Instead of using broadcast TV, cable TV, or satellite signals, IPTV (Internet Protocol television) uses the Transmission Control Protocol/Internet Protocol (TCP/IP) suite to deliver television programming and other video content.
A service provider will often offer an IPTV service that transmits live TV or on-demand video content through IP networks.
It is possible to use an IPTV system to deliver video content through a private network in an organization, but due to complexity, network latency, and scaling concerns, such implementations are much less prevalent than subscriber-based models.
History of IPTV
When Bill Carrico and Judith Estrin founded Precept Software in 1995, the word “IPTV” first appeared. IP/TV is a web video product created by Precept. IP/TV was a Windows and Unix-based program that was Mbone-compatible and used both IP multicast and unicast Real-time Transport Protocol (RTP) and Real-time control protocol to transmit single- and multi-source audio and video data in resolutions ranging from low to DVD quality (RTCP). Cha Chee Kuan, Karl Auerbach, and Steve Casner contributed the most to the software’s creation. Cisco Systems bought Precept in 1998.  IP/TV remains a trademark owned by Cisco.
What is the Operation of Internet Protocol TV?
A managed or dedicated network, such DSL connectivity, is frequently used to deliver IPTV content. A private network allows network operators more control over the video traffic than the public internet does, enabling them to guarantee service quality, uptime, capacity, and dependability.
All programs is aired concurrently in a multicast fashion in traditional television delivery. By switching the TV channel, viewers choose programs from the available program signals as they flow downstream.
In contrast, an IPTV service uses a unicast format and only transmits one show at a time. Only the program the end user chooses is transferred to the user’s device; all other content stays on the internet service provider’s network.
A new stream is sent straight to the viewer from the provider’s server whenever a viewer switches the channel. IPTV requires a set-top box or other customer premises equipment, like a Wi-Fi router or a fiber optic or broadband internet connection, just like cable television.
For IPv4-based live television broadcasts and Real-Time Streaming Protocol for on-demand content, IPTV largely makes use of IP multicasting. On IPv6 networks, multicast listener discovery is employed. Real-Time Messaging Protocol and Hypertext Transfer Protocol are two additional popular protocols.
The IPTV Components
- IPTV head-end: a location where IP multicast streams of live TV channels and AV sources are encoded, encrypted, and transmitted.
- Video on Demand (VOD) Platform, where IP unicast streams of on-demand video assets are stored and made available to users upon request. The VOD platform may occasionally be housed alongside the IPTV headend and regarded as a component of it.
- Interactive Portal: enables user exploration of various IPTV services, including the VOD library.
- Delivery Network: the IP packets’ packet-switched network (unicast and multicast).
- Endpoints: User hardware capable of requesting, decoding, and delivering IPTV streams to the user for display. This can apply to set-top boxes, laptops, and mobile devices.
- Home TV Gateway: a piece of hardware that terminates the access link from the delivery network at the residence of a residential IPTV user.
- User Set-top Boxes are the endpoint devices that decode and decrypt TV and VOD broadcasts so they may be seen on a TV.
What are Use Cases for IPTV?
IPTV can be combined with other IP-based telecommunication services like voice over IP and high-speed internet because it employs a packet-based delivery method.
Time shifting, a general term for TV services that allow viewers to consume content in ways other than live broadcasts, such as digital recording, on-demand television shows, and the ability to rewind or restart a live program already in progress, is another service and application that providers can support thanks to the use of IP. These services and applications include video on demand, interactive TV, live streaming, in-program messaging, and video on demand.
Another delivery method known as internet TV, which denotes the distribution of television programs over a website using a broadband connection, competes with IPTV.
What is the Advantage of IPTV?
Additionally, a switched IP network enables the transmission of substantially more functionality and information. In a conventional TV or satellite network, all the content continuously flows downstream to each customer using broadcast video technology, and the consumer switches the content at the set-top box. The customer has access to as many options as the telecom, cable, or satellite provider can fit into the home’s pipe. An IP network with switches operates differently. Only the content the consumer chooses is delivered to the customer’s house; all other stuff is kept in the network. With more bandwidth available, customers’ options are less constrained by the size of the pipe leading into their homes.
The Most Popular IPTV Service Providers
IPTV providers range widely from huge corporations like Netflix, Google, Apple, and Microsoft to large network operators like Verizon with its FiOS video services to Sony, which also provides video streaming services via smart TVs and internet-enabled devices, and AT&T. Major IPTV providers that are more examples include Roku, Hulu, and YouTube, Amazing TV, FalconTV, SelectTV, Best Cast TV, Comstar.tv, and Xtreme HD IPTV are a few further well-known IPTV providers.
A wide range of smaller or specialized businesses that occasionally specialize in particular sorts of material delivered over a broadband IP connection are also IPTV providers. Here is a list of some extra ITPV options:
- Apollo TV Group
- Iconic Streams
- King TV
- Necro IPTV and many more
Will IPTV Alter How We Watch Television?
When they can obtain the rights, services like Netflix and Hulu offer a ton of TV series, and video on demand is expanding swiftly. The other IPTV forms, which have the most potential to alter how people watch TV, have not yet gained any traction. Catch-up TV is growing in acceptance.
Is IPTV Becoming More Popular?
There are a lot of things to keep care of because there are so many various suppliers, formats, and available pirated content. But there’s no denying that IPTV will gain more and more traction. By 2025, the market, according to Grand View Research, will be valued more than $117 billion.
Industry Statistics for IPTV
Multimedia Research Group (MRG) estimates that in 2008, there were 21.3 million IPTV users as opposed to the 1 million it predicted in its most recent forecast in late 2008, and that number is expected to rise from 26.9 million in 2009 to over 81 million in 2013. CapEx revenue plus service revenue for the last mile will increase from US$9.7 billion in 2009 to US$25.6 billion in 2013.
Many innovations are surfacing as the IPTV business evolves, including Service Providers using Over-the-Top Video applications to expand their video-on-demand selections. Growth is also facilitated by technological advancements like DVRs, HD programming, MPEG-4/H.264, and first-rate system integration.
There are 685 companies deploying IPTV services globally. While there are more Service Providers now than there were in the last report, some of them have also been eliminated since they either stopped offering IPTV services, had duplicates, or had merged with another business.
The ROW category, which increased from 64 companies to 84, experienced the most growth.
Countries like Colombia, Qatar, the United Arab Emirates, Montenegro, and the Russian Federation have experienced new growth in their operations; the ROW region, with a 29% CAGR from 2009 to 2013, will be among the fastest-growing markets.
