質問したらlineに　中国語で　回答が届いていた。

Google で翻訳して、そのように操作してみた。

とりあえずは　映るようになった。

( ただし　NHKは、GもEもBSも全て映らない。)

でも　チャンネルチェンジって繰り返してやると　コードが無効になる　って　？？？、どうすればいいのか。

Step 1: Please restart the playback device after one-click acceleration on the main interface (or reinstall it, it must be done. Or restart the box)

Second. Re-open uPlive live broadcast,

Third, in the login interface of UPlive, select the box and press the OK key, and the keyboard will pop up. Enter the verification code I sent the verification code

(Notes:

 1. When the verification code user does not use the UB software, please exit the APP or shut down, and do not allow UB to repeatedly acquire data in the background.   ???

2. When watching the program, please do not keep pressing the channel change up and down buttons to change the channel repeatedly. Otherwise the verification code will be invalid). ????

Do not understand Chinese, please translate by yourself

Due to compatibility issues: old machines do not support UPTV, please use UPlive

以上　(8/4 記)
