IPTV and OTT both use internet as content deliver mechanism. However outside that they are widely different i.e. business model, quality of service, quality of content, ownership, cost etc.
OTT streaming is the delivery of audio/video content using regular & unmanaged internet.
IPTV uses dedicated network/infrastructure provided by operator. IPTV is a closed, proprietary network and therefore provides high quality, reliable network with control over quality of services.
