近年來，由於多媒體影音技術、影像轉換技術發展得相當迅速。因此市面上不斷出現各種具有不同功能的視訊傳輸的轉換裝置及視訊播放裝置。為了增進消費者在觀賞視訊上的方便性及使用彈性，如何改善轉換裝置中的視訊傳輸機制便顯得相當重要。 In recent years, multimedia video technology and video conversion technology have developed quite rapidly. Therefore, various video transmission conversion devices and video playback devices with different functions are constantly appearing on the market. In order to enhance the convenience and flexibility of consumers in viewing video, how to improve the video transmission mechanism in the conversion device is very important.
其中，DisplayPort是影片電子標準協會(VESA)推動的數位式視訊介面標準。且DisplayPort是第一個依賴封包化資料傳輸技術的顯示介面。與過去如HDMI的標準需要在每個輸出口的差分對裡面固定傳輸時鐘訊號不同。 Among them, DisplayPort is the digital video interface standard promoted by the Video Electronics Standards Association (VESA). And DisplayPort is the first display interface that relies on packetized data transfer technology. In contrast to past standards such as HDMI, it is necessary to fix the transmission clock signal in the differential pair of each output port.
然而，如電腦的多媒體主機透過DisplayPort往往無法讀取到顯示設備的EDID訊號(Extended Display Identification Data，即擴充顯示器識別資料訊號)。其中，DisplayPort係規範於AUX CH，以1Mbit/s或720Mbit/s的高速傳輸EDID訊號。然而，顯示設備的EPROM(Erasable Programmable Read Only Memory，EPROM)往往只能提供100Kbit/s的標準傳輸速率，藉此造成顯示設備無法顯示影像；或是多媒體主機與顯示設備之間無法運作等情況。所以，造成使用上的不方便。 However, if the multimedia host of the computer is unable to read the display device's EDID signal (Extended Display Identification Data) through DisplayPort. Among them, DisplayPort is standardized on AUX CH and transmits EDID signals at high speed of 1 Mbit/s or 720 Mbit/s. However, the EROM (Erasable Programmable Read Only Memory, EPROM) of the display device can only provide a standard transmission rate of 100 Kbit/s, thereby causing the display device to be unable to display images; or the multimedia host and the display device cannot operate. Therefore, it is inconvenient to use.
本創作在於提供一種轉換裝置及其轉換系統，透過EDID模擬單元控制開關的導通或截止之設計，藉此提升影音播放及顯示的使用方便性。 The present invention provides a conversion device and a conversion system thereof, and controls the on or off design of the switch through the EDID simulation unit, thereby improving the convenience of use of the audio and video playback and display.

These terms are used to distinguish one element from another, or a signal and another. In addition, as used herein, the term "or" may include all combinations of any one or more of the associated listed items.
圖1為本創作一實施例之轉換裝置之功能方塊示意圖。請參閱圖1。一種轉換裝置1，電性連接於一多媒體主機PC及一顯示設備D1之間。轉換裝置1包括一第一轉換單元11、一第二轉換單元12及一EDID模擬單元10。 FIG. 1 is a functional block diagram of a conversion device according to an embodiment of the present invention. Please refer to Figure 1. A conversion device 1 is electrically connected between a multimedia host PC and a display device D1. The conversion device 1 includes a first conversion unit 11, a second conversion unit 12, and an EDID simulation unit 10.
在實務上，第一轉換單元11透過一DisplayPort輸入埠DP1以電性連接多媒體主機PC。第二轉換單元12透過一DisplayPort輸出埠DP2以電性連接顯示設備D1。第一轉換單元11透過最小化傳輸差分訊號通道TMDS(Transition Minimized Differential Signaling，TMDS)及顯示數據訊息通道DDC(Display Data Channel，DDC)，以電性連接第二轉換單元12。 In practice, the first conversion unit 11 is electrically connected to the multimedia host PC through a DisplayPort input port DP1. The second conversion unit 12 is electrically connected to the display device D1 through a DisplayPort output port DP2. The first conversion unit 11 is electrically connected to the second conversion unit 12 by minimizing a Transmitted Minimized Differential Signaling (TMDS) and a Display Data Channel (DDC).
