In my research about the Smart TV,
Smart TV's browser is made up Webkit core.
The TV can support almost HTML5 specification.
You need to want to read a more specification below:

Actually TV dose not use a good hardware.
According to people who is developing a TV contents,
the CPU is 1GHz dual core, RAM is about 800Mbytes?
Anyway..
Is the C2 audio made up the Audio tag of HTML5?
