Multimedia Hardware By: Yang Chen
Multimedia: • the use of computer to present and combine text, graphics, audio, and video with links and tools that let the user navigate, interact, create, and communicate.
This definition contains four components: • First, there must be a computer to coordinate what you see and hear, and to interact with. • Second, there must be links that connect the information. • Third, there must be navigational tools that let you traverse the web of connected information. • Finally, there must be ways for you to gather, process, and communicate your own information and ideas.
Four factor make the shopping difficult: • There is no industry-wide standard for multimedia. • Each vendor creates its own brand and produces multimedia applications that work with only its brand. • There are so many options you can add on to a multimedia computer that once you decide which brand to buy.
It is hard to get a list of all the options that are available, because vendors are only interested in showing those they sell. • Once you buy your computer and select the options you want, installing and getting them to work can be a nightmarish experience.
Microsoft’s MCI • MCI stands for Media Control Interface. • Provides users with a strategic approach to coping with this lack of standardization.
Cont. • The purpose of the MCI is to provide a device-independent means of developing multimedia software. • The idea is that vendors who make multimedia hardware supply an MCI translation table for each device. • Developers use MCI commands that get converted automatically by the translation table into the specific instructions needed to control the device.
Apple’s QuickTime • It is to the Macintosh. • Same as the MCI is to Windows. • It supports digital audio, MIDI, compact disc, and digital video. • Apple’s latest release contains many improvements over the original QuickTime.
Cont. • A faster data rate plays digital video more smoothly. • Audio compression reduces the amount of storage required to hold digital audio recordings. • QuickTime now supports MPEG, which may emerge as an industry-wide standard for digital video.
Five categories of components: • System unit • Multimedia accessories • Read/write storage • Communication options • Other input devices
System Unit • CPU • RAM • Color display • Pointing Device • Multimedia Accessories • CD-ROM • Digital Audio • Audio speakers • Video overlay • Digital video • Etc.
Read/Write Storage • Hard disk • Small Computer System Interface • Communication option • Modems • Networks • Internet Connections • Other input device • Scanner • Digital cameras
Specific “Demands” • Graphics • Sound • Large-format storage • Network performance and reliability
Desktop Systems and Workstations • Stand-alone systems, connected to similar machines in a network. • 32 (or 64) bit multi-tasking, multi-user operating system • Specialized display systems • High-quality hardcopy output devices • Large amounts of network storage
Questions • Have you ever used a trackball? What advantages does it have over a mouse? What are the disadvantages? Which do you prefer? • Does your multimedia PC have MIDI connections? Have you ever used an application that would have benefitted from MIDI In or MIDI OUT connections?