詳細來說，多媒體主機PC例如為DVD播放器、藍光播放器、MP4播放器、USB播放器、電腦主機、筆記型電腦或多媒體播放器等影音播放設備。顯示設備D1例如為電視、螢幕、LCD液晶顯示器、投影機或其他顯示器。藉此多媒體主機PC所輸出的影音訊 號可透過轉換裝置1，致使顯示設備D1來顯示。本實施例不限制轉換裝置1的態樣。 In detail, the multimedia host PC is, for example, a DVD player, a Blu-ray player, an MP4 player, a USB player, a host computer, a notebook computer, or a multimedia player. The display device D1 is, for example, a television, a screen, an LCD liquid crystal display, a projector or other display. The video and audio output by the multimedia host PC The number can be transmitted through the conversion device 1 to cause the display device D1 to display. This embodiment does not limit the aspect of the conversion device 1.
一般來說，多媒體主機PC透過DisplayPort介面往往無法讀取到顯示設備D1的EDID訊號。其中，DisplayPort規範係透過AUX CH，以1Mbit/s或720Mbit/s的高速傳輸EDID訊號。然而，顯示設備D1的EPROM往往只能提供100Kbit/s的標準傳輸速率。因此，本實施例透過第一轉換單元11將DisplayPort訊號轉換為HDMI訊號，並運用HDMI規範中的顯示數據訊息通道DDC來傳輸高畫質數位內容保護金鑰(High Bandwidth Digital Content Protection，HDCP)及模擬EDID訊號。因此，多媒體主機PC與顯示設備D1之間透過轉換裝置1，致使顯示設備D1可顯示多媒體主機PC所提供的影音訊號。 In general, the multimedia host PC cannot read the EDID signal of the display device D1 through the DisplayPort interface. Among them, the DisplayPort specification transmits EDID signals at a high speed of 1 Mbit/s or 720 Mbit/s through AUX CH. However, the EPROM of the display device D1 often only provides a standard transmission rate of 100 Kbit/s. Therefore, the first conversion unit 11 converts the DisplayPort signal into an HDMI signal, and uses the display data message channel DDC in the HDMI specification to transmit a high-bandwidth digital content protection (HDCP) and Simulate the EDID signal. Therefore, the multimedia device PC and the display device D1 pass through the conversion device 1, so that the display device D1 can display the video and audio signals provided by the multimedia host PC.
其中，DisplayPort協定之小的封包可將時鐘訊號嵌入在資料流中。DisplayPort協定可用於同時傳輸音訊和影訊，或是單獨傳輸音訊和影訊的其中之一。 Among them, the small packet of the DisplayPort protocol can embed the clock signal in the data stream. The DisplayPort protocol can be used to simultaneously transmit audio and video, or to transmit audio and video separately.
接下來，第一轉換單元11例如為將DisplayPort訊號轉換為HDMI訊號的轉換器。而第二轉換單元12例如為將HDMI訊號轉換為DisplayPort訊號的轉換器。在實務上，相較於HDMI訊號，DisplayPort訊號係屬高速傳輸訊號，而HDMI訊號係屬低速傳輸訊號。 Next, the first conversion unit 11 is, for example, a converter that converts a DisplayPort signal into an HDMI signal. The second conversion unit 12 is, for example, a converter that converts an HDMI signal into a DisplayPort signal. In practice, the DisplayPort signal is a high-speed transmission signal compared to the HDMI signal, and the HDMI signal is a low-speed transmission signal.
