Embodied by products called codecs (compression/decompression),these methods fall into two general categories: interframe and intraframe compression.Interframe compression uses a system of key and delta frames to eliminate redundant information between frames. Key frames store an entire frame, while delta, or “difference”, frames record only the interframe changes. During decompression, the CPU builds frames from the key frames and accumulated deltas.Intraframe compression is performed entirely within individual frames. During intraframe compression, codes use a variety of techniques to convert pixels to more compact mathematical formulas. The simplest technique is called run length encoding (RLE), in which rows of adjacent identical pixels are grouped together.视频图像压缩是一组用来缩小视频图像文件大小的技术. 由被称为Codecs(压缩/解压)产品所体现的这些方法分为两大类: 帧间压缩和帧内压缩.帧间压缩利用关键帧和§帧方法来消除帧之间的冗余信息. 关键帧存储一幅完整的帧, 而§帧或”差异”帧, 仅记录帧间变化. 解压时, CPU从关键帧和累加的§帧来构造各个帧.帧内压缩是完全在个别的帧内进行的. 在帧内压缩时, Codecs使用各种技术把像素转换成更紧凑的数学公式. 最简单的技术称作行程长度编码(RLE). 按这种编码法, 各行中相邻的相同像素串归在一起.2.Data communications systems are the electronic systems that transmit data over communications lines from one location to another. You might use data communications through your microcomputer to send information to a friend using another computer. You might work for an organization whose computer system is spread throughout a building, or even throughout the country or world. That is, all the parts-input and output units, processor, and storage devices-are in different places and linked by communications.……………………你有可能在为一家公司工作，其计算机系统遍布一座大楼，或者甚至是全国乃至世界。
