CLAIM OF PRIORITY 
     This application claims priority to Taiwanese Patent Application No. 099124852 filed on Jul. 28, 2010. 
     FIELD OF THE INVENTION 
     The present invention relates to a wireless communication system, and more particularly to a wireless communication system by using a wireless communication protocol with a data flow of a multimedia data packet and a control data packet. 
     BACKGROUND OF THE INVENTION 
     Recently, the general trends in designing portable communication devices are toward small size, light weightiness and fashionable appearance. In addition, diversified functions are imparted to the portable communication devices. For example, the extended functions of a smart phone include an image-capturing function (e.g. likes a digital camera), a wireless communication function (e.g. likes a WiFi and Bluetooth device), an audio and video signal output function (e.g. likes a IPTV box, Apple TV or Google TV box), and a positioning function (e.g. likes a global positioning system). For implementing the audio and video signal output function, the Composite audio and video output interface (AV-out) or HDMI interface of the smart phone is connected with an external display device (e.g. a TV set or a LCD display) through a signal transmission line. As a consequence, the audio and video multimedia data stored in the smart phone may be viewed through a larger screen, or the displaying image of the smart phone may be simultaneously displayed on dual screens. The use of the signal transmission line to transmit the audio and video multimedia data, however, is not user-friendly because of the length limitation of the signal transmission line. For solving this drawback, the audio and video multimedia data may be transmitted according to a wireless transmission technology. 
     According to progress of Cloud Computing Technology, low cost internet access device and wireless display devices such as wireless LCD, wireless projector, wireless head mounted display and smart phone are more user-friendly to compare with wired display devices to be used in this application. According to more popular of IPTV box, Apple TV and Google TV box, wireless display devices such as wireless LCD, wireless projector, wireless head mounted display and smart phone are more user-friendly to compare with wired display devices to be used in this application. 
     E-book and robot with input and output function are more popular but the functions are constrained by internal CPU. There is one method without increasing the performance of internal CPU as Cloud Computing Technology to distribute some functions to other CPU such as CPU of personal computer by using low cost wireless technology communication. 
     Generally, the method for transmitting the audio and video multimedia data according to the wireless transmission technology is implemented by an IEEE standard digital protocol wireless network system (e.g. WiFi, WLAN IEEE802.1x, Bluetooth IEEE802.15.1, UWB IEEE802.15.3), a non-IEEE standard digital protocol wireless network system (ISM band wireless devices, WHDI, WIDI) or an analog wireless network system (ISM band wireless devices). Generally, the method for transmitting the control data according to the wireless transmission technology is implemented by an IEEE standard digital protocol wireless network system (e.g. Bluetooth IEEE802.15.1, Zigbee IEEE802.15.4, WiFi WLAN IEEE802.1x), a non-IEEE standard digital protocol wireless network system (ISM band wireless devices) or an analog wireless network system (ISM band wireless devices). Since the IEEE standard digital protocol wireless network system uses a complex synergistic computation to process the audio and video multimedia data, the method of producing the IEEE standard digital protocol wireless network system is time-consuming and costly. Since the transmission of the audio and video multimedia data is readily interfered by the external noise, the data transmission quality of the analog wireless network system is non-security, deteriorated, and even an erroneous transmission problem may occur. On the other hand, for the non-IEEE standard digital protocol wireless network system, the complex synergistic computation is not necessary. In addition, the non-IEEE standard digital protocol wireless network system is more cost-effective and easily designed when compared with the IEEE standard digital protocol wireless network system and has better transmission quality when compared with the analog wireless network system. Consequently, the non-IEEE standard digital protocol wireless technology is gradually adopted in many products but the most popular system is still IEEE standard digital protocol wireless network system. 
     As known, the external display device for receiving audio and video multimedia data fails to be directly and remotely controlled by the smart phone. In addition, the common infrared remote control devices and Zigbee remote control devices still fail to be directly and remotely controlled by the smart phone. For controlling the external display device or the infrared remote control devices or the Zigbee remote control devices by the smart phone, the smart phone may be equipped with some additional components such as an infrared remote control chip, a Zigbee transceiver chip and/or a Zigbee antenna. Through these components, an infrared control signal and an IEEE standard Zigbee control signal are generated to remote control TV sets, the infrared remote control devices or the Zigbee remote control devices. Since the additional components occupy much space of the smart phone, the overall volume and thickness of the smart phone fail to be further reduced. In addition, many components mean that the power consumption and the circuitry complexity of the smart phone are increased. 