其中，第一轉換單元11例如透過使用一個外部無源介面卡來實作，選擇所需的訊號，並將電氣訊號從低電壓差分訊號(Low-Voltage Differential Signaling，LVDS)轉換為最小化傳輸差分訊號。也就是將DisplayPort規範轉換為HDMI 1.2/1.4協定規範。反之，而第二轉換單元12係將電氣訊號從最小化傳輸差分訊號轉換為低電壓差分訊號。 The first conversion unit 11 is implemented by using an external passive interface card, for example, selecting a desired signal, and converting the electrical signal from Low-Voltage Differential Signaling (LVDS) to minimizing the transmission difference. Signal. That is, the DisplayPort specification is converted to the HDMI 1.2/1.4 protocol specification. Conversely, the second conversion unit 12 converts the electrical signal from the minimized transmission differential signal to the low voltage differential signal.
接著，EDID模擬單元10電性連接於第一轉換單元11與第二轉換單元12之間的一顯示數據訊息通道DDC。顯示數據訊息通道 DDC具有一開關16，EDID模擬單元10用以控制開關16的導通或截止。在實務上，開關16例如為一雙極性接面電晶體或一金氧半場效應電晶體。 Next, the EDID simulation unit 10 is electrically connected to a display data message channel DDC between the first conversion unit 11 and the second conversion unit 12. Display data message channel The DDC has a switch 16 for controlling the turn-on or turn-off of the switch 16. In practice, the switch 16 is, for example, a bipolar junction transistor or a gold oxide half field effect transistor.
開關16導通時，顯示數據訊息通道DDC處於第一轉換單元11與第二轉換單元12之間的訊號連通狀態；反之，開關16截止時，顯示數據訊息通道DDC處於第一轉換單元11與第二轉換單元12之間的訊號斷路狀態。本實施例不限制開關16的態樣。 When the switch 16 is turned on, the display data message channel DDC is in a signal communication state between the first conversion unit 11 and the second conversion unit 12; otherwise, when the switch 16 is turned off, the display data message channel DDC is in the first conversion unit 11 and the second The signal disconnection state between the conversion units 12. This embodiment does not limit the aspect of the switch 16.
其中，於EDID模擬單元10讀取到顯示設備D1的EDID訊號時，EDID模擬單元10控制開關16截止，EDID模擬單元10輸出一模擬EDID訊號給多媒體主機PC。其中，於EDID模擬單元10讀取到一高畫質數位內容保護金鑰時，EDID模擬單元10控制開關16導通。 When the EDID simulation unit 10 reads the EDID signal of the display device D1, the EDID simulation unit 10 controls the switch 16 to be turned off, and the EDID simulation unit 10 outputs an analog EDID signal to the multimedia host PC. Wherein, when the EDID simulation unit 10 reads a high-quality digital content protection key, the EDID simulation unit 10 controls the switch 16 to be turned on.
也就是說，顯示設備D1的EDID訊號會被EDID模擬單元10讀取，EDID訊號無法通過顯示數據訊息通道DDC，且由EDID模擬單元10產生一模擬EDID訊號給多媒體主機PC。此外，高畫質數位內容保護金鑰可通過顯示數據訊息通道DDC，致使多媒體主機PC與顯示設備D1之間進行高畫質數位內容保護金鑰技術的訊號的傳遞，用以防止數位訊號、影像數據的非法複製。 That is to say, the EDID signal of the display device D1 is read by the EDID simulation unit 10, the EDID signal cannot pass through the display data message channel DDC, and the analog EDID signal is generated by the EDID simulation unit 10 to the multimedia host PC. In addition, the high-definition digital content protection key can transmit the signal of the high-quality digital content protection key technology between the multimedia host PC and the display device D1 by displaying the data message channel DDC, thereby preventing digital signals and images. Illegal copying of data.
值得一提的是，當「多媒體主機PC、轉換裝置1及顯示設備D1」之轉換系統架構完成時，多媒體主機PC會透過顯示數據訊息通道DDC的一串列資料傳輸路徑及一時脈訊號傳輸路徑，以同步編碼格式傳輸資料訊號及時脈訊號。其中，資料訊號根據時脈訊號被同時解碼。 It is worth mentioning that when the conversion system architecture of the multimedia host PC, the conversion device 1 and the display device D1 is completed, the multimedia host PC transmits a serial data transmission path and a clock signal transmission path through the display data message channel DDC. The data signal and the time signal are transmitted in the synchronous coding format. The data signal is simultaneously decoded according to the clock signal.
