积累式压缩与传输算法在B超视频远程实时传输中的应用
The Applicatkon of Accumulating Compress and Transmit Arithmetic to the Remote Real-time Transmission of B-ultrasonic Images
【摘要】 为了在低带宽信道中实时地传输B超视频图像 ,本文提出了积累式压缩与传输算法。该算法把图像的压缩、传输和机器的处理性能有效地结合起来 ,其编码器仅对视频中高层次信息进行编码 ,最终输出的信息量不但能够刻画视频中的主要变化信息 ,而且不会超出CPU的处理能力 ,同时也不会超过传输信道的承受能力。最终 ,该算法能够充分利用信道的带宽和机器的处理能力 ,即使在较低速率通讯线路上 ,仍能够实现B超视频的实时传输
【Abstract】 In order to transmit real time B ultrasonic video through low bandwidth channel, this paper presents accumulating compress & transmit arithmetic. This arithmetic effectively integrates these three elements: Compression of Video, Transmission of Video and The Capacity of CPU. Its coder only codes high level information which describes primary changing between frames, so the amount of coded data will full into the capacity of computer and channel. In a word, this arithmetic can make full use of the ability of machine and channel, so it will transmit real time B ultrasonic video even through rather low rate channel.
【Key words】 B ultrasonic video; accumulating; leveled information; changing sensitivity; base image;
