If you have an old TV at home, which you do not want to part with, with a little effort and low budget you can turn it into a smart TV that connects to the internet.
You don't have to be a hipster to watch Netflix movies on a TV from 1978. It's just an interesting thing that can be done easily, relatively cheaply, and with very little effort.
For this, of course, we use Chromecast, the small streaming stick from Google which, using an HDMI connection, turns any TV it connects to into a smart TV.
The problem is that TVs 30 to 40 years ago didn't even dream of digital connections, which means finding a way to connect an HDMI output device, such as a Chromecast, to a TV that used a receiving antenna.
Three devices are used for this purpose:
1. HDMI adapter - composite
2. RF modulator that converts the composite signal into radio the frequency recognized by old TVs
3. VHF connector (if the TV does not include one) that connects the coaxial cable to the TV's reception system
The order of the connections is as follows: Chromecast - HDMI-composite adapter - RF modulator - VHF connector (if applicable) - TV.
With Chromecast set up and connected to a wireless network, your connected TV will be able to stream everything that is transmitted to you via your smartphone or tablet, including YouTube, Netflix, or HBO Go.
