2017 smart network set-top box should be how to choose?
First, chip select 64-bit processor
With modern people's increasingly stringent entertainment performance requirements for intelligent network set-top boxes, smart network set-top boxes carry more computational load than ever before, as mentioned above for gaming, shopping, learning, and life, especially for Android. Versions later than 5.1 (including Android 5.1) are more equipped with a 64-bit software system, so 64-bit processors should be selected when purchasing chips. Currently, the market is showing a trend of four pillars, including Hass and Jing Chen. Ruixin Micro and Ruiye.
Second, select large memory, eMMC high-speed flash memory
The memory determines the smooth running of the system and the fluency of the application running of the intelligent network set-top box. In 2017, the new smart network set-top boxes are mostly equipped with 2 GB of large memory, which is more than the popular TV-side APP. The flash memory market mainly has NAND. There are two types of flash memory and eMMC flash memory. The general set-top box NAND flash memory generally has a read speed of about 8-15 MB/s, while the eMMC read/write speed is generally 23 MB/s or higher. With the eMMC set-top box, the boot speed and APP start up are used. The speed will be greatly improved, with a smoother operating experience.
Third, the output interface is selected on demand: ordinary users to take HDMI, depth players to complete
In the purchase of intelligent network set-top boxes on the choice of interface to follow two principles: First, watch the home TV interface is HDMI or AV three-color interface to select the set-top box; second, according to personal needs to choose the richness of the interface. Now the family is generally flat-panel high-definition digital TV, for the average user an HDMI interface can transmit high-definition video and audio, simply speaking, "there is an image with sound", for film and television enthusiast players, in addition to the HDMI interface, optical fiber, coaxial It is also indispensable, and conditions permit dual HDMI output (one output video, one output audio) can also be considered, HDMI version needs to consider version 2.0, because HDMI 2.0 has a high transmission bandwidth of 18Gbps, can perfectly transmit 4K@60Hz, 4K HDR and other ultra-high-definition Blu-ray quality, in simple terms is "there is quality sound quality."
Fourth, Android version should choose 6.0 or above
In 2016, Android 5.1 dominated the year and Android 6.0 emerged. With the iteration of the update, Android 6.0 became the mainstream in 2017, and Android 7.0 began to develop. Therefore, Android 6.0 should be selected in 2017. Android 6.0 system is optimized for fluency. It allows applications to run in the background and no longer use memory. No matter if it is system control or application running, the speed is very smooth. Android version 7.0 also improves the system's redundant processing capacity from the bottom, and memory utilization. The rate can be increased by 100%, the software installation speed is increased by 75%, the operating speed is increased by 600%, and the safety performance is also improved. The HDR/WCG and full 4K core are also perfectly supported.
Fifth, a legal broadcast control platform (provided with one of the seven major Internet TV licensees)
The purchase of intelligent network set-top-box products is legally compliant, and the “Regulations for the Operation and Management of Holding Internet TV Licensing Organizations†issued by the SARFT (referred to in the industry as Article 181) mentions that there are seven legal copyrights required for smart-network set-top boxes to carry Internet TV licenses. The online video platform provided by the companies, the copyright holders of the seven Internet TV licenses are CNTV, BesTV, Huadian, Hunan Broadcasting, Southern Media, China International Radio, and the Central People's Broadcasting Station.
Sixth, (video enthusiasts) support 4K HDR, with TRUEHD and DTSHDMA genuine license
The last point is advice provided to film and television enthusiasts. With the penetration of smart network set-top boxes into hard disk players, more and more intelligent network set-top boxes support powerful local decoding functions. The current highest video format is 4K HDR with large dynamic range. The ultimate detail can be demonstrated. The audio is characterized by two high-definition audio technologies, TRUEHD and DTSHDMA, and is transmitted to the rear decoder through HDMI to achieve a maximum of 7.1 surround channels.
Comments:
In addition to the above six points, the last Xiaobian should remind everyone to pay attention to several misunderstandings during the purchase: First, buy smart network set-top boxes to buy according to personal needs and price range, do not buy expensive only buy right; Second, the smart network set-top box is not equal to the game console. It is no problem for the smooth running of 2D games. Occasionally, there will be some Caton for 3D games. Third, not all Android set-top boxes can install APPs. Some Android set-top box manufacturers want to use their own high-end products. Models distinguish the market, often without an application market, and even do not allow users to install Android APKs themselves. They can only use the APK application that comes with the system.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
Push Button Switches
The Push Button Switches, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally can be automatically reset. The Push Button Starter Switch is usually used to issue a start or stop command in the circuit to control the turning on and off of electrical coil currents such as electromagnetic starters, connectors, and relays.
The On Off Push Button Switches refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. It is a master control device with a simple structure and a wide range of applications. In the electrical automatic control circuit, used to manually send control signals to control connectors, relays, electromagnetic starters, etc.
This Pushbutton Switches is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in AC and DC voltage below 440V, the current is less than 5A in the control circuit, generally do not directly manipulate the main circuit can also be used in the interconnection circuit. In actual use, in order to prevent desperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like.
The Momentary Push Button Switch could be divided into metal push button switches and LED Light Switches and ordinary snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, lighted symbol type and key type, etc., with single button and double Buttons. Generally, it adopts a water-storage structure, which consists of a button cap, a return spring, a static contact, a moving contact and a casing. It is usually made into a composite type, and has a pair of normally closed contacts and normally open contacts, and some products can pass. The series connection of multiple elements increases the number of contact pairs. There is also a self-contained button that automatically holds the closed position when pressed, and can be turned on only after the power is turned off.
When the Metal Switches is not pressed, the movable contact is connected with the upper stationary contact. The pair of contacts is called a normally closed contact. At this point, the movable contact is disconnected from the following static contact. The pair of contacts is called a normally open contact: the button is pressed, the normally closed contact is open, the normally open contact is closed, and the button is released. Restore the original working state under the action of the return spring
