3 Secara teknis data adalah, fakta yang masih mentah atau suatu gambaran, seperti pembayaran dan pemesanan, yang diproses menjadi informasi, seperti saldo dan kwantitas dalam persediaan. Pada penggunaan secara umum pemakaian istilah informasi dan data digunakan secara bersinonim. Any form of information whether in paper or electronic form. In electronic form, data refers to files and databases, text documents, images and digitally-encoded voice and video. 3

4 Penyebaran informasi kedalam lebih dari satu format. Meliputi penggunaan teks, audio, grafik, grafik yang bergerak dan full- motion video. Program Multimedia seperti game, encyclopedia dan training courses pada CD-ROM. Setiap aplikasi dibuat dengan Video dan/atau suara dapat disebut suatu program multimedia. –(Computer Desktop Encyclopedia 1999) Suatu Presentasi komputer yang Interaktif yang meliputi sedikitnya dua elemen berikut: teks, suara, grafik, grafik yang bergerak, dan animasi. »(Robert S.Tannembaum, 1999) 4

Pemetaan secara grafik -- memperlihatkan rancangan site secara keseluruhan program Web authoring mendukung rancangan dan HTML coding Authoring tool adalah aplikasi software yang digunakan untuk membuat isi dari multimedia, umumnya untuk WWW (world wide web) 14

15 Web authoring programs Umumnya digunakan untuk membuat site comersial yang bagus (sophisticated commercial site). Dikenal sebagai Web page editors dan HTML (hyper text Markup Language) editors, program ini menyediakan fasilitas untuk merancang web site dan HTML coding Contoh program web authoring adalah macromedia Dream weaver, Netobjects Fusion dan microsoft front page 15

16 Suggestion Creating Web site Buat Rancangan dan motif yang umum Penggunaan grafik dan animasi untuk menambah ketertarikan Buat navigasi yang mudah pada web site Rancang web-site dengan tampilan yang standard 16

17 Rancangan dan motif yang umum Rancangan dan motif yang umum Konsisten dalam penggunaan warna, font (huruf), rancangan background dan fitur-fitur navigasi membuat web-site serasa menyatu dan buatlah mudah digunakan 17

18 Penggunaan grafik dan animasi Menambah ketertarikan Grafik dan animasi menambah minat dan memfokuskan perhatian user Dibutuhkan waktu untuk men- download, dan waktu menunggu itu membuat frustasi user Selektif dan batasi ukuran dari grafik Gunakan ‘reuse graphics’ dari satu page ke page yang lain 18

19 Ciptakan suatu metoda navigasi yang sederhana yang memudahkan para pemakai sampai kepada informasi diinginkan mereka secepat mungkin Jangan membuat isi informasi yang diinginkan lebih dari tiga ‘click’ dari home page Contoh: 19

20 Rancang tampilan yang standard Untuk memperkecil dampak dari site kita yang diakses oleh banyak user, rancangan sebaiknya sesuaikan dengan resolusi standard tampilan dari monitor 800 x 600 (tergantung dari perkembangan teknologi yang ada) 20

33 Bentuk paling dasar penyampaian informasi Paling sederhana Disimpan tidak membutuhkan ‘space’ yang besar Di representasikan dalam bentuk FONT 33

34 AUDIO 34

35 Audio diproses didalam komputer dengan mengubah signal analog ke dalam suatu kode digital dengan menggunakan berbagai teknik Dihasilkan dari pergetaran Kategori –Speech –Music –Efek suara 35

36 Sound cards play digital audio files and usually support MIDI. File audio digital berisikan –‘soundwaves’ yang telah diubah jadi format digital. –Tanpa kompresi, file ini memakai penyimpanan yang pantas dipertimbangkan. (besar ukurannya) Format audio dari Windows adalah wave file (.WAV extension). 36

37 Contain the data to reconstruct the wave E.g. WAV, MP3, AIFF (apple), Real.. Wave Sound files Contain notation representation Require a synthesizer to build the sound that will play the note Non Wave (e.g. Midi) Sound files 37

