Therefore, when the user receives a television signal, it is considered that the user is watching while processing information using a personal computer. Is considered practical.

Next, the processing of the CPU 10 relating to television reception will be described with reference to FIG. When a television receiving mode instruction signal is given from the keyboard unit 13 via the keyboard controller 14, the CPU 10
Starts the processing shown in FIG. 7, and first displays the television operation image OPPIC shown in FIG. 6 on the CRT unit 16 (step 100). Then, the input signal from the keyboard unit 13 or the mouse 15 is awaited, and when the input signal is given, the type is discriminated (steps 101 and 102). It should be noted that in this determination, the suitability of the input signal is also determined, and the process proceeds to the following process only when it is appropriate. For example, when the television receiving function is not in the power-on state, the following power-off processing is not executed even if the power-off input of the television receiving function is made. In this case, the state returns to the input waiting state. ..

If the movement input of the mouse cursor MC,
The mouse cursor MC is moved and displayed again to return to the input waiting state (step 103).

In the case of power-on input for the television receiving function, first, a window TVWIN for displaying a video signal in the television signal is opened to make the video signal displayable or the audio signal soundable. Then, the channel at the previous power-off time is taken out from the memory 12, the channel selection data is taken out from the ROM 11 and given to the television signal processing unit 22 via the television control data conversion means 23. , The volume data at the time of the previous power-off is taken out from the memory 12, given to the speaker controller 19, and returned to the input waiting process (step 104-).

11 to take out from the television control data conversion means 2
After the signal is supplied to the television signal processing unit 22 via 3, the process returns to the input waiting process (steps 108 and 109).
At this time, the television signal processing unit 22
Select the updated channel. If there is a channel up input when the current channel is the maximum value channel, the CPU 10 sets the minimum value channel as a new channel in the process of step 108.

When the channel down input is given, the CPU 10 retrieves the current channel from the memory 12, recognizes a new channel (basically, a channel smaller than the current channel by one), and updates the storage channel, ROM for channel tuning data
11 to take out from the television control data conversion means 2
After being given to the television signal processing unit 22 via 3, the process returns to the input waiting process (steps 110 and 111).
Also at this time, the television signal processing unit 22 selects the updated channel. If there is a channel down input when the current channel is the minimum value channel, the CPU 10 sets the maximum value channel as a new channel in the processing of step 110.

When the volume up input is given, the CPU 10 takes out the present volume data from the memory 12 and updates the volume data by one unit larger than that, and after giving this volume data to the speaker controller 19,
The process returns to the input waiting process (steps 112 and 113). At this time, the speaker controller 19 adjusts the audio signal from the television signal processing unit 22 according to the volume data. When the volume up input is made when the current volume data is the maximum value, the CPU 10
Maintains the volume data in the process of step 112.

When the volume down input is given, the CPU 10 takes out the current volume data from the memory 12 and updates the volume data by one unit smaller than that, and after giving this volume data to the speaker controller 19,
The process returns to the input waiting process (steps 114 and 115). Also at this time, the speaker controller 19 adjusts the audio signal from the television signal processing unit 22 according to the volume data. If there is a volume down input when the current volume data is the minimum value, the CPU 10
Maintains the volume data in the processing of step 114.

When there is an input other than the above, the CPU 10 performs a process according to the input and returns to the input waiting process (step 116).

Next, a user's operation relating to the television receiving function will be described. When the user desires to watch a television program, the user operates the keyboard unit 13 to instruct the television reception mode. As a result, the television operation image OPPIC is displayed on the CRT unit 16. Here, the mouse 15 is operated to position the mouse cursor MC on the power-on switch icon PWON, and the mouse 15 is clicked. As a result, the video signal window TVWIN of the television signal is opened to display the video signal of the channel at the previous power-off time, and the audio signal of the channel is sound-outputted.

Next, the processing of the CPU 10 relating to radio reception will be described with reference to FIG. When a radio reception mode instruction signal is given from the keyboard unit 13 via the keyboard controller 14, the CPU 10 starts the processing shown in FIG. 10, and first causes the CRT unit 16 to display the radio operation image OPPICR shown in FIG. (Step 200). Then, the input signal from the keyboard unit 13 or the mouse 15 is waited for, and when the input signal is given, the type is discriminated (steps 201, 20).
2). It should be noted that in this determination, the suitability of the input signal is also determined, and the process proceeds to the following process only when it is appropriate.

If it is a movement input of the mouse cursor MC,
The mouse cursor MC is moved and displayed again to return to the input waiting state (step 203).

If the power-on input of the radio reception function is made, the sound signal is first made audible, then the tuning frequency data at the previous power-off time is taken out from the memory 12, and the tuning frequency data is set to the radio control data. It is given to the radio signal processing unit 42 via the converting means 43, and the volume data at the previous power-off time is taken out from the memory 12 and given to the speaker controller 19, and the process returns to the input waiting process (steps 204 to 206).
At this time, the radio signal processing unit 42 tunes to the given tuning frequency and then performs demodulation processing, and gives the obtained audio signal to the speaker controller 19 to output sound. At this time, the speaker controller 19
Adjust the audio signal to the volume indicated by the given volume data.

When the input is the power-off input of the radio receiving function, the CPU 10 performs the processing for ending the sound generation of the audio signal from the radio signal processing unit 42 and returns to the above-described input waiting processing (step 207).

When the tuning frequency up input is given, the CPU 10 fetches the tuning frequency data at the present time from the memory 12 and updates the tuning frequency data by one unit larger than the tuning frequency data, and this data is converted into the radio control data converting means 43. After the signal is supplied to the radio signal processing unit 42 via the, the process returns to the input waiting process (steps 208 and 209).
At this time, the radio signal processing unit 42 tunes to the tuning frequency. When the tuning frequency up input is made when the current tuning frequency data is the maximum value, the CPU 10 maintains the tuning frequency data in the process of step 208.

When a down input of the tuning frequency is given, the CPU 10 takes out the tuning frequency data at the present time from the memory 12 and updates it to tuning frequency data smaller by one unit than the tuning frequency data, and this data is converted into the radio control data converting means 43. After the signal is supplied to the radio signal processing unit 42 via the, the process returns to the input waiting process (steps 210 and 211).
Also at this time, the radio signal processing unit 42 tunes to the tuning frequency. When the tuning frequency down input is made when the current tuning frequency data is at the minimum value, the CPU 10 maintains the tuning frequency data in the process of step 210.

Since the processing when the volume up input or the volume down input is given is almost the same as that of the first embodiment,
The description is omitted (steps 212 to 215).

When there is an input other than those described above, the CPU 10 performs a process according to the input and returns to the input waiting process (step 216).
