Many friends who have just come into contact with TV boxes are a little confused about some TV box terms and it is difficult to understand what they mean. Like what RAM, ROM, or what is the soft solution, hard solution, or what the brush machine, upgrade, and what the licensee is and so on. It's very confusing, but TV box novices don't have to worry anymore. Today, the author puts together these terms and explains them to make you an instant TV box. There is no need to be confused by these TV box terms. Then the interested friends hurried to learn about it with the author.
RAM and ROM
The RAM is a random memory and is an internal memory that directly exchanges data with the CPU, also called main memory. It can be read and written at any time, and it is very fast, usually as a temporary data storage medium for operating systems or other running programs. This type of memory loses its memory content when it is powered off, so it is mainly used for storing short-term programs.
In fact, simply comparing it to a computer, RAM is the equivalent of the memory used by the computer. (Actually, RAM is RAM)
The ROM is an abbreviation of read-only memory, and is a solid-state semiconductor memory that can only read data stored in advance. Its characteristic is that once the data is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not require constant data changes, and the data does not disappear because the power is turned off.
Generally speaking, ROM is equivalent to the hard disk capacity in the computer. Of course, this is only equivalent because ROM and hard disk belong to two different types of memory.
Generally speaking, RAM is the running memory of the machine. The size and capacity affect the overall running speed of the machine. The ROM is the internal storage space provided by the machine. The size of the RAM affects the software installation quantity and data storage of the user on the machine. the amount.
Soft solutions and hard solutions
Soft solutions and hard solutions can be understood as two video viewing modes. The speed of soft solutions makes the video playback smoother, but at the expense of quality, the hard solution is the pursuit of picture quality, but smooth playback. There must be some degree of influence and a larger network width is needed. If the network status is not good, the user needs to select the soft solution mode, and if the network is not a problem, the hard solution will provide better picture quality. Of course, if it is a local video, hard solutions will be more suitable.
High Definition (720P), Full HD (1080P) and Ultra High Definition (2160P, 4K)
720P=HD=HD 1280×720 resolution
720P is a display format that achieves a resolution of 1280 x 720 in progressive scan. Represents the sharpness of the picture.
1080P=FHD=Full HD ≈1920×1080 Resolution
1080P is a display format that achieves 1920×1080 resolution in progressive scan. Represents the sharpness of the picture. Clearness higher than 720P.
4K=QFHD=Ultra HD ≈ 3840×2160
4K resolution is a new resolution standard for digital movies and digital content. 4K provides at least 10 million pixels of display quality, and the display precision is more than 4 times 1080p. Its name derives from its lateral resolution of approximately 4000 pixels, and the 4K resolution common in the movie industry includes Full Aperture 4K (4096 x 3112), and Academy 4K (3656 x 2664).
Seven licensees
In the introduction of some of the boxes, many of the friends will find the description of authorizations such as Huada Genuine, Huada Authorization or Mango TV Licensing and so on. Consumers will inevitably be surprised. What is the significance of these authorizations? In fact, as early as 2011, the former State Administration of Radio, Film and Television issued the “No. 181 Document†stipulating that whether it is a smart TV or a smart TV box, as long as it is connected to the Internet, it must cooperate with the integrated broadcast control licensee to conduct content copyright cooperation before it can have TV copyright video resources are injected into the integrated broadcast control platform.
At present, only seven companies in the country have obtained licenses. They are 1: CNTV, 2: BesTV, 3: Hua Digital Media, 4: Hunan Radio and TV, 5: Southern Media: 6: China Radio International, 7 : Central People's Broadcasting Station (Galaxy Internet TV). These seven companies are the licensees or licensees mentioned by TV boxes and smart TVs. Only a licensed TV box is a legitimate regular product.
Brush, upgrade, ROOT
Brush machine
Brush is actually equivalent to the computer's redo system, the internal data information will disappear, so the user is best to back up the device before selecting the flash machine. If you perform the flashing operation, different systems will be installed on the Android device, and the system boot program will be replaced. Therefore, there are certain risks in the flashing. If the system bootstrap program error or mismatch occurs, the device will not start properly.
upgrade
In fact, the upgrade here is an ordinary system upgrade. The contents of its upgrade are mostly TV boxes and the official release of mobile phones. Some automatically identify upgrades for the system, while others require manual confirmation by the user. These will all improve on Android devices. Of course, some manufacturers also publish the upgrade package on the official website for users to download and install. Most of the upgrade systems have been released by manufacturers, or new features have been added, or certain maintenance fixes have been made to certain unstable places in the previous version. The system upgrade will not affect the original data of the machine. After the upgrade, the original data information still exists.
