Webcast:
"Webcast" can be roughly divided into two categories. One is to provide TV signals to watch on the Internet, such as live broadcasts of various sports competitions and cultural activities. The principle of this live broadcast is to convert TV (analog) signals into digital signals through collection, input them into computers, and upload them to websites for people to watch in real time, which is equivalent to "Internet TV"; The other is the well-known "webcast": independent signal acquisition equipment (audio+video) is set up on the spot and imported into the pilot, and then uploaded to the server through the network and posted on the website for people to watch.
