Can AV terminal be converted into VGA or HDMI square dance audio (DVD player)?

Of course, the price seems high. You'd better go to the store to connect the wires. If not, you can change it at any time. Then the HDMI port needs a dedicated line, which is not available in every machine. 480P is not HD, but it should not be blurred by 15 ". At present, most stereos are USB input, 1080P high-definition images.