ROOT
ROOT is actually the name of the super user in the Android system. It has all the permissions in the system and can clean the system in depth. The process can be started or stopped, and some of the machines' own built-in systems can be deleted. ROOT, which is commonly referred to by people, is to obtain a ROOT account and let the mobile phone be under the highest authority. The advantage is that the system can be deep-cleaned to make the machine run more smoothly. Of course ROOT also has a certain risk, because having a ROOT account, in case of carelessness, may cause the system files to be deleted, resulting in the machine can not function properly. In fact, ROOT is equivalent to we usually use the Administrator account in the windows system.
Interface section
HDMI
The HDMI interface is the most recent interface. It uses the same digital signal transmission as DVI, but the difference is that the HDMI interface not only can provide all-digital video signals, but also can transmit audio at the same time. It's as if it's back to a wired RF interface, but it's just different. Using all-digital signal transmission doesn't cause video and audio interference like RF to cause poor picture quality.
USB
Universal Serial Bus (USB) is a serial bus standard for connecting external devices. USB20D is widely used on computers, but it can also be used on set-top boxes and game consoles, supplementing the standard On-The-Go ( OTG) makes it possible to exchange data directly between portable devices.
Micro USB
Micro USB is a portable version of the USB 2.0 standard and is smaller than the Mini USB interface used in some phones. Micro-USB supports OTG. Like Mini-USB, it is also 5pin. The unique thing about the Micro series is that they contain a stainless steel housing and it doesn't matter if it's plugged in and out of 10,000 times.
RJ45 network interface
RJ45 is a type of connector (for example: RJ11 is also a type of connector, but it is used on the phone); RJ45 is usually used for computer network data transmission, the connector's line has a straight line (12345678 corresponds to 12345678) There are two kinds of cross lines (12345678 corresponding to 36145278). Generally speaking, it is the network interface.
AV interface
The AV interface, also known as (RCARCA), can be regarded as an improved interface for TV. The appearance is very different. It is divided into 3 lines, which are: audio interface (red and white lines, composed of left and right channels) and video interface (yellow). The AV output is still a video signal that mixes luminance and chrominance, so the display device still needs to separate the luminance and color, and the decoding can be imaged. This approach will inevitably cause loss of picture quality, so the AV interface's picture quality is still not satisfactory. The connection is very simple. Simply connect the AV cable of 3 colors to the interface of the 3 colors on the TV. Of course, there are some boxes that provide a single AV interface, but don't worry, because the wire it provides must also be a type of delay, as long as the single interface is connected to the TV box, and the three-color interface is connected by color. Can be on the TV.
Network disk and cloud disk
netdisc
Network disk, also known as network U disk, network disk, is an online storage service launched by the Internet company, providing users with file storage, access, backup, sharing and other file management functions. Users can think of the network disk as a hard disk or U disk placed on the network. Whether you are at home, in the workplace or anywhere else, as long as you are connected to the Internet, you can manage and edit the files on the network disk. Do not need to carry, but not afraid of loss.
Cloud disk
The cloud disk is an Internet storage tool. The cloud disk is a product of the Internet cloud technology. It provides information, storage, reading, and download services for businesses and individuals through the Internet. With security and stability, mass storage features.
In fact, cloud disk is also a kind of network disk, but after the rise of the cloud technology, it has made some improvements in the function of the basic network disk, increased sharing and other functions, so that network disk has more practicality. Currently the more well-known cloud disk and network disk are Baidu cloud disk (Baidu network disk), 360 cloud disk, Jinshan fast disk, fast enough disk, micro cloud and so on.
System section
Android system
Android is the name of open source mobile operating system based on Linux platform announced by Google on November 5, 2007. The platform is composed of operating system, middleware, user interface and application software. Is widely used in smart phones, tablet PCs, TV boxes and smart TV. Most TV boxes currently use the Android operating system.
Ios system
iOS is a mobile operating system developed by Apple. Originally designed for the iPhone, it was later applied to iPod touch, iPad, and Apple TV. Currently, it is only available on Apple devices. At present, the apple tv3 TV box also uses the ios system.
