What is the role of television in your life?

Television is my tool to kill boredom, I watch TV when I have nothing to do, it brings me a lot of joy.

When I'm not happy and bored, it's to vent my bad feelings**, and I can make myself happy through a comedy TV series.

For me, the role of TV is the role of screen projection. Many times, when I feel that watching movies on my mobile phone is not enjoyable, I will use the screen to watch movies on the TV by projecting the screen.

I still watch TV often, especially when eating, TV is an entertainment tool in life, it doesn't need to be hard or charged, and I can watch it when I turn it on at any time.

I only watch TV occasionally now, but not often. The role of television in my life is to pass the time when I am bored.

I've been watching TV all the time, and the role is to sit together as a family to watch some variety shows, or to learn about some news events.

Nowadays, sometimes when I am bored, I will choose to watch TV, TV is to pass the time in my life, or to learn some news.

I rarely watch TV now, TV in my life is just to watch it during the Spring Festival Gala, sometimes turning on the TV can enliven the atmosphere at home.

I feel that the left and right sides of the TV are still very large, for example, when watching football, it is much more comfortable to watch on TV than on mobile phones.

I still watch TV, and the TV plays a very big role in my life, and after we have dinner as a family, we sit in front of the TV and watch TV together, which is the happiest time for us.

Television has played a role in my life to add to the fun.

For young people, TV has now become a dispensable home appliance, but for middle-aged and elderly people, TV is still the main way for people to be entertained.

With the popularity of the Internet and the advent of smartphones, the importance of television in our lives has gradually decreased, and in my life TV is usually just a decoration.

When I was in junior high school, I stopped watching TV because it was a waste of time, and TV was just a decoration in my life.

Like a radio, the effect is hypnosis.

I don't watch much TV now, and TV is a dispensable thing in my life because I have it on my phone.

1 The effects of watching TV on the human body Let's take a look at the effects of our favorite televisions. 1. Watching TV during meals affects appetite. When watching TV during meals, people tend to focus on TV and ignore the taste of food, so that the appetite that has already appeared is reduced or disappeared due to the inhibition of TV, and malnutrition will occur over time.

Solution: Look at it after eating, of course, whatever. 2. Watching soap operas lowers people's IQ Joshua of the City University of New York Brooklyn 6 1 Dr. Fogel argues that there is a connection between the choice of television programs and the level of intelligence (- especially soap operas.

In other words, watching "Sister Idler" often will affect IQ. Solution: Watch more sports competitions or knowledge programs, such as "Hundred Lectures" 3. Radiation Needless to say, electromagnetic waves of different wavelengths and frequencies will form an electronic fog that affects people's nervous system and physiological functions.

Electromagnetic waves are extremely penetrating and penetrate deep into the tissues and organs of the body. Solution: From a distance, 4-5 meters is more appropriate.

At the same time, you can choose TVs with relatively low radiation,Such as Skyworth、Konka、Changhong and other TV brands,There are corresponding health products。 4. Color change The basic principle is the same as above, constantly changing colors will make people nervous, and even affect people's appearance, making people easy to age. Workaround:

Watch less TV,Or watch TV with better color processing,In view of my consistent principle of boycotting Japanese products,I recommend domestic TV,Skyworth"Screen change"Technology、HisenseACMChe color optimization technology、Konka's CCNC color contrast lossless technology,It's all good,Among them, Skyworth's"Screen change"Technology is said to be internationally leading。 Of course, these are all for flat-screen TVs. 5. Teenagers watching TV all day long affect their personality and are prone to autism and even violent tendencies.

Solution: Participate in more physical activities, play basketball, football, running, even playing cards. 6. Watching TV for a long time is easy to lose kidneys Sitting, lying down, few people stand to watch TV, and the legs have been curled up.

Especially for the white-collar workers who work in the enterprise now, they have been busy in front of the computer for a day, if they go home or try to relax and watch TV, in the long run, the overall blood of the person will not be smooth, and it will be a matter of time before kidney deficiency and cervical spondylosis are induced. Solution: Play something else.

Television** plays an important role in improving the country's cultural soft power.

Television is an important part of the country's cultural soft power. Television is one of the greatest inventions and creations of mankind in the 20th century, and it is currently the communication carrier with the most extensive dissemination, the most ideal communication effect and the most significant social impact in the world.

According to the United Nations Human Development Report 2002, in 2001, there were 250 television sets per 1,000 people out of about 100 million people in the world, with an average of one television set for every 4 people, and the total number of television sets in the world exceeded 1.5 billion. Television has been deeply integrated into the economic, political, cultural, social and other fields of various countries, and has a wide and profound impact on people's daily life, interpersonal communication, social activities and cultural exchanges.

Television signal transmission mode The long-distance transmission of television programs adopts communication satellite circuits. Transmission between countries and regions within the country or geographically border, using microwave lines. For short-distance program transmission from the TV center to the microwave station and the earth station, coaxial cables are mostly used.

The use of microwave lines and satellite circuits to transmit television programs must use frequency modulation technology, that is, the ** signal with 0 6 MHz bandwidth is modulated by frequency modulation to the 70 MHz or 140 MHz intermediate frequency, and then mixed with the microwave frequency, after amplification, emitted by a high-increase intensity antenna; And transmitted to the remote terminal station through the microwave relay station or satellite ** device. At the end station, the signal is received by the antenna, and it is restored to the original signal after amplification, frequency conversion and frequency discrimination.

Transmission of TV accompaniment signals.

The transmission of TV sound signal The TV sound transmission with microwave lines or satellite circuits mostly adopts the subcarrier frequency mode. The microwave line can transmit 1 4 channels with sound slag and lack of huai, and the 4 accompanying frequencies are selected from the megahertz outside the ** band, one every 500 kHz or so; For satellite circuits, one of the two frequencies or megahertz is chosen.

A new way to deliver TV sound.

The new way to transmit TV accompaniment is to change the analog signal of the accompaniment into a pulse modulation signal, and then insert it into the line scan or field scan during the sweep and blanking period. The effect of the insertion line blanking period is better.

Digital Transmission. Digital Transmission of TV Signals The TV signal is digitized first, then keyed modulated and transmitted. The digital transmission quality of TV signals is high, especially suitable for transmission with optical cables.
