Slide 1

Introduction to Information Systems I Multimedia and Communications ISYS 101 Glenn Booker Lecture #3

Slide 2

Multimedia World Multimedia presentations go past the vu-diagram method of presentation applications to mix illustrations, activity, feature, and sound Metaphor gets to be theater rather than a platform presentation Many sight and sound apparatuses are intended for the Web Lecture #3

Slide 3

Interactivity A noteworthy component of mixed media presentations can be the utilization of intuitive components – where the viewer picks their way through the presentation as opposed to seeing a settled arrangement of occasions Normal site pages accomplish intelligence through hyperlinks Lecture #3

Slide 4

Multimedia Hardware Basic data and yield equipment for mixed media incorporate a CD-ROM or DVD-ROM drive, sound card, and speakers (all now standard on PCs) Optional gear incorporates an amplifier, representation tablet, computerized camera, and a TV feature connector Lecture #3

Slide 5

Multimedia Hardware Faster feature cards and 3-5 speakers rather than only maybe a couple (e.g. including a subwoofer or going for encompass sound or theater-grade THX sound) assist too With addressing #3

Slide 6

Multimedia Uses Multimedia is utilized progressively for Computer based preparing (CBT) or training (CBE) Livening up reference materials (reference books) Creating stand-alone deals or data booths, playing a circle of data Even workmanship is beginning to utilize media Lecture #3

Slide 7

Big Files Need Compression Multimedia takes a ton more plate space than content so pressure procedures are vital Algorithms are utilized to ascertain how information can be compacted – these calculations are called “codecs” (for co mpression/dec ompression) Lecture #3

Slide 8

Compression Types Compression strategies can be lossless or lossy Lossless systems hold all of unique information (actually!) Lossy methods give up some low level information subtle element to deliver more elevated amounts of pressure Lecture #3

Slide 9

Graphics Compression Formats GIF (like “gift” without the ‘t’) permits a most extreme of 256 hues (8-bit), utilizes lossless pressure, and is regularly utilized for more straightforward Web representation JPEG permits up to 16.7 million hues (24-bit), is lossy, and frequently utilized for photographs or other complex pictures on the Web Lecture #3

Slide 10

Graphics Compression Formats PNG is another organization like GIF, yet isn’t restrictive (you need to pay eminences to have the capacity to make GIF pictures) Bitmap (BMP) is the Windows standard for primitive illustrations – is regularly without pressure so bitmaps are gigantic A bitmap portrays each pixel’s shading Lecture #3

Slide 11

Graphics Software Graphics programming projects tend to fall into three sorts for working with a solitary picture Paint programs, which utilize bit-mapped or raster design Drawing projects, which utilize vector illustrations Image editors, for adjusting existing photographs Lecture #3

Slide 12

Paint Programs Paint projects are intended to make pictures at the pixel level Easy to make stuff along these lines, yet harder to alter, and harder to keep smooth Examples: Fractal Design Painter, Paint Shop Pro, Corel Painter Lecture #3

Slide 13

Drawing Programs Drawing projects use vector design – every line is depicted by a math equation Draw and shape lines, then fill in hues and surfaces among them Creates smoother pictures, which can be scaled to any size Lecture #3

Slide 14

Drawing Programs Saves reports in EPS group, which a few printers see But EPS isn’t Web agreeable Examples: Adobe Illustrator, Macromedia Freehand, CorelDRAW Lecture #3

Slide 15

Image Editors Image editors are for controlling existing pictures (e.g. photographs) Allow you to resize, product, blend and add embellishments to the pictures Examples: Adobe Photoshop and PhotoDeluxe Lecture #3

Slide 16

Moving Picture Software Programs for working with moving pictures include: 3-D rendering projects, for adding 3-D impacts to representation (lighting, shadows, and so forth.) Animation programs, for making the dream of moving pictures through illustrations Video editors, for making and altering computerized features Lecture #3

Slide 17

3-D Rendering Programs Rendering projects represent particular light sources, and focus shadows, straightforwardness, and different impacts Used to oblige a supercomputer to do this Ray following is one procedure they utilize Examples: Renderman, AutoCAD, 3D Studio MAX Lecture #3

Slide 18

Animation Programs Animation depends on displaying still pictures quickly in progression A motion picture utilizes 24 outlines for each second Computer activity utilizes the same thought with GIF pictures Some projects perceive foundation pictures versus those components which move Lecture #3

Slide 19

Animation Programs Examples: Adobe LiveMotion, Macromedia Flash, and Softimage XSI Some top of the line ($$$) projects consolidate liveliness with 3D rendering, for example, Discreet ignition, Maya Complete, and Newtek Lightwave Lecture #3

