  The transmitted television broadcast signal is received again by the antenna 90 via the public line network 98 and the base station 97, and this received signal is transmitted to the RF unit via the switching unit 92 switched to the receiving side. 94 is converted to an intermediate frequency and input to the baseband processing unit 96 for baseband processing.

  In the baseband processing unit 96 of the present embodiment, a signal corresponding to the reception strength (RSSI: Received Signal Strength Indicator) of the reception signal is output to the reception signal monitoring unit 80. The signal corresponding to the reception intensity, and the reception level corresponding to the preset reception intensity necessary for displaying a sufficient video stored in the reception signal monitoring unit 80 or the storage unit 85 of the personal computer function unit 83 Are compared by the received signal monitoring unit 80.

  By comparing each of the S / N ratio and the reception intensity in the reception signal monitoring unit 80, it is determined whether or not the reception status of each of the television broadcast reception unit 70 and the W-CDMA transmission / reception unit 91 can display a sufficient video. Yes (step 325).

  If the S / N ratio of the television broadcast receiver 70 is larger than a predetermined S / N ratio (YES in step 325), it is determined whether or not the W-CDMA transceiver 91 is connected to the line. However (step 330), when connected (YES in step 330), the communication of the W-CDMA transceiver 91 is disconnected (step 335). On the other hand, when the W-CDMA transmission / reception unit 91 is not connected (NO in step 330) and when the W-CDMA transmission / reception unit 91 is disconnected in step 335, the switching signal is switched from the reception signal monitoring unit 80. The signal is sent to the circuit 82, the contact C and the contact A are connected (step 340), and further, a power control signal is sent from the received signal monitoring unit 80 to the MPEG decoding unit 76 of the television broadcast receiving unit 70 to supply power. On the other hand, a power control signal is sent to the baseband processing unit 96 to stop the power supply.

  The video signal from the MPEG decoding unit 76 is output to the personal computer function unit 83 via the contact point AC of the switching circuit 82 and displayed on the display unit 86 via the signal processing unit 84 (step 370). Note that the signal processing unit 84 can also perform various signal processing on the video signal. For example, the video signal may be processed by the personal computer function unit 83 so that the video display size is matched to the size of the display unit 86 or a partial frame of the video is stored.

  On the other hand, when the S / N ratio output from the television broadcast receiving unit 70 to the received signal monitoring unit 80 is equal to or lower than the predetermined S / N ratio (NO in step 325), the power consumption is reduced. Then, the operation is stopped based on the power control signal of the MPEG decoding unit 76 of the television broadcast receiving unit 70 (step 350), and the switching circuit 82 is connected to the contact B and the contact C on the W-CDMA transmission / reception unit 91 side based on the reception status signal.

  Thereafter, a line connection is established between the W-CDMA transmission / reception unit 91 and a predetermined telephone number, and a television broadcast signal is received from the telephone number via the communication line (step 360). Then, the television broadcast video of the desired channel is displayed on the display unit 86 via the switching circuit 82 and the signal processing unit 84 (step 370).

  Next, when the television broadcast reception is ended (when YES in step 375), for example, when the television broadcast is being displayed or when a desired program is terminated, the television broadcast reception unit 70, the W-CDMA transmission / reception unit 91 is completed. Is stopped (step 380), and the process returns to step 305 to determine whether or not the TV broadcast receiving software is to be started. If NO, the process returns to step 350 and the TV broadcast receiving software is started again. Wait.

As described above, in the first embodiment, when the reception level at the television broadcast receiving unit 70 becomes a desired level or less, the television broadcast receiving unit can be automatically switched to the television broadcast indirect receiving means. Therefore, it is possible to watch the television broadcast that you want to watch with less interruption. Further, in the first embodiment, since the television broadcast receiving function is installed in the notebook computer, the television broadcast can be viewed even outdoors. In addition, a display unit 86 such as a monitor or the like can be used depending on the reception status of a method of directly receiving a television broadcast by the television broadcast receiver 70 and a method of indirectly receiving the television broadcast by the W-CDMA transceiver 91 via the public network. Therefore, even when the viewer is moving, the information processing apparatus 100 can view the television broadcast. For video transfer by telephone line connection, Internet transfer may be used in addition to the video phone system.

  In this embodiment, the power supply to the W-CDMA transmission / reception unit 91 is stopped in step 335. However, even when the television broadcast reception unit 70 is receiving data, the power transmission to the W-CDMA transmission / reception unit 91 is performed. The reception signal monitoring unit 80 may be configured to receive reception signals from each of the television broadcast reception unit 70 and the W-CDMA transmission / reception unit 91 and to continue monitoring the reception status.

