Multimedia Features And Classification
                     MULTIMEDIA FEATURES AND 
CLASSIFICATION
Multimedia Systems
• A multimedia system is responsible for developing a multimedia application. A multimedia application is a 
bundle of different kinds of data. 
• A multimedia computer system is one that can create, integrate, store, retrieve delete two or more types 
of media materials in digital form, such as audio, image, video, and text information.

MAJOR FEATURES
Very High Processing Power
• To deal with large amount of data, very high processing power is used.

File System
• File system must be efficient to meet the requirements of continuous media. These media files requires 
very high-disk bandwidth rates. 
• Disks usually have low transfer rates and high latency rates. To satisfy the requirements for multimedia 
data, disk schedulers must reduce the latency time to ensure high bandwidth.

File formats that support multimedia
• Multimedia data consists of a variety of media formats or file representation including ,JPEG, MPEG, AVI, 
MID, WAV, DOC, GIF,PNG, etc. AVI files can contain both audio and video data in a file container that allows 
synchronous audio-with-video playback.

Input/Output:
• In multimedia applications, the input and output should be continuous and fast. Real-time recording as 
well as playback of data are common in most of the multimedia applications which need efficient I/O.

Operating System:
• The operating system must provide a fast response time for interactive applications. High throughput for 
batch applications, and real-time scheduling.

Network Support
• It includes internet, intranet, LAN, WAN, ATM, Mobile telephony and others. In recent years, there has 
been a tremendous growth of multimedia applications on the internet like streaming video, IP telephony, 
interactive games, teleconferencing, virtual world, distance learning and so on.

CLASSIFICATION
Multimedia Classification
• Text - The form in which the text can be stored can vary greatly. 
• Graphics - There is great variance in the quality and size of storage (Image file formats) for still images 
(Bitmap - gif, jpg, bmp) (Vector - svg, pdf, swf, ps). 
• Audio - An increasingly popular datatype (audio file format) being integrated in most of applications is 
Audio. Its quite space intensive. 
• Animation - It involves the appearance of motion caused by displaying still images one after another.
• Video - One on the most space consuming multimedia data type is digitalized video.