     Recently, a tablet personal computer with a touch control function (e.g. a touchpad PC), a LCD display with a touch control function, a projector, or a head mounted display becomes more popular. By touching the screen or inputting an instruction, the tablet personal computer, the wireless LCD display, the wireless projector, or the wireless head mounted display may execute a corresponding function according to a touch or data input control technology. However, the tablet personal computer and the wireless display devices, which have a touch or data input control function, still fail to remotely control smart phone which can provide multimedia data of audio and video out function. In other words, the applications of the smart phone are restricted. 
     The wireless display devices can not send HIDs signal to internet access device, IPTV box, Apple TV or Google TV box therefore the system functions are constrained. E-book and robot with input and output function can not send HIDs signal to remote control CPU, therefore the system functions are constrained.

It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed. 
       FIG. 1A  is a schematic functional block diagram illustrating a wireless communication system according to an embodiment of the present invention.

FIG. 1C  is a schematic diagram illustrating the architecture of the wireless communication system such as non-IEEE standard digital protocol wireless system, IEEE standard digital protocol wireless network system or analog wireless network system as shown in  FIGS. 1A and 1B .  FIG. 2  is a schematic diagram illustrating a data flow processed in the wireless communication system of  FIG. 1 . Please refer to  FIGS. 1A ,  1 C and  2 . The wireless communication system  1  comprises a first wireless communication module  11  and a second wireless communication module  12 . The first wireless communication module  11  has a first wireless receiving/transmitting processing unit  111 . Preferably, the first wireless receiving/transmitting processing unit  111  is configured to receive, transmit and process the data flow  2  that complies with a non-IEEE standard communication protocol. The data flow  2  comprises a multimedia data packet  21  and a control data packet  22 . The second wireless communication module  12  comprises a second wireless receiving/transmitting processing unit  121  and a multimedia data outputting unit  122 . The second wireless receiving/transmitting processing unit  121  is configured to receive, transmit and process the data flow  2 . The multimedia data outputting unit  122  is used for outputting the multimedia data signal contained in the multimedia data packet  21 . Preferably, the data flow  2  is transmitted between the first wireless communication module  11  and the second wireless communication module  12  according to the non-IEEE standard communication protocol. The control data packet  22  of the data flow  2  comprises at least one of a first remote control data packet  221  and a second remote control data packet  222 . The first remote control data packet  221  and the multimedia data packet  21  are transmitted in the same direction. The second remote control data packet  222  and the multimedia data packet  21  are transmitted in opposite directions. The second wireless communication module  12  is remotely controlled according to the first remote control data packet  221 . The first wireless communication module  11  is remotely controlled according to the second remote control data packet  222 . In this embodiment, the multimedia data packet  21  of the data flow  2  is transmitted from the first wireless communication module  11  to the second wireless communication module  12  according to the non-IEEE standard communication protocol. In an embodiment, the multimedia data packet  21  of the data flow  2  comprises at least one audio signal  211  and at least one video signal  212 . 
     Please refer to  FIGS. 1A ,  1 C and  2  again. An example of the first wireless communication module  11  includes but is not limited to a mobile phone. For transmitting the multimedia data from the first wireless communication module  11  to the second wireless communication module  12  to be played or outputted, the multimedia data is firstly converted into the data flow  2  (e.g. in a digital format) by the first wireless receiving/transmitting processing unit  111  of the first wireless communication module  11 , and then the data flow  2  is transmitted from the first wireless communication module  11  to the second wireless communication module  12  through the antenna  112  according to the non-IEEE standard communication protocol. The data flow  2  is received by the second wireless communication module  12  through the antenna  123 , and then processed by the second wireless receiving/transmitting processing unit  121 . The multimedia data signal contained in the multimedia data packet  21  will be played or outputted by the multimedia data outputting unit  122 . In such way, the efficacy of displaying a larger image or simultaneously displaying on dual screens will be achieved. 
     Moreover, during the multimedia data is transmitted from the first wireless communication module  11  to the second wireless communication module  12  to be played or outputted, the second wireless communication module  12  may be remotely controlled. By the first wireless receiving/transmitting processing unit  111  of the first wireless communication module  11 , the multimedia data and a first remote control signal are respectively converted into the multimedia data packet  21  and the first remote control data packet  221  of the data flow  2 . The first remote control data packet  221  and the multimedia data packet  21  are transmitted in the same direction. For example, the first remote control data packet  221  and the multimedia data packet  21  are transmitted in a first direction from the first wireless communication module  11  to the second wireless communication module  12 . According to the non-IEEE standard communication protocol, the data flow  2  is transmitted to the second wireless communication module  12  through the antenna  112  of the first wireless communication module  11 . After the data flow  2  is received by the second wireless communication module  12  through the antenna  123 , the data flow  2  is analyzed and processed by the second wireless receiving/transmitting processing unit  121 . Then, the multimedia data signal contained in the multimedia data packet  21  will be played or outputted by the multimedia data outputting unit  122 . Moreover, through the second wireless receiving/transmitting processing unit  121 , the second wireless communication module  12  is remotely controlled by the first wireless communication module  11  according to the first remote control data packet  221 . 
