The set-top box 20 includes a TV tuner 201 and a network controller 202. The tuner 201 is an external receiving device that receives broadcasting materials such as TV program materials and the like. The TV tuner 2 0 1 receives broadcast data of the channel number specified by the command transmitted from the computer 1 1 via the network 1 0. The tuner 2 0 1 is connected to the set-top box 2 through the antenna cable. 0 TV antenna 4 0 2. For example, an outdoor antenna can be used as the τ V antenna 402. The broadcast of the specific channel number received by the internal TV tuner 201 is sent to the network controller 202. The network controller 202 is a communication device that performs communication with external devices through a wire or wireless network 100. The network controller 1 1 3 in the computer 10-generally, the network controller 2 2 includes a wired network device or a wireless network device. The network controller 2 transmits the broadcast data received by the TV tuner 20 1 to the computer 1 through the network 100. In the following description, the network controller in the computer 10 is assumed! Each of them and the network controller 202 in the set-top box 20 are implemented by wireless network settings, and the communication between the computer 10 and the set-top box 20 is performed with no signal. In the computer 10, when the antenna 40 1 is connected to the antenna terminal 18, the logic of not selecting the internal VT V tuner 1 1 1 should be, 〇, select the letter SEL, selector! ; [5 connect the first stream controller u 2 to the bus] Instruction to receive broadcast data from the TV regeneration control program through -11-200521721 (9) Selector 1 5 and the first stream controller 1 1 2 It is sent to the internal τ V tuner 1 1 1. The broadcast data received by the internal TV tuner 11 1 is converted by the first stream controller 1 1 2 into digital YUV data format stream data, and as shown by the dotted line in FIG. 4, it is transmitted from the first through the selector 1 1 5 The stream controller 1 1 2 outputs the stream data to the bus 1. The stream data output to the bus 1 is stored in the VRAM 105 through the I / O controller 106, the host controller 102, and the display controller 104. The display controller 104 converts the streaming 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 40 1 is not connected to the antenna terminal 18, in response to a logic "1" selection signal SEL indicating the selection of an external TV tuner (box 20), the selector 1 1 5 is connected to the second stream Controller 1 1 4 to bus 1. A command from the TV reproduction control program instructing reception of broadcast data is sent 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 20 via a wireless signal through the network 1 0 0. As shown by the dotted line in FIG. 4, the broadcast data received by the TV tuner 20 1 of the set-top box 20 is transmitted to the computer 10 through a wireless signal via the network 100. The broadcast data is received by the network controller 1 1 3 and converted into digital YUV data format stream data by the stream controller 1 1 4. The stream data is output to the bus 1 through the selector 1 1 5. The stream data output to the bus 1 -12- 200521721 (10) The data is stored in the VRAM 105 through the I / O controller 106, the host controller 102, and the display controller 104. The display controller 104 converts the streaming 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 not connected to the antenna terminal 8, the processing for receiving broadcast data sent from the set-top box 20 by wireless signals is automatically performed, and the computer 10 reproduces the broadcast received by the set-top box 20 data. In a state where the antenna 4 01 is not connected to the main body 11 of the computer 10, the set-top box 20 can be used to reproduce broadcasting materials such as TV programs currently being broadcast. In particular, since this configuration is designed to automatically select one of the internal tuner 111 and the set-top box 20 according to the connection / disconnection of the antenna 401, the user need not worry about using the internal tuner 11 1 and the set-top box 20 Which one. Furthermore, since the communication between the computer 10 and the set-top box 20 is performed by a wireless signal, the user can see / hear broadcast materials such as TV programs, etc., wherever 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, the selector 1 1 5 and the selection signal generator 1 1 7 shown in Fig. 4 are not provided in the second example. The first stream controller 丨 2 and the second stream controller 1 1 4 are directly connected to the bus 1. A register 5 0 1 which can be accessed by C P U 1 0 1 is set on the bus 1. The register 5 0 1 stores data indicating the detection result of the detector 1 1 6. In other points of view, the second example is the same as the configuration shown in Fig. 4. -13- 200521721 (11) The TV reproduction control operation performed by 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 S 1 0 1), the 101 performs the following processing under the control of the TV reproduction control program. Initially, the CPU 101 