The filter decompresses content as it comes across the wire before it hits the servlets and jsp pages , and then takes the response content and converts it into a compressed format before sending it on to the client machine ：过滤器在内容通过线路传来并在到达servlet和jsp页面之前解压缩该内容，然后再取得响应内容，并在将响应内容发送到客户机机器之前将它转换为压缩格式。
In the post - process , uses the microsoft medias technical to design cartoon display mode , it raises cartoon speed and saves disc space , it can produce majority prevailing medias form . in interpolation , introduced dsi method , which improve the interpolation method of isoline , raise algorithm speed and efficiency , satisfy the real - time quality request . on the basis of scanning line algorithm , use opengl smooth interpolate method to improve the implementati 在后处理过程中，引进了dsi插值方法，改进了以往等值线插值，提高了算法速度和效率，满足了实时性要求，在扫描线算法的基础上，引进了opm沁l插值方法，改进了云图实现方法，提高了图形显示精度，在动画格式上，我们可以根掘自己需要实现不同精度的不同压缩格式动画文件，提高了后处理显示应用场合，改变了以往动画格式单一的形式。
According to the characteristic of ieee 1394 with wide bandwidth , common and real - time , the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite . before engineering realization , carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface . we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4 . 5m to 100m ) , compared with analog videos , have no geometric distortion , and have better luminance , contrast , definition 作为工程实现前的实验研究，对三类具有ieee1394接口的数字录像机和摄像机进行了视频图像传输实验，发现无压缩格式的按ieee1394标准传输的数字视频图像(传输距离从4 . 5米到100米之间) ，较原始模拟视频图像在几何位置信息上没有衰变，而在亮度、对比度、边缘清晰度这些方面有明显的优势；但是按dvcam压缩格式(常见于sony公司的系列产品，是5 ： 1的dct帧内压缩)压缩的数字视频图像，较原始模拟参照图像有明显的几何畸变。
Furthermore , in the second part , the author makes a deeply discussion and research on the design scheme of dalian tv station non - linear av editing network including the double - net framework , the digital compress technique , the virtual storage technique , the choices of digital compress format , the account of terminal stations , the manage functions and security of the system , etc . finally , in the third part , the author introduces the progress of non - linear av editing network in the future , showing the choices of compress format , software function , i / o interface , whole system of programming and broadcast , combining with internet and interactive tv , points out the direction of tomorrow tv technology system 在此基础上，随后在文章第二部分对大连电视台的非线性视音频编辑网建设从其核心技术与具体网络设计方案进行了详细的阐述。其核心技术主要包括双网结构、数字压缩技术、虚拟存储技术等；具体网络设计方案则包括数字压缩格式的选择、站点的数量及功能、系统的管理功能及安全性分析等几个方面。文章的第三部分则主要通过压缩格式选择、软件功能、上下载接口、制播一体化、与internet结合、交互电视等方面展开对电视台非线性编辑网络的发展的论述，指出未来电视技术系统的发展方向。
