IPTV (Internet Protocol TeleVision) is the delivery of programs by streaming video data encoded as a series of IP packets. That is, instead of receiving the requested television or video over radio / satellite or cable waves, the television is connected to a broadband internet router and receives the internet signal.
IPTV service like Top Dog IPTV (https://iptvsubscription.site/top-dog-iptv/) is emerging as the trend for the future of the audio-visual world. Many broadband operators already provide this service, which is mostly included in the Triple play Internet offer. (Internet + Telephone + Television).
This system offers a complete solution for the organization to bring together television, telephone and Internet communications on a single data network, which improves communications management. The solution is based on open standards and is fully adaptable to
specifications of your need.
The definitive platform for complete and easy television management:
– Customization of the channel list
– Quick and easy creation of one or more channel lists
– Each channel list can be assigned to different users or groups of users
– TV channels can be configured as pay channels
Under the term IPTV, we group together live television, video on demand (VOD) or catchup sessions.
-Over-the-air television is provided by all ISPs today. This is grouped together in “triple-play” offers and allows the user to have basic DTT channels as well as channels formerly reserved for cable / satellite. The package taken by the individual defines the level of channels accessible by his subscription.
–Video on demand is a technique for broadcasting digital video content offered or sold by operators of fixed and mobile internet networks. Video on demand frees the customer from broadcasting schedules. On the other hand, this technology is very greedy in network resources, its evolution is linked to the increase in the bandwidth of operator networks.
-The remedial sessions follow the same principle as video on demand. The difference lies in the origin of the content. Video on demand is often a film, a documentary accessible in DVD / Blue Ray format, while the catch-up sessions allow you to view television broadcasts (Newspapers, TV magazines, etc.).
In addition to pooling architectures, IPTV makes it possible to better manage resources and extend the uses of television through:
In radio television broadcasting, all channels are sent at one time and the consumer chooses which signal they want to display on their television. With IPTV, the consumer chooses the stream to be displayed which is centralized to him at the provider. Thus only the requested flow is transmitted from the operator to the consumer.
Many services are developing around the interactivity offered by this technology. Communication is two-way, the consumer receives the video stream, but he can also make choices from the remote control. For example the consumer can buy articles from his television set, answer surveys etc…
Thanks to ever more advanced computer codecs (MPEG-2, MPEG-4 and VC-1.), IPTV can provide better picture quality at a smaller size. It is thanks to this that many operators offering IPTV make it possible to receive 1080p HD television.
The communication chain induced by IPTV can be represented in 4 elements:
– Video Converter:
This functional block individually receives the channel to be transmitted and converts it into a digital video format such as MPEG-2 (the most used format). Increasingly, providers of this service are encoding in MPEG-4 in order to be able to provide HD agreements on an identical physical medium.
After converting the video format, it is encapsulated in IP in order to transmit all the packets on the physical network.
– Provider of access to the physical IP network:
This is the element that allows Internet service providers to use the physical network to transmit data. These physical networks are most often owned by the internet service provider. If not, the Internet service provider rents links from another to transmit their data.
– Internet service provider :
This is the network between the customer’s and the Internet service provider’s central office (DSL network for example).
– User local network:
This is the network which is located behind the operator router (LiveBox, SFRBox, etc.) on the user’s own premises.
Limitations of iptv technology:
In these times when many questions arise around the anonymity of the violation of privacy on the internet, IPTV also opens fears in the sense that the operator has the vision of the channels consulted by the user since he ci by pressing the “1” button sends a request to the operator to send him channel 1.
IPTV uses the same types of data and media as the transmission of data packets over the internet. Therefore, it can happen that packet loss occurs or that packets arrive late. As a result, reception is degraded and is much more sensitive to the Internet connection speed.
