Every morning, his aging mother went to exercise, play ball, do exercises, but never heard that she had a square dance. So when I suddenly received a call that day and asked me to help buy a square dance machine that could play video, I was really shocked. However, his aging mother needs, you have to meet is not satisfied, in addition to dancing square dance can also watch video to do gymnastics thing.
According to the information provided by his aging mother, she said that someone else is like a tablet computer, insert a video card, do not have a disc, Taobao search for a bit, this stuff is called the theater, most of them are knockoff goods. According to my understanding, it is actually a large-screen version of the earlier MP4. Finding a similar order is OK.
For me, I say that most of the products are cottage products. Searching with the keywords makes it clear that they are all "famous" brands. I bought them as a typical example. I will talk about them later. According to the size of the screen, the configuration of different, the price from dozens of to three or four hundred.
The aging mother said that the size of other people is quite suitable, bigger than ipad, check it should be 13 inches, then the entire 13-inch bar.
Just pick a first division, S85, 13 inches, selected the top version, standard 188 yuan (TF card I still trust the tea house). Yushchenko and Lynx flagship store, magical.
In order to select the top version, it goes to its life time. This kind of thing's endurance imaginary is affirmative, make a 5 fold calculation, can use 3, 4 hours, enough for the maternal two days. The top version of the legendary 1920 resolution, I feel do not fly, because I use 672,378-resolution video playback, the original size of the case, the screen length is about half of the long side of the screen, more in line with the 1280720 parameters (of course, The seller still insists on 1920.)
DVD player is a DVD drive with a DVD drive, there is no need for this.
However, buy this thing, 1280720 is enough, a lot of online video is transferred using VCD, DVD, the resolution also 672378 ah, really want to use the resolution of 19201080, after the full screen more miserable.
Packaging, looks like a special machine to watch the theater, as well as the LCD screen with careful tips. But there is no fill in this box.
There are two-dimensional codes on the packing box, keeping pace with the times. Curious, sweeping, actually still the first division service number, but "Shenzhen Entis E-commerce Co., Ltd." is what kind of bird, and Syria is not related?
Ordinary packaging, to see Wang Jie is still very kind, he loved his song as a child.
A copy of the attestation of authority was printed on the back, which caused my curiosity. Check it out.
Baidu search "Secretary", there is indeed a http:// website, search results ranked second, stronger than the cottage site, which "contact Xianke" page is blank. The latest update of company news was on 2014-5-16.
The Shenzhen Foreign Economic, Trade and Investment Corporation could not find the official website.
Shenzhen Ju-Neng Giant Digital Co., Ltd. has its official website. The website does indeed dare to introduce the official website of the official website. However, the website is more of a copycat.
Shenzhen Entis E-Commerce Co., Ltd. on WeChat, I don't know what the bird is...
For the time being, it is judged by real information on the packaging that this product is nothing more than a legally-admired brand, and it is no different from the cottage. In fact, this phenomenon is very common in Taobao many "brand-name" digital products, then the predecessors, and now it is estimated that rely on selling and selling trademarks to spend days and brush presence.
Open the package, well, the machine is protected by air cushions. No wonder there are no shock absorbers on the outside. The main accessories include the host, remote control, manual, certificate, charge head, and data cable.
God like charging head and data cable. The charging head has no standard output voltage, and it is worried that it uses an odd voltage. If it is lost, it cannot use the other heads in the home. The data cable still uses the miniUSB interface, which is not as common as MicroUSB.
Remote control, very thin, thin to press the key body is bent.
When the battery compartment is opened, it collapses. The CR1220 battery is a ghost. It is much smaller than the CR2030. Where do you want to go?
I tried to press the remote control. The buttons for playback, pause, and pause were completely unresponsive. The menu button pressed several times to respond. I was too lazy to tell the seller and throw it away.
The host, positively looking good, is relatively simple, there is no exaggeration of local gold. The legendary full-covered tempered glass is affixed with a protective film. I tried to scrape it with a nail clipper. The screen seemed to be really glassy, ​​and I couldn't even scratch it.
