These standardized communication protocols enable interoperability between vendor implementations. We have found that every part of the Internet and the local area network uses these protocols for implementing UPnP, so the knowledge of how to implement and deploy solutions based on these protocols is quite popular. Because they all use the same protocol, UPnP devices can operate in the existing network environment without having to take other actions. The communication between the UPnP support device and the control point is provided by the network medium, the Tcp/ip protocol suite and the HTTP to provide basic network connections and necessary addressing. On top of these open standard Internet protocols, UPnP defines a set of HTTP servers that specialize in exploration, description, control, event, and rendering operations. [Prior Art] Referring to Figure 1, Figure 1 is a schematic diagram of a conventional UPnP protocol stack. This is defined by the UPnP vendor, the "UPnP Discussion Working Committee" and the "upnp device architecture" document. The top-level communication protocol used to implement UPnP is defined. The work committee defines the specifications for device types such as VCRs, HVAC systems, dishwashers, and other household appliances based on the device architecture, and allows the "UPnP device manufacturers" to add device-specific materials such as model names and foxes. The TCP/IP network protocol stack is the basis upon which other UPnP protocols are based. With this popular standard TCP/IP protocol suite, UPnP leverages the functionality of a protocol, spans different physical media, and enforces interoperability across multiple vendors. UPnp devices can use many communication protocols in TCP/IP stacks, including TCp, UDP, IGMP, ARP, and IP, as well as TCP/IP services such as DHCP and DNS. TCP/IP provides a network connection between UPnP devices by means of a basic communication protocol stack. The success or failure of HTTP on the Internet is also a major part of UPnP. At every level of UPnP, HTTP or its 1257783 variant is the main architecture. In the US patents US2002/0027569A1 and US2001/0053274A1 and US2002/0180579A1, there is a user interface developed in accordance with this architecture, but the main point is still limited to the use of a screen connected by a computer host as an operation interface, and thereby The generated control interface does not conform to the usage habits of the average person using the remote controller alone. [Invention] In addition, the most direct way for the general manufacturer is to create an infrared transmitter with the required buttons (like the remote control for general household appliances) for the functions to be provided, and then install it on the personal computer. An infrared receiver through a hardware interface such as USB (Universal Serial Bus), pS/2 (Pers〇nal System/2), ISA (Industry Standard Architecture) PCI (Peripheral Component Interconnect) connects signals to a personal computer, and then uses software to connect the actions of these buttons with the operation of the application. However, this approach does not have much benefit in terms of cost considerations or ease of use, although it gives the user an extra choice in the use of the original remote control. Therefore, the present invention is directed to the above-mentioned problem, and by means of the operation of a personal digital assistant, a pure software is used to execute a jpnp "virtual remote control device" on a home personal computer, so that a device connected via a wireless or wired network is used. You can control the functions provided by your home PC by operating this “virtual remote control device.” Refer to Figure 2. Figure 2 is a schematic diagram of the UPnP protocol stack of the present invention. HTTPU (and HTTPMU) is HTTP. A variant of the Hyper Text Transfer Protocol, which is designed to deliver messages over UDP/IP (rather than TCP/IP). These protocols are used by SSDP and will be described later. The basic message format used by the protocol is closely related to the HTTP format. This format must be used when multicasting, and when the message delivery does not require additional costs to enhance reliability. 1257783 SSDP(Simple Service Discovery Protocol, a simplified service discovery protocol), as the name suggests, is primarily about defining how it is on the network. SSDp is a method based on HTTPU and HTTPMU to allow control points to find interested resources on the network and let the device announce their availability on the network. SSDP defines the search requirements and presence announcements. In this way, the cost of using only one of the mechanisms is eliminated. Therefore, each control point on the network can reduce the amount of network data and maintain complete network status information. The control points and devices are all SSDP. When the UPnP control point is started, it will transmit an SSDP search request (via HTTPMU) to explore the devices and services available on the network. The control point can narrow the search range and only look for certain types of devices (such as VCR), some sort of device. Type of service (such as a device that performs a clock service), or even a device. The UPnP device will answer the multicast connection. As soon as the search request is received, the device will check the search conditions to determine if they match. Finding a matching item will send a unicast SSDP (via HTTPU) field to the control. Similarly, the device is After entering, and after the road, a number of SSDP presence announcements will be sent to inform everyone which services it supports. The presence and unicast device response messages contain _ indicators indicating the location of the device documentation. Contains information related to (4) capacity and service collection supported by the device. GENA (Generic Event Notification Architecture)

