[0029]
A predetermined command can be directly input to the CPU 29 by operating various keys (FIG. 2) on the front panel 40. When the remote commander 6 (FIG. 4) is operated, an IR signal is emitted from the IR signal transmission unit 72, the IR signal is received by the IR signal reception unit 54, and the light reception result is supplied to the CPU 29. Accordingly, a predetermined command can be input to the CPU 29 also by operating the remote commander 6.
[0030]
Further, the demultiplexer 24 takes in EPG (Electrical Program Guide) data and the like in addition to the MPEG video data and audio data supplied from the front end 20 and supplies them to the EPG area 35A of the data buffer memory 35 for storage. EPG information is information about programs of each broadcast channel up to 24 hours after the current time (in the case of EPG2 and EPG1-2) or 150 hours later (in the case of EPG2, EPG3, EPG1-2, and EPG1-3) (for example, In addition to the still image of the program, channel, broadcast time, title, category, etc.) are included. Since this EPG information is frequently transmitted, the latest EPG can always be held in the EPG area 35A.
[0031]
In an EEPROM (Electrically Erasable Programmable Read Only Memory) 38, data to be retained even after the power is turned off (for example, the setting contents of the reception setting, the reception history for four weeks of the tuner 21, immediately before a predetermined operation is performed) The received channel number (last channel)) is stored as appropriate. This memory is used, for example, when the same channel as the last channel is received again when the power is turned on. When the last channel is not stored, the channel stored as a default in the ROM 37 is received.
[0032]
In addition, when the sleep mode is set, the CPU 29 sets the minimum circuits such as the front end 20, the demultiplexer 24, and the data buffer memory 35 to the operating state even when the power is off, and sets each circuit at a predetermined time. Control for causing the circuit to perform a predetermined operation is also executed. For example, timer automatic recording is executed in conjunction with an external VCR.
[0033]
Furthermore, the CPU 29 controls the MPEG video decoder 25 when it is desired to generate predetermined OSD (On-Screen Display) data. In response to this control, the MPEG video decoder 25 generates predetermined OSD data, writes it to the OSD area of the DRAM 25a, reads it out, and outputs it. As a result, predetermined characters, figures, images, and the like can be appropriately output to the television receiver 3 for display.
[0034]
The SRAM 36 is used as a work memory for the CPU 29. The modem 34 exchanges data via a telephone line under the control of the CPU 29.

The volume up / down key 93 is operated when the volume is increased or decreased by a certain amount.
[0041]
Here, a specific processing operation of the IRD 2 will be described with reference to a flowchart of FIG.
[0042]
When the IRD 2 and the television receiver 3 are turned on in step S1 of FIG. 5, the CPU 29 of the IRD 2 determines whether or not reception setting information is stored in the EEPROM 38 in a subsequent step S2.
[0043]
When it is determined that the reception setting information is stored in the EEPROM 38, the process branches to step S7. However, when it is determined that the reception setting information is not stored in the EEPROM 38, in the subsequent step S3, the CPU 29 The reception setting screen data stored in the ROM 37 is read and output to the television receiver 3 via the MPEG video decoder 25, the NTSC encoder 27, and the buffer amplifier 28V.
[0044]
An example of a display screen displayed on the monitor of the television receiver 3 at this time is shown in FIG. As shown in FIG. 6, a message prompting the user's operation is displayed on the monitor of the television receiver 3 together with the characters “reception setting” representing the reception setting screen.
[0045]
Next, in step S4, the user performs an operation for reception setting according to the display of the reception setting screen. Specifically, according to the message displayed on the screen of FIG. 6, when the user presses the enter key 92 of the remote commander 6, the corresponding instruction signal is supplied to the CPU 29 via the IR signal receiving unit 54. . In response to this instruction signal, the CPU 29 reads the data of the screen next to the screen shown in FIG. 6 from the ROM 37 and sends it to the television receiver 3 via the MPEG video decoder 25, the NTSC encoder 27, and the buffer amplifier 28V. Output.
[0046]
A display example of the screen thus displayed on the monitor of the television receiver 3 is shown in FIG. The screen shown in FIG. 7 is a screen for inputting or selecting detailed information of reception settings.
[0047]
The user operates the left key 90 and the right key 91 of the remote commander 6 to select one of the areas A1 to A3, thereby specifying the supply source of the voltage supplied to the converter (LNB1a). can do. That is, when a vertically polarized or horizontally polarized television signal is received, the region A1 is designated if a voltage of 15 V or 11 V is supplied from the IRD 2 to the converter (LNB 1a), respectively. In addition, if a voltage having a fixed value of either 15V or 11V is supplied from the IRD2 to the converter (LNB1a), the area A2 is designated, and the power supply other than the IRD2 is installed in, for example, an apartment. If a voltage is supplied to the converter (LNB 1 a) from a predetermined power source for common listening, the area A 3 is designated. Note that the designated (selected) area is displayed differently from the other areas (non-designated areas). That is, the screen shown in FIG. 7 shows a state in which the area A1 is designated.
[0048]
Similarly, the user can designate the frequency of the converter (LNB 1a) by operating the remote commander 6 and selecting or inputting data to the areas A4 to A8. That is, if the converter (LNB1a) having a local oscillation frequency of 11.2 GHz is used, the area A4 is specified. If the converter (LNB1a) having a local oscillation frequency of 11.3 GHz is used, the area A5 is specified. To do. For example, if a common antenna such as an apartment is used, the area A8 is designated. When using another frequency converter (LNB 1a), the area A6 is designated and a predetermined frequency is input to the area A7 by operating the numeric keypad 81 of the remote commander 6.
[0049]
When the input of the setting screen shown in FIG. 7 is completed, the user designates the area A9 (antenna setting) and causes the next setting screen (antenna setting screen) to be displayed by pressing the enter key 92 or the area A9 (end) is designated to end the reception setting process.
