Design - Density of Information

There are  two kinds of density of information that is one with rich in information and the second is 
minimal information. 

The first ident is used for channel 4. This is rich in information because you have a lot going on as you have some sort of narrative happening. You have the canal going past and a man painting, on top of that you have a voiceover on what is coming up on the channel. This interval would be used for the crew of the channel to be ready to broadcast the next programme.

The second ident is used for BBC One. This is minimal information because they have a lot of people on bicycles going around in a circle with no voiceover or anything going on. This could be used as an interval for people in the studio getting ready for the BBC News.
