It is probably impossible to imagine a person’s life without television at the present stage. For the convenience of watching TV shows, the most non-trivial ideas are embodied in reality, starting from SMART technologies and ending with interactive TV. Are there any differences between the types of broadcasting? What are the pros and cons of television? We will try to answer these questions in the article.
Interactive tv
On the territory of the Russian Federation, they first talked about interactive television 3 years ago. Since that time, an amazing history of the development of these technologies began. All leading state providers have switched to a similar method of providing television servants. What are the pros and cons of television of this type?
- Firstly, the main advantage of such broadcasting is that users are offered a wide range of functionalities that will make watching their favorite shows enjoyable and convenient. We are talking about such user-defined functions as rewinding, recording and pausing any television programs. In addition, it is possible to display the program guide on the TV screen, and also provides integration with the most popular social networks.
- Secondly, a wide technical potential. The image is striking in its quality, especially when broadcasting HD-channels. The picture is clear, does not have glare or other interference.
- Thirdly, it is possible to conduct interactive television even in the absence of a standard connection. In this case, providers use a telephone line (ADSL technology).
Cons of Interactive TV
Speaking about the pros and cons of television, it should be noted and obvious disadvantages.
- To broadcast channels, a special STB-box is required. Its cost is from 3 thousand rubles. In some cases, the price reaches 10 thousand, which depends on the provider. It is not possible to purchase at a store at a lower cost. The only thing that operators can offer is the purchase of equipment in installments for 12, 24 or 36 months. In this case, the cost of the prefix will be included in the monthly payment - from 100 rubles and above.
- To control the console, an additional remote control is provided, which may not be convenient for everyone.
- If the telephone line has low bandwidth, there is a risk that the connection request will be rejected.
Satellite television
Satellite television is very popular among Russian residents. Today, there are a large number of operators providing such a service, ranging from Tricolor TV to NTV Plus. What are the pros and cons of satellite television?
- Availability. If interactive TV can be connected under certain conditions, then satellite TV is available to each user without restrictions.
- A huge set of channels. The audience has over 100 channels to choose from, and there is an additional opportunity to connect thematic catalogs.
- Clear picture, especially when connected to HD-TV.
Cons of satellite TV
Modern television, its pros and cons as a whole converge, regardless of data transmission technologies. However, satellite TV has slightly different flaws. So, it should be said that in bad weather, during a thunderstorm or overcast, a signal from a satellite may disappear. This becomes the reason that under such conditions it is impossible to watch TV channels. This problem is solved independently, after the completion of adverse weather conditions.
Talking about satellite and cable television, the pros and cons of these broadcasting methods, one should not forget about such a common drawback as the disappearance of channels from the usual list or their coding. This problem is solved by reconfiguring the signal frequency.
Digital television
To date, a program has been launched in the Russian Federation that aims to replace the analog signal with digital TV. Owners of a TV in which a digital receiver is installed can view up to 20 channels through a conventional antenna. For those who do not have such an opportunity, special equipment was developed - a receiver. After installing this device, even in the most remote corners of Russia, it becomes possible to watch your favorite channels. The pros and cons of this type of television are as follows:
- The image has high resolution and good definition.
- When watching TV channels there is no interference.
- Lack of monthly fee. 20 channels are provided completely free of charge, regardless of the region of viewing.
- Easy setup, as well as the absence of additional operating conditions.
Cons of Digital TV
Speaking about the pros and cons of digital television, special attention should be paid to the disadvantages of this technology.
- In some cases, friezes may appear. This problem is due to signal degradation or lightning interference.
- Limitedness. Digital TV offers the ability to watch only 20 channels for free. All that is above this is provided for a certain monthly subscription fee after the purchase of special equipment.
- Scattered ratio. It is often seen that when viewing certain TV channels, vertical or horizontal frames appear on the sides. This is due to the fact that in the territory of the Russian Federation there are no uniform broadcasting parameters. Thus, some channels are broadcast in 16: 9 resolution, and some in a format typical of old equipment (4: 3).
