Now most set-top boxes have AV interfaces, which can be used to connect TV.
1. Connect the set-top box.
One end of the AV cable is connected, and the corresponding color is inserted into the set-top box interface. Some set-top boxes have only one hole in the AV cable, and only one end is inserted into the set-top box.
2. Connect the TV.
At the other end of the AV line, the corresponding color is inserted into the group marked or input on the TV.
