My colleague, Dean Bubley, tweeted last night (here) on the subject of OTT video monetization by MNOs: "Increasingly convinced that idea of MNOs "monetising OTT apps" is a complete chimaera. Wishful thinking. More likely money-flow is other way". Dean also linked a 3GPP work program that "deprioritised the key standard & put it "on hold" (here).
Obviously vendors in this space think differently. 4 of them - Avvasi, BroadHop, Commprove (see "BroadHop and CommProve Offer Integrated RAN Congestion Management Solution" - here) and Spirent (here) have just formed Connexus.
See the press release - "CONNEXUS Ecosystem Unveils Architecture that Highlights New Possibilities for Monetizing OTT Video Traffic" - here.
