Internet Protocol TV (IPTV) also streams content to customers via internet protocol.
The difference, however, is OTT content is streamed over the public internet. IPTV services, on the
other hand, use fully-controlled private, dedicated networks which cost more but can result in better
quality of service.
Some examples of popular IPTV services include Sling TV,
Hulu Live TV, YouTube TV, and DirecTV Now.
IPTV services may be classified as live, time-shifted or catch-up (show replays) and
video on demand (VOD) where user may choose from a catalogue of videos.
Like cable TV, IPTV usually works with a set-top box (STB) connected to the user’s TV.
It benefits from tighter control and guaranteed bandwidth, but, since the STB is tied to one network and
one device, unlike OTT, it cannot serve content to viewers on the go.
