Multimedia
Modalities:
We perceive media in different ways such as listening and reading.
· Tactile – Touch
· Gustatory – Taste
· Visual – Sight
· Auditory – Hearing
· Olfactory – Smell
Channels:
1. Listen to music: Auditory
2. Hear noises: Auditory
3. Receive spoken communication: Auditory
Are they all the same?
No, they are very different yet they all operate within the same modality
This is where the “channel” of communication comes in:
Channels exist within a modality and one modality may contain many channels.
Within our visual modality, there will be different channels for video, graphics and text.
Bandwidth refers to the amount of information that can be carried by a certain channel within a modality.
We can read words from printed text at 100 words per minute
But we can listen to words at 500 words per minute.
This is a comparison of the “printed text” channel in the visual modality and the “spoken text” in the auditory modality.
Bandwidth will also depend on the individual and it’s very unlikely that you would reach maximum levels.
Medium:
Multimedia is delivered through a medium containing more than one channel operating across several modalities.
Television is a prime example where multiple modalities are used (auditory and visual) and multiple channels (text, music, moving picture, spoken words)
What about radio?
Radio is a medium which includes music, spoken word and sounds.
The channels however are all in one modality.
Definition of Multimedia:
Multimedia is a combination of a variety of communication channels delivered through our modalities.
The integration of the following elements:
· Text
· Sound
· Video
· Graphics
· Animation
