Video Formats and Bandwidth

Video formats are not just defined by the number of pixels on the screen. This section gives you some clues to
understand the language video people use.

As usual in electronic signals, the bandwidth is the value determining the amount of transmitted information per
second.

In both analog and digital worlds, this value is critical.

A high definition color picture is more bandwidth demanding than a standard definition one.
