Definition

● Multimedia is a form of communication that uses a combination of different content forms such as text,

audio, images, animations, graphics or video into a single interactive

presentation(en.wikipedia).

● Multimedia consists of: applications that use multiple modalities to their advantage, including text,

images, drawings, graphics, animation, video, sound (including speech), and, most likely,

interactivity of some kind.

● The basic advantage of multimedia over the conventional form of media which uses sound, graphics and

text for example TV, audio etc. is the interactive feature of multimedia.

● It provides the interaction between user and information that makes it a very powerful media for

activities that require the process of communicating information, such as education and training,

reference material, business presentations, manuals, multimedia databases, geographic information

system, advertising, documentaries and so on.

Elements of Multimedia

● Text

● Facsimile (or fax)

● Document images

● Photographic images

● Geographic Information System maps

● Voice commands and synthesis

● Audio messages ● Video messages

● Graphics

● Moving graphics (animation)

● Full-motion stored and live video

● Holographic images

● Fractals

● Animation

● Hyperlinks

● Interactivity

● Graphics

Videos are moving visual sequences that capture real-life events or animations. They can be used to demonstrate processes,

tell stories, showcase products, or present information through motion and visuals. Video messages refer to a message that

could be sent to a destination using video transmission media.

● Facsimile:

A facsimile is a copy or reproduction of an old book, manuscript, amp art print, that is as true to the original

copy. Facsimile transmission was the first practical means of transmitting document images over the

telephone lines.

● Geographical Information Systems:

The GIS maps are being used widely for natural resources and wildlife management as well as urban

planning.

● Voice Commands and Voice Synthesis:

Voice commands are being used for hands-free-operation for computer programs. Voice synthesis is used

for presenting the results of an action to the user in a synthesized voice.

● Full motion stored and Live Video (FMV):

Full motion video started out as a very useful idea for online training and maintenance manual. The

evolutionary step of FMV is video conferencing.

● Holographic images: Holographic images extend the concept of virtual reality by allowing the user to get

―inside a part such as an engine and view its operations from inside.

● Fractals: This technology is based on synthesizing and storing algorithms that describe the information.

● Animation:

Animation involves the creation of moving and dynamic visuals. It brings static elements to life and

can be used to demonstrate concepts, create interactive experiences, or add visual interest and

engagement to multimedia content.

● Interactivity:

Interactivity allows users to engage with the multimedia content and actively participate in the experience.

It can include clickable buttons, menus, navigation, quizzes, games, and other interactive elements that

enable users to control and manipulate the content.

● Hyperlinks:

Hyperlinks are clickable elements that allow users to navigate between different parts of the multimedia or

to external sources. They provide a way to access additional information, related content, or relevant

resources.

● Graphics:

3. It can be expensive: Multimedia makes use of a wide range of resources, which can cost you a large

amount of money.

4. Too much makes it impractical: Large files like video and audio has an effect of the time it takes for your

presentation to load. Adding too much can mean that you have to use a larger computer to store the files.

In case you want to upload it onto the Internet, there are a few factors to keep in mind, for example

bandwidth and the user’s abilities.

Multimedia Hardware

A multimedia system includes the following components:

1. Capture Devices

-- Video Camera, Video Recorder, Audio Microphone, Keyboards, mouse, graphics tablets, 3D input devices,

tactile sensors, VR devices.

2. Storage Devices

-- Hard disks, CD-ROMs, Jaz/Zip drives, DVD, etc

3. Communication Networks

-- Ethernet, Token Ring, FDDI, ATM, Intranets, Internets.

4. Computer Systems

-- Multimedia Desktop machines, Workstations, MPEG/VIDEO Hardware

5. Display Devices

-- CD-quality speakers, HDTV,SVGA, Hi-Resolution monitors, Colour printers etc.

Multimedia Software

● Music sequencing and notation

● Digital audio

● Graphics and image editing

● Video editing

● Animation

● Multimedia authoring

● Multimedia broadcasting

1. Music Sequencing and Notation

Music sequencing refers to using a software to record, save, edit and play audio files. Audio files can be

stored in numerous forms such as MIDI(Musical Instrument Digital Interface), OSC(Open Sound Control), etc.

Cakewalk by Bandlab

Music Sequencer (Try onlinesequencer/sequences )

Avid Pro Tools

Pro Tools is a high-end integrated audio production and editing environment that runs on Macintosh

computers as well as Windows. Pro Tools offers easy MIDI creation and manipulation as well as powerful

audio mixing, recording, and editing software. Full effects depend on purchasing a dongle.