38 WAV = WAVe (gelombang) Tidak ter-Compress Ukuran Relatif besar Kualitas Suara setara audio CD Standard file pada PC Diciptakan oleh microsoft OS selain windows juga dapat menggunakan file jenis ini 38

39 WAV files use the.WAV extension and allow different sound qualities to be recorded. Either 8-bit or 16-bit samples can be taken at rates of Hz, Hz and Hz. The highest quality (16-bit samples at Hz) uses 88KB of storage per second. 39

40 (Musical Instrument Digital Interface) A standard protocol for the interchange of musical information between musical instruments, synthesizers and computers. It defines the codes for a musical event, which includes the start of a note, its pitch, length, volume and musical attributes Set of cables, data structures & protocol for inter device communication for playing digital sound & music Midi Enable different musical instrument from different manufacturer & computer to communicate each other 40

41 MIDI (lanj) Begin in late 70’s – early 80’s, many synthesizer keyboard product appear in the market Compatibility problem, unable to co-orperate each other 1983 group founded by Roland, Yamaha, KORG, Sequential, Oberheim & Kawai to define standard called MIDI Today, Supported by major music manufacturer and music company 41

43 MP3 (MPEG Audio Layer 3) An audio compression technology that is part of the MPEG-1 and MPEG- 2 specifications. Developed in Germany in 1991 by the Fraunhofer Institute, MP3 compresses CD-quality sound by a factor of 12, while providing almost the same high fidelity. Greater compression ratios are also obtainable that provide reasonable sound quality. MP3 music files are played via software or a handheld device. MP3 has made it feasible to download quality audio from the Web very quickly, causing it to become a worldwide auditioning system for new musicians and labels. 43

44 MP3 44 Dikenalkan tahun 1992 File sudah terkompresi (bisa sekitar 12 : 1) dg cara menghilangkan bagian-bagian suara yang tidak dapat didengar oleh telinga manusia Ukuran relatif kecil Kualitas suara cukup bagus

45 MP3 (MPEG Audio Layer 3) Copyrighted material is also offered for a fee, or sometimes for free, creating a major legal issue. Enthusiasts feel MP3 will revolutionize music distribution via the Web, since an entire audio CD (an hour of music) can be downloaded in five minutes. Major music publishers are trying to cope with this new phenomenon by introducing a system for copyright protection (see SDMI and Windows Media Rights Manager). There are numerous MP3 "rippers" and encoders on the market that pull out raw audio data from a music CD and encode it into the MP3 format. 45

46 AA = Audible Audio (e-books) AAC= Advanced Audio Coding AIFF = Audio Interchange File Format ASF = Advanced Streaming Format MP3 = Moving Pictures Expert Group Audio Layer 3 WAV = Windows Waveform WMA = Windows Media Audio RA= RealAudio sound file QT = QuickTime audio 46

47 Streaming Some applications on the Web using streaming audio Streaming is the process of transferring data in a continous and even flow Streaming allows users to access and use a file while it is transmitting For example, Streaming audio enables to listen the music as it downloads to computer Accepted standards supported by most web browsers for transmitting streaming audio data on the internet are MP3, QuickTime, Windows Media Format and RealAudio 47

48 How Streaming Media Works Step 1 When you first click on a link to a media clip, your web browser requests the clip from a media server on the Internet. Step 2 The server returns the data to your computer in a continuous stream. 48

49 How Streaming Media Works Step 3 Your computer launches a media player. Step 4 The streaming data is stored in a buffer. Step 5 Once enough data has been received, the clip begins to play. 49

50 Real-time Streaming Vs Progressive Download Progressive download allows users to watch or listen to media as it is being downloaded from a standard web server (such as Apache,) to their hard drive. This method works best for short-form media where file size is limited. Progressive download ensures high-quality playback regardless of users' Internet connection speed, although users with slower connections will wait longer before media starts to play. 50

