[Embodiment] The embodiment of the detailed description of the present invention is disclosed herein, and the technology, system, and operational structure of the present invention are also diversified and different from the shape and mode of the revised May. The details of the implementation and the details of the implementation are only representative examples, and are defined as (4) 0 material _11 Tis Lai Xiao. According to the creation __金^^F<~~ embodiment, sharing and remote ί' feeding service 3 on an image desktop (for example, a fishcatcher that is controlled and sharing its desktop image) (for example It is to watch the desktop image of the server and transfer the keyboard (4) signal to control the computer of the feeding device. 'The two are connected by a connection device = such as μ line.' This connection (four) is placed on both ends with a usb connection: The connection device can promote desktop sharing and spring control between the feeder and the client. Refer to Figure 1 for May, which shows the overall configuration of the system. The computer of the server 12 and the computer of a client 14 are connected to a connection package by two USB types; 18a and 18b. Connection device: The ground has a small form factor. The two cables 18a and 18b may be integrally formed with the body of the connecting device 16, or may be physically separated cables and inserted into the respective connectors on the body of the connecting device 16, in combination of the above two. Referring to Fig. 2 in May, it is illustrated as a knot #图图 of the connecting device 16 of Fig. 1. The connecting device 16 includes a memory 22, a control circuit (for example, a micro-converter unit (MCU) 24), and a first communication controller (for example, a USB controller 26 for the server). And a second communication controller (for example, a USB controller 28 for the client) ^ USB cables 18a and 18b are respectively connected to the USB controller 26 for the server and the USB controller 28 for the client. The memory 22 stores the firmware of the MCU 24 and the two USB controllers 26 and 28, and stores a remote control program that can be executed by the server 12 and the client 14, respectively, which is attached to the detailed M379110 r-1; It. The MCU 24 controls the USB controllers 26 and 28 〇^TUU^2'4 i can transfer data between the USB controller 26 for the server and the USB controller 28 for the client, and processes the keyboard and slide from the client. The mouse data KB and MS are described in detail later. The USB controller % and 28 communicate with the server 丨 2 and the client 14 using a USB protocol. The USB controller 28 for the client simulates emulating - a USB CD-ROM device for use by the client 14. In other words, for terminal I4, the connection device π is the same as the CD-ROM that can communicate with the client client using Usb. For example, when the connection is set and inserted, the client's "My Computer window will be set to 16 CD. The device manager window will have additional USB mass storage devices. Similarly, the Servo=Output Controller 26 emulates a USB CD-ROM/keyboard/mouse^ for use by the server 12. In other words, for the server 12, the % device device 16 is identical to the USB protocol to the ship's core: this is a CD-ROM/keyboard/mouse mixing device. For example, when T communication is inserted, the "My Computer" window of the server will display and set the CD-ROM device of 16, and the "Device Manager" window will be displayed, outside the collar. USB mass storage device, an extra keyboard fish = a rat. In this example, although the slide controller for the USB controller of the server provides a keyboard device and a mouse device, alternatively, the camera module provides a keyboard device or a mouse device, which is Each analog ground is referred to as a user input device. Although the above-mentioned celestial CD.ROM is taken as an example, the controllers 26 and 28 can also simulate other η which are in conformity with the fine 1 SB control storage, and the 'quasi" 43⁄4 storage shock, for example. Dvd_r〇]^s, · portable. Dish, hard disk drive, or soft heart drive. Since gd_rqMs can provide convenient automatic execution (4), & is a better device for simulation. Due to the device provided for verification (USB CD-ROM,

USB CT)-ROM/keyboard/mouse is a standard device, and computers that perform common operating systems (such as Window, Mac, Linux, etc.) will be able to use the drive S-type and connection | Communicate without having to install special

Other drivers. The method of providing a USB CD-ROM device or a USB CD-ROM/keyboard/mouse mixing device is well known in the art and is not described in detail. The CD_R〇M device provided for the simulation of the server contains the energy-operated servo-12-end-end lung control. The CD-R〇M provided by this simulation preferably has an automatic execution program which can be implemented by providing an auto-execution file on the CD-ROM provided by the simulation. Thus, when the connection device 16 is inserted into the server 12, the server-side remote control program located on the CD-R〇M provided by the simulation will be automatically executed by the feeder, and the user does not have to perform- Independent program installation steps. The server-side remote control program instructs the server 12 to continuously transmit the video and audio data generated by the server 12 by writing the video (desktop image) and the audio data to the analog-provided CD-ROM device. To the connection device 16' and the Riley service 12 continuously read the keyboard and mouse data from the keyboard and mouse set provided. The word processor 12 uses this keyboard and mouse data to control its function. Similarly, the device provided for the client's simulation includes a client-side remote control program that can be executed by the client 14. The month 4 also includes an automatic function that allows the client to automatically execute the client. Execute the file. The client remote control program instructs the client 14 to continuously receive video and audio data from the connection device 16 by reading the video and audio data from the analog provided CD-ROM device. The client 14 applies this video and audio data to its screen and loudspeaker. In a preferred embodiment, the desktop of the server is displayed on the client's desktop in the form of a window (referred to herein as a remote control window). The client receives information about the resolution of the server desktop from the server, and the client draws this window and its contents based on this information. This remote control window can be dragged (or moved) and resized. In a preferred embodiment, the client remote control program creates the remote control window, and the actual rendering and management functions of the window are performed by the client computer's operating system. Alternatively, these functions can also be performed by the application software according to different program editing methods. The client remote control program can also instruct the client to obtain the keyboard and mouse events to be used on the server. For example, the client can determine whether there is a keyboard to be used to control the server computer based on whether the cursor is located in the remote control window and/or whether the window is the top (t〇p) window of the client desktop. Or a mouse event. This is also the function of the client's operating system. If the keyboard or mouse event is used in the servo device, the client will continuously transfer the keyboard and mouse data to the connecting device 16 in a manner that will be described later. When the video disk device is continuously transmitted to the guest 2 by the connecting device 16: = the keyboard and the mouse poor material are continuously transmitted in opposite directions, the image desktop sharing and the far word of the word server can be achieved. End control. The remote control program of the server and the client and the corresponding automatic execution M379110 file system are stored in the memory 22. 1 year Y-day double-vjSCT-s*·___j is not transmitted by the MCU 24 respectively. The USB controller of the server and the USB controller of the client. »Month continues with reference to Figure 2, which illustrates in greater detail the data transfer process between the server <RTIgt; The bulk transfer (buik-〇niy transport) between the host computer (server or client) and the simulated CD-ROM drive contains three phases. First, the host computer will be called the instruction block (c〇mmand)

