Why Choose Ultra TV?

IP television is built on the data transmission technology adopted on the open Internet. The difference lies in the fact that:

• IPTV is a closed system, the provider of which provides a number of services to subscribers to provide access to media content. One of the reasons for the closed nature of the system is the need for copyright protection.
• Content is provided as a package of radio and TV channels. For services outside the package, a separate fee will be charged.
• The range and quality of services depends on the configuration of the provider’s head server and set-top box decoder on the user’s side.

Conventionally, IPTV can be compared with cable TV, but IPTV technology has added the ability to connect IP telephony and / or the Internet via one incoming cable, as well as use three types of transmission: Unicast; Broadcast and Multicast for increased system flexibility.

How does IPTV work?

The process of forming program packages is carried out at the IPTV head station using satellite and / or wire communication. At the same time, agreements are concluded with content owners (content providers), which are all UK, Irish, USA & Canadian or regional TV channels, owners of film libraries and foreign satellite TV and radio channels. The head server accepts the paid channels, recodes them into its own encryption system and sends them to the clients by the appropriate type of transmission through one or more routers of the distribution network. Further routing is performed by border routers (hubs) of the core network. IPTV service provides live broadcast of the corresponding channel with signal processing delay.

Unicast

The unicast type of transmission provides for the service of a specific user. With a large number of clients, the load on transport networks, server and routers increases. It is used in the VoD (Video on Demand) format – individual services or by ordering individual channels, programs or films.

Broadcast

The broadcast type of transmission organization ensures that one packet is shown to all users. The package includes popular news, sports and other channels with a variety of specializations. To determine the number of users viewing specific channels, there is a content management system on the head server that analyzes traffic and generates an IPTV playlist with a list of active channels. IPTV providers often publish free listings in order to promote their server (brand) or broadcast channel. For this reason, free playlist lists quickly lose their relevance.

The problem of using free channels from a playlist may arise on the user’s side when connecting to a TV through a set-top box (decoder), if your provider does not decode this playlist on its server. User devices with independent Internet access can use without restrictions. To do this, you need to download a file with the * .m3u extension and run it on the device using the player in accordance with your operating system and preferences. A solution to this problem is to connect the TV via Wi-Fi or via a wire with HDMI, DVI-D or DVI-I connectors to a device with an Internet connection, which is available for Smart systems or using a digital signal processing unit (active adapter).

Multicast

Multicast is based on defining a group of users who use a single packet. In this case, the head server directs one media stream to the distributor router, which is distributed to the entire user group by the border routers. Clients with a different packet receive their channel set through the same routers but with a different IP address. This arrangement reduces the load on the head server and the network distributor router.
