Public Lecture “Digital TV on Mobile”

On February 14, 2011, a public lecture entitled "Digital TV on Mobile" was held in the multimedia room of STEI ITB. The keynote speaker was Prof. Okada Minoru from the Nara Institute of Science and Technology (NAIST), Japan. The lecture, attended by approximately 90 students, ran from 9:00 a.m. to 12:00 p.m.

Prof. Okada Minoru, a member of the communications laboratory at NAIST, explained the development of television. It began in 1884 with the introduction of analog television, and continued with developments in 1925. The first broadcast took place in 1928 in New York, also the year color television first appeared.

The development of digital TV began in 2003. Digital TV is the transmission of audio and video using digital signals, as opposed to the analog signals used by analog TV. Countries like the United States replaced analog over-the-air television broadcasts with digital television to allow for alternative uses of the radio spectrum previously used for analog TV broadcasts.

It wasn't until 2006 that mobile DTV became known. Now, most of us have large-screen digital TVs, and it's time to switch to mobile digital TV. Digital mobile TV is incredibly practical and easy to carry around.

He explained that there are several technologies that support DTV, including:
1. Video encoding -> functions to compress images and can be transmitted at a low bitrate
2. Errorcorrection coding
3. Wireless transmission.