The row below the screen is the operation button. The number keys on the left can be used to quickly select music, enter the serial number, press the play button to start playing, suitable for video is a fixed, very familiar with the order to use later.
The main operation button is on the right.
1. Return key, equivalent to exit;
2. Movies, music, radio, press to quickly enter the mode;
3. On the song, under the song, very good understanding, long press is fast retreat, fast forward;
4. Off screen, used to turn off/on the screen display when playing video, which means you can also use the video as music to save the battery;
5. The menu is used to call up the setup menu when playing. Usually it will not be used. After all, the elderly will not normally set this up, or it will be better for us to set up the help of our children.
6. Play, is the play and pause key.
Overall, the operation is not difficult. By the way, the specification will not be read, and it is totally incomprehensible. How to feel the key? You and I are joking.
There is a bracket behind it. It is used to stand up the mainframe and the damping force is very large. It can't be said to hold back. There is also an anti-skid rubber ring on the bracket.
From this figure we can also see that there should be only one horn, the horn sounds loud, and it is not a problem if it is not too noisy.
Looking sideways, it's pretty.
The top interface area. On the far left is the mechanical volume control. This design is good. In fact, the elderly prefer to use this most traditional method, but if the knob can be bigger, it would be nice. With headphones and microphone interface, it is said that you can sing karaoke, do not underestimate these cottage products, the function that is a strong one.
U disk and TF card support these two kinds of storage, measured 16G TF card no problem, higher did not try.
The charging port is miniUSB, which supports the use while charging, but does not support using the data cable to connect the computer to the U disk.
The right is the physical switch, dial on to boot, do not play directly dial off off like.
Finally found the input voltage, but fortunately it is 5V, so that the charging head is broken and found a random one, and now each has a few idle.
The seller said that the machine is using the 18650 battery, open the battery compartment on the back, really, but still own brand. At nominal 2200 mAh, the two parallel connections are 4400 mAh. I am not afraid of false standards, quality flies on the line.
Find out my own few 18650 contrast, hell, the standard battery is longer than the non-protection board, shorter than the protection board ... ... intend to over time determine not to return, put on two of my Good battery, at least peace of mind.
The bottom of the non-slip gasket, awkward.
The back bracket can also be converted into a handle pattern, and you're going to exercise while you walk.
To give a more intuitive screen size, the long side of the screen is longer than the short side of the A4 paper. Measured, the screen diagonal 25 centimeters, is actually a 10-inch screen; machine diagonal about 34 centimeters, it really is a "13-inch" machine.
This is the main interface. The 8 functions are arranged there. It is simple and clear. Use the up and down keys to select and press to enter.
It should be noted that, in the most commonly used video playback and music modes, the battery level is not visible, and the battery level is returned to the home screen or e-book mode.
Setting the page, actually can set the volume ah, that is to say, this machine can limit the maximum volume in the settings, and then combined with the mechanical knob to adjust within the limit, not bad.
The movie mode is playing video. First, the list of videos will be listed for you to choose from.
To mention one thing, the machine will automatically enter the movie mode by default after starting up, and automatically start playing from the last played video. Should highlight the "look at the plane" feature, not bad.
Music mode, operating and playing video is similar. The right side will show the equalizer curve, progress information, and audio information.
The volume of the speaker is quite loud, although the sound quality is normal, but the playing music is not very destructive (sometimes there are some occasions when playing video).
Music supports background playback, as long as you do not change to video, radio mode, in other modes, music will be played in the background. The music mode also supports the memory function. After booting, it will start playing from the last played song. If you switch to another mode and then return to the music mode, you will start playing from the previous progress.
In the picture browsing mode, several high-resolution photographs were taken using a single-lens reflex, which can be displayed normally. It seems that the hardware performance of these products has also improved. Unlike previous MP4s, high-resolution photographs cannot be displayed.
Press the menu key to perform some basic operations in picture mode.
E-book mode, just take a txt try it, this feature should be the least used.
Radio mode. The built-in antenna of the machine does not help measuring the plugged-in headphones. Support automatic search and storage. It is strange that in the radio mode, if the screen is on, the signal is very poor and the signal is normal. So in the radio mode, the default is no operation for 3 seconds to automatically blank the screen.
