So how can children watch TV?
Does TV have any effect on a child's health, development and cognitive ability? Shouldn't children from 3 years old watch TV? What influence does TV bring to their lives?
There are now two very different perspectives:
proposition view:
Watching TV is one of the effective ways of early childhood education.
1. Television can promote children's language development and expand their vocabulary. The period of infants and young children is the period of children's language acquisition, television pronunciation standards, sounding music, and vivid pictures, which can better attract children to imitate and understand, thus improving their language skills.
2. Watch TV to develop children's brains. Infants and young children watching TV will also try to understand and understand the picture, which helps the development of the brain.
3. Television as an intermediary can broaden children’s knowledge and allow them to better relate to society. Television allows them to intuitively recognize a variety of things that have never been touched: various social roles, animals, fish, birds, and even ancient dinosaurs, for a wide range of information.
Anti-party view:
1, the child's vision is harmful, easy to cause strabismus.
When adults watch TV, they either hold their children or place their babies alongside their cradle. As infants and young children are attracted by the sound of television, they tend to look sideways at TV. If you stay in the same position, it will naturally cause strabismus. Slightly older children watch TV for too long and their eyesight will be fatigued. In order to see more clearly, sometimes they will appear in a gimmick position. When they take a long time, they will squint.
2, resulting in myopia, astigmatism and other eye damage.
The visual regulation function of infants and young children is not yet fully developed. For the direct stimulation of strong light, it is difficult to adjust and adapt to vision. When babies are watching TV, they especially like to watch programs with frequent flashing screens and strong color irritations. For example, adults rarely can successfully pull their children off the TV when they watch an advertisement. Infants and young children, especially children under 2 years of age, their refraction, eye position and other regulatory systems are not yet well-developed, watching television is certainly not good for their vision development.
3, long-term watching TV will appear "TV autism"
There have been expert analysis: The father of comparative behaviors Dr. Ken Z. Lorenz believes that the learning experience (light, sound learning experience) that people see and hear within six months after birth will become a matter of growth. Foundation. If the baby is subjected to strong light and sound stimulation too early, the baby's brain will respond to mechanical sounds and will not respond to the sounds of mothers and other relatives, which is a major cause of autism.
He believes that television will have a complete destructive effect on children whose minds are still developing, especially children 0, 1, and 2.
Television will deprive children of their thinking power, because watching television needs only the child's passive attention, and children will no longer have a brain to use in the cognitive learning of watching TV. Children who are addicted to television have a lack of initiative in their lives. They pay too much attention to television and let them ignore their toys and children. They watch TV programs that are not suitable for them and they do not want to communicate with other people. TV autism."
4. TV may cause obesity in children.
Some babies like to watch TV while eating, parents also found that the baby will be more honest when eating, simply let him eat while watching, and sometimes even turn on the TV when the baby eats. The baby's mind is all on the TV, often do not know when the stomach is full, will eat too much, leading to obesity; at the same time, this also affects the baby's digestion, likely to cause gastrointestinal disorders.
5. TV may cause arrhythmias in children.
Pediatric clinics report that more and more children have physical abnormalities because they watch too much TV. Many children do not have structural heart disease but they have arrhythmias. The study found that these children have one thing in common: they watch TV more than three hours a day. Continue for more than 2 weeks.
Experts believe that children, especially infants and young children, watching television for a long time without choice will lead to more than 50 kinds of diseases, such as hyperactivity, headache, abdominal pain, sleep disorders, anorexia, enuresis, phobias, and skin rash.
How to minimize the damage to the TV?
Watching TV has many harmful things. However, in this modern society, how can children be completely isolated from TV? Who can not have TV? If parents can't watch TV and stay away from TV, then what adults can do is to minimize this amount of harm.
Give you some reasonable suggestions:
1, eat more foods containing vitamin A, mainly animal animal liver, fish, seafood, butter and eggs and other animal foods.
2. Pay attention to the posture and distance of children watching TV. The distance from the screen to the screen is generally 4-6 times the diagonal distance of the screen. The center position of the TV screen should be slightly lower than the baby's sight line or the line-of-sight to avoid eye fatigue.
3, the brightness of the TV should be moderate. If the light is too bright, the pupil will shrink, making the adjustment nervous. If you turn off the light and watch TV, the brightness of the screen and the surrounding darkness will be too strong, which will easily damage the eyes. It is best to install an 8 watt lamp indoors, corresponding to the TV screen.
4, control the volume of the TV. Infants and young children have very delicate auditory organs. Listening to loud sounds for a long time can paralyze children's hearing and reduce their hearing sensitivity.
5, the remote control in adult hands. Children before the age of 3 are best to control the time of television, not more than 15 minutes each time; resolutely stop the baby while watching TV while eating; watching television time is not set after a meal, the baby is full and can cause obesity; Do not watch TV before, so as not to stimulate your baby's brain and make it difficult to fall asleep. Choosing knowledge for the baby is more fun, which is conducive to the development of children's healthy and upward-personality programs; and it prevents TV programs such as murder, terror, and martial arts from stimulating children's nerves, making children frightened, and making nightmares.
