When you watch TV drag progress bars or high-definition online resources, whether you often encounter a few seconds to buffer over, or even stuck in the situation, these few seconds of Caton waiting, to be honest, quite disturbing, with mobile phones or tablets to watch videos but will not be like this.
Generally at this time, I will go to lenovo, is not my own WiFi is not powerful, or blame the operator, spend thousands of dollars a year to pay the network fee, how to pull the crotch.
In fact, the cause of this phenomenon, in addition to the factors of network equipment, as well as the tv short-distance transmission performance, simply put, is that the TV itself WiFi is not powerful, then what is the inside story, today there is a difference from the previous traditional horizontal evaluation, will start from the user perception is not strong but affects the daily experience of the point.
This issue of TV horizontal reviews mainly focused on the fierce fight below 3000 yuan price range, the four selections are 65 inches, respectively, Xiaomi EA, Skyworth A3, Glory Smart Screen X2, Hisense E3G series, because of the price and cost, the best-selling model of the running volume is not as crazy as the flagship TV, can do everything, that manufacturers will make trade-offs in which aspects, and in addition to the panel size chip, what hidden differences behind it can affect the user's experience.
For example, the old growth talk of the boot advertisement, 4 TVs only glory is no boot advertising (Skyworth can occasionally encounter advertisements) in comparison will not say that their money is spent, but also hard to see the advertisement, only hope that the industry clear stream can be more and more bar, let's first look at the differences in the four bits of hardware.
The processing chips of the four TVs are all highly energy-efficient Cortex-A series, the chips used by Skyworth A3 with higher prices are the best, the glory smart screen X2 and Hai credit are A53, Xiaomi EA is second, the memory aspect of Xiaomi EA and Hisense E3G are consistent, are 1.5GB storage + 8GB configuration, Glory smart screen X2 and Skyworth A3 are 2 + 16GB, everyone is enough to watch blockbusters, will not be stuck, and the gap between running is not large.
And the tv short-distance transmission performance mentioned earlier, the best configuration is the Honor Smart Screen X2, the other 3 networks only support 2.4GHz, and the Honor Smart Screen X2 uses the MT7668AU chip, which supports the higher rate of 802.11ac protocol WIFI5, that is, it can use the 2.4GHz + 5GHz dual frequency band, although it is a 2 * 2MIMO antenna, but the paper parameters are also much stronger than the other three players, can support DBDC dual-frequency concurrent processing, With routing and network speed not being bottlenecks, how much difference will the short-range transmission performance of these four bits be?
Each product we measure 5 times to take the average, in the absence of obvious occlusion, the best network speed under the 2.4GHz network is Skyworth A3, Honor Smart Screen X2 followed by, Xiaomi EA and Hisense E3G are only about half of the former network speed, less than the speed of the mobile phone 4G network, and Honor Smart Screen X2 switched to the 5GHz band, the average network speed is close to double, reaching an average of 22MB/s, at this rate, even very high-definition online video resources, is not a problem.
But want to smoothly solve the response speed of online video, not only to improve the network speed throughput can be, but also to see the delay and packet loss rate of TV short-distance transmission, such as in the transmission, this sudden cliff-like decline in the speed curve, will cause online video loading slow or caton for a few seconds, and even have to exit the video reload, and the glory smart screen X2, Skyworth A3 use better chips, more antennas, as far as possible to strengthen their own short-distance transmission performance, It is to further avoid or reduce the stuttering experience caused by the poor performance of this short-distance transmission.
After adding a wall for testing, the results are more "touching", Xiaomi's average network speed hit a 50% discount, others are more tragic than the waist chop, Hisense only has a network speed of more than 1m, used to see a domestic fake 1080P are a bit difficult, but there are also unexpected situations, glory wisdom screen X2 2.4GHz through the wall network speed compared to the 5GHz frequency band, attenuation is very strong, but also specially tested several times, the results are still the same, the next time there is time to study it again.
The difference in short-range transmission performance of the TV is believed to be understood, but only one wall can not reflect the full hidden difference, even Bluetooth can affect the performance of the TV network, do you believe it?
4 TVs only Xiaomi and Honor equipped with Bluetooth chips, but Xiaomi's Bluetooth protocol is version 4.2, and Honor is relatively new 5.0, while honor smart screen X2 also configures Bluetooth with a separate antenna to avoid interference when sharing with Wi-Fi.
Honor smart screen X2 when using Bluetooth, the network speed is basically unchanged, and Xiaomi network speed directly waist cut, this time the delay and packet loss rate will also increase, this kind of user daily can not touch, can not see the hidden difference, will not be written in the product shopping guide details page, but will affect the smooth experience of users when using, although both have Bluetooth, but in the connection of Bluetooth speakers or Bluetooth headphones, the delay is different.
I also did a small experiment, playing a test video, through the real-time post-video slow playback, you can observe that the actual picture of Xiaomi and the sound emitted by the Bluetooth speaker have a delay of about 870 milliseconds, and the glory delay is controlled at about 460 milliseconds.
Because of the difference in Bluetooth delay, when watching some fast-paced or clip card point videos, you will feel that the sound and picture are not synchronized, of course, just like the boot advertisement, not everyone will skip, not all users will use Bluetooth, but there is always better than nothing.
We just dissected this hidden difference of the manufacturer this time to tell you, since it is a TV horizontal evaluation, naturally it is inevitable to compare the picture quality, here we put the measured values of 4 TVs out, but the parameters do not represent everything, but also depends on the manufacturer's adjustment plan, the specific picture quality comparison analysis or in the video to watch more intuitively.
There is also no contrast and no harm to the sound effects, sound configuration and support of the decoding I also listed in the table to everyone, welcome to watch the video in the actual recording comparison, wear headphones The difference will be more obvious.
This horizontal review we spent a lot of time to talk about some hidden differences that will affect the user experience, as for how to choose, each audience psychology has its own focus, manufacturers also have their own product positioning of the trade-offs, we just put some daily difficult to perceive or perceive the inconspicuous places on the table to tell everyone, let more people know that tv In addition to buying a panel, there are many places and experiences that are closely related, and constantly motivate manufacturers to compete to improve their own products. Maybe one day it will really realize that all TVs will not start advertising!
