• It imposes some bad impact on video implement over network and imposes many challenges to the traditional nonscalable video coding technology which is not efficient for transmission video over the error - prone . then the scalable video coding technology was proposed , which can provide a rang of bitrate change and its redundant video content compensate the transmission error , but loss coding efficiency
  传统的不可分级编码技术已经不能满足视频在这类网络上的传输需要，就提出了可分级编码技术，它能提供一定的位率可变范围，同时因可分级性而带来的冗余信息也在一定程度上补偿了因传输误差而引起的视频内容的损失，但也因此而损失了编码效率。
• The algorithm introduced in this paper provides prospective psnr performance that is close to the fsbma . the algorithm tries to achieve better performance in terms of all three parameters in the speed - quality - bitrate tradeoff , so satisfies high estimation performance and efficient implementation and can be used for real time low bit - rate video coding
  这种运动估计方法性能上接近全搜索法和三步法，有较快的估计速度和较高的峰值信噪比，搜索效率高，在减少计算量的同时，保持较好的图像性能，因而是一种性能良好的运动估计方法。
• Based on dct domain r - d analysis , we provide a new constant bitrate ( cbr ) rate control algorithm , which can cure tm5 algorithm " two limitations , buffer conformance and scene cut problem . for variable bitrate ( vbr ) rate control , we proposed a single - pass vbr rate control algorithm for real - time video coding application
  对于vbr码率控制，作者还提出了一种面向实时视频编码应用的单通道vbr码率控制算法，它避免了多通道vbr算法的多次编码或预分析的开销，减小了量化步长波动，可提供稳定的视频质量。
• Compression of photo is a relatively difficult technology in 2d code . it ca n ' t leave big space for photo which influent its ability of storage . because the resume of compressed photo it requests relative low compressive ratio . roi ( region of interest ) ? ased embedded coding in the article is a technology which probably settle upper problem . it mainly has the following characteristics : 1 . allocate different bitrate to different region
  二维码qrcode中照片压缩是一个较难实现的环节，因为其留给照片的空间不能太大，否则影响存储能力，但又必须考虑到压缩照片的恢复问题，还需压缩比不能太高，文中提出的基于感兴趣区域的嵌入式编码方法是综合上述因素的一种比较理想的技术，它主要具有如下特点： 1
