2 Sistem Multimedia

3 Istilah “Multimedia” Terdiri dari dua bagian :
Multi (multus) : “numerous, multiple” Media (medium): “middle, center”. Agen untuk sesuatu, digunakan untuk mendistribusikan dan merepresentasikan informasi. Secara umum, multimedia dapat didefinisikan sebagai penggunaan multiple agent (agen ganda) seperti teks, audio, video, citra untuk mengirimkan dan mempresentasikan informasi kepada pengguna.

4 Istilah “Media” Dapat dikategorikan menjadi beberapa kriteria :
Perception media Representation media Presentation media Storage media Transmission media

5 Perception Media “Bagaimana manusia memperoleh informasi”
Kita memperoleh informasi dari apa yang kita lihat dan apa yang kita dengar Media Visual: Text, graphics, images, video Media Audio: Music, sound and voice

6 Representation Media “Bagaimana informasi diencode di dalam komputer”
Bagaimana informasi direpresentasikan secara internal kepada komputer. Beberapa Pilihan : Text is encoded in ASCII An audio data stream in PCM (Pulse Coded Modulation) Image in JPEG format Video in MPEG format

7 Presentation Media “Media apa yang digunakan untuk memasukkan ke komputer dan mengeluarkan informasi dari komputer” Merujuk ke device-device fisik yang digunakan sistem untuk mereproduksi informasi untuk manusia, misal device audio dan device visual. Input: Keyboards, cameras, microphone, Head Mounted Device (for VR input) Output: Paper, monitors, loudspeakers

8 Storage Media “Dimana informasi disimpan”
Merujuk ke berbagai macam benda yang menyimpan data komputer, seperti magnetic tapes, magnetic disks, or digital optical disks (CD-ROM, CD, DVD)

9 Transmission Media “Media yang digunakan untuk mentransmisikan data”
Merujuk ke benda fisik seperti berbagai jenis kabel, (coaxial cable, twisted pair, fiber optics), radio tower, satellite – yang mentransmisikan sinyal telekomunikasi. Perbedaan antara media transmisi dan media penyimpanan adalah kapabilitas untuk mentransfer dara secara kontinyu melalui jaringan komputer.
