Description of the Invention: [Technical Field] The present invention relates to a wireless projector', and more particularly to a projector including an embedded download server. [Prior technology], ·^4 1 is not flat / [苜汉,〇,汉/) into the life of 4 people> ancient, and the wireless LAN technology (Wireless LAN) technology is gradually mature, so on the market Existing manufacturers have developed wireless projectors, users no longer need to use the image transmission line to connect the client device (such as notebook or personal digital assistant PDA) and technology camera 'through the wireless network The video output from the client's device is transmitted to the downtime machine, which not only eliminates the connection of the image transmission cable, but also allows the notebook to send signals to multiple projectors, and to connect multiple channels to make multiple projections. The function can be synchronized. However, in order to connect with the wireless projector, the customer's wonderful machine #抱,, + installed such as transmission software and wireless projector __^^ Be first female projector, and each manufacturer's q cast f image transfer to the wireless body For a communication system that frequently travels to and from different fields, and that matches the transmission of each wireless projector; it must be safe; the general driver is a CD; Obviously, there are many optical disc drives that are externally stored. However, there is currently no way for the notebook computer to install the driver. If you forget to prepare the CD player, you will be able to use it. If the user uses a PDA, it will be even worse. The use of the wireless projection instead of causing the wireless connection of the wireless connection " / b installed by the CD-ROM software, so [invention] the lack of use of evil methods. The main purpose of the invention is to download the transmission software and the driver: a kind of driver for the client to immediately pre-install the wireless projector, so that the client device can realize the wireless without the work and the software. Pass 1254185 lost homework. To achieve this, the present invention provides an embedded servo in a wireless projector and preloads the transmission software and its driver software in the buffer, and this 支援ρ supports universal plug and play (UniVersal P1 _ (4) , through the built-in wireless communication module and group with standard wireless transmission protocol, and with wireless communication module: if u for wireless communication, providing client device instant download = spring „transport software and driver Therefore, any device with no client can download and install the pre-stored =, .spring projector_transport software and program directly through wireless communication, without pre-software and driver. And the wireless projector of the wireless projector - the purpose, the money for the test - the upgrade of the wireless non-i projection type upload to achieve the right. Order 1 person update or upgrade operation, increase the operation The convenience server can be used in black: the embedded servo provided in the wireless projector of the present invention can be used as the rear of the projector. For details and implementations of the present invention, BRIEF DESCRIPTION OF THE DRAWINGS [Embodiment] A block diagram f can include a $1 map, and a system function such as an optical module 10' according to a preferred embodiment of the present invention includes a basic functional component signal processing unit of the projector. The related image signal processing circuit 12 uses the image 2 to input image signals generated by the device 20 (such as a personal computer PC, a 1254185 number of assistant PDAs, and a notebook computer) from the client (see "Fig. 2"). The image is projected onto the projection surface through the optical engine; the servo module 30' is implemented by a wireless communication module according to a preferred embodiment of the present invention, and can be received by wireless communication. The image signal generated by the device 2 of the client is then transmitted to the image processing circuit 12, and in a preferred embodiment, the communication module further includes a wire communication unit 31. Both the wired communication unit 31 and the helmet line communication module follow a standard standard network protocol (netw〇r; protocol) such as the Internet Protocol (IP). The transmission control protocol (rpcp), uj) p User Datagram Protocol, Hypertext Transfer Protocol (http), etc. communicate with the client device 20, and, an embedded download server 40 (embedded download service) The embedded server 4 is preloaded with a transmission software and a driver for controlling the benefit line projector, and the client device 20 is established with the embedded server 40 through the communication module 30 of the server. The communication path is used to instantly download the transmission software and driver of the wireless projector. Taking the wireless LAN (IEEE 802.11b specification) as an example, it defines two wireless network operating modes: the special (Ad h〇c) mode and the infrastructure mode. In Ad h〇c mode (also known as peer-to-peer mode), wireless clients (C1 ient) can communicate directly with each other (no, use wireless access point - Access Point); if in base mode, different client devices It is necessary to communicate with each other through a wireless access point AP. According to this specification, when a wireless communication module in a client device 2 (such as a notebook computer or a personal digital assistant PDA) is started, it will start scanning (searching) the wireless frequency of the area in which it is located, and searching for wireless memory. Take the point (Access p〇int, Λρ) and the wireless client under other special modes (Adhoc). Assuming that the wireless client is not operating in the basic mode, the wireless communication module will select a hotline to be connected to the 1254185, and the process is generally the same as the 3 3 wireless adapter-wireless adapter. The set of identification words contained in the group (Service Set identl t into the type of f is the service through the service and the error rate information from the Gucheng) and the signal strength to the selected blood continued AP &> -, s, # The hot and spring communication modules will switch to all of this.

According to a preferred embodiment of the present invention, the communication module of the aforementioned servo end is not a wireless network area (wireless l〇cal area netw〇rk, wlan) For the sole embodiment, other wireless communication technologies that can achieve communication purposes are also possible. These communication technologies include: blue tooth communication technology, infrared communication technology (IrM); A possible implementation of the foregoing wired communication module can be implemented by some transmission converters (Jransmmer Adapter), such as a physical interface of USB or IEEE 1394, providing a connection port for the client device. Therefore, any device having a wireless communication module client can directly install the transmission software J and the driver stored in the wireless projector through wireless communication, without pre-installing the transmission software and the driver. The purpose of wireless communication with a wireless projector can be achieved. For the file transfer service of the transport protocol, the embedded download server can be: iilTP Server, FTP Server, or TFTP Server.
