I want to know which brand of your TV, because different brands have different solutions. If you use the set-top box of Puqing TV, you can learn about the local upgrade, because we have Puqing TV that can reach high definition through handling. There is also a universal interface at the back of the digital all-in-one machine. You need to know the instructions of your TV first. Because of the all-in-one machine, yours uses a card, so it is different in chip processing. There are many channels to receive TV signals, and your model and brand are not clear, so it is difficult to answer directly.
