Some NBA games are televised, so is the commentator's explanation live or afterwards?

If it is a live broadcast, it is to buy the game signal from the United States (usually provided by major American TV stations TNT, FSN, ESPN and ABC), and then send it to the TV station in China via satellite, and then the commentator of China TV station will explain it on the spot. If the game is over and recorded by China TV (sometimes recorded by CCTV5), then their explanation will not be recorded, but they know the result of the game.

SMS is an activity that TV stations in China are engaged in explaining and interacting with viewers. It is charged on a monthly basis (for example, CCTV5 has a monthly subscription in 8 yuan). During the broadcast of the game, you can send short messages, and then you can see all the short messages on the short message interactive platform of the TV station. However, because there were many people who sent short messages in the past, the refreshing speed was fast, and the short messages that could be understood by them needed a certain language level and a little luck.
