8. MULTIMEDIA HARDWARE  Remember, multimedia takes up a LOT of space.  It also takes a lot of memory and processing power to display and use multimedia on a computer – which can slow a computer down!

9. SCREENS  Screen size – Different sizes and uses (TV, Monitor, Screens etc.).  Screen Resolution – Measured in pixels per cm – governs the quality. The more pixels the better the quality.  TFT (Thin Film Transistor) & LCD (Liquid Crystal Display) – Light, cheap and do not take up a lot of space.  Plasma – can be larger than LCD screens.  (Don’t forget we now have LED screens, 3D, HD and Ultra High-Def)

10. INPUT DEVICES  WHY are each of these needed and what do they do?  Microphone  Graphics Tablet  Mouse  Touch Screen

11. SOUND DEVICES  MIDI devices (Musical Instrument Digital Interface) A go between musical devices and a computer. Converts signals from a device (e.g. keyboard) into something the computer can understand.

12. DIGITAL CAMERAS AND DV CAMS

13. MEGAPIXELS EXPLAINED  The number of pixels in the image.  The higher the DPI the closer the pixels are together.  MP governs the SIZE more than he quality.

14. CAMERA TECHNOLOGIES Digital CamerasDigital Video Cameras  All stored digitally – no developing.  A range of effects (red eye, steady shot, face recognition, geo-tagging, B&W, mosaic etc.)  High optical zoom  Can support HD, 3D and Video  Direct posting to social networks  Available in very high MP  Can be stored digitally (DVD, SD etc.) or on tape.  Can shoot in HD, 3D  Can stream online  Range of effects  Can take pictures as well as video.  High MP for shooting video  LCD Preview screen.

15. BUT WHAT ABOUT WEB CAMS?  Good enough for using online.  Can take simple pictures – limited effects.  Low quality MP – but good enough for online.  Used for instant messaging, remote meetings, video conferencing etc.  Often built in to computers (laptops and Apples)

16. INTERACTIVE COMPONENTS Keyword Searches Links Why are they used?

17. QUIZZES  Combines lots of different multimedia: video, sound, text and images  Can be created online and in software such as PowerPoint or Flash.  Can be used to check learning, gain feedback or just for fun!  Where would quizzes be used?

18. QUESTIONNAIRES  These can be used in a range of places to obtain feedback from a range of people.

19. GAMING  Games use a massive array of multimedia.  Intense sound, graphics and text are used with a lot of interaction with the user.  Requires specialist, hi-spec hardware to cope with the level of graphics and processing speed.

20. WHAT IS GOOD AND BAD ABOUT EACH METHOD? MultimediaHow can it be stored (where does it come from) Text Typed into a word processing document. Found online in web pages Sound Capture yourself in recording software Mix yourself Online libraries CD’s etc.. Can be linked or embedded into multimedia – GOOD or BAD? Graphics Scan in from different places: books, magazines etc. Find online Capture yourself Clip-Art Draw them yourself in graphics software Video Capture yourself Online Video libraries Animation Capture yourself Online Make using online sites

21. LINKING VS. EMBEDDING  Linking – This is where a multimedia product (e.g. game, presentation etc.) finds the video, animation or sound and displays it. It is a seperate file on the disk.  Embedding – this is where the actual item is inside the product.  Embedding makes the product MUCH larger, but does keep everything in one place. Linking keep all files separate making changes more simpler.  An example would be that you can LINK or EMBED a video inside powerpoint.  What is good and bad about these options?

22. MULTIMEDIA SOFTWARE AdvantagesDisadvantages Can combine images, text, video, sound etc. Multimedia files can take up a lot of space. Can provide interactivity (links etc.)Can take a long time to create files Better than just displaying textTakes a lot of processing power Allows for more creativityGames interaction can be addicting leading to other issues (remember unit 1). Explains ideas more clearly.
