The Director-General of NBC, Mr Ishaq Kawu made this known during a news conference on Digital Switch Over (DSO) held in Lagos on Friday.
Kawu said that the number was arrived at by dividing 191 million Nigerians by six, which represented the number of a household.
He said that the DSO process was a huge financial, technical and logistical challenge.
According to him, switching on a huge country like Nigeria requires tremendous financial commitment.
He said that an STB costs 45 dollars and the commission had made a commitment of eight million units which would amount to 26 million dollars.
According to him, the price is a huge cost for Nigerians hence, the Federal Government has to subsidise it to N1, 500 per STB.
“We are looking at 20 dollars per box so that it will be affordable. We are trying as much as possible to manufacture the boxes locally.
“Similarly, our Set-Top-Box manufacturers has committed resources to the importation of 850, 000 STBs from China.
“But because the EFCC had seized funds from the NBC under the ancient regime at the NBC, we cannot meet our commitment, which totaled the sum of 26million dollars.
“Thankfully, President Muhammadu Buhari, who had always been convinced of the importance of Nigeria’s DSO process, finally approved release of the seized sum of N10 billion to the NBC. That took place in September 2016,” he said.
Kawu said that the DSO was successfully carried that out in Abuja in December 2016, offering in the process 30 local, regional and national channels to viewers.
He said that there was an upgrade to the 15 channels offered in Jos, Plateau, when the NBC launched the pilot phase of DSO in April 2016.