6. Watch TV with your child. In the process of watching, inspire children to think and ask their children questions or answer their questions at any time. After watching, they watch the content to ask questions to the children, thereby enhancing their observation, attention and memory.
7. In fact, children do not like to watch TV as we imagine. The deeper reason why infants and young children are overly infatuated with television is because of loneliness, lack of adult companionship, and lack of beneficial activities that fill their young hunger and thirst.
In fact, there is only a one-way connection between children and television. They prefer activities that are eye-catching, hands-on, moving and inspiring imagination, such as reading, games, music, and outdoor activities.
As long as parents are willing to make arrangements and find interesting activities to enrich their lives as much as possible, soon you will find that children are not willing to watch the cold television alone. They even want to play with their parents and friends. communicate with. Give your child a chance to play with his parents' partner. Is he still willing to stay in front of the TV?
Is it good or bad for children to watch TV? Do you have any opinions or suggestions? Welcome to speak up and leave your precious opinions and share your experience.
The full name of LTE CAT is LTE UE-category, which is broken down to explain :LTE refers to 4G LTE network, UE refers to user equipment, and Category is translated as level. Smooth interpretation is the level of 4G LTE network transmission rate that user devices can support, which can also be said to be a technical standard for 4G network speed. Therefore, LTE CAT4/CAT6 means that the user device LTE network access capability level is 4 or 6.
Since the level is different, then its capabilities are certainly not the same, let's take a look at LTE CAT4/CAT6 affect what performance, respectively, what level. Simply put, LTE CAT affects the upper limit of 4G LTE uplink and downlink network speed, which is generally referred to as the maximum upload and download speed that a user device can achieve.
There are not only 4 and 6 levels in LTE CAT, but the table above is our list of currently known LTE CAT levels and the corresponding maximum transmission speed. Among them, LTE CAT4/CAT6 is also the current network transmission technology level of 4G mobile phones, while the faster CAT7 and CAT8 are still in the laboratory stage and have not been commercially developed.
Phones and chips that support LTE CAT4/CAT6
As far as the current 4G mobile phone market is concerned, most mobile phone products are CAT4 technology, and only a small number of new mobile phones use CAT6 technology, such as Huawei Honor 6, Samsung Galaxy S5 advanced version and LG G3 Cat6, and the concept of LTE CAT6 is proposed by Huawei Honor 6.
For the mobile phone LTE CAT4/CAT6 standard, it is directly linked to the mobile phone chip, or, if you know the processor of the mobile phone, you know which technology the mobile phone uses. For the current 4G mobile phone chips, only Huawei Kirin 920 and Qualcomm Snapdragon 805 processors for LTE CAT6, before this 4G chips are LTE CAT4, the future and Kirin 930, Qualcomm Snapdragon 808/810 will support LTE CAT6. Mediatek won't have LTE CAT6 chips until the second half of next year.
Qualcomm Snapdragon 805, 808, and 810 also support LTE CAT6
It is worth mentioning here that Qualcomm Snapdragon 805 and Kirin 920 are not the same in chip design, the LTE CAT6 baseband of Snapdragon 805 is an external Gobi MDM9x35, while Kirin 920 is a direct SoC integration, and the chip is integrated, this point Kirin 920 has ultra-high integration. It has certain advantages in power consumption and cost. As a leading international communications company, Huawei's strength can not be underestimated, but also the pride of our people.
The actual use value of LTE CAT6
Upload, download speed is our use of mobile Internet access the most concerned performance, but it should be clear that the LTECAT standard is the 4G transmission speed limit, and can not improve the transmission speed, in the operator's 4G network speed has not reached the next standard, simply raising the limit is meaningless. At present, the 4G networks of domestic operators are all LTE CAT4 standards, and the peak download speed is 150Mbps, but it is difficult to reach the upper limit of LTE CAT4 in practical applications, and even to reach 100Mbps is very difficult, so at this stage LTE CAT6 has no use value.
In terms of real life applications, LTE CAT6 is not as beautiful as we think. We can do a calculation, according to the formula 1MB/s=8Mbps, the maximum download speed of LTE CAT4 is 18.75MB/s, such a download speed, for 1080P video online playback has no pressure, even 4K online film source still can not occupy such a large bandwidth, So LTE CAT6 has no use either.
To sum up, LTE CAT6 does not have much use value at this stage, and the term is only a gimmick of manufacturers, until the operator 4G standard reaches LTE CAT6, I believe that LTE CAT6 equipment has long been popular. So as for whether the phone is LTE CAT4 or LTE CAT6, you don't have to care.
Is your child a TV lover? Does your child like to eat in front of the TV? Are you accustomed to using a TV to listen to children? These and other issues should all be worried now by parents. In the current family, television has become an indispensable part of children’s daily life. When parents don’t have time to deal with children who are tangled up, they usually use TV to calm them and keep them quiet on TV. . I do not know when, we found that children initially understand and take the initiative to pay attention to television. The baby about 1 year old will laugh or dance with joy when he sees something interesting. Slowly the children have learned to switch on their own. About 2 years old baby has continuous attention on TV. By the age of 3 they can identify things they are familiar with or interested in on television, show a more stable interest in certain TV screens such as animals, flowers, cartoons, etc., chant songs, make cartoons on television, etc. .