On the other hand, almost any kind of structured data can be placed in the text file. .XML looks a lot like HTML, because it also uses tags and attributes. In fact, the two are quite different, because these tags and attributes are not defined according to their meaning, but are interpreted according to the context. The functionality can be developed for a variety of file types. The use of XML as an architectural language is defined by the W3C. XML devices and services The main part of the upnp used for the description, control messages, and event jobs. Based on the stack described above, the architecture or template is first defined by the UPnP device architecture to establish device and service descriptions for any device or service type. Standardize various devices and service types, and create a template for each device or service type. Finally, the manufacturer fills in the template with the exclusive information of the device or service, such as the device name, model number, manufacturer name, and The URL to the service description. This information is encapsulated in the UPnP-specific communication protocol and is defined in the "uPnP Device Architecture" file (such as the XML Device Description Template). The necessary UPnP-specific information is first inserted in all messages, then formatted using SSDP, GENA, and SOAP, and delivered via HTTP, HTTPU, or HTTPMU. [Embodiment] Referring to Fig. 3, Fig. 3 is a diagram showing the use of the present invention. Under this architecture, a media center supporting the UPnP console function is built in the computer host to simulate an existing Windows operating system and an input mode acceptable to the media center, and is connected to the UPnP virtual remote control host by signal. The software module simulates the operating system of the user's input mode. In this way, we can use an operating device, such as a personal digital assistant, or a notebook computer, or a tablet computer, to build a virtual if control driver in the system using the operating device, when the user clicks on the operating device If the virtual remote control driving mode transmits the received signal through the wireless network, the control message corresponding to the signal is sent to the virtual 1557783 remote control device host software module. When the virtual remote controller host software module receives the control message, the virtual remote control driver reduces the analog input device corresponding to the control message and transmits the input program to the operating system and the application software. The application software executes the input program; the virtual remote controller host software module outputs the result of executing the input program to an audio video device through the wireless network. The audio frequency video device includes at least a receiver and an audio video output device, and the receiver receives an input signal from the virtual remote control host module in the wireless network, and the audio video output device outputs the input signal. The receiver can also be independent of the audio video device in the form of a Set-Top Box and output the received audio video signal to the audio video device through the transmission line. Referring to Figure 4, Figure 4 is a diagram showing the processing architecture of the present invention under the UPnP architecture. In the present invention, two main software modules are added to the Windows 0S operating system to complete the overall operating procedure. One of them is a virtual remote control host software module (220). In this section, the present invention produces a virtual remote control device (software-based remote control device) in accordance with the UPnP standard. This system is constructed in the built-in UPnP protocol stack (13) provided by the window control system, and the window control system includes the IP shown in FIG. TCP, UDP, HTTP, HTTPU, HTTPMU, SSDP, and GENA. And it will follow the UPnP basic architecture to perform functions such as Addressing, Discovery, Control, and Eventing. In the virtual remote controller controlled by the software of the present invention, the button service is used to allow the user to control the object to be remotely controlled on the upnp control terminal through the network. After the virtual host remote control host module (120) receives the user's command through the network at the remote end, the module is transmitted with the following module, and the input mode is generated by the application software under the operating system. (input. 1257783 One is the virtual remote HID (Human Interface Device) driver module (240). ^ In the Windows operating system, all input devices (such as keyboard, mouse, IR receiver, etc.) After entering the core module (Kernel Mode) through the HIDCLASS.SYS (210) system module, a standard driver (23〇) is commercially available to signal the module and wireless network transfer H (320). If you use the fresh cranes, the application software of the Windows operating system can generate a separate device (device-independ (4) screen to correspond to the user's input, the corresponding screen can be presented according to different hardware devices. Different patterns. Therefore, by writing a specific _driver module (that is, the virtual remote drive driver module) (10), it is possible to simulate the generation of a current Windows operating system. And the input mode (i_t events) that the existing application software (including MediaCenterPCShell) can accept in order to meet the requirements of the above standard interface HIDaASS SYS (21()). On the other hand, the slogan is connected to the above UPnp virtual. The remote control device host soft module (220) is used to determine which operating system is to be input to the user's input mode. As for the extended use mode and extension concept of the remote control keyboard, if the user wants to use the virtual remote control keyboard Instead of transmitting _ remote control n, at the same time not light virtual remote control keyboard on the actual hardware, the simple definition of the above 101 102 Ρ Ρ 全 全 全 全 全 全 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 101 The gift control system uses the (four) device and the search in the service to find a full-featured virtual keyboard device for use. The user can press and press any button presented in the virtual