因此，多媒體主機PC可經由EDID模擬單元10取得一模擬EDID訊號(即一模擬擴充顯示器識別資料訊號)。然而，於多媒體主機PC取得模擬EDID訊號後，多媒體主機PC以間隔數秒一次的週期進行高畫質數位內容保護金鑰的訊號的傳遞，用以防止數位訊號、影像數據的非法複製。 Therefore, the multimedia host PC can obtain an analog EDID signal (ie, an analog extended display identification data signal) via the EDID simulation unit 10. However, after the multimedia host PC obtains the analog EDID signal, the multimedia host PC transmits the signal of the high-quality digital content protection key in a cycle of a few seconds, to prevent illegal copying of the digital signal and the image data.
此外，第一轉換單元11透過一最小化傳輸差分訊號通道TMDS電性連接第二轉換單元12，且第一轉換單元11經由最小化傳輸差分訊號通道TMDS，以傳輸HDMI訊號給第二轉換單元12。其中，第二轉換單元12將HDMI訊號轉換為DisplayPort訊號，並經由DisplayPort輸出埠DP2輸出給顯示設備D1。所以，顯示設備D1顯示多媒體主機PC所提供的影音訊號。 In addition, the first conversion unit 11 is electrically connected to the second conversion unit 12 through a minimized transmission differential signal channel TMDS, and the first conversion unit 11 transmits the HDMI signal to the second conversion unit 12 by minimizing the transmission differential signal channel TMDS. . The second conversion unit 12 converts the HDMI signal into a DisplayPort signal and outputs it to the display device D1 via the DisplayPort output 埠 DP2. Therefore, the display device D1 displays the video and audio signals provided by the multimedia host PC.
基於上述，除了第一及第二轉換單元11、12，轉換裝置1內部係為處理HDMI規範的電路、韌體或其他相關電子元件。其中，轉換裝置1係運用HDMI規範中的最小化傳輸差分訊號通道TMDS及顯示數據訊息通道DDC。最小化傳輸差分訊號通道TMDS係用以傳輸影音訊號。而顯示數據訊息通道DDC係用以傳輸EDID訊號及高畫質數位內容保護金鑰。 Based on the above, in addition to the first and second conversion units 11, 12, the conversion device 1 is internally a circuit, firmware or other related electronic component that processes the HDMI specification. Among them, the conversion device 1 uses the minimized transmission differential signal channel TMDS and the display data message channel DDC in the HDMI specification. The Minimized Transmission Differential Signal Channel TMDS is used to transmit video and audio signals. The display data message channel DDC is used to transmit the EDID signal and the high quality digital content protection key.
於顯示數據訊息通道DDC處於訊號連通狀態時，高畫質數位內容保護金鑰經由顯示數據訊息通道DDC，以進行多媒體主機PC與顯示設備D1之間的高畫質數位內容保護金鑰技術的訊號傳遞，用以防止數位訊號、影像數據的非法複製。於EDID模擬單元10接收到EDID訊號時，EDID模擬單元10控制開關16截止，並輸出一模擬EDID訊號給多媒體主機PC，以使多媒體主機PC取得顯示設備D1的模擬EDID訊號，藉此多媒體主機PC與顯示設備D1之間透過轉換裝置1可正常運作。 When the display data message channel DDC is in the signal connection state, the high quality digital content protection key is transmitted through the display data message channel DDC to perform the signal of the high quality digital content protection key technology between the multimedia host PC and the display device D1. Transfer to prevent illegal copying of digital signals and image data. When the EDID analog unit 10 receives the EDID signal, the EDID simulation unit 10 controls the switch 16 to be turned off, and outputs an analog EDID signal to the multimedia host PC, so that the multimedia host PC obtains the analog EDID signal of the display device D1, thereby using the multimedia host PC. The transmission device 1 can operate normally with the display device D1.
