圖2所示為根據本發明一實施例所繪示之無線顯示系統之系統方塊圖，其中相較於圖1所示實施例，圖2提供了一種較為詳細的實施方式。請參照圖2，其中不同於圖1的實施方式在於，電子裝置110更包括一耦接第一無線網路模組113及第一無線傳收模組111的處理單元112、遙控器更包括一耦接第二無線傳收模組121及遙控模組123的控制單元122，以及電子裝置130更包括一第二處理單元132及顯示單元134。FIG. 2 is a block diagram of a system of a wireless display system according to an embodiment of the invention, wherein FIG. 2 provides a more detailed embodiment than the embodiment shown in FIG. Please refer to FIG. 2 , wherein the electronic device 110 further includes a processing unit 112 coupled to the first wireless network module 113 and the first wireless transceiver module 111 , and the remote controller further includes a The control unit 122 of the second wireless transceiver module 121 and the remote control module 123, and the electronic device 130 further includes a second processing unit 132 and a display unit 134.
在本實施例中，第一無線傳收模組111及第二無線傳收模組121以NFC技術中的讀卡器模式(Reader/Writer mode)運作，亦即第一無線傳收模組111為一NFC讀取器(Reader)而第二無線傳收模組121為一NFC射頻標籤(Tag)。當電子裝置110接近遙控器120時(或是遙控器120接近手持裝置110)，第一無線傳收模組111傳送一讀取信號RS至第二無線傳收模組121，第二無線傳收模組121，也就是一NFC射頻標籤接收到讀取信號RS之能量並被能量激發，並將儲存於NFC射頻標籤中之資訊，也就是預先儲存於第二無線傳收模組121的連線資訊NI，透過前述之能量傳送至第一無線傳收模組111。In this embodiment, the first wireless transceiver module 111 and the second wireless transceiver module 121 operate in a reader mode (Reader/Writer mode) in the NFC technology, that is, the first wireless transceiver module 111. The second wireless transceiver module 121 is an NFC radio frequency tag (Tag). When the electronic device 110 approaches the remote controller 120 (or the remote controller 120 approaches the handheld device 110), the first wireless transceiver module 111 transmits a read signal RS to the second wireless transceiver module 121, and the second wireless transmission and reception The module 121, that is, an NFC radio frequency tag receives the energy of the read signal RS and is excited by the energy, and stores the information stored in the NFC radio frequency tag, that is, the connection pre-stored in the second wireless transmission module 121. The information NI is transmitted to the first wireless transmission module 111 through the aforementioned energy.
值得注意的是，在本實施例中，當第二無線傳收模組 121，也就是NFC射頻標籤被讀取信號RS激發時，除了回傳連線資訊至電子裝置110外，亦發出一喚醒(wake up)要求REQ1至遙控器120的控制單元122以喚醒電子顯示裝置130。所述之喚醒要求REQ1可以是喚醒電子顯示裝置130的要求、亦可是喚醒電子顯示裝置130致能(enable)無線網路模組133之能力等，依照實際實施情況設定喚醒要求REQ1之要求內容。It should be noted that in this embodiment, when the second wireless transceiver module 121, that is, when the NFC radio frequency tag is excited by the read signal RS, in addition to returning the connection information to the electronic device 110, a control unit 122 that wakes up the request REQ1 to the remote controller 120 is also issued to wake up the electronic display device. 130. The wake-up request REQ1 may be a request to wake up the electronic display device 130, or the ability to wake up the electronic display device 130 to enable the wireless network module 133, and set the required content of the wake-up request REQ1 according to the actual implementation.