51 Real-time Streaming Vs Progressive Download Real-time streaming using Streaming Server delivers media in real time over the Internet, from modem to broadband rates. With the open standard Real-Time Transport Protocol/Real-Time Streaming Protocol (RTP/RTSP), no file is ever downloaded to a viewer's hard drive. Media is played, but not stored, by the client software as it is delivered. Real-time streaming is often preferable to progressive download for webcasts of live events, delivery of long-form video, and 24/7 Internet radio and TV channels. 51

54 Vector Graphics and Bitmapped GraphicsVector Graphics and Bitmapped Graphics Two methods are used for storing and maintaining pictures in a computer. The first method, called vector graphics, maintains the image as a series of points, lines, arcs and other geometric shapes. The second method, called bitmapped graphics and also known as raster graphics, resembles television, where the picture image is made up of dots. Understanding these two methods and how they intertwine is essential. 54

55 Graphics ( vector) Representasi spatial dari obyek Disusun dari bangun-bangun grafis seperti garis, persegi panjang, bulat, dsb yang ditempatkan secara matematis dengan koordinat, ukuran, ketebalan sisi dan pola pengisian pada bidang Dibuat dengan menggunakan ‘draw’ (misal: Coreldraw, Adobe Illustrator) Gambar-gambar yang bukan foto-realistik Ukuran relatif kecil Resolution independent 55

56 Graphics ( raster) Representasi dari obyek Disusun secara matriks nilai numerik yang merepresentasikan setiap titik /pixel Dibuat dengan menggunakan paint/image editing (Misal :Photoshop, Corel Photopaint) Foto Gambar-gambar yang rumit yang membutuhkan rincian halus Ukuran relatif lebih besar (dibandingkan dengan vektor) 56

57 2 D graphics –Bitmap (raster) based graph –Vector based graphics –Metafile (contain both) Metafile –A file that contains other files. –It generally refers to graphics files that can hold vector drawings and bitmaps. –For example, a Windows Metafile (WMF) can store pictures in vector graphics and bitmap formats as well as text. –A Computer Graphics Metafile (CGM) also stores both types of graphics. 57

58 What is 3D computer graphics ? –Computer based system to construct image from object based on vector –The object, also called wire frame, “wrapped” with digital texture and rendered to create photo realistic images –This images usually called CGI – computer Generated Images 58

59 Application of 3D computer Graphics –Illustration & graphic art –Broadcast & film –Games –Simulation & Visualization –CAD/CAM – Engineering –Architecture & Virtual Reality –Presentation Graphics 59

61 Moving diagrams or cartoons that are made up of a sequence of images displayed one after the other. Animation files take up much less disk space than a true video sequence. Kumpulan dari gambar-gambar Gabungan dari frame-frame gambar secara cepat untuk menghasilkan suatu gerakan 61

62 BMP file (BitMaP file) Also known as a "bump" file, it is a Windows and OS/2 bitmapped graphics file format. It is the Windows native bitmap format, and every Windows application has access to the BMP software routines in Windows that support it. BMP files provide formats for 2, 16, 256 or 16 million colors (1-bit, 4-bit, 8-bit and 24-bit color). BMP files use the.BMP or.DIB extensions (DIB stands for Device-Independent Bitmap). 62

63 JPEG (Joint Photographic Experts Group ) Pronounced "jay-peg." An ISO/ITU standard for compressing still images that is becoming very popular due to its high compression capability. Using discrete cosine transform, it provides lossy compression (you lose some data from the original image) with ratios up to 100:1 and higher. It depends on the image, but ratios of 10:1 to 20:1 may provide little noticeable loss. The more the loss can be tolerated, the more the image can be compressed. Compression is achieved by dividing the picture into tiny pixel blocks, which are halved over and over until the ratio is achieved. JPEG uses the JPEG File Interchange Format, or JFIF. File extensions are.JPG or.JFF. M-JPEG and MPEG are variations of JPEG used for full-motion digital video. 63
