In addition, video and audio feeds are extremely costly to store due to the large volumes of this type of data collected, coupled with its poorcompression characteristics.
此外，视频和音频记录的存储成本非常高，因为此类数据的量很大并且不能有效地压缩其体积。

Increase the compression degree can make arc of high temperature plasma jet extended, form more uniform high temperature area, and increase the speed of the jet, can reduce the width of the poor.
The on-the-wire encoding of CORBA contains a large amount of redundancy, but the protocol does not support compression. This leads to poor performance over wide-area networks.
