IPT: Processing Multimedia

In a classwork post...
Recall that processing involves an actual change in the data. With respect to multimedia, processing usually takes place for one (or both) of two reasons:
  1. Hardware limitations. Dithering and data compression are both kinds of processing that exist sheerly because of limitations in the computer-based hardware systems we use. Describe the nature of these limitations (firstly for dithering, secondly for data compression) with respect to the relevant information processes, and explain how these kinds of processing compensate for these limitations. (Pages 298-300 in the textbook will assist you.)
  2. Creative purposes. Photo and video editing (e.g. composing scenes in a movie, adding visual or audio special effects) can be applied to multimedia simply for creative reasons. Identify ten examples of these. (Hint: any major sci-fi or fantasy film at the movies will include hundreds of these - but think of some broader examples please!)
After you have answered the questions above, read pages 297-302 and answer the questions on page 302. These questions include some material on transmitting and receiving as well as displaying, though these are not the focus.

Lastly: with your remaining time, devote your attention to Component 3B of your multimedia assignment. By the end of this double, you should have at least selected the subjects of your case study and updated your Gantt chart to include the development of the multimedia system.
 
Once this is done, post a summary of what you have done (and any further progress you make on the mini-assignment) on your project register. It's vital that you use this double period effectively - please don't waste any time this lesson!
