If you have an existing digital television at home, you should google online to check whether your model had an internal tuner. Most Smart TV version will has an internal tuner so there is no need for you to purchase any external TV tuner.
Use your Smart Phone and take a photo on the back of your TV where they stick the model information.
From my Smart Phone, I type in my Samsung Smart TV model into the google search engine and the result will show me how to do the digital tv tuning to broadcast the MediaCorp free 7 TV channels.
