) is started at the set startup time. Program information via the tuner 5 earlier (for example, the time corresponding to the required time data for receiving the program information data for all eight stations stored in the setting memory 134a, for example, 20 minutes). Start receiving broadcast signals containing data.
By executing the program information acquisition control program 135e, the CPU 131 starts reception of a broadcast signal including program information data earlier by a predetermined time prior to activation of the television receiver 100 (main unit 2). It functions as a program information acquisition control means for acquiring program information until the John receiver 100 (main unit 2) is activated. The CPU 131 serving as the program information acquisition control means starts receiving the broadcast information including the program information data based on the start time corresponding to the start date and time data and the required time corresponding to the required time data. It also has a function for calculating time.

In particular, the CPU 131 as program information acquisition control means acquires the program information of the day corresponding to the set date and time with priority over other program information (program information of the later day), and then the programs for 8 days for all stations. Control for receiving a broadcast signal including program information data is executed so as to acquire information. According to this control, immediately before the timer is started, when a user who has not waited for the start-up has manually turned on the television receiver 100 (main unit 2), at least that day. The possibility that the acquisition of the program information is completed can be increased, and the program can be viewed for the time being.
Further, the CPU 131 as the program information acquisition control means acquires the program information of a preset channel in preference to the program information of other channels, and then acquires the program information for all stations for eight days. Control for receiving a broadcast signal including program information data is executed. According to this control, when a user who has not waited for the activation of the timer has manually turned on the television receiver 100 (main unit 2) immediately before the activation of the timer, at least a desired channel. The possibility that the acquisition of the program information is completed can be increased, and the program can be viewed for the time being.
In addition, about the acquisition of the program information of the day with priority and the acquisition of the program information of a preset channel with priority, the setting is made when the user desires, and the priority acquisition condition setting data is set. As long as it is stored in the setting memory 134a or the like.

  Further, the CPU 131 as program information acquisition control means usually receives a broadcast signal including program information data via the tuner 5 during a time period when the user is not viewing the program, and acquires or updates the program information. To do. That is, the program information of the current day and the program information of a preset channel are preferentially acquired, but if the acquisition of all program information is incomplete, it is determined at a time zone when the user is not viewing the program. Program information is sequentially acquired in order (for example, broadcast station order, date order, etc.), and program information for 8 days is acquired for all stations.

  Next, the flow of program information acquisition processing performed in the television receiver 100 of this embodiment will be described with reference to the flowchart of FIG.

During the standby of the television receiver 100 (main unit 2), the CPU 131 is set with respect to the activation date and time such as a good morning timer, and whether or not the activation date and time data for starting up the television receiver 100 is stored in the EEPROM 134. Is determined (step S101).
Note that the CPU 131 may determine the presence / absence of activation date / time data when the television receiver 100 (main unit 2) is switched to the standby state, and the activation date / time data is input (timer setting). It may be determined that the start date / time data is stored.

When the CPU 131 determines that the start date / time data is stored (step S101; Yes), the CPU 131 calculates a program information acquisition start time (step S102).
For example, when the start time according to the start date and time data set by the timer is “AM 6:30” and the time required for receiving the program information data for all stations for 8 days is “20 minutes”, the program information The acquisition start time is calculated as “AM 6:10”. The calculated program information acquisition start time data is stored in the setting memory 134a.
The program information acquisition start time is not limited to the time required for receiving the program information data from the start time “AM 6:30”, but the required time (20 minutes) and the preliminary time (10 minutes) are added together. The predetermined time (30 minutes) may be set earlier (in this case, the program information acquisition start time is calculated as “AM 6:00”).

Next, the CPU 131 determines whether or not the program information acquisition start time has come (step S103).
When the CPU 131 determines that the program information acquisition start time has come (step S103; Yes), the CPU 131 causes the broadcast signal to be received via the tuner 5, decodes the program information data in the broadcast signal, and displays the program information. Data is stored in the EPG memory 134b and acquired (step S104). And acquisition of program information data is continued until it becomes starting time.

Next, the CPU 131 determines whether or not the activation time has come (step S105).
When the CPU 131 determines that the activation time has come (step S105; Yes), the CPU 131 activates the television receiver 100 (main unit 2) and is based on broadcast program data in a broadcast signal received via the tuner 5. Program content (video content, audio content) is output from the display unit 11 or the audio output unit 12 (step S106).

The television receiver 100 (main unit 2) activated in this way can change the channel, volume, etc. as desired by the user in response to an operation using the remote control device 1 by the user, so that the broadcast program can be viewed. It becomes possible.
In particular, when the television receiver 100 (main unit 2) is activated, all program information data is surely acquired, and program information data for all stations for eight days is stored in the EPG memory 134b. It is possible to view programs and make quick recording reservations.
If the program information acquisition start time is set earlier than the start time by a predetermined time that is the sum of the time required to receive the program information data and the preliminary time, a margin for the preliminary time will be generated. Even when an error that increases the time required to receive information data occurs or when an error occurs in the timing unit 132, all program information can be acquired more reliably. become.

  As described above, the television receiver 100 according to the present invention, when a setting related to the start date and time, such as a good morning timer, is performed, is a predetermined time earlier than the start time at the start date and time of the broadcast signal including the program information data. By starting reception, all program information can be reliably acquired by the time the television receiver 100 is activated. Therefore, when the television receiver 100 is activated, programs for all stations of 8 days are obtained. Information data is stored in the EPG memory 134b, and suitable program viewing and prompt recording reservation can be performed immediately after startup.

In particular, since the latest program information can be acquired immediately before the television receiver 100 is activated, unnecessary broadcast signal reception processing during standby can be omitted.
That is, when the user sets the time for starting up the television receiver 100 by a good morning timer or the like, the user does not watch the program until the startup time is reached, so the program information is displayed when the television receiver 100 is started up. It is only necessary to acquire the broadcast signal, and it is not necessary to repeat the reception of the broadcast signal in order to acquire the program information in the standby television receiver 100 (conventionally, every two to three hours during standby such as midnight) In addition, broadcast signals have been received to obtain program information.) Further, during the setting of the good morning timer, it is a time zone in which the user does not watch the program, so that the broadcast signal including the program information data can be reliably received.
If the television receiver 100 can acquire the latest program information immediately before the timer is started, the unnecessary broadcast signal reception process during standby can be omitted. There is an advantage that the power consumption required for the receiving process can be reduced.

The scope of the present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the present embodiment, the television receiver 100 has been described as an example of a digital broadcast receiving apparatus, but an STB (Set Top Box) or the like may be used, for example.
Further, in the television receiver 100 of the present embodiment, the configuration in which the program content can be recorded in the recording device connected to the main body unit 2 has been described. For example, the recording such as the HDD built in the television receiver 100 is possible. It may be possible to record program content on a medium. Moreover, the structure which does not record a program content may be sufficient.
