Microsoft Teams will be based on the pre-conference, meeting, after the formation of the full life cycle of conferencing solutions, understandable Teams cloud collaboration in the field of video conferencing has been in a leadership position, coupled with the recent video Teams constantly optimize bandwidth less and less while the MTR (Microsoft Teams rooms) devices blessing it is able to solve a variety of video conferencing from the desktop to the conference room level. Before we have been using the international version of Skype for business Online meeting say the effect is not too good to be honest, open Zoom back into the weekly regular meeting, but due to the recent well-known reasons Zoom become a less reliable. So we try to switch to open Teams weekly meetings, it will post feedback effect even better than the Zoom point.
Teams then broadcast (also known some people live) What is this? In Skype for Business also has a radio , and a Skype for Business Teams upgrade products. However Teams broadcast and Skype for Business broadcasting have fundamentally different, Skype for Business broadcasting is based broadcast realization, Teams broadcasting is based on Stream achieve and Stream itself is a video library can be live online, and even configure the codec with green screen technology allows you to live on Mars. The broadcast itself is only a one-way behavior was not destined to be so much of delivery.
Teams I did a long time before the broadcast of the program can simply share with you below:
Combined with simple topology can be seen above:
Teams meeting: completely open collaborative meetings
Teams broadcast: from the organizers, support people, intermediate services, and ultimately the viewer is progressively push
The main difference between the two:
Long meeting: Teams Conference unlimited, Teams broadcast an event up to 4 hours;
Delivery of assistance: Teams conference collaborate to deliver a complete and through the access control list, Teams broadcast only one-way viewing;
Conference Record: Teams meeting demand manually click Record, Teams broadcast by policies to control whether automatic recording;
The number of restrictions: Teams meetings up to 250 users (including guest users), Teams broadcast up to 10,000 users (including guest users)
质量控制：Teams会议自适应带宽修改分辨率，Teams广播可自适应也可手动设定分辨率；
质量控制：Teams会议最多同时并发250组会议，Teams广播最多同时并发15个广播；
以上是Teams广播和Teams会议最主要的区别，还有很多细小的功能区别有待各位去发现哦。
Teams广播和Skype for Business广播的区别就比较大了，可以参考微软官方文档：
那么需要怎么去开启Teams广播以及需要注意的事项有哪些，下面继续跟各位分享：
需要进行Teams广播首先需要满足以下条件：

Teams广播的网络要求可以参照 Teams会议 列出来的进行准备，关于策略设置可以在Teams管理中心通过UI设置
策略配置好后按需分配给相应的用户
配置好各种策略之后就可以安排Teams广播了，目前只能在Teams客户端中安排Teams的广播，如果是其他广播可以在Stream或Yammer中进行安排。
打开Teams客户端选择日历，点击新建会议，然后点击下拉框选择新实时事件
由于翻译问题，制作者实际就是广播的主持人和演示者，我这里添加了一个MTR账号默认只能是演示者
如果再次邀请其他普通user则可选择是制作者还是演示者
点击下一页配置本次Teams广播的权限，哪些人可以观看
然后最新功能来了：
字幕以及翻译，翻译目标语言最多可以选择6种
问答功能，参与者可以IM提问了
一切配置好之后点击安排即可
MTR设备上同步显示
MTR和我的Teams Client同时进入广播，MTR中已经启用并共享虚拟现实白板，选择后点击实时发送，并点击开始，所有在本次广播事件中的用户都能看到虚拟现实白板，同时在右侧有心跳符号和问号，分别是Teams广播的网络监控（每15秒刷新一次数据）关于网络中媒体比特率限制可参考我这篇文章的配置，以及参与者题问的问答界面
Even after the video images and share content (you can also choose to share the host desktop, applications, etc.) are combined in real time sent to all broadcast viewers
On the MTR see the effect as follows:
Teams from throughout the broadcast because it is the host presenter to share data and video streaming viewer push down, so there will be a delay of about 10 minutes this is a normal phenomenon.
Special attention, after Team broadcast once opened can not be turned back on again if required broadcast'll need to reschedule the broadcast event.
Therefore Teams broadcast preaching style is more suitable for the General Assembly or the year-end conferencing network teaching (with MTR and whiteboard use with virtual reality), Teams meeting is more suitable for the delivery of collaborative communication session. Small partners you can try Teams broadcast Oh.
