Three types of IPTV
IPTV comes in three different flavors. The first kind—and the one you're probably using already—is called video on demand (VOD). With a service such as Netflix (an online movie website), you select a TV program or movie you want to watch from a wide range, pay your money, and watch it there and then. A different kind of IPTV is being offered by some of the world's more enterprising TV broadcasters. In the UK, the BBC (British Broadcasting Corporation) makes its last week's programs available online using a web-based streaming video player called the BBC iPlayer. This kind of service is sometimes called time-shifted IPTV, because you're watching ordinary, scheduled broadcasts at a time that's convenient for you. The third kind of IPTV involves broadcasting live TV programs across the Internet as they're being watched—so it's live IPTV or IP simulcasting. All three forms of IPTV can work either using your computer and an ordinary web browser or (for much better quality) a set-top box and an ordinary digital TV. All three can be delivered either over the public Internet or through a managed, private network that works in essentially the same way (for example, from your telephone and Internet service provider to your home entirely through the provider's network).
How does IPTV work?
With traditional TV, programs are broadcast by being turned into radio waves and beamed through the air to a rooftop antenna on your home. The antenna converts the waves back into electrical signals and your TV set decodes them to make its sound and picture (satellite TV works the same way, except the signal bounces into space and back, while cable TV sends the signal directly into your home without radio waves). How is IPTV different?
The future of broadcasting?
There's no great clamor from ordinary TV viewers for IPTV, although that's not unusual where new inventions and innovations are concerned; no-one can truly appreciate something they haven't yet experienced. But the huge popularity of VOD websites such as BBC iPlayer and time-shifting personal video recorders (PVRs) such as TiVO (and Sky+ in the UK) strongly suggest TV will move increasingly away from broadly defined channels and rigid schedules to more narrowly focused, pay-per-view programming.
Even so, consumer demand won't be the main driving force in the transition from 20th-century broadcast TV to 21st-century IPTV—at least, not to begin with. In the last decade or so, traditional telephone companies, faced with competition from cable-based rivals, have had no choice but to redefine themselves as information service providers, offering Internet connectivity as well as phone services. The more powerful and enterprising among them now see a further business opportunity by redefining themselves so they offer telephone, Internet, and TV services simultaneously. Cable companies already offer all three services in attractive bundles; IPTV makes it possible for telephone providers and broadcasters to join forces and compete. In the longer term, who knows whether people will even regard TV, telephone, and the Internet as separate entities, or whether they will continue to converge and merge?
Delivering IPTV sounds easier than it may prove in practice. The biggest inhibitor at the moment is that too few homes have broadband connections with enough capacity to handle a single high-quality TV stream, never mind several simultaneous streams (if there are several TVs in the same home). Upgrading ordinary broadband connections to fiber-optic broadband, so they routinely provide homes with 10–100Mbps, will take time and considerable investment. Until that happens, IPTV providers will not be able to guarantee a "quality of service" (often referred to as QoS or sometimes a "quality of experience," QoE) as good as TV delivered through cable, satellite, or across the airwaves. Latency (delays in packet arrival) and packet loss are problems enough for VoIP (Voice Over Internet Protocol) telephones, and they become much more of an issue when broadcast-quality video is added into the stream. Since IPTV uses compressed video formats such as MPEG2 and MPEG4, packet loss has a much more serious effect than it would have on uncompressed video or audio streams: the higher the compression rate, the bigger the effect every lost packet has on the picture you see.
With luck, IPTV may take off in exactly the same way as broadband Internet did in the early 2000s: back then, as more people used the Internet, they felt hampered by the limitations of dial-up connectivity, demanded (and showed they were willing to pay for) higher-quality broadband, and provided enough revenue for the telecommunications companies to upgrade their networks. Once viewers start to experience the convenience, control, and interactivity of IPTV, higher bandwidth Internet connections that make it possible seem certain to follow.