keyboard device to generate and press. Entity (four) phase _ miscellaneous effect. - Received instructions from the virtual keyboard device, through the turn 'virtual remote wire field soft woven can be with the virtual remote HID drive The program (240) communicates with the signal. In the virtual remote HID driver module (24〇), it will be a virtual (10) (210) virtual full-function keyboard, just like the keyboard driver in the standard area ( Standard L〇Cal USB Keyboard Driver) is generally performed. The difference is that the signal typed by HIDCLASS.SYS (210) in 1257783 will be received by the UPnP virtual remote controller host software module (220) without Received by the physical keyboard. From the perspective of the window operation interface and the application software, this is a device-independent picture corresponding to the user input, regardless of where the user's instruction comes from, whether it is from an entity in the area. The keyboard is good, or it can be from the above two software modules through the network. UPnP is an industry standard. After executing this software on our home PC, we can use the "Advertisement" function defined in UPnP to display this "virtual remote control" in the WLAN (Wireless Local Area Network). The existence of the device. Any device that supports the UPnP Control Point function, such as a PDA (Personal Digital Assistant) 'Tablet PC' or even other desktop computers, can connect to this network. This "virtual remote control device" is automatically discovered and can be used further, that is, the function of remote remote control on a home PC. In the embodiment of the present invention, a virtual remote device under the UPnP architecture is implemented by a personal computer with a Media Center and a personal digital assistant. In the present invention, the virtual remote control device host software module (22〇) and the virtual remote control HID driver module (240) are applied to a personal computer having a media center (11〇), and UPnP is used. The control point (UPnP Control Point) software is built on the virtual remote control device (120) under the UPnP architecture, that is, the personal digital assistant, and then the personal computer with the media center (110) and the personal digital assistant (120) are connected to the home wireless. In the network (for example, 802. lla/b/g). When the above personal computer is activated and its corresponding virtual remote controller host software module (220) and virtual remote control hid driver module (240) are activated, the advertisement function defined by UPnP can be used to know the debt. That is, the virtual remote control device under the (5) architecture. Then, launch the above personal digital assistant to enter the range of 1257773 covered by the home wireless network, then the personal digital assistant will start searching for available UPnP devices in the network under the UPnP agreement, thereby Finding the virtual remote control device, and then further displaying the service options obtained through the virtual remote control device on the screen of the personal digital assistant and displaying the user interface (sometimes presented in HTML format), thereby using the user's instruction The above device is used to transmit to an IR receiver (31〇) in the home wireless network environment. Referring to Fig. 5, Fig. 5 is a view showing an operation screen displayed on the screen (401) of the personal digital assistant body (4〇〇). In the embodiment, the screen of the virtual remote controller (4〇2) is graphically displayed on the screen (4〇1) of the personal digital assistant in a pattern having a plurality of virtual keys. With the virtual remote control (4〇2) of the full-featured button presented on the personal digital assistant screen (401), the user can hold the personal digital assistant body (400) in one hand, and the other hand directly clicks on the individual with the stylus. The button of the virtual remote control (4〇2) on the digital assistant screen (4〇1). When the user clicks the button on the personal digital assistant screen (4〇1), the built-in control point software of the personal digital assistant will transmit the message through the wireless network, and the message is built on the personal computer. The UPnP virtual remote control host software module (22〇). When the above-mentioned virtual remote control device host software module receives the user's instruction. For example, when the user clicks a start button (41〇), the upnp virtual remote controller host software module (220) will send a message to cause the virtual remote control driver (24〇) to simulate a button, and the click action is input. The program is transmitted to the operation button and the pulse body to perform the action of turning on the power at the same time after the input command of the keyboard click action of the above-mentioned simulated start button (410) is received by the application software. For example, when the user clicks on a PLAY button (42〇), the 遥控ρηρ virtual remote controller host soft group age (four) message causes the virtual remote data (10)) to be difficult - a keyboard click action input program, and Outgoing to the operating system and application software to be executed. Thereby, when the application software receives the input command of the keyboard click action of the above-mentioned pLAY button (10), the job is called with the line. 12 1257783 In this control mode, it is not necessary to confirm where the user's instructions come from. In other words, the user's instructions can come from the infrared remote control of the home entity, or as in the actual example, click on the individual. The virtual remote control on the digital assistant screen (4〇1) is used for playback and other functions. In this way, the user can enable his personal digital assistant (4 (9)) to achieve the purpose of the virtual wireless remote control through the functions of the wireless network and the personal computer. This idea can be further extended to a “virtual wireless keyboard” or other general PC input device for operating all other functions on a home PC.
