Problems solved by technology
[0006] The defect of the former is that embedded display terminals such as projectors have good display performance, but due to limited processing performance, the installed document processing software is limited, so various documents cannot be processed.
The defect of the latter is: on the PC, various office software documents are displayed in full screen, and on the personal terminal, due to the limited display screen, only a part of the document can be displayed or a document with a different display ratio from that of the PC (if such as a PC As above, if the document is displayed in full screen, it cannot be read)
The above-mentioned prior art does not disclose the method of rasterizing and encoding various documents on the mobile terminal into pictures through the method of virtual display, and transmitting them to the embedded display terminal
Moreover, in the above-mentioned prior art, the PC terminal rasterizes the obtained content into pictures, and the generated pictures are generated according to the display requirements of the PC terminal, and only need to use the display output method of the PC terminal itself, without considering different mobile Differences in Terminal Display Requirements

The present invention provides an analog display transmitting method of the content of the file, and the method is used in a system including the personal hand-hold terminal and the flush type display terminal. The present invention is characterized in that the personal hand-hold terminal captures the content of the file in the current page according to the operation command, and according to the display characteristic information of the flush type display terminal sent by the flush type display terminal, to create the image of the file content of the current page, and send the image to the flush type display terminal; and the flush type display terminal receives the image and plays the image.
Description
technical field [0001] The invention belongs to the technical field of computers, and relates to a method for transmitting and displaying various office documents on a personal hand-held terminal to an embedded display terminal through a virtual display method. Background technique [0002] At present, with the wide application and function enhancement of personal mobile terminals (such as PDAs, mobile phones, etc.), the original various office software on fixed terminals, including document processing software (such as WORD), report software (Excel), mail, web pages, etc. All can be browsed on the mobile terminal, but due to the poor display function of the mobile terminal, the display effect cannot reach the display effect on the PC terminal. [0003] Embedded display terminals refer to devices such as projectors, set-top boxes, and TV terminals. These devices are characterized by relatively strong video (picture) decoding and display capabilities, but because they are emb...
