Teknologi Video Mixer

Teknologi informasi yang dewasa ini sedang digandrungi oleh masyarakat, telah mengalami tiga kali masa revolusi. Revolusi pertama adanya revolusi bidang Computasi atau berkaitan dengan penggunaan komputer untuk kegiatan yang sifatnya matematis. Revolusi yang kedua adanya networking atau masyarakat lebih mengenalnya dengan internet, sedangkan revolusi yang ke tiga disebut dengan perkembangan Multimedia.

Teknologi multimedia saat ini sangat dibutuhkan oleh masyarakat karena fungsinya yang cukup beragam untuk berbagai kepentingan, seperti kepentingan bisnis, ekonomi, sosial termasuk juga pendidikan. Kekuatan multi media karena mampu menyajikan pesan secara lengkap meliputi unsur-unsur animasi, teks, gambar, video dan suara yang dapat digabungkan secara lengkap dan harmonis. Dengan kekuatan inilah pesan dalam suatu multimedia dapat mudah dicerna oleh user dan audience. Sehingga dengan kekuatan yang dimiliki mulimedia prospek dan urgensinya akan terus dibutuhkan dalam masyarakat.

Perkembangan teknologi yang semakin pesat memberi kesempatan untuk mengembangkan berbagai aplikasi elektronika. Di antara perkembangan tersebut adalah suatu piranti yang dapat mengontrol output video yang diinginkan dari beberapa input video. Piranti ini didasarkan pada suatu kebutuhan dalam dunia multimedia, yaitu di antaranya video mixer. Kebutuhan tersebut muncul karena pada umumnya pada suatu event digunakan beberapa kamera video yang secara langsung pada layar Liquid Crystal Display (LCD). Pada aplikasi ini digunakan beberapa input video dan output video. Untuk melakukan seleksi terhadap video digunakan rangkaian untuk memilih input video yang ingin untuk ditampilkan. Selain secara manual, pemilihan input video dapat dilakukan secara otomatis dengan menggunakan mikro kontroler. Proses mixing yang dilakukan adalah melakukan control intensitas dari sinyal video. Dalam penelitian ini alat video mixer yang dapat diprogram telah direncanakan, dibuat, dan diuji bekerja dengan baik sesuai dengan fungsinya.

Dengan berkembangnya teknologi memberi dampak yang besar pula dalam bidang multimedia. Salah satunya adalah melakukan penyiaran langsung dari beberapa input kamera/ video pada layar LCD proyektor. Hal ini memberi pengaruh yang besar pada dunia entertainment karena akan menambahkan kenyamanan dan kemudahan bagi penonton.Masalah yang dihadapi dalam sebuah penyiaran langsung adalah bagaimana menampilkan video pada monitor/ LCD proyektor dengan input  yang bermacam-macam dengan kontrol manual (operator) ataupun secara programmable.

Video Mixer merupakan alat untuk menggabungkan gambar dari komputer (VGA) dan gambar dari sumber Video lainnya, seperti Handycam, CCTV Camera, DVD, dll. Keluaran dari alat ini dapat dihubungkan ke TV, alat perekam atau alat pemancar untuk broadcasting. Penggunaan alat ini sangat mudah. Cukup sambungkan kabel pada bagian input dan output-nya saja. VGA-Video Mixer ini biasa digunakan sebagai text generator, untuk menyisipkan tulisan-tulisan, logo, ataupun data-data lainnya dari komputer pada video dari Handycam, CCTV Camera atau sumber lainnya. Bisa juga digunakan untuk membuat content karaoke.
