OUTPUT DEVICES - Video Devices
- There are a wide variety of video cards available which support various sizes of video within a window. Other facilities provided are:
OUTPUT DEVICES - Projectors
- There are three general ways to project the image from the computer
- CRT projectors are the longest established. They can take some time to set up as they use three separate projection tubes for different color channels and they must coverage accurately on the screen to get a sharp image.
- LCD panels are used with an overhead projector which supplies the light source. The image appears on the panel which is connected to the computer.
- LCD projectors are the third option. These are becoming increasingly popular. Although quite heavy they can be carried around and contain their own light source. They are also much easier to focus than the CRT projectors.
- Multimedia is very demanding on computer memory.
- In addition to storing the program code, memory is needed to handle the images, sound and video clips.
- The actual requirements will depend on the contents and media.
- Developing a multimedia at least doubles the requirement as it is sensible to have at least one back of all the content that has need produced.
MEMORY and STORAGE - RAM- inadequate RAM (Random Access Memory) will slow down the delivery and the development of multimedia applications.
- Many of the Multimedia authoring tools have high RAM requirements although MPC 3 standard is 8mb, 16mb or 20mb is preferred.
- 32mb or 64mb is not uncommon on the Macintosh platform for development machines, particularly if a number of applications need to be opened at the same time