File management mode. The machine supports multiple directories, anyhow you set the directory (but I haven't tried a multi-level directory), and it will go to search for the supported format after entering the corresponding mode. This function is still very necessary, I can store things in separate directories for later management. I remember using a digital product before, but the file can only be placed in the root directory and it almost crashed.
In each mode, press the Menu button to open the setup menu for that mode. Use the menu in video playback mode to make a note.
Can adjust the channel, audio track, jump progress, sequence (single, sequence, random what), screen size, display brightness, video output (the original machine on the AV-OUT jack also supports video output it) and so on. All of them have ah.
The right side is the current state. The current display is: sequential playback, brightness 50%, screen size is automatic, and file name is what.
The following is a progress bar, how much is currently playing, and how long the video is.
However, the menu's words are relatively small, so I suggest that the children first set up their parents.
The most commonly used viewing machine is the video playback function. In the end, what is the video support capability? I tried to find a few videos to try it out.
At the same time find some music, photos, txt to try it. The music, photos, and txt were introduced before the incident. The problem is not great. Still the main test video.
Square dance, aerobics, mostly found on the Internet for the FLV and MP4 format, the seller also suggested that I go to Youku, potatoes this site to download. So casually find a few square dance and aerobics in FLV and MP4 format.
In addition, I also found several AVI, MP4 (mobile video 720p), MKV (720P), RMVB (720P) to try. As mentioned earlier, many square dances and aerobics are transferred from VCDs and DVDs. The resolution is very low. If these 720P formats can be played, I believe it is enough to use.
RMVB format, resolution 1536720, 1.7GB. This picture with video parameter information is captured on a computer, the same below.
Not to mention, the play is smooth, the picture is clear and satisfactory.
Before taking a small video of the phone, MP4 format, 1280720 resolution.
Smooth play, clear picture, and satisfaction.
Online fitness, MP4 format, 672370 resolution, should be transferred from DVD.
Fluency must be no problem. But for clarity, don't look closely.
Online fitness, MP4 format, 448,328 resolution, may be transferred from the VCD.
Fluency needless to say. Clarity, I'm far from seeing it and it's uncomfortable.
Look at the character's close-ups and return to it 10 years ago.
The fierce MKV format, 1280720 resolution, is an animation.
The same playback is smooth and the picture is clear.
To a detail, 10cm from the screen, the pixels are clearly visible, no problem with the clarity of the picture.
Once again, if it is a video with poor resolution and poor picture, it would be a terrible thing on the HD screen. The two figures above are examples. So try to download high-definition video, at least have to turn DVD.
In addition, several AVI formats have been tested, and the resolutions vary from small to large. Among them, there is a small resolution image with no sound. It may be that the video encoding is quite special.
The seller said that he was using a TFT screen and tried different angles. The viewing angle was good, but he looked at the angles obliquely and the picture was still somewhat changed. The price of this screen is not too high. After all, dancing and fitness, not a group of people watching the screen around the machine (even I think, stand still so far still see the screen motion you do).
In addition, at the time of tossing, there was a phenomenon of automatic restart of crashes, and it seemed that various playback menu settings were being tested. This kind of machine is similar to the earlier MP4, and it is easy to crash. However, honest use should be fine. Quite gone.
to sum up:
advantage:
Basic functions are enough
The operation is relatively simple, and the elderly can master basic operations several times. Let his aging mother try it out for a few days, and the children will be happy to use it by setting up the machine.
Cheap, is the biggest advantage, and can even cover other shortcomings, haha. 188 yuan, 10 inch super screen, change the phone screen is not only this price right.
Disadvantages:
The main problem is that in terms of materials and workmanship, there are too many disadvantages and they are too lazy to enumerate. 188 yuan, what else do you want.
As long as we can stick to one year, it is victory.
Written in the end, ask the next value you friends, there is no good quality look at the machine recommended, the price should not be too expensive (less than 500 yuan), the operation should be simple, the screen should be about the same size. There are better machines. Who do not want to spend more money on the elderly? But don't mention ipad and I like it, price, and secondly, file management is big, and smart things come to me.