  By configuring in this way, for example, when a viewer is receiving a television broadcast while riding, and when the reception status at the television broadcast receiving unit 70 deteriorates due to the influence of a building or the like while moving, The reception signal monitoring unit 80 can detect that the reception signal level is equal to or lower than a predetermined level, and stops supplying power to the MPEG decoding unit 76 and sends a switching signal to the switching circuit 82 to connect the switching circuit 82. Are switched between B and C, and the received signal of the desired television broadcast quickly received by the W-CDMA transmission / reception unit 91 is processed by the baseband processing unit 96, and the processed video signal is passed through the switching circuit 82 to the signal processing unit. It can be displayed on the display unit 86 via 84.

  Next, a second embodiment will be described with reference to FIGS. FIG. 5 is a diagram showing a schematic configuration of the second embodiment. In the information processing system 2000, a portion surrounded by a dotted line is the information processing apparatus 200, and FIG. 6 receives a television broadcast in the second embodiment. It is a figure which shows the principal part of the processing flow in the case of doing. In the second embodiment, components having the same or similar functions as those in the first embodiment are denoted by the same reference numerals.

  The information processing apparatus 200 in the second embodiment includes a television broadcast receiving unit 70 that is a TV receiving module and a wireless LAN module 161 in a portable information processing apparatus 200 such as a notebook personal computer. It is a thing. Unlike the first embodiment, the wireless LAN module 161 capable of accessing a private line or the like is mounted on the television broadcast indirect receiving means, which is different from the first embodiment.

  Next, this embodiment will be described with reference to FIGS. Also in the second embodiment, the information processing apparatus 200 is turned on in the initial state, and no power is supplied to the television broadcast receiving unit 70 and the wireless LAN module 161 (step 500). In this initial state, next, TV reception software installed in the storage unit 85 of the personal computer function unit 83 is activated (in the case of YES in step 505). When this software is activated, the signal processing unit 84 starts supplying power to the television broadcast receiving unit 70 and the wireless LAN module 161. The channel information of the desired television broadcast and the address of the other party that communicates via the wireless LAN module 161 are input from the input unit 87 (step 515).

  The channel selection signal corresponding to this channel information is sent to the tuner unit 72 of the television broadcast receiving unit 70, and the television broadcast signal of the selected channel is output to the baseband processing unit 74. From the baseband processing unit 74, A BER indicating the reception status of the received television broadcast signal is output to the reception signal monitoring unit 80 and compared with a predetermined level for the reception signal stored in the storage unit 85 of the personal computer function unit 83 as in the first embodiment. Then, it is determined whether or not the television broadcast signal received by the television broadcast receiving unit 70 is at a reception level sufficient to display a good video (step 525).

  If the received television broadcast reception signal is at a sufficient level (YES in step 525), it is determined whether or not the wireless LAN module 161 is connected to the other party, and if it is connected (in step 530). If YES, the wireless LAN module 161 is disconnected (step 535). On the other hand, if the wireless LAN module 161 is not connected (NO in step 530), the wireless LAN module 161 does not receive a television broadcast signal, so that power is supplied to the baseband processing unit 166 of the wireless LAN module 161. And switching the connection of the switching circuit 82 to the connection between A and C (step 540). Further, the power supply to the MPEG decoding unit 76 is started, and the desired channel output from the MPEG decoding unit 76 is switched. The video signal of the television broadcast is displayed on the display unit 86 via the switching circuit 82 and the personal computer function unit 83.

  On the other hand, when the reception signal monitoring unit 80 determines that the reception level received by the television broadcast reception unit 70 in step 525 is lower than a predetermined level (NO in step 525), the reception signal monitoring unit 80 transmits the television broadcast. A power control signal is sent to the receiving unit 70, and the power supply to the MPEG decoding unit 76 is stopped (step 550).

  Then, the contact point of the switching circuit 82 is set as a B-C connection, and the wireless LAN module 161 and the signal processing unit 84 are connected (step 555) and input from the input unit 87 of the signal processing unit 84 or already stored in the storage unit 85. Is transmitted to the baseband processing unit 166 of the wireless LAN module 161 and transmitted by the RF unit 164. The signal is converted into a wave and transmitted from the antenna 160 via the switching unit 162 switched to the transmission side. This transmission signal is received by the transmitter / receiver 167 installed on the ceiling of the building, for example, and is received by the remote terminal device 169 identified by the transmission destination address via the cable 168 that is a LAN line. The television broadcast reception function of the remote terminal device 169 receives a television broadcast of a desired channel, and transmits the television broadcast signal of this channel to the information processing device 200 included in the transmission information. (Step 560). The received television broadcast signal is input to the baseband processing unit 166 via the switching unit 162 and the RF unit 164, is subjected to signal processing to become a video signal, and is displayed via the switching circuit 82 and the personal computer function unit 83. 86.

