The effect is hereby explained in detail by the following specific embodiments, as described later: In conjunction with the accompanying drawings, please refer to the first diagram, the first embodiment of the present invention.同步 The system of Synchronous Imaging System (PDA) and palmtop cloth 5V imaging system disclosed in the invention includes digital assistants 10, wired V, operating devices, and mobile phones with electronic brain functions. Device-type display device ... Below, there will be placed 14. Wireless τ Ke will further explain the components contained in each device and the interaction between each device. As shown in the first figure, the portable device 10 includes a motherboard 18 with a processor 20, a small display 28 for displaying audiovisual information, a wired receiving interface 2 for receiving control commands 2 and a wireless receiving interface 2 4, and transmitting audiovisual information. The wireless transmitter 26 and the first switching device 32 and the second switching device 30 that turn on / off the processor 20. The connection relationship between the above components is that the small display 28 is coupled to the processor 20 of the main board 18 and displays a video information. The wired receiving interface 22 is used to couple the processor 20 of the motherboard 18. The wireless receiving interface 24 is used to couple the processor 20 of the motherboard 18. The wireless transmitter 26 is used to consume the processor 20 of the motherboard 18 and transmit audio and video information. First switching device

1242155 V. Description of the invention

3 2 is used to turn on / off the small display. 2 switching device 3 〇 is used to turn on / off the coupling of the device 20. 28 is coupled to the processor 20. The first wireless display device 12 and processing. When the portable device 10 is through a wired receiving interface, a π-edge keyboard, a wired joystick or a wired. When the control command of 16 is set to 1 m, the portable device is £ 10. The processor 20 on the board 18 changes the audio and video information according to the control command.

I also changed the video and audio data displayed on the second portable 10 through the small display 28 and the wireless transmitter 26: the information will also change. ν Know the reason, when the portable device 10 is controlled by a wireless receiving interface such as a wireless mouse, a wireless keyboard, a wireless joystick or a wireless operating device such as a handwriting tablet When the command is issued, the video and audio information displayed by j = ”不 器 28 will also change, and the video and audio information transmitted through the radio will change. ^ Fan ^ 疋, in some special cases, the user It is possible to adjust the first switching step and the second switching device 30 to prevent the audio and video information on the small display 28 and the audio and video transmitted by the wireless transmitter 26 from being changed. That is, by the first The second switching device 30 cuts off the wireless transmission. Two = standing processing, and the coupling of 20 makes it impossible for the wireless transmitter 26 to transmit Zhitian Beixun. By the first switching device 32, the small display 28 is cut off and processed.

5. Description of the invention (5) The coupling of the benefit 20 makes the small display 28 unable to display the audiovisual information. As shown in the first figure, the wireless display device 2 includes a wireless receiver 3 4 = a large display 36. The wireless receiver 34 is used for receiving the audio-visual information transmitted by the wireless transmitter 26. The large display 3 is used to display the audiovisual information received by the wireless receiver 34. The above system is based on the large-scale portable device 36 on the device 28 to observe the portable device. This method uses the clear picture of the fine-screen device 12, and the information is the same as in this case. The display 28 is also the device 36 of the present invention, which can be displayed in a portable manner, so that the linear display can be synchronized, a large number of simultaneous display, small display display device as a device to operate a large display without using for. Such as suitable for reading to portable descriptions can be transmitted by wireless video and audio display 3 6. The device 10, a small display connected to its operation 10, can use a large display by the user of the device 10 of the present invention to display the device 10 of the present invention by the user of the operation device 12 to perform its operation. Like the system, input data to the local area Although the present invention has been disclosed as a preferred embodiment to limit the present invention, anyone skilled in this art can use various modifications and decorations without departing from the scope and scope.
