As shown in FIG. 4, the application 300 to be installed in the set-top box 20 includes a Bluetooth control part 310, a WiFi control part320 and a Bluetooth server part 330.
The Bluetooth control part 310 controls the CPU 110 of the set-top box 20 to cause the set-top box 20 to establish a wireless
transmission path of Bluetooth between the set-top box 20 and the mobile phone 10 and start communication with the mobile phone 10 through Bluetooth. The mobile phone 10 then can be used to control operations of the set-top box 20 or transmit a music file to the set-top box 20 through Blue tooth so as to play the music file from the television set 30 via the set-top box 20.
The WiFi control part 320 controls the CPU 110 of the set-top box 20 to cause the set-top box 20 to establish a wireless transmission path of WiFi between the set-top box 20 and the mobile phone 10 and start communication with the mobile phone 10 through WiFi. The mobile phone 10then can transmit video images of moving pictures taken via the built-in camera 190 to the set-top box 20 through the thus established wireless transmission path of WiFi between the set-top box 20 and the mobile phone
10 so as to reproduce the video images from the television set 30 via the set-top box 20 in a real-time manner, for example.
Also, using the thus established wireless transmission path of WiFi between the set-top box 20 and the mobile phone 10, the set-top box 20 is connected with the server 50 via the mobile phone 10, the mobile communication network 70 and the Internet 80. Thus, it is possible to update firmware installed in the set-top box 20 based on data transmitted from the server 50 through the thus established transmission path between the set-top box 20 and the server 50 via the mobile phone 10, the mobile communication network 70 and the Internet 80.
The Bluetooth server part 330 controls the CPU 110 of the set- top box 20 to cause the set-top box 20 to establish a piconet of Bluetooth with the sensors 91 , 92, ... and 97 so as to acquire sensor information therefrom. The sensor information can be received by the mobile phone 10from the set-top box 20 through Bluetooth, or can be received by the personal computer 60 via the set-top box 20, the gateway 40 and the
Internet 80, as mentioned above. In this case, the set-top box 20 can transmit the sensor information to the gateway 40 through WiFi (using the function of the WiFi control part 320) or another wireless communication scheme.
The set-top box 20 also has other functions a common set-top box has for receiving signals concerning TV content from a cable television station or the like; providing the TV content to the television set 30 after processing the provided signals. The television set 30 thus plays the TV content. These functions are implemented as a result of a program(s) (application(s)) being executed by the CPU 110 using the hardware resources shown in FIG. 2 and so forth.
The mobile phone 10 implements the various functions in a flow of a process which will now be described using FIG. 5.
In step S510 of FIG. 5, in response to a user's instruction that is input to the mobile phone 10 via the input device 150, the mobile phone 10 downloads the application 200from the server 50 through the mobile communication network 70 and the Internet 80 and installs it in the storage device 140.
Then, in step S520, the application 200 is executed by the CPU 110 and the Bluetooth control part 220 cooperates with the Bluetooth control part 310 of the application 300 in the set-top box 20 so as to establish a wireless transmission path of Bluetooth between the mobile phone 10 and the set-top box 20.
Note that in step S520, the Bluetooth control part 220 of the mobile phone 10 requests the user of the mobile phone 10 to input authentication information such as a login password, a user ID and/or the like for establishing the wireless transmission path of Bluetooth between the mobile phone 10 and the set-top box 20. An unauthorized mobile phone user does not have such authentication information and thus, cannot establish such a wireless transmission path with the set-top box 20. As a result, the user of the mobile phone 10 can ensure security concerning operations of the set-top box 20.
In step S530 of FIG. 5, the user can control operations of the set-top box 20 through the thus established wireless transmission path of Blue tooth. In this case, the user can use a GUI of the mobile phone 10 as a controller to control the set-top box 20.
Note that a signal for controlling operations of the set-top box 20 through the thus established wireless transmission path of Bluetooth has priority over a signal for controlling operations of the set-top box 20 by a normal controller such as a wireless communication terminal conforming to IrDa. Therefore, it is not possible to use the normal controller of the set-top box 20 after the wireless transmission path of Bluetooth is established between the mobile phone 10 and the set-top box 20.
The user of the mobile phone 10 can also play a music file stored in the mobile phone 10 from the television set 30 in step S540.
That is, in step S540, the Bluetooth control part 220 reads out a music file (i.e., a stereo sound file or the like) previously stored in the storage device 140 of the mobile phone 10 and transmits the music file to the set-top box 20 through the wireless transmission path of Bluetooth established in step S520. Then, it is possible to play the music file from the television set 30 via the set-top box 20. Thus, in this case, the set-top box 20 can be used as a high quality music player.
The user of the mobile phone 10 can also reproduce video images taken by the built-in camera 190 from the television set 30 via the set-top box 20 in a real-time manner, for example.
In this regard, since wireless communication of the Bluetooth scheme doesn't necessarily provide a sufficient transmission rate for, for example, transmitting video images to reproduce them in a real-time manner at a destination apparatus. Therefore, according to the present embodiment, a WiFi scheme is available in addition to the Bluetooth scheme, also a common standard wireless communication scheme of a smart phone, which is more suitable for such a purpose.
Actually, in step S550 of FIG. 5, in response to a user's instruction that is input to the mobile phone 10 via the input device 150, the WiFi control part 230 of the mobile phone 10 requests a WiFi key from the WiFi control part 320 of the set-top box 20 for encrypting information (video images or the like) to be transmitted to the set-top box 20 through WiFi for ensuring security.
Then, in step S560, using the WiFi key acquired in step S550, the WiFi control part 230 of the mobile phone 10 starts communication with the set-top box 20 through WiFi in cooperation with the WiFi control part 320 of the set-top box 20. Thus, a wireless transmission path of WiFi is established between the mobile phone 10 and the set-top box 20 while the wireless transmission path of Bluetooth established in step S520 is disconnected.
Via the thus established wireless transmission path of WiFi, in step S570,it is possible to reproduce video images of moving pictures taken by the camera 190 of the mobile phone 10 from the television set 30 in a real-time manner via the set-top box 20. Thus, according to the present embodiment, it is possible to watch moving pictures taken by the mobile phone 10 from a large screen TV without need of a USB or a HDMI cable.
By using the thus established wireless transmission path of WiFi, it is also possible to update firmware installed in the set-top box 20.
That is, the set-top box 20 is connected with the server 50 via the mobile phone 10 through WiFi, the mobile communication network 70 and the Internet 80. Therefore, it is possible to update firmware installed in the set-top box 20 based on data transmitted from the server 50 through the thus established transmission path between the set-top box 20 and the server 50.
Further, it is also possible to use the set-top box 20 as a Bluetooth server by connecting the sensors 91 , 92, ... and 97 such as a temperature sensor, a safety sensor and so forth with the set-top box 20 via a piconet established through Bluetooth. Then, the set-top box 20 collects the sensor information of the sensors 91 , 92, ... and 97 via the piconet. Note that the sensors 91 , 92, ... and 97 also have respective functions as Blue tooth communication terminals.
In this case, the thus collected sensor information can be received by the mobile phone 10 from the set-top box 20 through the above- mentioned wireless transmission path of Bluetooth established in step S520, or can be received by the personal computer 60 via the set-top box 20, the gateway 40 and the Internet 80 without using the mobile phone 10. Thus, a user can monitor the sensor information from the mobile phone 10 or from the personal computer 60.