     An example of the second wireless communication module  12  includes but is not limited to a tablet personal computer or a monitor, which has wireless communication and touch control functions. For remotely controlling the first wireless communication module  11  by the second wireless communication module  12 , a second remote control signal is firstly converted into the second remote control data packet  222  of the data flow  2  by the second wireless receiving/transmitting processing unit  121  of the second wireless communication module  12 . The second remote control data packet  222  and the multimedia data packet  21  are transmitted in opposite directions. For example, the second remote control data packet  222  is transmitted in a second direction from the second wireless communication module  12  to the first wireless communication module  11 . 
     According to the non-IEEE standard communication protocol, the data flow  2  is transmitted to the first wireless communication module  11  through the antenna  123  of the second wireless communication module  12 . After the data flow  2  is received by the first wireless communication module  11  through the antenna  112 , the data flow  2  is analyzed and processed by the first wireless receiving/transmitting processing unit  111 . Moreover, through the first wireless receiving/transmitting processing unit  111 , the first wireless communication module  11  is remotely controlled by the second wireless communication module  12  according to the second remote control data packet  222 . 
     In some embodiments, a second remote control signal is directly inputted into the second wireless communication module  12  through a human-machine interface (not shown in  FIG. 1 ), then converted into the second remote control data packet  222  of data flow  2  by the second wireless receiving/transmitting processing unit  121 , and transmitted through the antenna  123 . In some embodiment, the second remote control signal comprises at least one touch remote control signal, at least one joystick remote control signal, at least one click remote control signal, at least one mouse cursor remote control signal and/or at least one keyboard input remote control signal (HIDs signal). 
     In the wireless communication system  1 , the multimedia data packet  21  and the control data packet  22  of the data flow  2  are wirelessly transmitted according to a symmetric data transmission technology or an asymmetric data transmission technology. According to the asymmetric data transmission technology, the multimedia data packet  21  is transmitted from the first wireless communication module  11  to the second wireless communication module  12  through a higher frequency band of a transmission channel, and the second remote control data packet  222  of the control data packet  22  is transmitted from the second wireless communication module  12  to the first wireless communication module  11  through a lower frequency band of the transmission channel. As a consequence, the unidirectional transmission bandwidth of the transmission channel will be increased and the speed of transmitting the multimedia data packet  21  is enhanced. 
     In some embodiments, the first wireless communication module  11  is for example, a smart phone, an internet access device, a combination of a smart phone and a mobile battery, a personal digital assistant, a notebook computer, an IPTV box, an Apple TV, a Google TV box, a PC or a tablet personal computer.

     From the above description, the wireless communication system of the present invention comprises a first wireless communication module and a second wireless communication module. The first wireless communication module and the second wireless communication module comprises a first wireless receiving/transmitting processing unit and a second wireless receiving/transmitting processing unit, respectively. In addition, the multimedia data packet and the control data packet of the data flow are transmitted between the first wireless communication module and the second wireless communication module according to the non-IEEE standard communication protocol by using a symmetric data transmission technology or an asymmetric data transmission technology. According to the touch remote control signal, the remote control signal, the click remote control signal, the mouse cursor remote control signal and/or the keyboard input remote control signal (HIDs signal) contained in the control data packet of the data flow, the first wireless communication module is remotely controlled. In addition, according to the infrared remote control signal, the Zigbee remote control signal and/or the switcher remote control signal contained in the control data packet of the data flow, the second wireless communication module is remotely controlled. Since it is not necessary to install an additional antenna or an additional wireless chip within the first wireless communication module of the present invention, the internal space and the power consumption will be reduced. In other words, the first wireless communication module of the present invention is more cost-effective. Since the multimedia data stored in the first wireless communication module may be transmitted to the second wireless communication module, the multimedia data may be viewed through a larger screen. Moreover, by inputting a control signal through the second wireless communication module, the displaying image of the first wireless communication module may be simultaneously displayed on dual screens in order to increase the value of using the first wireless communication module. Moreover, since the multimedia data packet and the control data packet of the data flow are transmitted according to the wireless communication protocol by integrating with non-IEEE standard digital protocol wireless system, IEEE standard digital protocol wireless network system or analog wireless network system and by using the symmetric data transmission technology or the asymmetric data transmission technology, if we select non-IEEE standard digital protocol wireless system, no complex protocol is used and the loading of the processor of the second wireless communication module is not largely increased.
