OTV is an encapsulation protocol that wraps L2 frames in IP packets in order to transport them between L2 domains. Typically this would be between remote datacenters, but it could also be within a datacenter if you needed an easy (expensive) way to extend a VLAN.
IPTV (Internet Protocol television) is the delivery of programming by video stream encoded as a series of IP packets. IPTV is distributed by a service provider and can be free or fee-based and can deliver either live TV or stored video. It can be bundled with other Internet Protocol services, including VoIP and high-speed Internet access.
