Summary

A Samsung SmartTV application runs on a browser environment that is similar to PC-based web browsers, and can use most of the standard web development techniques. Chapter 6 will introduce and carefully review a scenes-based programming method that uses different scenes to efficiently handle key events. This method accommodates characteristics of a TV application that uses remote controller-generated KeyDown events.

The Samsung SmartTV SDK provides the Scene Manager to quickly and easily develop an application screen. However, in this chapter, we will not use the Scene Manager; instead, we will manually implement a simple TV app screen. This will help us to understand how a SmartTV application handles possible exceptions.

This chapter's scene creation / switch method is not the ultimate right answer. Different situations require different solutions. Please consider the next method as a tutorial that will help you understand the structure of a Samsung SmartTV application.

As explained earlier, a Samsung SmartTV application consists of HTML, CSS, and JavaScript files, as does a web application. Therefore, we can use styles and HTML elements, as is commonly done in web development.
