  1. Further investigated and analyzed composition structure and flow data that dsa ' s formation of image is systematic at first in this paper, carried on intact summing up to the data in the system, having given out the plan of design of high speed and large capacity data channel of digital formation of image system of x - ray ; deeper discussion of control way on sdram, give solution that many pieces of sdram works togetherses of realizing heavy capacity, designing of heavy capacity deposit board realize storing at a high speed to vision data by frame on the basis of this ; through further investigations of interface of pci bus, optimize back end state machine design and urge procedure making with lower, giving intact pci interface scheme that realize high speed dma data transmission and satisfy request of video transmitting ; further investigate the figure systematic design method of programmable logic devices, due to the difficult point of drifting about of enabled signal in fifo in common use and setting up and keeping of output signal, method has been proposed of improving stability of system making use of signal utilizing the phase locking ring in fpga to offer a lot of clocks to move thus realize coordinating the data between every module of system to transmit at a high speed by making use of fifo

    本文首先對數字減影血管造影（ dsa ）成像系統的組成結構和數據流向進行了深入研究和分析，並對系統中的數據流向進行了完整的歸納和總結，給出了x線數字成像系統中的高速大容量數據通道的設計方案；在對sdram的控制方式做了深入探討后，給出了實現大容量多條sdram共同工作的解決方案，在此基礎上設計了大容量幀存板實現對圖象數據進行高速存儲；通過對pci總線介面的深入研究，優化後端狀態機設計和低層驅動程序開發，給出了完整的pci介面方案實現高速dma數據傳輸，完全可以滿足視頻傳輸要求；深入研究了基於大規模可編程器件的數字系統設計方法，針對通用fifo使能信號漂移、輸出數據難于建立和保持等設計難點，提出了利用fpga中的鎖相環提供多個時鐘相移的信號來提高系統穩定性的解決方案，從而實現利用fifo來協調系統各模塊之間的數據高速傳輸。
  2. Three kinds of data access objects dao, rdo, ado and windows dna structure of three are discussed at length. integration mode of software system is summarized and a set of software is programmed on this basis to realize the database management of experiment data. in addition, another set of vod management system software is programmed to ensure its normal operation and effective management

    本文回顧了數據管理方式的發展歷史，對數據庫，特別是sqlserver2000進行了比較詳細的介紹，討論了三種數據訪問對象： dao 、 rdo 、 ado ，詳細討論了windowsdna三層結構，對軟體系統集成方法進行了概述，然後在此基礎上編制了一套針對實驗數據的數據庫管理軟體，實現了對實驗數據的數據庫管理，另外還在導師原有科研工作的基礎上，進行理論分析，並改進編制了一套視頻點播管理系統軟體，實際運行證明，可保證視頻點播系統的正常運轉和有效管理。
  3. After studied a great many of tcp - friendly congestion control protocols and the quality - oriented rate control methods in this thesis, we design a congestion control protocol rooted upon a specific application, to manipulate the output video rate of fgs - the scalable mpeg - 4 encoder. since the mpeg - 4 video streams consist of multi - objects, we present two rate control policies : one is priority - bl ( base layer ) based, the other is priority - object based, and the priority is decided by cb - tfrc taking account of the user ' s mind, thus we accomplish the content - based tcp - friendly rate control

    本文在研究了各種tcp - friendly協議和面向質量的速率控制方法之後，設計了一種與具體應用相關的擁塞控制協議cb - tfrc ，可以對mpeg - 4可伸縮性編碼器fgs的輸出速率進行控制，針對包含多個對象的mpeg - 4視頻流，提出了優先保證基層數據和優先保證對象的兩種速率分配策略， cb - tfrc可以根據用戶感興趣的內容，來決定採取哪種策略，從而實現基於內容的tcp - friendly擁塞控制。
