dc.description.abstract隨著網路的發展,單純的多媒體串流已經不能滿足使用者的需求,除了影音的傳送,使用者需要應用程式的分享,利用Client╱Server機制分享桌面,因此,終端服務的圖形壓縮為本論文的主題。 首先說明VNC、X Window以及RDP的差異,並分別比較其優缺點, RDP的圖形傳送方式採取不同的畫面使用不同的指令,在文字部分傳送1 bpp的點陣字型,圖形部分則傳送參數由Client端繪製,複雜的圖片則傳送bitmap,由於RDP以T.128為基礎,因此介紹T.128(Multipoint Applocation Sharing Protocol)的標準,對於畫面的命令處理方式T.128有特別說明指令的定義及相關參數。 在實驗環境以rdesktop為主體,藉由程式碼的修改,進行畫面指令的分析,透過實驗畫面的結果瞭解桌面圖形壓縮方式,為了驗證RDP的圖形壓縮方式適合使用在thin client的架構中,最後透過rdesktop進行資料量的分析。 本論文的重點在於遠端圖形傳遞上資料壓縮的分析,除了影片播放外,Window作業系統中的應用程式大多能順暢的操作,影片播放時由於畫面不斷更新,播放畫面越大資料量越多,忽略的畫面也越多,在Client╱Server的架構中,除了影片播放外,其他的應用程式畫面傳送都可以利用RDP連線進行資料傳輸,最後藉由實驗結果推論出RDP Server的畫面切割原理。zh_TW
dc.description.abstractAlong with the network development, multimedia sharing can not satisfy users. Except the video and music transmission, users need the application sharing. We can use client/server computing to share the application. This thesis is to discuss the desktop image compression. First, we will explain the difference between VNC (Virtual Network Computing), X Window and RDP (Remote Desktop Protocol).For image transmission, RDP server according to different display uses different order. For text transmission, RDP server sends 1bpp bitmaps to RDP client. For simple graphics transmission, RDP server sends a parameter order to client. When client receive an order it will draw a graphic on the window. For the picture transmission, RDP server sends bitmaps to client. RDP Protocol is based on T.128 (Multipoint Applicaion Sharing Protocol), so we introduce the T.128 Protocol. Our research is based on rdesktop program. We modify the source code, in order to analysis the display components. We use rdesktop to connect RDP server. During the transmission, we calculate the packets size from server. Besides video playing, other applications can get a smooth transmission. We demonstrate that using RDP protocol to deliver application images can get high performance in data compression.Finally, make a conclusion of terminal desktop image compression.en_US
