码率控制是恒定码率视频压缩编码系统的一个关键研究课题。 - The problems of CBR ( constant bit rate) traffic in ATM ( Asynchronous Transfer Mode) networks are analyzed, and simple methods to calculate the cell loss ratio ( CLR) and mean cell delay are derived.
分析了ATM网络中CBR业务排队性能，给出了一种简单的计算信元丢失率和信元平均时延的表达式。 - The coding scheme of Constant Bit Rate ( CBR) which is used in most of cooperative transmission project misfits wireless systems, because of the statistics of wireless channel has its temporal spatial variability.
由于无线信道的统计特征随着时间和空间变化，现有的协作通信方案中大多采用的固定码率的编码方案并不适合无线系统。 - For voice service which require constant bit rate, the power adaptation is used. While for data service, the rate adaptation is used, since data service can tolerate some delay.
对于要求恒定比特速率的话音业务，可以采用功率自适应，而对数据业务采用速率自适应，因为数据业务能够容忍一定的时延。 - An analog video was compressed to digital stream with constant bit rate ( 4-8Mbit/ s) using MPEG-2 standard. The stream was transported to decompressed side to recovery the original picture by multiple E1 inverse multiplexing.
该方案中视频图像经过MPEG2标准压缩生成恒定速率（4～8Mbit/s）的数字码流，采用多E1反向复用技术将其传送到视频解码端还原。 - It is possible to setup integrated streams defined perfectly and can be led to pipe with constant bandwidth, if DiffServ authenticates and classifies data streams of constant bit rate using the RSVP parameters or according to the types of special application.
如果DiffServ使用RSVP参数或根据专门应用类型对恒定比特率（CBR）数据流进行鉴别和分类，就可能建立完全定义的综合流，它能够被引导成为固定带宽的管道。 - The result shows that this algorithm is better than that of constant bit rate distribution on the performance of error rate in the addition of reducing the transmission power of system.
结果表明，该算法在误码率性能上明显优于等比特分配算法，也减少了系统的传输功率。 - Adaptive DCT coding of images at a constant bit rate
给定码率的DCT自适应图像编码 - This bit rate can be approximately constant to support constant bit rate traffic or it can be highly variable to support variable bit-rate traffic.
比特率可以近似不变以支持恒定比特率业务或者高度变化以支持可变比特率业务。
