In the simulation , the redundancy - rate - distortion performance is analyzed , and results prove that this mdc has a better reconstruction performance than conventional single description coder ( sdc ) in error - prone environments 在仿真中，对该框架的冗余率失真性能进行了分析，结果表明：该多描述视频编码方法在易错环境中的性能优于传统的单描述编码方法。
Further , leveraging the same annotations for other purposes could prove error - prone , because the annotations will be attached with a very specific concern in mind instead of representing the state modification characteristics of the methods 而且，将同一个注释用于其他目的很容易出错，因为注释将要额外考虑特定的关注点，而不是考虑如何表示方法的状态修改特征。
However , distributed fault - tolerant applications are hard to be developed , since the programmers must handle not only the complex business logic but also the confused fault tolerance logic . the latter one is often tedious and error - prone 但是直接开发分布式容错应用是非常困难的，这是因为开发者不仅要处理复杂的应用逻辑，还要面对纷繁的容错逻辑，处理不好会弄巧成拙，容错成了“容易出错” 。
At present , there are several approaches to targeted gene disruption ( or gene targeting , as it ' s usually called ) that can be customised to attack anywhere in the genome , but they ' re all highly error - prone , disrupting other locations a great deal 目前，有几种方法可用于打靶的基因破坏（或称基因打靶，实际名称也是这样） ，它可以定制，用来攻击基因组的任何地方，但它们全都容易出错，在非常多的地方破坏其他位点。
Usually unsupported types are imported into the managed world as the generic , non type - safe intptr type , requiring error - prone and tedious marshaling code to use the assembly , but sometimes tlbimp . exe cannot expose members of an interface at all 通常，不受支持的类型作为泛型、非类型安全的intptr类型导入到托管世界中，并需要编写易于出错且冗长的封送代码以使用程序集，但有时tlbimp . exe根本无法公开接口的成员。
Another inconvenience of the default launch process is that the user must manually add configuration details such as classpaths , location of the client , and arguments for the client in order to get the client to launch successfully , which is an error - prone process 默认启动过程的另一个不便之处是用户必须手动添加配置细节信息，例如classpaths 、客户机的位置和客户机参数，以便成功启动客户机，这个过程很容易出错。
From the perspective of video content analysis , this dissertation proposes a content - based error control framework under the error - prone channel , exploring the strong correlation between video content , network resources and video quality . in this way , the author intends to combine the information processing technology and video transmission , aiming at solving the problem of error control in multimedia communication 本论文从视频内容分析的角度出发,提出了易错信道下基于内容的差错控制框架,发掘视频内容、信道差错与视频质量之间的相互关联,把内容处理、网络传输和编码技术结合起来,综合解决视频通信中的差错控制问题。
In the simulation , its redundancy - rate - distortion performance is analyzed firstly , then the performance of error concealment and error resilience , the coding framework proposed in this paper are tested and compared with the mdc based on pct and sdc in error - prone environments , the results testify that not only the proposed mdc scheme has a better robustness but also a higher coding efficiency , which ensures reliable transmission of compressed digital video over networks 在仿真实验中，首先对其冗余率失真进行了分析，然后和基于pct的mdc及传统单描述编码方法在有突发错误及丢包坏境中，对错误隐藏和错误复原等抗误码性能进行了比较，结果表明：本文的多描述编码在易错环境中不仅具有更优良的抗误码性能，而且编码效率较高，能够保证在网络上视频传输的可靠性。
Based on the analysis of some of current video coding technologies and the error - prone characteristics , the main works and conclusions in this thesis are listed as follows : ( 1 ) hybrid video scalable coding structure based on the analysis and research of the current several scalable coding schemes , a multi - loop independent motion compensation encoding structure integrated several existing standard scalability is proposed to provide a broader bitrate range to be adaptive the status of the network and to meet requirement of different level of quality of service , and improve the coding efficiency 本文在分析目前一些主流视频压缩编码技术的基础上，结合易错网络的特点，主要就以下三个方面对视频可分级编码进行研究： （ 1 ）混合可分级编码结构基于对现有主流混合可分级编码结构分析与研究，融合了目前主要的几种标准可分级编码技术，提出了混合多环独立运动补偿可分级视频编码结构，以提供较大的位率可变范围来适应不同的网络状况与视频服务质量要求，同时也提高编码效率。
