The rise of digital television

What exactly is digital television, and why is it still better than traditional analog television? The difference has to do with the bits of information that are set by the digital video signals. Digital signals are sent in tiny little pieces of, called digital data. If you were to see this data written now, it would look like a series of ones and zeros.

The signals provide crisp and clear transmissions because the data is transmitted in exactly the same way every time. This means you'll get the same quality picture every time you watch TV using digital signals. In general, digital signals can also carry much more information and detail than analog signals can.
