After missing the June 2015 target scheduled for switchover by Nigeria from analog broadcast to digital broadcast, a later date in 2016 was given which has also past without switchover. Now, June 20th, 2017 has been set aside as final date for this switchover from analog to digital broadcasting. Nigerians are optimistic that nothing is going to hinder and obstruct this switchover come this date. It is high time we moved with the rest of the world who have since abandon analog broadcasting for digital broadcasting.
Analog broadcasting involves the use of an outdoor antenna whose direction has to be changed periodically for better reception. Analog broadcasting is characterize by poor picture quality, interference, ghosting, poor audio quality e.t.c. In analog broadcasting, outdoor antenna has to be launched very high and well positioned to get the best reception. Analog broadcasting makes use of frequencies like the UHF (Ultra High Frequency) and VHF (Very High Frequency). UHF are radio frequencies between 300MHz and 3GHz range of frequencies. They are sometimes referred to as decimetre band because their wavelengths is in the range of 1 meter to 1 decimetre. They are applied in television broadcasting, satellite communications e.t.c
VHF on the other hand are radio frequencies in the range of 30MHz to 300MHz. They are used in FM radio broadcast, television broadcast, air traffic control, marine communications e.t.c
Digital broadcasting uses a decoder for its broadcast and is characterized by high picture & sound quality, variety of channels, regular program guide, ability to record programs for future reference e.t.c.