Slide 20

Video Editors Video editors take info from an advanced camcorder, and permit it to be revised, include sound, and so on. Samples: Adobe Premiere Lecture #3

Slide 21

Video Formats Videos are more often than not in one of three configurations MPEG is the standard for full movement feature, for example, DVD’s QuickTime is an Apple standard for top notch feature and sound AVI (formally Video for Windows) have a tendency to be genuinely low quality Lecture #3

Slide 22

Streaming Video One approach to get feature over the Internet rapidly is to utilize gushing feature A little bit of feature is sent persistently to the viewer Hence the viewer doesn’t need to download the whole feature before watching it But the viewer additionally never has a feature\'s duplicate either Lecture #3

Slide 23

Audio Software Audio programming has enhanced to where most expert recording studios don’t trouble with attractive tape for recording – they utilize PCs rather Sound uses can extend from straightforward ambient melodies to unique arrangements Lecture #3

Slide 24

Audio Formats Audio is digitized at 44.1 kHz for CD’s Raw sound documents are substantial, consequently pressure is essential MP3 is the most widely recognized organization, can be packed up to 1/12 th of unique size AU arrangement is utilized on Sun workstations WAV records are utilized as a part of Windows, aren’t compacted Lecture #3

Slide 25

Audio Software Musical instruments use MIDI dialect to identify with PCs Audio applications incorporate Notation projects to compose music Recording and altering projects Mixers and synchronizers to facilitate numerous musical parts into one piece Lecture #3

Slide 26

Putting it all together Authoring programming is utilized for collecting interactive media presentations from the greater part of its parts (sound, representation, feature, liveliness) Uses a scripting dialect to facilitate exercises Example: Macromedia Director Lecture #3

Slide 27

Virtual Environments Massive upgrades in mixed media have prompted the idea of making virtual situations Hardware like head-mounted showcases make it conceivable to present a sensible fake environment Lecture #3

Slide 28

Virtual Formats VRML (Virtual Reality Modeling Language) is a leader in giving a virtual domain by means of the Internet Used for recreations, preparing, and information perception One basic diversion environment is the Multi-User Dungeon (MUD) Lecture #3

Slide 29

Telecommunications Some parts of PC systems administration rely on upon the current information transfers framework Most home clients use simple phone lines for their modem association with the Internet Telecom is moving from simple signs on copper wires to computerized signs Lecture #3

Slide 30

Telecommunications Analog wires can go up to T1 speed (1.5 Mb/s) or 24 voice signals Digital signs may be sent crosswise over fiber optic links, or channeled utilizing microwaves Fiber optics can go up to T3 speed (43 Mb/s) or 672 voice signs utilizing beats of light Lecture #3

Slide 31

Telecom Standards Telecom measures are characterized by the ITU, a branch of the United Nations Telecom is an indispensable administration for wellbeing so it is intensely controlled to guarantee administration to unfruitful districts Private or rented lines can be utilized for correspondence too Lecture #3

Slide 32

Modems mo dulate and dem odulate signals That changes over an advanced sign to simple, and back again at the flip side Modem rates developed from 300 bits/sec (around 1970’s) to the hypothetical furthest reaches of 56,000 bps Lecture #3

Slide 33

Modem Standards as far as possible is characterized by the V.90 standard (56 kbps) Earlier guidelines were V.34 (28.8 kbps) and V.32 (14.4 kbps) Modems arrange the speediest association both sides can deal with Faxes can likewise be sent, by and large at 9.6 kbps Lecture #3

Slide 34

Need for Speed Bandwidth, or the pace at which information can be sent and got, is basic for rising applications Video conferencing needs 10 Mbps High definition TV (HDTV) needs 11 Mbps Broadband alludes to computerized telecom at rates of 1.5 Mbps and up (T1 or better) Lecture #3

Slide 35

Broadband Options ISDN is the most well-known broadband administration Basic ISDN goes up to 128 kbps Primary ISDN goes up to 1.5 Mbps (T1) Broadband ISDN doesn’t exist yet; claims up to 622 Mbps Lecture #3

Slide 36

Broadband Options Digital Subscriber Lines (DSL) is still uncommon Some variants are lopsided (you can have much slower transfer speed than download) Range from 128 kbps to 9.1 Mbps velocities Speed fluctuates relying upon how far you are from the supplier SONET is a future probability; range from 52 Mbps to 1 Gbps Lecture #3

Slide 37

Cable Modems Cable modems use coaxial link from your TV link supplier to bolster Internet access Cable transmission capacity is shared among the clients in the neighborhood more clients online means slower speeds for every client Speed can run from 100 kbps to more than 2000 kbps Lecture #3
