The display controller 104 converts the stream data stored in the VRAM from the YUV data format to the RGB data format, and displays the RGB data on the LCD 121. As described above, when the antenna 401 is connected to the antenna terminal 18, the internal TV tuner 1 1 1 is preferentially used and the broadcast data received by the internal TV tuner 1 1 1 is reproduced. On the other hand, when the antenna 410 is not connected to the antenna terminal 18, it responds to a logic "1" selection signal SEL indicating selection of an external TV tuner (set-top box 20), and the selector 1 15 is connected to the second stream. Controller U4 to busbar 1. The command from the TV regeneration control program indicating the reception of the broadcast data is transmitted to the network controller 1 1 3 through the selector 15 and the second stream controller 1 1 4 . The network controller 1 1 3 starts wireless communication with the set-top box 20. The network controller 1 1 3 sends a command to the set-top box 2 0 via the network 100. As shown by the dotted line in Fig. 4, the broadcast data received by the TV tuner 201 of the set-top box 20 is transmitted to the computer 10 through the network 1 无线 无线 wirelessly. The broadcast data is received by the network controller 113 and converted to digital YUV data format stream data by the stream controller 14.

As described above, when the antenna 401 is not connected to the antenna terminal 18, the processing for receiving the broadcast data transmitted from the set-top box 20 by the wireless signal is automatically performed, and the computer 1 〇 is regenerated by the set-top box 20. The broadcast resource can be used to reproduce the broadcast material currently being broadcast, such as a TV program, in the state where the antenna 401 is not connected to the main body 11 of the computer 1 。. In particular, since such a configuration is designed to automatically select one of the internal tuner 1 1 1 and the set-top box 20 in accordance with the connection/disconnection of the antenna 4 Q 1 , the user does not need to care about using the internal tuner 11 1 and the machine. Upper box 2 0 which one. Moreover, since the communication between the computer 10 and the set-top box 2 is performed by the wireless signal, the user can see/hear the broadcast material that is currently being broadcast, such as the TV program, regardless of where the computer 10 is used at home. In the second example, one of the internal tuner 1 1 1 and the set-top box 20 is automatically selected under the control of the TV reproduction control program. In particular, in the second example, the selector 1 15 and the selection signal generator 1 17 shown in Fig. 4 are not provided. The first stream controller 1 1 2 and the second stream controller 1 1 4 are directly connected to the bus bar 1. A register 501 accessible by the CPU 101 is disposed on the bus bar 1. The register 5 0 1 stores data indicating the detection result of the detector 1 16 . Among other points of view, the second example is the same as the configuration shown in FIG. -13- (11) 1272505 The TV reproduction control operation of the TV reproduction control program will now be described with reference to the flowchart of Fig. 6. If the TV reproduction control program is started (step S1 01), then 1 0 1 performs the following processing under the control of the TV reproduction control program. Initially, the CPU 101 reads the register 501 and determines whether the antenna is connected to the antenna terminal 18 (step S102). If the antenna 40 1 is to the antenna terminal 18, the CPU 101 sends a command to receive the broadcast material to the internal TV 1 1 1 through the first stream controller 1 1 2 S 1 0 3 ). Then, the CPU 101 receives the broadcast data received by the TV tuner through the first stream controller 1 1 2 (step s 1 0 4 ), and causes the display controller to reproduce the received broadcast data (step S 1 0 5 ) . On the other hand, if the antenna 401 is not connected to the antenna terminal 1 8 CPU 1 0 1 , the network controller 1 is controlled via the second stream controller 1 1 4 to start wireless communication with the set-top box 20. The CPU 101 transmits a command to receive the broadcast material to the set-top box 20 (; S 106 ) via the network. Then, the CPU 101 receives the broadcast transmitted from the set-top box 2 Q by the wireless signal through the network controller 1 13 and the second controller 1 14 (step S107), and reproduces the broadcast data using the display controller 104 (step S 1 0 5 ). FIG. 7 illustrates a third example of the system configuration of the computer 10. In the third example, when the antenna 401 is connected to the antenna terminal 18, one of the inner aligner 11 1 and the set-top box 20 is selected based on the transmission rate of the broadcast data transmitted from the set-top box 20. In order to achieve this planning, the example includes a selection signal generator 601 configured to perform a CPU 40 1 connection (the internals of the step-and-tuner are used, then the 13th, 100th, and the second is based on the data stream. -14- (12) 1272505 値 generation selection SEL of the transmission rate of the broadcast data from the set-top box 20. As shown in Fig. 7, the selection signal generator 601 includes the register 6 transmission rate detecting unit 6 1 2. And the comparator 6 1 3. The register of the storage rate is stored in the register 6 1 1 . The transmission rate detecting unit 6 1 2 calculates the amount of data per unit time output from the second controller 1 1 4, The transmission rate (bit transmission rate) of the broadcast data sent by the upper box 20 is detected. The device 613 is a circuit for generating the selection signal SEL. If the detector Π 6 detects that the antenna 4 0 1 is not connected to the antenna terminal Then, the comparator 6 13 generates an indication to select an external TV tuner (the 2-bit selection signal SEL (0, 1) of the set-top box. On the other hand, if the detector 1 16 detects that the antenna 40 1 is connected to the terminal 18, then the comparator 6 1 3 generates an indication to select the internal TV tuner and the external TV tuner (machine The box 2 0 ) the two bits of the two select SEL ( 1,1 ). Thus, the command indicating the reception of the broadcast material is sent not only to the internal TV tuner 1 1 1 but also to the set-top box 20. 6 1 3 compares the transmission rate of the broadcast data from the machine 20 detected by the transmission rate detecting unit 6 1 2 with the reference 储存 stored in the register 6 1 1 to determine the detection. Whether the transmission rate 到 is higher than the reference 値. If the detected transmission rate 値 is equal to or higher than the reference 値, the 2 selection signal indicating the selection of the external TV tuner (set-top box 2 0) is generated than 6 1 3 SEL (0,1). If the detected transmission rate 値 is lower than 値, the comparator 6-1 generates an indication to select the internal TV tuner 1 i signal | 1 b first stream stream self-machine comparison 18, 20 ) antenna After the signal is sent, the upper box transmission rate is 2 -15- (13) (13) 127255 bit selection signal SEL ( 1, 〇) ° when the signal is transmitted. Even when the antenna 4 0 1 is connected to the antenna terminal 1 8 'If the antenna 4 0 1 is an indoor antenna', there may be an image of the broadcast data transmitted from the set-top box 20 through the wired or wireless network 100. The quality is higher than the image quality of the broadcast data from the internal TV tuner 1 1 1. In addition, the transmission rate of the broadcast data from the set-top box 20 is increased due to, for example, the traffic of the network 10 or the wireless communication environment is poor. And the reduction. The reduction in transmission rate will result in poor image quality. In the computer 1, the internal τ V tuner 1 1 1 and the set-top box 20 are selected according to the transmission rate of the broadcast data from the set-top box 20, and the broadcast material having higher quality can be reproduced. . If the functions of the transmission rate detecting unit 6 1 2 and the comparator 613 are set in the TV regeneration control program, the second configuration shown in FIG. 5 can also be based on the on-board control under the control of the TV regeneration control program. The transmission rate of the broadcast data of the box 20 is performed to select one of the operations of the internal tuner 1 1 1 and the set-top box 2 0 . As described above, according to the computer of the embodiment, the broadcast material currently being broadcast, such as a TV program, can be reproduced even in a state where the antenna is not connected to the main body of the computer.