圖2為本創作另一實施例之轉換裝置之功能方塊示意圖。請參閱圖2。其中，圖2與圖1中的轉換裝置1、1a二者架構相似。而轉換裝置1、1a二者的差異在於：轉換裝置11a更包括一處理器P1及一操控單元18。 2 is a functional block diagram of a conversion device according to another embodiment of the present invention. Please refer to Figure 2. 2, the conversion devices 1, 1a in FIG. 1 are similar in structure. The difference between the conversion device 1 and the 1a is that the conversion device 11a further includes a processor P1 and a manipulation unit 18.
在實務上，操控單元18電性連接處理器P1。其中，EDID模擬單元10整合於處理器P1中。在其他實施例中，EDID模擬單元10亦可為單獨存在的個體，並電性連接處理器P1。本實施例不限 制轉換裝置1a的態樣。 In practice, the control unit 18 is electrically connected to the processor P1. The EDID simulation unit 10 is integrated in the processor P1. In other embodiments, the EDID simulation unit 10 can also be a separate entity and electrically connected to the processor P1. This embodiment is not limited The aspect of the conversion device 1a.
操控單元18用以接收一操控指令，並傳輸給處理器P1。處理器P1根據操控指令以切換開關16的導通或截止。在實務上，操控單元18例如為按鍵、切換開關、紅外線操控介面或藍牙操控介面。本實施例不限制操控單元18的態樣。因此，使用者可操控操控單元18，以控制開關16的導通或截止。 The manipulation unit 18 is configured to receive a manipulation command and transmit it to the processor P1. The processor P1 switches the on or off of the switch 16 according to the manipulation command. In practice, the control unit 18 is, for example, a button, a toggle switch, an infrared control interface or a Bluetooth control interface. This embodiment does not limit the aspect of the manipulation unit 18. Therefore, the user can manipulate the manipulation unit 18 to control the on or off of the switch 16.
此外，使用者亦可透過操控單元18以自行設定轉換裝置1的通訊金鑰，或是設定多媒體主機PC與顯示設備D1之間的通訊金鑰。例如，轉換裝置1具有多組高畫質數位內容保護金鑰，而使用者透過操控單元18以選擇多組高畫質數位內容保護金鑰的其中之一。而處理器P1根據操控指令以切換多媒體主機PC與顯示設備D1之間的通訊驗證運作。其餘部分均相同，在此不予贅述。 In addition, the user can also set the communication key of the conversion device 1 through the control unit 18 or set the communication key between the multimedia host PC and the display device D1. For example, the conversion device 1 has a plurality of sets of high-definition digital content protection keys, and the user uses the manipulation unit 18 to select one of a plurality of sets of high-quality digital content protection keys. The processor P1 operates to verify the communication between the multimedia host PC and the display device D1 according to the manipulation command. The rest are the same and will not be repeated here.
綜上所述，本創作為一種轉換裝置及其轉換系統，透過第一轉換單元以將DisplayPort訊號轉換為HDMI訊號，並運用HDMI規範中的最小化傳輸差分訊號通道及顯示數據訊息通道。其中，最小化傳輸差分訊號通道係用以傳輸影音訊號。而顯示數據訊息通道處於訊號連通狀態時，高畫質數位內容保護金鑰經由顯示數據訊息通道以進行多媒體主機與顯示設備之間的高畫質數位內容保護金鑰技術的訊號傳遞，用以防止數位訊號、影像數據的非法複製。於EDID模擬單元接收到EDID訊號時，EDID模擬單元輸出一模擬EDID訊號給多媒體主機，以使多媒體主機取得顯示設備的模擬FDID訊號，藉此多媒體主機與顯示設備之間透過轉換裝置可正常運作。如此一來，本創作確實可提升轉換裝置及其轉換系統之影音播放及顯示的使用方便性。 In summary, the present invention is a conversion device and a conversion system thereof, which converts a DisplayPort signal into an HDMI signal through a first conversion unit, and uses a minimized transmission differential signal channel and a display data message channel in the HDMI specification.
