Generally, smart TVs have their own operating systems. If you want to start from scratch, you have to write the operating system yourself. This involves choosing the underlying hardware and then programming the hardware interface. Understand, for example, microcontrollers. Of course, smart TVs cannot be made using microcontrollers. They must have their own smart chips. The knowledge involved is too complicated and it is impossible for you to do it by yourself from beginning to end. It is just like producing a car. It is not necessary. It's like leaving it to you to make rubber, right? If you want to understand this layer, you need to look at some microcontroller programming and operating system programming to realize the operation of the underlying hardware. C language is the most used in this field. Otherwise, just skip this stage.
The so-called smart TV is actually a TV + computer. It's just that the computer has been miniaturized and integrated into the panel behind the TV display.
In the final analysis, the software development of smart TVs is actually the development software for the operating systems of smart TVs. The more popular operating systems at this stage are Android, and the most commonly used programming environment is similar to JAVA, and smart The TV can run related software as long as it allows the JAVA operating environment or the like. JAVA is also a high-level language based on C, but you don't need to understand how JAVA works. You only need to master the functions that JAVA provides you. This is the advantage of high-level languages.
So the software development for smart TVs is actually no different from the development of general software. However, the expansion capabilities of current smart TVs are still relatively weak. For example, they do not allow the installation of third-party software, just like mobile phones in the early days were all non-smart phones. Now all mobile phones support Java to install the programs you need. In the next step, smart TVs will compress this process. Cloud computing will be widely used in TV applications. Network support will greatly reduce the computing cost of TVs. TVs are only used as a display terminal. To put it bluntly, in the future, whether it is a smart TV or Smartphones will be integrated into one thing by the network. Mobile phones and TVs are only used as input and output terminals, and all calculations are performed on the server side of the network. Mastering the Internet is the most basic and ultimate thing.