One of the Block Wrapper, CBW) output packets is transmitted to the CD-ROM. The CBW contains a SCSI command, such as a CBW transfer data command from the server or a CBW read data command from the client. Then, the batch data (if any) is transferred. For example, if the host computer is a server, the output data 〇UT is transmitted, and when the host computer is a client, the input data IN is transmitted. After the data transfer phase, the host computer transmits an input packet ‘ and receives a Command Status Wrapper (CSW) from the USB controller indicating whether the data transfer was successful. Among the connection devices 16, the MCU 24 transfers the batch data from the USB controller 26 for the server to the USB controller 28 for the client. The video and audio data in the desktop sharing and remote control system according to the present invention is transmitted from the server 14 to the client via the simulated CD-ROM device in the manner of the above-mentioned batch data. On the other hand, the keyboard data KB and the mouse data MS are not transferred from the client 14 to the server 12 in batch data. Specifically, as shown in Figure 2, the keyboard and mouse data will be placed in the form of a packet by the client 14 in the CBW to be transferred to the USB controller 28 for the client. The MCU 24 processes this received by the USB controller 28 for the client. UA repair

: (4) Take out the (4) material, and wire (4) the wire to obtain the P lrUSB controller 26. The brain controller % for the word processor outputs keyboard and mouse data to the server 12' and is connected to the respective ends of the mouse via the USB keyboard provided by the simulation. Eight other information that needs to be passed from the client to the server (such as user configuration information, hardware information, etc.), can also be entered using the keyboard hotkey. For example, the 'Useable' button can be used to turn the audio on and off. When the user at the client presses the function key, the corresponding hot key signal ^, /, eight his keyboard = bedding is transmitted in the same way. The servo end remote control program located on the server responds after receiving the hotkey data. The keyboard and mouse data passed along with the SCSI commands in the CBW should be passed as described above, thus increasing the efficiency of bulk data transfer. The server and client operating system typically has a predetermined bandwidth for transferring data to and from a USB mass storage device, and reading or writing data can only be performed within a specified time period (ie, data). Flow in one direction for a specified period of time). If the video and audio data (from the server to the client) and the keyboard and mouse data (from the client to the server) are transferred in batches, the keyboard and mouse data passed in the other direction With relatively small capacity, the transmission of relatively large amounts of video and audio material in one direction will be broken up. This will reduce efficiency because the various stages (CBW, data, CSW) in the batch transfer are separated from the previous stage by two Start of Frame (SOF) (in USB 1.1). About 2 milliseconds (ms) 'and about 250 microseconds (us) in USB 2.0) (refer to Figure 3). For example, if M379110 sees %, even if only a small amount of data (such as keyboard data and mouse resources) is needed, it will take at least 6 milliseconds to be delivered. In view of the fact that in a SOF at the same time, it can transfer a lot of kilobytes (Kbytes, KB) of batch data (about 3KB can be transmitted in 2 milliseconds in USB 1.1, and about 15KB in 250 microseconds in USB 2.0). ), knowing that blocking data transfer will pay a considerable amount of overhead. Therefore, the transmission efficiency of video and audio data will be seriously affected by the transmission of keyboard and mouse data. In Figure 3, the events in the dashed box represent events from the client transferring the disc and mouse data to the simulated CD-ROM device. In a preferred embodiment of the present invention, such events do not occur and the batch data system can be delivered in almost one direction (from the server to the client, the CD_R0M provided by the simulation is used to use the maximum frequency). Wide to transmit video and audio data from the server to the client. In an alternative embodiment, the keyboard and mouse data are transmitted in batches, similar to the way video and audio are delivered. = The direction of the hand is reversed. This embodiment does not have the advantages as can be provided in the description of the above disclosure.

When the main unit is connected to the bribe 12, the server (10) B measures this event. Then, the bribe device cooperates with the connecting device 16 to store the volume storage device, the keyboard device, and the mouse device. Then, the controller 26 for the feeding device provides the remote control program of the file server to be presented on the mass storage device simulated, and the remote end of the server 12 is #4 (4) #, automatic 仃If the mass storage provided by this clothing department is not stored in the automatic execution of the building, then the user behavior will be carried out at 12 5 5M379110 to execute the remote control program. Next, under the control of the end control program, the server 12 will wait for a signal from the client 14 = to initiate data transfer (a keyboard or mouse command from an analog keyboard or mouse device). Then, if this _ = is received, the desktop sharing and remote control communication will be established. Then, the server 12 will start to perform the function of the server data transfer, including transferring the video/audio data to the connected device, and receiving the keyboard = mouse data from the connection I, and serving the H county to receive the keyboard and slide. Rats (4) come into other programs they have. Then, the ship H continues to do this:, the pause (for example, the connection device is unplugged), or the direct service aircraft ^!