3. Graphics and Image Editing

Adobe Illustrator

Illustrator is a powerful publishing tool for creating and editing vector graphics, which can easily be exported

to use on the web. It is especially useful for logo graphics design.

Adobe Photoshop

Photoshop is the standard in a tool for graphics, image processing, and image manipulation. Layers of

images, graphics, and text can be separately manipulated for maximum flexibility, and its set of filters permits

creation of sophisticated lighting effects.

GIMP

GIMP is a free and open-source graphics editor alternative to Photoshop. It supports many bitmap formats,

such as GIF, PNG, and JPEG. These are pixel-based formats, in that each pixel is specified. It also supports

vector-based formats, in which endpoints of lines are specified instead of the pixels themselves, such as

SWF (Adobe Flash). It can also read Photoshop format.

5. Animation

● Multimedia APIs

Java3D is an API used by Java to construct and render 3D graphics, similar to the way Java Media

Framework handles media files. It provides a basic set of object primitives (cube, splines, etc.) upon which

the developer can build scenes. It is an abstraction layer built on top of OpenGL or DirectX (the user can

select which), so the graphics are accelerated.

DirectX, a Windows API that supports video, images, audio, and 3D animation, is a common API used to

develop multimedia Windows applications such as computer games.

OpenGL was created in 1992 and is still a popular 3D API today. OpenGL is highly portable and will run on

all popular modern operating systems, such as UNIX, Linux, Windows, and MacOS.

● Animation Software

Autodesk 3ds Max (formerly 3D Studio Max) includes a number of high-end professional tools for character

animation, game development, and visual effects production. Models produced using this tool can be seen

in several consumer games, such as for the Sony Playstation.

Autodesk Maya is a complete modeling, animation, and rendering package. It features a wide variety of

modeling and animation tools, such as to create realistic clothes and fur. Autodesk Maya runs on Windows,

MacOS, and Linux.

Blender is a free and open-source alternative to the paid Autodesk suite of tools. It also offers a complete

modeling, animation, and rendering feature set, as well as Python scripting capabilities.

● GIF Animation Packages

For a much simpler approach to animation that also allows quick development of effective small animations

for the web, many shareware and other programs permit creating animated GIF images. GIFs can contain

several images, and looping through them creates a simple animation. Linux also provides some simple

animation tools, such as animate.

6. Multimedia Authoring

Tools that provide the capability for creating a complete multimedia presentation, including interactive user

control, are called authoring programs.

Adobe Dreamweaver

Dreamweaver is a web page authoring tool that allows users to produce web-based multimedia presentations

without learning any HTML.

Adobe Animate

Unreal Engine offers high-fidelity visuals out of the box, unlike Unity, but has a steep learning curve. It is

commonly used by and for large game development studios targeting high-quality visual effects with the

latest hardware.

7. Multimedia Broadcasting OBS, XSplit

OBS and XSplit are two widely used broadcasting tools. OBS is free and open source, while XSplit is

proprietary and paid. These tools can be thought of as an entire broadcasting production studio in digital

form. They offer built-in support for switching between different cameras and other multimedia sources for

real-time broadcasting. Users can broadcast live video feeds to websites like YouTube Live, Mixer, Twitch,

and various other live streaming websites.

Distributed Multimedia Systems

Distributed multimedia systems are networked systems that handle the storage, distribution, and playback

of multimedia content across multiple nodes. These systems are designed to handle the unique

requirements of multimedia data, such as audio, video, images, and other related information. By distributing

the processing and storage of multimedia content, distributed multimedia systems offer scalability, improved

performance, and efficient utilization of resources. Here are some key aspects of distributed multimedia

systems:

● Media Storage: Distributed multimedia systems store multimedia content across multiple nodes or

servers. The content may be divided into smaller chunks or segments, and these segments can be

distributed across different nodes based on a specific scheme or algorithm. By distributing the storage,

the system can accommodate large volumes of multimedia data.

● Content Distribution: Distributed multimedia systems use various techniques to distribute multimedia

content efficiently. Content delivery networks (CDNs) are often employed to cache and distribute

congestion. Replication of content across multiple nodes helps improve content availability and

reduces the load on individual servers.

● Streaming and Synchronization: Streaming is a common method used in distributed multimedia

systems to deliver multimedia content to users in real-time. Content is divided into small

segments, and these segments are transmitted to the user's device progressively, allowing playback

to start before the entire file is received. Synchronization is crucial in multimedia systems to ensure

that different media components, such as audio and video, are played back in perfect coordination.

● Quality of Service (QoS): Multimedia systems often require guaranteed levels of QoS to ensure a

satisfactory user experience. QoS mechanisms in distributed multimedia systems involve bandwidth
