关键区别 - 网络研讨会与网络广播
尽管两个术语网络研讨会和网络广播是指类似的通信媒体,但根据其目的和受众群体,它们之间存在明显的区别。这关键区别between a webinar and a webcast is that网络研讨会促进了较小的小组之间的双向通信,而网络广播则促进了较大组之间的单向通信。Whatever the difference, many benefits can be obtained by conducting both, webinars and webcasts. Targeting a specific audience which is relevant to the discussed topic is one such benefit. A large audience can be supported with the use of internet technology. The user can participate immediately in the conference without needing to schedule it. The other important factor is the low cost that is involved with Webinars and Webcasts. Traveling to the specific location is not needed and setting up costs is reduced dramatically. High tech interaction means a better experience for participants and promotion of forward thinking. Let us discuss them in more detail here, before going into the differences between both, the webinar and webcast.
什么是网络研讨会?
网络研讨会可以定义为aconference这是以A的形式实时进行的seminarwith the use of the internet。网络研讨会的优势在于,无论其地理位置如何,任何人都可以参加会议。这是一个很棒的功能,因为它允许参与者参加会议,即使他们相距许多英里。网络研讨会能够借助voip和视频流允许参与者和演示者进行有效沟通。他们还能够实时讨论主题。
网络研讨会的最常见用途包括会议,会议,培训计划和研讨会。网络研讨会也可以在以后进行录制和观看,但是实时元素将丢失。录制的网络研讨会可以成为网络广播。网络研讨会使用TCP/IP。有时需要下载软件才能参加网络研讨会。活动接口将通过电子邮件和日历提供,并且可以通过其他方法提供协作以准备网络研讨会。可以托管网络研讨会事件以供匿名参与,也可以通过代码或ID识别主机。在这两种情况下,参与者的身份始终得到保护。
这re are some other features that are supported by Webinars. The presenter’s computer screen could be shared among all users who are participating in the Webinar. There are even options when the audience gets a chance to control the presenters screen as well. The Webinars also support polling among the audience with the use of multiple choice questions. The vendor hosting the event may charge per minute, monthly subscription, or a rate according to the amount of participants in a Webinar. The vendors associated with Webinars include Microsoft Office Live Meeting, Open meetings, Skype, Web Train, etc. Webinars can be a hosting service, an appliance or a software.
什么是Webcast?
Webcast can be defined asa broadcasting or presentation with the use of the internet。With the development of technology, the internet is able to offer great data rates. At the same time, digital audio and video technologies have evolved paving the way for businesses to make use of Webcasting rather than other presentation techniques. The vendors use different kinds of Webcasting for different occasions. One method of Webcasting involves broadcasting pre-recorded, pre-arranged media across the internet. The users can view these media on demand. There is also real-time webcasting. For example, lecturers can present the information over the internet as a Webcast, and the audio and videos of the events can be presented over the Internet in real-time. There are other kinds of Webcasting likePowerPoint演示文稿, which is accompanied by the real-time audio of the presenter over the internet.
Live streamingis also a process where information is delivered straight to the computer without it being saved on a disk or hard drive. Real-time Webcasting is pretty much what is mentioned by live streaming. If we take a closer look at how live streaming occurs, the audio and video is captured using a video camera and is transferred to a software on the host computer. After the captured information is compressed and digitized it is sent to aCDN(内容输送网络服务器)。This sever is responsible for distributing the encoded information over the internet. This could be done in the form of a broadcast or as on demand that could be viewed at a later time. There are programs like real player which decode the stream sent from the CDN server and then webcast could be viewed. These types of streams are usually compressed to reduce the size so that the information can be streaming quickly and retrieved in real time. For compressing the videos, there are many compression technologies available in the market (Ex:MPEG-4)。这是网络广播的示例。

作为我们的结论,与网络研讨会有关的合作少,但是与其使用共享的信息更多。通常,它涉及一个或多个演示者,并遵循演示风格的重点。它比网络广播更具吸引力,并且是教学和学习的好工具。有民意调查和问答,以使其进行双向交流。
当我们考虑网络广播时,它是单向通信,主要使用音频和视频,并同时针对更大的受众。可以实时查看网络广播,也可以记录下来,以便用户在以后查看内容的便利。
两者都是出色的在线工具,可以使生活更轻松,而不是参与者。这些基于网络的技术的增长速度更快,因为许多公司都将其用作具有成本效益和更大范围的营销工具,而不是传统的广告平台。