控制單元122接著將喚醒要求REQ1根據遙控模組123的傳送介面編碼喚醒要求REQ1並傳送至遙控模組123。遙控模組123接收到編碼後喚醒要求REQ1’便將編碼後喚醒要求REQ1’傳送至電子顯示裝置130。其中，遙控模組123的傳送介面使用一般習知技術之紅外線或射頻傳輸介面等進行傳輸，本發明並不限定此傳送介面的設置方式。電子顯示裝置130藉由遙控接收模組132接收編碼後喚醒要求REQ1’，並傳送至第二處理單元132以進一步的解碼編碼後喚醒要求REQ1’並分析要求內容以及完成要求，例如喚醒電子顯示裝置130、致能無線網路模組133等。The control unit 122 then transmits the wake-up request REQ1 according to the transmission interface code of the remote control module 123 to the remote control module 123. The remote control module 123 transmits the encoded wakeup request REQ1' to the electronic display device 130 upon receiving the encoded wakeup request REQ1'. The transmission interface of the remote control module 123 is transmitted by using an infrared or radio frequency transmission interface of a conventional technique, and the present invention does not limit the arrangement of the transmission interface. The electronic display device 130 receives the encoded wake-up request REQ1 ′ by the remote control receiving module 132 and transmits it to the second processing unit 132 to further decode the encoded wake-up request REQ1 ′ and analyze the required content and complete the request, such as waking up the electronic display device. 130. Enable the wireless network module 133 and the like.
在另一實施例中，儲存於第二無線傳收模組121中的連線資訊NI可能不具備足夠的資訊，例如當第二無線通信協定為藍牙時，為了傳輸安全考量，於每次與新的電子裝置(例如電子裝置110)配對時，皆須產生一組新的pin code。在這樣的情況下，第二無線傳收模組121會在被讀取信號RS激發後，除了發送喚醒要求REQ1至控制單元 122外，更發送一資料要求至控制單元122，以相同於喚醒要求REQ1的處理流程傳送至電子顯示裝置130。電子顯示裝置130的第二處理單元132在接收到資料要求後，則會針對資料要求的內容，透過遙控接收模組132及遙控模組123的傳送介面回傳一回覆資料至遙控器120，例如對應於前述之pin code等資訊。遙控器120在獲得由電子顯示裝置130所回傳的回覆資料即將其中所包括的連線資訊等資訊一併回傳至電子裝置110。In another embodiment, the connection information NI stored in the second wireless transceiver module 121 may not have sufficient information, for example, when the second wireless communication protocol is Bluetooth, in order to transmit security considerations, each time When a new electronic device (such as electronic device 110) is paired, a new set of pin codes must be generated. In this case, the second wireless transceiver module 121 will send the wake-up request REQ1 to the control unit after being excited by the read signal RS. In addition to 122, a data request is sent to the control unit 122 to be transmitted to the electronic display device 130 in the same processing flow as the wake-up request REQ1. After receiving the data request, the second processing unit 132 of the electronic display device 130 returns a reply data to the remote controller 120 through the transmission interface of the remote control receiving module 132 and the remote control module 123 for the content of the data request, for example, Corresponding to the aforementioned pin code and other information. The remote controller 120 returns the information such as the connection information included in the reply data returned by the electronic display device 130 to the electronic device 110.
請繼續參照圖2，電子裝置110的第一無線傳收模組111在接收到連線資訊NI後，從第一無線傳收模組111傳送至第一處理單元112。第一處理單元112將連線資訊NI傳送至第一無線網路模組113。然後在第一無線網路模組113接收到連線資訊NI後，便根據連線資訊NI與電子顯示裝置130的第二無線網路模組133進行網路連線。當連線完成後，第一處理單元112則將從視訊原始資料VO壓縮編碼產生的視訊資料VS傳送至第一無線網路模組113。第一無線網路模組113在接收視訊資料VS之後，透過該網路連線傳送視訊資料VS至電子顯示裝置130。Referring to FIG. 2 , the first wireless transceiver module 111 of the electronic device 110 transmits the connection information NI from the first wireless transceiver module 111 to the first processing unit 112 .

Then, after the first wireless network module 113 receives the connection information NI, the network connection is performed according to the connection information NI and the second wireless network module 133 of the electronic display device 130. After the connection is completed, the first processing unit 112 transmits the video data VS generated by compressing and encoding the video original data VO to the first wireless network module 113. After receiving the video data VS, the first wireless network module 113 transmits the video data VS to the electronic display device 130 through the network connection.
電子顯示裝置130接由第二無線網路模組133接收視訊資料VS後，將視訊資料VS傳送至第二處理單元132解碼解壓縮得到視訊原始資料VO。第二處理單元132接著將視訊原始資料VO傳送至顯示單元134以顯示視訊的內容。After receiving the video data VS by the second wireless network module 133, the electronic display device 130 transmits the video data VS to the second processing unit 132 to decode and decompress the video original data VO.
