Question

电子信息工程专业英语(李白萍)中文翻译

• Windowing. One frame of information overlaps a background frame, and the size of frames can be changed by the user so as to view portions of several frames simultaneously.
• Fast Forward, rewind, pause, and skip. “Tape recorder” commands to control the sequence and speed of presentation of information can be used, not just with audio and video information but also to control a sequence of frames of data, fax, and image.[2]
• Conversational interaction. When a human user is present at each end of the communication channel, a wide range of conversational interactions are possible, including audio discussion, displaying data and images in shared screens, and pointing to, editing and annotating the contents of the shared screen.
Enabling Technologies
Multimedia communications has come about as a result of the development of a number of technological capabilities. These capabilities are described in the following subsections.
• Fast-Packet Networks. The high bandwidth, burst nature of multimedia communications makes it particularly suited to fast-packet telecommunication capabilities such as those provided by ATM and DQDB. Until these networks are widely deployed, multimedia communications can be based on circuit capabilities at a range of bandwidths and lower bandwidth packet capabilities. such as X.25 and frame relay.[3]
• High Capacity Storage Systems. The predominance of storage intensive media, such as audio, video, and high resolution image in multimedia communications requires high capacity storage systems, such as optical disks.

Answer 1

• Windowing. One frame of information overlaps a background frame, and the size of frames can be changed by the user so as to view portions of several frames simultaneously.
窗口。一个消息框重叠着一个背景框，而且用户可以为了同时查看几个框的局部而改变这些框的大小。

• Fast Forward, rewind, pause, and skip. “Tape recorder” commands to control the sequence and speed of presentation of information can be used, not just with audio and video information but also to control a sequence of frames of data, fax, and image.[2]
快进，快退，暂停和跳过。可以使用控制数据输出的序列和速度而且还控制序列的帧数据、传真和图像的“磁带录音机”命令，而不仅仅靠音频、视频信息。

• Conversational interaction. When a human user is present at each end of the communication channel, a wide range of conversational interactions are possible, including audio discussion, displaying data and images in shared screens, and pointing to, editing and annotating the contents of the shared screen.
对话性互动。当个人用户出现在每一个信道终端时，大范围的对话性互动是可能的，包括音频讨论，在共享屏幕上显示数据和影像，并指出，编辑和注释共享屏幕的内容。

Enabling Technologies
Multimedia communications has come about as a result of the development of a number of technological capabilities. These capabilities are described in the following subsections.
促成技术。由于许多科技能力的发展，多媒体通信已经出现。在下面的小节中将描述这些能力。

• Fast-Packet Networks. The high bandwidth, burst nature of multimedia communications makes it particularly suited to fast-packet telecommunication capabilities such as those provided by ATM and DQDB. Until these networks are widely deployed, multimedia communications can be based on circuit capabilities at a range of bandwidths and lower bandwidth packet capabilities. such as X.25 and frame relay.[3]
快速分封网络。高带宽、突发性的多媒体通讯使得它特别适合快速分封的电信能力，比如那些由ATM和DQDB提供的。直到这些网络广泛的展开，多媒体通讯才可以基于一系列带宽的电路能力及更低的带宽组的能力，比如X.25和帧中继。

• High Capacity Storage Systems. The predominance of storage intensive media, such as audio, video, and high resolution image in multimedia communications requires high capacity storage systems, such as optical disks.
大容量存储系统。多媒体通信存储密集媒体比如音频、视频及高分辨率影像的优势，要求大容量存储系统，比如光盘。

结合你的专业，你可以参考一下。

Answer 2

赋能技术
  多媒体通信已来，由于发展了一批技术能力。这些能力是描述在以下各小节。
  
•快速的分组网络。高带宽，水管爆裂的性质，多媒体通信，使特别适合于快速数据包电信的功能，例如所提供的ATM和dqdb
。直到这些网络的广泛部署，多媒体通信可以基于电路的能力，在一系列的带宽和低带宽的数据包的能力。如X.25协议和帧中继。

]
•高容量储存系统。占主导地位的存储密集的媒体，如音频，视频和高分辨率图像在多媒体通信，需要高容量的存储系统，如光盘。
  
•强大的处理能力。该编码/解码的各种媒体，再加上同步他们的介绍给用户，需要强大的处理器。
  
•压缩编码。发展编码技术用于音频，图片和视讯已使多媒体通信被压缩成可用带宽。这使许多多媒体系统加以发展之前，提供宽频网络。宽带通信的结果，在提高质量和较低的端到端延迟。
  
•超文本。超文本是一个多媒体的先驱，这是发展数年前所需的技术，成为多媒体资料。

]只用一中的形象-它提供了许多互动的能力，多媒体系统和服务，以总理的市场，为真正的多媒体这是成为可用的今天。
  
•窗口。视窗软件给出了一个界面，在其中用户可以互动的几个文件或软件过程中使用一个单一的画面。它本来是发达国家在一个单一的中等情况，即图像，并迅速扩展，以配合影片的议案。它大大提高了互动的能力，许多多媒体系统今天业务的优势，多媒体通信
  有一种强烈的潜在需求，为多媒体通信作为证明：
  
•使用视频显示技术制图或其他物件的讨论，以及头部，肩部的讨论。这基本上是使用的议案，视频提供一个仍然形象的能力。
  
•使用传真和数据通信设备的过程中视频;
  
•使用调制解调器，让语音和数据通信超过一个声音高档路线。
这些例子意味着需求的互动组合，所有五个传播媒体：音频，数据，图像，传真和视频。
  业务的成效，多媒体通信，可以预计从较早前的成效形式的计算机介导的通讯（管委会）在用户进行数据交换，有时作为一个伴随了电话交谈。业务的经验，中央军委和研究它的好处，更是建立了较多媒体以来，已用它自1970年代中期以来。的成效，中央军委已分析了企业集团的决策情况，在教育环境作为教学工具
