One of the reasons that I thought I had disabled the set-top box at the beginning of the year was to be pitted. At that time, I said that a good general free upgrade to the HD station would result in an extra 300 yuan for no reason, and I decided to stop using it at one go. Now a search on the Internet, there are still a variety of Tucao was pit. Here we come to count how many people in this set-top box in the end! 
Expensive. In addition to the set-top box needs cost, every year also need to pay Cable TV costs, such as Shanghai is 23 yuan / month, which is 276 yuan / year, not counting the cost of some paid channels, if you look at 10 years, is close to 3,000 yuan. If you have more than one TV in your home, you have to buy it again! If you have one in the living room, one in the bedroom, and one in your mom and dad (don't say why so many TVs, multiple TVs can be solved You want to watch Korean dramas and your father wants to see the contradictions of the anti-Japanese drama.) Then you have to buy two more TV set-top boxes, which are almost $300, which is a lot of money.
The content is empty. Set-top boxes can only look at normal TV stations and some local stations, such as CCTV, Hunan TV stations, Jiangsu TV stations, etc., and don’t say that young people today still look at these, that is, they usually need to pay a higher price for HD. , And more than 20 high-definition stations, at the time he was foolishly flickered to do high-definition, more than a year to hand hundreds of oceans. The Internet TV box can be installed on your own TV software to watch TV stations, and you can also order your favorite TV shows and movies on your own. The content is even more than you can count.
Whatever you broadcast, you can only see what you want, but also accept endless advertising. Set-top box TV, do you want to be the master? No way! What it broadcasts, you have to accept, even if a TV drama inserts 10 advertisements you must accept!
Since the content of the set-top box is small, the cost is high, and it is still impossible to make decisions on its own, why not watch television in another way?
Smart TV
The current smart TV basically can be said to be equipped with Android operating system TV, users can install and uninstall all kinds of application software, usually download good watch software such as Tai Jie, VST, TV cat, and then put it into U disk, insert To the TV's USB interface, and then through the file management to find this software, click Install, you can use this software to watch TV. Compared to the traditional set-top boxes, it can only broadcast what you see, and the rich resources of smart TV, you can see what you want to see, and decide for yourself. And for friends who have more than one TV at home, if they are set-top boxes, they need to have one for each TV. However, smart TVs do not need to remove the cost of cable TV and save money on equipment. 
Network box
For a home TV that is not a smart TV, or a friend of a former old TV, the way to abandon a set-top box is to have a network box. Currently, some of the mainstream brands in the market include Xiaomi, Huawei, Skyworth, Haimeidi, Kaiboer, and Lynx Box. The functions are basically similar, except that the hardware, appearance, and system UI are different. The box market that could have been singing all the way, but also because of SARFT's many policies, such as pre-installed live streaming software and third-party video software, will eventually make the box become so tepid. But the wisdom of netizens is endless. Since you don't want to pre-install, then I use my U disk to install myself; you also have to make sure that I can not install U disk, such as the Lynx box after the upgrade of the yunos system A lot of third-party software, then I brush firmware, anyway, there are ways to install the software. Some netizens have used the home second-hand laptop to connect to a TV as a monitor, so you can't limit the Internet. According to different boxes will have different methods, here is not one by one introduced, there is a need to go to Baidu. 
Smart projection
Smart projection may be the TV of the future. Since the rise of intelligent micro-investment brands such as polar rice and nuts, intelligent projection has gradually entered the public view. Before the projection in everyone's impression is used only when the meeting, and now the projection can be turned into a living room to see the film weapon, instantly cast a hundred inch curtain, coupled with professional audio, there is a feeling in the cinema. With it, the TV can be no longer needed, but also the set-top box. 
Cable TV
This method is suitable for remote areas where cable TV is very expensive (before going to a small village in Yunnan, cable TV more than 1300 a year!!), or where there is no cable TV. 
However, this method is already illegal, so please use your own discretion before using it and cherish it. 
With so many ways to watch TV, do you still use set-top boxes? This pit person's TV set-top box should soon be replaced by these new ways of watching television.

The most failing and most invented invention in the 21st century - set-top box! How long can you live?
Recently I saw an article saying that the set-top box is the home appliance that consumes most power in standby mode. To tell the truth is really unexpected, because after all, I haven't used a set-top box for several years, I only saw the news that I know this fucking stuff is still there. If I had to give it a title, I think "the most failing and most invented invention in the 21st century" deserved.