  Note that a wireless network may be included in the LAN line. Further, the personal computer function unit 83 may perform processing such as changing the size of a display image and storing a video signal.

  On the other hand, the baseband processing unit 166 processes the received signal and outputs RSSI to the received signal monitoring unit 80. The reception signal monitoring unit 80 compares the RSSI with the RSSI level necessary for displaying a video with a good television broadcast reception signal received via the wireless LAN module 161. Also in the second embodiment, the RSSI level necessary for good video display is stored in advance in the storage unit 85 of the personal computer function unit 83.

  Next, when the television broadcast reception is terminated in the middle of the television program displayed on the display unit 86 or at the end of the television program (YES in step 575), to the television broadcast reception unit 70 and the wireless LAN module 161. In step 505, it is determined whether or not to view the television broadcast again. If not (NO in step 505), the process returns to step 505 to prepare for the television broadcast viewing.

  In addition, while the television broadcast signal received by the television broadcast receiver 70 is being received, the received signal monitor 80 receives the BER signal from the baseband processor 74 and continues to monitor the reception status. Therefore, for example, when the information processing apparatus 200 is brought indoors and the reception state in the television broadcast receiving unit 70 deteriorates and the BER signal falls to a level at which a good video cannot be displayed, the reception status from the received signal monitoring unit 80 is changed. In response to the reception status signal from the personal computer function unit 83, the power supply to the MPEG decoding unit 76 of the television broadcast receiving unit 70 is stopped and the connection of the switching circuit 82 is set to B-C. Switch between connections. At the same time, a power control signal is sent from the personal computer function unit 83 to the wireless LAN module 161, and an access signal and a channel selection signal for an access point installed indoors in the baseband processing unit 166 of the wireless LAN module 161 from the personal computer function unit 83. send. In the wireless LAN module 161, the switching unit 162 is switched to the transmission side, and the access signal and the channel selection signal are transmitted via the antenna 160. After the transmission, the switching unit 162 is switched to the reception side and enters a reception standby state.

  The BER signal is sent from the baseband processing unit 74 of the television broadcast receiving unit 70 to the received signal monitoring unit 80 while the television broadcast is received and displayed via the wireless LAN module 161. When the BER signal becomes higher than a level at which a good video can be displayed, the television broadcast reception by the wireless LAN module 161 is stopped, and the television broadcast reception via the television broadcast receiving unit 70 is switched.

  In this manner, the information processing apparatus 200 switches between a method of directly receiving a television broadcast by the television broadcast receiver 70 and a method of indirectly receiving a television broadcast via the wireless LAN module 161 according to the state of the received signal. Therefore, it is possible to view a television broadcast both outdoors and indoors.

  In the second embodiment, the wireless LAN module is used as the means for indirectly receiving the television broadcast, but other wireless communication methods such as Bluetooth may be used.

  Next, a third embodiment will be described with reference to FIG. FIG. 7 shows the main part of the third embodiment applied to the first and second embodiments, and shows only the vicinity of the switching circuit 82 of the first and second embodiments.

FIG. 7A shows a configuration in which the output of the MPEG decoding unit 76 can be stored in the storage unit 600, and video can be recorded from the television broadcast receiving unit 70. With this configuration, while the reception state of the television broadcast receiver 70 is deteriorated, the television broadcast is switched to the W-CDMA transceiver 91 of the first embodiment or the wireless LAN module 161 of the second embodiment. While the display is interrupted, the video from the television broadcast receiving unit 70 is recorded in the storage unit 600 in the meantime, the DF of the switch SW1 is connected, and the recorded video is delayed and reproduced. The switch SW1 is configured to be switched to the connection between E and F at the time when the video based on the TV broadcast signal from the W-CDMA transceiver 91 or the wireless LAN module 161 can be displayed. Since it comprised in this way, the interruption | blocking of the image | video at the time of switching between a television broadcast direct receiving means and a television broadcast indirect receiving means can be decreased.

  The storage unit 600 may be configured to use the storage unit 85 in the first and second embodiments, and the control of the SW1 is controlled by a control signal from the signal processing unit 84. It is preferable to do.

  FIG. 7B shows a configuration in which a signal in a state before being decoded by the MPEG decoding unit 76 is stored in the storage unit 85 in the personal computer function unit 83. The baseband processing unit 74 performs baseband processing. The signal is stored in the storage unit 85 via the signal processing unit 84. When the TV broadcast signal stored in the storage unit 85 is reproduced, the signal is input to the MPEG decoding unit 76, subjected to the MPEG decoding process and processed into a video signal, and then the signal is passed through the AC indirect point of the switching circuit 82. The information is displayed on the display unit 86 via the processing unit 84.
