Embodiment
The present invention proposes transmission and the display system and the method thereof of a kind of image frame and cursor glyph.Wherein, transmission and display system have controlled end computing machine and manipulation end computing machine.In this transmission and display system, controlled end computing machine can be with the raw video data decomposition for not containing the image data and the cursor data of cursor data, and image data and cursor data are sent to the manipulation end computing machine respectively, in manipulation end computing machine show image picture and cursor glyph.Wherein, the raw video data are relevant to the raw video picture that comprises cursor glyph.
Please refer to Fig. 2, it shows according to the transmission of a kind of image frame of a preferred embodiment of the present invention and cursor glyph and the calcspar of display system.This transmission and display system comprise manipulation end computing machine 210 and controlled end computing machine 220.Manipulation end computing machine 210 is sent controlling signal D1 by mouse, with the controlled end computing machine 220 of Remote.Controlled end computing machine 220 comprises image frame acquisition unit 221 and cursor acquisition unit 222.Image frame acquisition unit 221 is according to the raw video data that comprise the raw video picture of cursor glyph, and output does not comprise the image data D2 of cursor glyph to manipulation end 210.Cursor acquisition unit 222 is according to these raw video data, and D3 is to manipulation end 210 for the output cursor data.After manipulation end computing machine 210 receives image data D2 and cursor data D3, image data is deciphered, shown the image frame that does not contain cursor glyph; And the processing cursor data, the cursor glyph that is relevant to cursor data is coincided on image frame.
Note that the transmission and the display system of the image frame and the cursor glyph of present embodiment, is to comprise that a manipulation end computing machine is that example explains.In practical application, the transmission of image frame of the present invention and cursor glyph and display system can comprise not only manipulation end computing machine, and each manipulation end computing machine is with the controlled end computing machine of mode Remote same as described above.
