Problems solved by technology
[0002] At present, when TV manufacturers test TVs (especially LED (light-emitting diode) TVs) on the production line, they use HDMI signal source detection for HDMI (High Definition Multimedia Interface, high-definition multimedia interface) function tests. , so there is a problem: HDMI is very slow from converting the channel number to identifying the signal (usually more than 5 seconds)
Today's TV sets basically have more than two HDMI interfaces, so the manufacturing efficiency is very low
Moreover, there is no good and quick way to detect the special functions of HDMI, such as CEC (Consumer Electronics Control)\HPD (Hot Plug Detection)\HDCPKEY (product key), which have become the whole process of TV production. bottleneck process
