You may already be familiar with Smart TV -applications, but have you ever wondered where they come from? Probably not, and that’s why I’ll tell you how the apps you use are made and how they appear on your TV screen. My goal here is that after reading this article you shall have some idea of what Smart- TV development is and what tools it takes for you to implement your own application. As an example, I use Vestel MB230 2020 –Smart TV, which is sold in Finland as Finlux, for two reasons:
- It’s an affordable way to get started
- It is a flexible platform to start with
There are also other platforms to start application development. If you choose some other platform the basic coding principles are the same but at least the software development kit (SDK) is different.
Let’s get started now!
First, you need a web server, local or online, the place where the Smart TV can connect to. Let’s say it’s www.sofiadigital.com/my-awesome-smart-tv-app. Then you need index.html-, styles.css- and app.js-files, and maybe also images-folder. Index.html doesn’t contain anything fancy, just basic html-elements, and may look like this
The app-element is the place where the magic happens. “Hello Awesome App!” text is there only to show that our application starts. App.js contains all the code base and styles.css has all the styling. I recommend that you add a little bit CSS here because default body background color is black
Awesome! Now we have a base template for our Smart TV –application.
Then, how can we test this in our Smart-TV? First, you need a memory stick. Create starturl.txt-file to the root of the memory stick. Open the text file, write the apps web address there and save the file. After that put the memory stick to the Smart TV’s USB port, press MENU and use the remote control to press keys at this order 4-7-2-5. A “secret menu” appears and select USB Operations from the menu. Wait a moment and then go back to the main menu and you should see a Custom App –icon in Apps-menu.
Now our app starts when you select the Custom App and it should look like this.
Now I’ve shown you how to get started in a Smart TV -app development on one platform. There are several other platforms, like Tizen, WebOS and Android and every platform has its own pros and cons. This is a topic we have covered in another article.
Now you’re ready to start design your own software!
