That's one of the biggest advantages of Ultraflix ( sub4Mbps) there is no market when a company can't deliver the goods. According to Akamai worldwide average internet speed is 3.6Mbps. Ittiam ( Indian company) and NTEk demonstrated that using their own optimized HEVC and VP9 encoding stream 4k as low as 3mbps can be done. If that's the case competitors that require 15Mbps and up can't even compete with ultraflix. Penetration of ultraflix will expedite 4k growth and will be phenomenal especially when 4k TVs are selling in millions worldwide.
