Question

电子信息工程专业英语(李白萍)中文翻译

• Powerful Processing Capability. The encoding/decoding of a variety of media plus the synchronization of their presentation to the user require powerful processors.
• Compression Coding. The development of coding techniques for audio, image, and video has enabled multimedia communications to be compressed into available bandwidth. This enabled many multimedia systems to be developed before the availability of broadband networks. Broadband communications results in improved quality and lower end-to-end delay.
• Hypertext. Hypertext is a precursor to multimedia that was developed several years before the technology necessary for multimedia became available.[4] Using only one medium—image—it provided many of the interactive capabilities of multimedia systems and served to prime the market for the true multimedia that is becoming available today.
• Windowing. Windowing software gives an interface in which the user can interact with several files or software processes using a single screen. It was originally developed in a single medium situation—namely, image—and was rapidly extended to cater for motion video. It greatly enhances the interactive capabilities of many multimedia systems today.
Business Advantages of Multimedia Communications
There is a strong latent demand for multimedia communications as evidenced by:
• the use of videoconferencing to display a technical drawing or other object of discussion as well as the head and shoulders of the discussant. This is essentially the use of motion video to provide a still-image capability.
• the use of fax and data communication equipment during the course of a videoconferencing;
• the use of modems that allow voice and data communications over one voice-grade line.
These examples imply a demand for interactive combinations of all five communications media: audio, data, image, fax, and video.
The business effectiveness of multimedia communications can be estimated from the effectiveness of earlier forms of computer mediated communications (CMC) in which users exchange data, sometimes as an accompaniment to a telephone conversation. Business experience of CMC, and research into its benefits, is more established than for multimedia since it has been used since the mid-1970s. The effectiveness of CMC has been analyzed in business group decision-making situations and in educational settings as an instructional tool

Answer 1

• Powerful Processing Capability. The encoding/decoding of a variety of media plus the synchronization of their presentation to the user require powerful processors.
强大的处理能力。多种媒体的编码/译码加上用户演示的同步，要求强大的处理器。

• Compression Coding. The development of coding techniques for audio, image, and video has enabled multimedia communications to be compressed into available bandwidth. This enabled many multimedia systems to be developed before the availability of broadband networks. Broadband communications results in improved quality and lower end-to-end delay.
压缩编码。音频、图像和视频的编码技术的发展，使得多媒体通信能压缩成可用带宽。这使得许多多媒体系统开发先于可用的宽带网络。宽带通信导致提高质量及端对端延迟。

• Hypertext. Hypertext is a precursor to multimedia that was developed several years before the technology necessary for multimedia became available.[4] Using only one medium—image—it provided many of the interactive capabilities of multimedia systems and served to prime the market for the true multimedia that is becoming available today.
超文本。超文本是多媒体的先驱，它的开发比使多媒体成为可用的必要技术早几年。仅使用单一的媒体----图像----它提供了多媒体系统许多的交互式能力并应用于当今已经可用的提供给市场的真多媒体。

• Windowing. Windowing software gives an interface in which the user can interact with several files or software processes using a single screen. It was originally developed in a single medium situation—namely, image—and was rapidly extended to cater for motion video. It greatly enhances the interactive capabilities of many multimedia systems today.
窗口。窗口软件提供了一个界面，在界面里用户可以使用单一屏幕来相互作用几个文件或软件进程。它最初是在单一媒体环境开发的----也就是，图像----并快速延伸到服务动态视频。这很大的提高了当今许多多媒体系统的交互式能力。

多媒体通信的商业利益
对多媒体通信有一个很强的潜在需求，证据是：

• the use of videoconferencing to display a technical drawing or other object of discussion as well as the head and shoulders of the discussant. This is essentially the use of motion video to provide a still-image capability.
使用视频会议展示技术图或其他讨论的物件以及讨论者的头和肩膀。这基本上是使用动态视频来提供静止图像的能力。

• the use of fax and data communication equipment during the course of a videoconferencing;
视频会议期间使用传真和数据通信设备。
• the use of modems that allow voice and data communications over one voice-grade line.
使用调制解调器使得声音和数据通信能通过一条音频级线路来进行。

These examples imply a demand for interactive combinations of all five communications media: audio, data, image, fax, and video.

这些例子蕴含对所有五种通信媒体：音频、数据、图像、传真及视频交互组合的要求。多媒体通信的商业影响可以从用户用来交换数据的早期的计算机媒介通信形式的效能来评估，CMC有时也作为电话会谈的附属品。计算机媒介通信的商业历程及其益处的研究，自70年代中期它开始应用以来就比对多媒体多。计算机媒介通信的效能被研究于集团企业决策的环境及教育设置中作为教学工具。