Aliyun OS System
Alibaba Cloud OS is Alibaba Group's smart phone operating system. It is based on the experience accumulated in Alibaba Group's e-commerce field and a powerful cloud computing platform based on LINUX development. Has been applied to the TV box above, and at the same time such as Templar, Infinik, Lynx Box, Jieke and other brands of TV boxes are using Aliyun OS system.
Many users think that Alibaba Cloud OS is based on Android system development, but some users believe that Alibaba Cloud OS system is an authentic domestic system and is based on Linux development. It should be a "brother" relationship with Android, not "Father and son" relationship. At the moment, the author is not able to define the definition, and it is entirely up to you to judge it.
Broadband, speed and WiFi
Broadband
Broadband is currently formed in the public's perception with the network. In fact, broadband is not strictly defined. Generally, the upper limit of dial-up rate is 56 Kbps, and 56 Kbps and below are called “narrow-bandâ€. The access method is classified as "broadband." At present, both the home network and the office network already belong to the category of broadband.
Speed
Network speed is referred to as network speed. The higher the speed, the faster the download speed and the shorter the time it takes to open a web page. The dial-up Internet access speed is 45.4K, and the broadband speed is 512K, 1M, 1.5M, 2M, 4M, etc. The conversion unit is 1M=1024K, 1G=1024M.
WiFi
WiFi is wireless broadband, also known as wireless network, which can realize wireless Internet access for personal computers, mobile phones, tablet computers, and TV boxes. Actually, it converts wired network signals into wireless signals, and uses wireless routers to support computers, mobile phones, and tablets that support their technology. Currently widely used in the home, wireless routers have become almost a must-have for the home.
APP with APK
APP
APP is all applications that can be used on mobile devices to meet people’s needs for consulting, shopping, social networking, entertainment, and search. Applicable platforms are IO, Android, WP, and Blackberry. A lot of friends mistakenly think of their apps as Apple-specific apps because of the name of the app. Actually, this is not the case.
APK
APK is the abbreviation of Android Package, which is the Android installation package (apk). APK is a file format like Symbian Sis or Sisx. It can be installed by transferring the APK file directly to an Android emulator or Android phone.
Many people misunderstand APK as an APP application for the Android system. In fact, they are an Android system installation package, and the other one is the real application. Just like installing a package to a computer, clicking on an installation package will only install the program, and clicking on a program will enter the corresponding program.
3D
3D playback
Current mainstream 3D modes supported by smart TVs and TV boxes include shuttered 3D and polarized 3D. According to these two technologies, the video formats introduced are divided into upper and lower split screens, and left and right split screen formats. The red-blue 3D movies are basically out of the 3D stage because they hurt their eyes too much.
Shutter 3D TV
Shutter-type 3D TVs use shutter-type 3D technology and are used with active shutter 3D glasses. This kind of 3D technology is most widely used on TVs and projectors. It has relatively large resources and excellent image effects. It is highly recommended and adopted by many manufacturers, but its matching 3D glasses are expensive.
The active shutter 3D glasses are heavy, and they may feel uncomfortable to wear for a long time. At the same time, they need to be charged and the like, which is troublesome to use. And there will be a certain amount of flicker, all of which determine the shutter 3D TV is not suitable for a long time to watch. However, the shutter-type 3D technology is very effective. When the screen is facing the screen, the 3D effect of the image is clear and distinct, and the image quality is outstanding.
Polarized 3D TV
Polarized 3D TVs use polarized 3D technology and use passive polarized glasses. Polarized 3D technology has better image quality than color-difference, and the cost of glasses is not too high. This technology is used in many cinemas, but it has certain requirements for the brightness of display devices.
Polarized 3D gives people the feeling of not flickering, while the eyes are lighter for the user to wear for a long time, and suitable for users to watch at a distance, if too close to the screen will have a sawtooth, but not in the middle of the TV, 3D effect There will be some weakening. At the same time, the picture quality is not too outstanding.
In general, polarized 3D TVs are suitable for long-term use, and users who care about the quality of the flash do not care about their choice. The shutter-type 3D TV is suitable for people who do not watch 3D movies for a long time, and who cares about the quality of the flashing users. Currently on the market, Changhong, LG, Konka, TCL, Hisense, Skyworth and other brand TV products are mainly polarized 3D TVs. Samsung, Panasonic, Sony, Haier, Sharp and other brands are mostly shutter 3D TV products. It can be seen that currently domestically produced TVs use polarized 3D technology, while foreign countries use shuttered 3D technology. Therefore, in the price shutter 3D TV also need expensive polarized 3D TV some.
