摘 要
隨著信息技術的不斷發(fā)展，人們將計算機技術引入視頻采集、制作領域，傳統(tǒng)的視頻領域正面臨著模擬化向數(shù)字化的變革，過去需要用大量的人力和昂貴的設備去處理視頻圖像，如今已經(jīng)發(fā)展到在家用計算機上就能夠處理。多媒體通信技術的發(fā)展為信息的獲取和傳輸提供了豐富的手段，視頻數(shù)據(jù)是其中不可缺少的重要組成部分，而視頻數(shù)據(jù)的獲取離不開視頻采集系統(tǒng)。
Video for Windows庫函數(shù)(VFw)是Windows環(huán)境下的視頻開發(fā)工具，可以以純軟件的方式對實時視頻信號的捕獲和壓縮與解壓提供一種“黑箱”處理手段，大大方便了多媒體工程技術人員的編程開發(fā)工作。VFW視頻捕捉系統(tǒng)，用VC開發(fā)的程序，讓你可以試一下VFW視頻捕捉。靈活地運用VFw所提供的函數(shù)、宏、結構、回調(diào)函數(shù)以及編解碼技術將圖像數(shù)字信號進行壓縮處理通過網(wǎng)絡傳輸發(fā)送出去，能實現(xiàn)實時視頻傳輸?shù)男枰?br />
關鍵詞： VFw，視頻采集，壓縮，編解碼，網(wǎng)絡傳輸
Abstract
As information technology continues to develop, they will be bring the computer technology into the video acquisition and production areas, the traditional areas are faced with a video simulation of the digital revolution, in the past, there are needs a lot of manpower and expensive equipment to handle the video images, and now developing a home computer can handle these staff. The development of multimedia communications technology for transmission of information access and provide a wealth of tools, video data is an important and indispensable part, and getting access to video data can not be separated from the video acquisition system.
Video for Windows library (VFW) is the video under Windows development tools, software-only approach to the real-time video capture and signal compression and decompression to provide a "black box" means to deal with greatly facilitate the multi-media engineering and technical personnel for - Development work. VFW video capture systems, development of the VC process, so you can try something VFW video capture. Flexibility in the use VFW provided by the function, Acer, structure, function and callback codec technology to digital image compression signal sent through the network transmission, to achieve real-time video transmission needs.
Keywords ：VFW, Video Collection, Compression, Codec, Transmission Network
