Viewing information consultation live broadcast.

Take a chestnut, live broadcast is what others are doing, you see, what you see is what others are doing now. On-demand means that others first record what they do with things and then put them online. You click and watch through the internet, which lacks real-time performance. Video conferencing means that the other party is equal to you. Others can see what you are doing, and you can also see what the other person is doing. You can communicate in real time, similar to Huawei video conference, and you can also enjoy files in real time. If you still don't understand, you can continue to consult me.