reads the register 501 and decides whether or not the antenna is connected to the antenna terminal 18 (step S 102). If the antenna 40 1 to the antenna terminal 18, the CPU 110 sends a command instructing reception of broadcast data to the internal TV tuner 111 through the first stream controller 1 12 (S 1 0 3). Then, the CPU 101 receives the broadcast data received by the TV tuner through the first stream controller 112 (step s 1 04), and causes the display controller to reproduce the received broadcast data (step S 1 05). On the other hand, If the antenna 401 is not connected to the antenna terminal 1 CPU 1 0 1 controls the network controller 1 through the second stream controller 1 1 4 to start wireless communication with the set-top box 20. C P U 1 0 1 transmits a command for receiving broadcast data via the network to the set-top box 20 (S 106). Then, the CPU 101 receives the broadcast transmitted from the set-top box 20 as a wireless signal through the network controller 113 and the second controller 114, and reproduces the received broadcast data using the display controller 10 ( 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 internal device 1 1 1 and the set-top box 2 0 is selected according to the transmission rate of the broadcast data transmitted from the set-top box 20. In order to achieve this plan, the example includes a selection signal generator 601, which is configured to perform a CPU 40 1 connection: _ 14- 200521721 (12) SEL generation of transmission rate of broadcast data from set-top box 2 0 SEL ° As shown in Fig. 7, the selection signal generator 60 1 includes a register transmission rate detection unit 6 1 2, And the comparator 6 1 3. The temporary register 6 1 1 stores the reference of the transmission rate. The transmission rate detection unit 6 1 2 calculates the amount of data per unit time output from the controller 1 1 4 to detect the box. 20 The transmission rate (bit rate) of the broadcast data transmitted. The device 613 is a circuit that generates a selection signal SEL. If the detector 1 1 6 detects that the antenna 40 1 is not connected to the antenna terminal, the comparator 6 1 3 Generates an instruction to select an external TV tuner (the 2-bit selection signal SEL (0,1) on the aircraft. On the other hand, if the detector 1 1 6 detects the antenna 40 1 and connects the terminal 1 8, the comparator 6 1 3 Generates instructions to select 2 bits of both internal TV tuner and external TV tuner (set-top box 2 0) Select SEL (1, 1). In this way, the command for receiving broadcast data is not sent to the internal TV tuner 1 1 1 but also sent to the set-top box 2 0. The comparator 6 1 3 sends the transmission rate detection unit 6 1 The transmission rate 値 of the broadcast data detected from 2 is compared with the reference 储存 stored in the temporary register 6 1 1 to determine whether the detected transmission rate 高于 is higher than the reference 若. The measured transmission rate 値 is equal to or higher than the reference 値, 6 1 3 generates a selection signal SEL (〇, 1) indicating the selection of an external TV tuner (set-top box 20). If the detected transmission rate 値 is low 値Then, the comparator 6 1 3 generates an instruction to select the internal TV tuner 1: the selection signal 6 11. The second stream is stored in advance. The comparison terminal 1 8, t 20) to the antenna 1 1 1 is only selected after the selection signal is sent. The set-top box transmission rate is equal to or equal to 2 bits of the comparator 1 2 of the reference 1 -15- 200521721 (13) bit selection signal SEL (1, 0). Even when the antenna 40 1 is connected to the antenna terminal 18, if The antenna 401 is an indoor antenna, and there may be broadcast data transmitted from the set-top box 20 through a wired or wireless network 10000 There is a case where the image quality of the broadcast data is higher than that of the broadcast data from the internal TV tuner 111. In addition, the transmission rate of the broadcast data from the set-top box 20 may be increased due to, for example, the traffic of the network 100 or the wireless communication environment And the reduction. The reduction of the transmission rate will result in poor image quality. In the computer 10, one of the internal TV tuner 1 1 1 and the set-top box 20 is selected according to the transmission rate of the broadcast data from the set-top box 20, and the broadcast material with higher quality can be reproduced. If the functions of the transmission rate detection unit 6 1 2 and the comparator 6 1 3 are provided in the TV reproduction control program, the second configuration shown in FIG. 5 can also be controlled by the slave device under the control of the TV reproduction control program. The transmission rate of broadcast data of the upper box 20 is performed by selecting one of the internal tuner 1 1 1 and the set-top box 2 0. As described above, according to the computer of the embodiment, even in a state where the antenna is not connected to the main body of the computer, it is possible to reproduce broadcasting materials such as TV programs currently being broadcast. Those skilled in the art will easily find other advantages and corrections.
