Description
本發明乃是關於一種USB對接裝置與其控制方法,特別是指一種USB對接裝置與其控制方法,可即時且自動地切換所連接之顯示裝置所顯示之第一電子裝置的螢幕畫面或第二電子裝置的螢幕畫面。 The present invention relates to a USB docking device and a control method thereof, and more particularly to a USB docking device and a control method thereof, which can instantly and automatically switch a screen screen or a second electronic device of a first electronic device displayed by a connected display device. Screen shot.
隨著USB介面漸成為標準介面的首選,USB介面的配置已成為可攜式裝置的基本規格要求。而USB介面的傳輸規範已由USB1.0、USB1.1延伸至USB2.0與USB3.0,甚至是USB3.1。由於USB介面最初便被定位在電腦與周邊裝置間相連接的一個介面,因此USB-IF協會在制定USB介面的基本架構時選擇了主從式(Master-Slave)的架構,以將較困難及較複雜繁瑣的工作都交給主機端(Host)來負責,如此一來裝置端(Device)之設計與開發的困難度就相對地降低了許多,使得製造廠商較容易設計USB介面的裝置。由於USB介面具有隨插即用與熱差拔的特性,使得適用USB介面之USB裝置的便利性大幅提昇,以至於幾乎在所有的主機裝置的周邊裝置上都可以看到它的應用。 As the USB interface becomes the first choice for standard interfaces, the configuration of the USB interface has become a basic specification requirement for portable devices. The USB interface transmission specification has been extended from USB1.0, USB1.1 to USB2.0 and USB3.0, and even USB3.1. Since the USB interface was initially positioned as an interface between the computer and peripheral devices, the USB-IF Association chose the Master-Slave architecture to make it more difficult to develop the basic architecture of the USB interface. More complicated and cumbersome work is left to the host (Host) to be responsible, so the difficulty of designing and developing the device is relatively reduced, making it easier for manufacturers to design USB interface devices. Due to the plug-and-play and hot-draw characteristics of the USB interface, the convenience of the USB device for the USB interface is greatly improved, so that its application can be seen on almost all peripheral devices of the host device.
除此之外,由於USB技術在裝置連接上已十分普遍且受歡迎,為了滿足不斷發展的設計趨勢,如:裝置尺寸設計趨勢,新的USB接頭規格USB Type-C接頭迎合了市場需求並為往後的USB接頭版本奠定了一個新基礎。USB Type-C接頭的尺寸為8.3×2.5毫 米,小於當前主機裝置之的USB接頭(USB Type-A接頭)的尺寸,但大於許多非主機裝置所採用之尺寸為6.85×1.8毫米的Micro-USB接頭(USB Type-B接頭)。由於USB Type-C接頭並不相容於現有的任何類型,因此需要額外地為其設計轉接裝置。 In addition, since USB technology is very popular and popular in device connection, in order to meet the evolving design trends, such as device size design trends, the new USB connector specification USB Type-C connector caters to market demand and The future version of the USB connector has laid a new foundation. The size of the USB Type-C connector is 8.3 x 2.5 millimeters. The meter is smaller than the size of the USB connector (USB Type-A connector) of the current host device, but larger than the 6.85 x 1.8 mm Micro-USB connector (USB Type-B connector) used by many non-host devices. Since the USB Type-C connector is not compatible with any of the existing types, it is necessary to additionally design an adapter for it.
