Definition of IPTV and Technical requirements for IPTV

Internet Protocol Television (IPTV) has become the most common name for subscription distribution systems for television or video signals using Broadband connections over the IP protocol. It is often supplied together with the Internet connection service, provided by a broadband operator on the same infrastructure but with a reserved bandwidth.

Definition of IPTV

IPTV is not a protocol in itself. IPTV or Television on the IP protocol, has been developed based on video-streaming]. This technology will evolve in the near future current television, although this requires much faster networks than the current ones, in order to guarantee quality of service.

Unlike the current situation, the provider will not broadcast its content waiting for the viewer to connect, but the content will arrive only when the client requests it. The key is in the personalization of the content for each client individually. This allows the development of Pay per view or pay per event or video on demand. The user will have a receiver device connected to his computer or to his television and through a guide he will be able to select the contents that he wishes to view or download to store in the receiver and thus be able to view them as many times as he wishes.
The programming that the companies will offer is based on both traditional channels and more specific channels on a certain topic, so that the customer can select the ones they like. In addition, sports events or premiere movies will be broadcast under pay per view, that is, paying an additional amount to the service fee to be able to see them. It is about buying the content you want to see to make a television on demand.

 

Thanks to its characteristics, IPTV will allow you to store the contents to watch them as many times as you want, but it will also allow you to pause, advance, go back, etc. as if it were a videotape or DVD.
In the advertising sector, since it is information that arrives through the internet, they could personalize their ads, so that the user with just one click can access the purchase of their products.
Additionally, it is expected within the services, search methods and restrictions, that is, parents can block certain content on IPTV that can only be shown after verification of a parental key, likewise it can search for example all programs, series or movies in which this or that author acts or that they are of this or that gender.

Technical requirements For IPTV

For IPTV to be fully developed, it is necessary to increase the speed of current connections. We can differentiate two types of channel: standard definition SDTV or high definition HDTV. For a channel of the first type it would be necessary to have a connection of 1.5 Mbps and for a channel of the second type 8 Mbps. If we have several different channels simultaneously (by having several television receivers for example) we will need more bandwidth. To this bandwidth must be added that necessary for the internet connection. We are talking about 4.5 Mbps for three SDTV channels or 11 Mbps for one HDTV and two SDTV channels. These calculations are using MPEG-4 for video compression / encoding.
IPTV needs technical values ​​to be able to provide its content without problems, the values ​​are the following:

Bandwidth: depending on the number of decoders, the speed of the internet or IP telephony (VoIP, must be higher in each case, the most common are: 4 Mbps, 7 Mbps, 8 Mbps, 10 Mbps, 12 Mbps, 14 Mbps, 16 Mbps and 18 Mbps). The fact that the bandwidth is higher, makes the ADSL line more sensitive to drops. That is, a line with a profile of 4 Mbps, if for example it has signal-to-noise values ​​of 13dB and attenuation of 40, it does not support a profile of 10 Mbps, since it causes greater attenuation and less signal-to-noise.
Signal-to-noise: greater than 13dB to guarantee the stability of the service (the higher the value, the better the service quality)
Attenuation: less than 40dB, since if it is too high, the service can have constant drops.

What does IPTV mean? Consumers are confused about the meaning of IPTV (Internet Television or “Internet Protocol Television”) according to an Accenture study of 6,000 people in Spain, the United States, the United Kingdom, France, Germany, and Italy. The report indicates that 46% of all of them – 56% in our country – do not know the term IPTV (a system through which digital quality television is broadcast over the Internet).

The study reveals the lack of knowledge, although it also reflects that IPTV services may be of interest. 30% of the sample (28% in Spain) indicate that they are interested in these services facilitating “greater access to be able to see more films”; followed by 26% (27% in Spain) who want “to be able to create their own channel to watch the programs whenever they want.”

Regarding the advantages of subscribing to an IPTV service like TOP Dog iptv (https://iptvsubscription.site/top-dog-iptv/) or HULU live TV, the largest number of respondents (55%) selected “see less advertising” (76% in Spain), followed by “the possibility of choosing special documentary-type programs” (47%) , (72% in our country).

Cost is the main barrier to the adoption of this new television, according to the study carried out by the consulting company Accenture.

55% of those surveyed indicate that they are not willing to pay an extra fee to get a leisure service even if it allows them to search for TV content, radio programs or music (46% in Spain, the lowest percentage of all the countries). Other key issues of concern and slowing down the pace of adoption have to do with security concerns (38%), such as computer viruses; the general quality of service (39%), as well as poor connections.

Young people and men are more interested

The study also points to a clear trend in all six countries: people between the ages of 25 and 34 are the most likely to adopt and pay for IPTV services. Men also show a greater interest in IPTV than women.

Although the consumer is generally very interested in the concept of IPTV, the study also indicates that providers of this type of services should focus on marketing and training for the end user.

Of the 6,030 respondents in the study conducted at the end of 2005, 1,016 were from the United States, 1,012 from the United Kingdom, 1,005 from France, 1,001 from Spain, 1,000 from Germany and 996 from Italy.
