Old-fashioned TVs generally do not have a new type of HDMI interface. The interfaces are some of the older AV interfaces. How can these old TVs become smarter through these AV interfaces? There are two ways
Method 1: TV box with AV interface, such as the mainstream of the day cat box in the market, most models of millet box are equipped with AV interface, with Lynx box as an example, as follows. 
However, under normal circumstances, the TV box is not supporting the AV cable, which requires us to prepare a delay of three AV cables, as follows. 
The AV cable is connected to the TV box one end, and one end is connected to the old TV. After the completion, you can download various kinds of TV software such as sofa butlers in the box, watch popular movies, play video games, and old TV can also be done!
Method two: TV boxes without AV interfaces There are also some boxes on the market. Although they are powerful but they do not have AV interfaces, such as the enhanced version of the Millet Box 3, in the face of such TV boxes, an adapter for HDMI to AV cable is needed. 
One end of the converter is the AV interface, and the other end is the HDMI interface. The AV cable is plugged into the TV and the converter AV interface according to colors. 
Then the HDMI interface of the converter can be connected to the HDMI port of the TV box. After the connection is completed, the basic operation is basically the same as the setting of the connection TV box mentioned above.