[0050]
When the user designates the area A9 (antenna setting) and presses the enter key 92, it is determined whether or not the reception setting is completed in step S5. In this case, NO is determined in this step. The process of step S4 is executed. That is, in response to this operation, the CPU 29 reads data on the screen (antenna setting screen) next to the screen shown in FIG. 7 from the ROM 37, and passes through the MPEG video decoder 25, the NTSC encoder 27, and the buffer amplifier 28V. And output to the television receiver 3.
[0051]
A display example of the screen thus displayed on the monitor of the television receiver 3 is shown in FIG. The screen shown in FIG. 8 is a screen for inputting or selecting detailed information of antenna settings.
[0052]
In the area A12, the frequency of the television signal that can be received first among the television signals assigned to the eight transponders of the broadcasting satellite is automatically displayed. Then, the network name of the television signal included in the received NIT (Network Information Table) is displayed in the area A11.
[0053]
In the area A13, the signal level of the received television signal is represented in 35 levels as a peak level (maximum level so far) and a cue level (current level). That is, the example of the screen shown in FIG. 8 indicates that the cue level is a signal level represented by 30 in 35 stages and the peak level is a signal level represented by 33 in 35 stages. Therefore, referring to the signal level in the region A13, the antenna is installed in the direction in which the signal level is highest.
[0054]
When manually receiving a television signal assigned to another transponder, the area A15 (satellite frequency switching) is designated. If the area A14 (return) is designated, the screen immediately before the antenna setting screen shown in FIG. 8, that is, the reception setting screen shown in FIG. 7 can be displayed. When the area A16 (end) is designated, the reception setting process ends. In this way, by designating any one of the areas A14 to A16 and pressing the enter key 92, the designated process is executed. In the screen shown in FIG. 8, area A16 (end) is designated.
[0055]
When the user presses the enter key 92 in the state shown in FIG. 8 (state in which the area A16 is specified), a determination of YES is made in step S5, and in the next step S6, the CPU 29 displays the reception setting screen (FIG. 7). And the information input or selected in FIG. 8) is stored in the EEPROM 38.
[0056]
In the subsequent step S 7, when the user operates, for example, the numeric keypad 81 of the remote commander 6 to input a predetermined channel number, an IR signal corresponding to the input number is output from the IR signal transmission unit 72. This IR signal is received by the IR signal receiver 54 of the IRD2. When receiving a signal corresponding to the IR signal from the IR signal receiving unit 54, the CPU 29 controls the tuner 21 to receive the channel corresponding to the input number.
[0057]
The tuner 21 demodulates the signal corresponding to the channel number designated by the CPU 29 from the signal supplied from the LNB 1 a and outputs the demodulated signal to the QPSK demodulation circuit 22. The signal QPSK demodulated by the QPSK demodulator 22 is further input to the error correction circuit 23, subjected to error correction processing, and then input to the demultiplexer 24. In the demultiplexer 24, the input data is separated into video data and audio data, and the video data is supplied to the MPEG video decoder 25 and the audio data is supplied to the MPEG audio decoder 26, respectively. The MPEG video decoder 25 decodes the input video data by the MPEG method and then outputs it to the NTSC encoder 27. The NTSC encoder 27 converts the input video data into an NTSC video signal. This video signal is supplied to the television receiver 3 via the AV line 4 as a composite video signal via the buffer amplifier 28V, for example.
[0058]
Also, the MPEG audio decoder 26 decodes the input audio data by the MPEG method and outputs it to the D / A converter 30. The D / A converter 30 performs D / A conversion on the input audio data, and outputs it as left and right analog audio signals via the buffer amplifiers 31L and 31R. This audio signal is also output to the television receiver 3 via the AV line 4. In this way, the image and sound of the program instructed by the user operating the remote commander 6 are output to the television receiver 3.
[0059]
Further, when the demultiplexer 24 detects EPG data from the received signal, the demultiplexer 24 supplies this to the data buffer memory 35 and stores it in the EPG area 35A.
[0060]
When a predetermined key of the remote commander 6 is operated to read out the EPG information, the CPU 29 reads out the EPG data stored in the EPG area 35A and converts it into the MPEG video decoder 25 and converts it into OSD data. Let The OSD data is output to the NTSC encoder 27, and is superimposed on an image of a normal program and output.
[0061]
That is, when the television signal received by the LNB 1a is supplied to the demultiplexer 24 via the tuner 21, the QPSK demodulation circuit 22, and the error correction circuit 23, the demultiplexer 24 displays the video of the television program designated by the user. The signal and the audio signal are output to the MPEG video decoder 25 or the MPEG audio decoder 26, respectively. The video signal is output to the television receiver 3 via the NTSC encoder 27 and the video terminals Y and C, and the audio signal is transmitted to the television receiver 3 via the D / A converter 30 and the audio terminals L and R. Is output.
[0062]
In this way, information necessary for receiving a television signal can be set.
[0063]
In addition, when the information necessary for reception is not set, for example, when the IRD 2 and the television receiver 3 are turned on for the first time after purchase, a reception setting screen as shown in FIG. 6 is automatically displayed. Therefore, it is not necessary for the user to perform an operation for calling up the reception setting screen, and the reception setting process can be started quickly.
[0064]
In the above embodiment, the case of satellite broadcasting has been described. However, the present invention can also be applied to reception settings for television signals transmitted via terrestrial waves or predetermined cables.
[0065]
【The invention's effect】
As described above, according to the television signal receiving device of the first aspect, it is determined whether or not information for receiving a television signal is set when the power is turned on, and in response to the determination result, Since a setting screen for setting information is displayed, reception setting can be started quickly.
