These options are used only when encoding with a fixed bitrate 这些选项被用在固定比特率录入码流时。
Abr has a variable bitrate for each frame , but its average bitrate is a constant Abr则是每个帧都有一个可变的比特率,但是其平均比特率是恒定的。
So , great emphasis is put on the very - low - bitrate ( vlb ) video compression techniques 如此低的目标码率要求,向数字视频压缩技术提出了新的挑战。
Vbr means that the stream ' s bitrate is variable , and changes in according to the amount of information that needed to be encoded Vbr表示音频流的比特率是可变的,依据需要编码的信息总量改变。
Results of simulation experiment prove its better performance in improving picture quality and reducing video stream bitrate 并通过仿真试验验证了在提高图像质量和降低视频流码率上有较好的效果。
With complete audio converter lite all of the format parameters like frequency , bitrate , channels , etc . can be configured 具有完整的音频转换器建兴所有的格式参数,如频率,比特率,渠道等,可以配置。
5 video coding for low bitrate communication . itu - t recommendation h . 263 standard , nov . 1995 . 6 advanced video coding for generic audiovisual services 为了充分地利用存储带宽,减少不必要的开销,本文推荐了一种高效的重构图像存储映射机制。
In this thesis , the appropriate techniques for the compression of the monitoring video , aiming at the bitrate lower than 10kbps ( typically 9 . 6kpbs ) , is studied 本文,对码率低于10kbps (典型9 6kbps )的监控场景视频的甚低码率压缩技术进行了专题研究。
Along with the development of multimedia , image processing and computer network technologies , most of the largest companies are marching into the market of low bitrate video products 随着多媒体、图像处理、计算机及网络等技术领域的进展,通信已发展到视频通信阶段。
H . 263 is mainly used in low bitrate and low demand on picture quanlity occasion while mpeg - 2 is used in high bitrate and low demand on picture quantity occasion 263主要应用在低码率、对图像的质量要求不是特别高的场合, mpeg - 2主要应用在高码率、要求高清晰度图像质量的地方。
