Multimedia Hardware and Software


Mm hardware l.jpg
MM hardware

We need to distinguish between hardware requirements for MM production, and hardware requirements for MM delivery


Producing mm l.jpg
Producing MM

  • MM production requires high quality, high speed equipment with massive storage

  • Need to store, and process, vast amounts of MM data such as images, sounds, and video

Producing MM

  • Need to be able to capture video from camera to disc, at a constant rate

  • Need to be able to record sounds using high quality microphones in a sound studio


Mm delivery l.jpg
MM Delivery

  • Computer hardware to be used for running MM products requires particular specifications
