If you have an old smart TV in your house, then you will see red, yellow, green and blue buttons along with other buttons on its remote. Some set-top boxes also have such buttons on their remotes. Many times nothing happens when you press them, but if they are given on the remote then they must have some purpose. Let us tell you that these buttons are context-shortcut sensitive, about which most people are not aware. Today we will tell what is the function of these colorful buttons on the remote.
Started before the advent of internet
Giving red, yellow, green and blue buttons on the remote started before the Internet. Actually, these buttons were started for teletext. Before the advent of the Internet, it was an information service in Europe and the UK. In this, colour-coded links were shown at the bottom of the screen. By pressing the button of the color of which the link was there, the user could click on those links, which would take him to the page related to weather or news etc. Now this service has been stopped, but TV companies have not stopped providing these buttons and now they are being used for navigation.
Now what is their use on TV remote?
Even today, these colorful buttons are seen on the TV remotes of many companies. These work as shortcuts or hot keys. That means some function is added to these buttons. In such a situation, as soon as you press this button, that function will open. Many companies also provide the option to customize these buttons, where users can customize them as per their wish.
What is their function on set-top box?
Like TV, these buttons on set-top boxes have also been assigned special functions. These can be used to change language settings, subscribe to paid services and open other menus. Many companies also offer the option of video recording through them.
