THE ESSENCE OF (VIDEO) COMPRESSION
From my presentation: "How bad is good enough!?"
It is practically a cliche these days to claim that all electronic communications is engaged in a digital revolution. Some communications media such as the telegraph and telegrams were always digital. However, almost all other electronic communications started and flourished as analog forms.
Digital audio and video signals integrated with computers, telecommunication networks, and consumer products are poised to fuel the information revolution. At the heart of this revolution is the digital compression of audio and video signals. Let's first introduce the concept of compression.
Case One: Powdered Milk
A spoon of a powdered milk mixed with a cup of boiled water will produce a cup of milk. A bowl of hot water mixed with a few spoons of powdered milk would produce a bowl of milk. This "technology" was used in my village after World War II; Red Cross supplied cans of powdered milk, we supplied the hot water.
This process could be considered as a "milk decompression". The opposite process - "milk compression", would reduce a tank of milk into a bag of milk powder.
Case Two: "Honey I Compressed Myself"
