While choosing to buy a television or already own a television at home, have you ever wondered why behind the TV, right at the connection port, there are so many different symbols? What does it mean? What is it used for? The following article will help you decode the symbols about the connection ports on HDMI and USB TV.
The USB slot with this symbol means you can plug in an external camera purchased from the company for smart interactions or video chats through the Skype app.
Many people still complain that, why their USB ports can only read data from the USB but not the HDD? The answer is extremely simple because their USB port does not support HDD.
When buying a television, if you plan to watch movies from your hard drive, you should choose a model with a USB port symbol of 5V 1.0A (TVs with this symbol allow to read USB and hard drive). TV models have a USB port symbol 5V 0.5A, it can only read USB.
When using TV models that have the HDMI port symbol included with ARC, it means that you have in hand a television that is capable of producing sound response with only HDMI cable.
Simply put, it is easier to understand that if the TV has HDMI ARC port, there will be Audio Return Channel function to reverse the signal from the audio from the TV to the outside through the HDMI port (When watching movies with the player (DVD / VDC)) will be able to transfer the audio signal from the player to the TV, when watching cable TV, there is the ability to transfer the sound from the TV to the speaker). However, ARC is only available when the TV is connected to a transceiver that supports ARC.

When the TV that you see appears the symbol of STB right at the HDMI port means that you can watch cable or satellite TV through the set top box or CableCARD converter. Thanks to the HDMI STB port, the cable TV quality will reach the perfect standard of HDTV range (the HDTV standard must register with the cable TV network).
So, if on the same TV when pairing the set top box, you should pay attention to pair the correct HDMI port with STB symbol because it will bring better picture quality (other ports may not be used).
HDMI MHL is meant to allow pairing to another peripheral device ( smart phone or tablet ) that supports MHL. This makes it easy to transfer images from your external device to the big screen of your TV.
