When most people refer to multimedia, they generally mean the combination of two or more continuous media, usually with some user (115) . In practice, the two media are normally audio and video, this is, (116) plus moving (117) .
It should be’ obvious by now that transmitting multimedia material in uncompressed form is completely out of (118) . The only hope is that massive compression is possible. Fortunately, a large body of research over the past few decades has led to many compression techniques and algorithms that make multimedia transmission (119) .
（119）是（）
A.impossible
B.fearful
C.feasible
D.program
E.question
F.ting
参考答案：C
解析：
大多数人谈论多媒体时往往指的是两种或多种连续媒体的组合，通常还融合一些用户的交互。实际上，这两种媒体通常是指音频和视频，也就是声音加上运动着的画面。
现在人们已经知道使用非压缩方式传输多媒体信息是完全不可能的，惟一的手段就是进行大幅度的压缩。幸运的是，过去几十年进行的很多研究已经产生了很多压缩技术和算法，从而使多媒体传送成为可能。
