I. Product Overview and Appearance As a well-known SOC solution provider in China, Rockchip Microelectronics has launched a high-profile launch of the RK3288 platform last year. Although due to various reasons, this processor is not widely used in the tablet market, but its high specification performance is still left a deep impression, and appeared in Google's new generation of Chromebook notebook above. In the field of set-top boxes, Kepler has a deep background, this time it also used it to create a TV box product. Rockchip RK3288 excellent decoding performance and graphics configuration, are very suitable for audio and video entertainment and the main function of the box products.
Even more eye-catching is that this product uses an amazing 4GB of memory. To know that the current use of RAM for box products still stays at the level of 1GB, 2GB can be considered a higher configuration, and Kaibor F6 uses 4GB of memory in one fell swoop. For Android STBs, which require long-running devices, the large memory provides a more stable and smooth experience. The disk space for storing multimedia files also reaches 16GB, and the memory configuration of the machine can be said to be the leader in the box product. Therefore, the author also expects more from its actual performance. Interested friends may wish to learn together.
Kaibul F6 still adopts a unified packaging design. The accessories are similar to those of the previous products, including HDMI output cables, power adapters, and remote controllers that support learning functions.
Although the hardware configuration has made a big leap, the appearance of this product is still relatively low-key, and it is similar to many previous Kaibor products. The all-metal black matte shell looks more honest.
Front side design is simple, circular infrared receiver window, next to the boot status indicator
The serial number on the left side of the fuselage matches the package
F6's storage expansion interface is very rich, including a TF card slot and three USB2.0 standard interfaces to facilitate the external U disk and mobile hard disk and other devices, which can ensure fast data reading speed. Second, the interface and body details
The other interfaces are centered on the back, and since the USB is on the side, the rear interface does not look so crowded. The corresponding interface in the figure is the wired network port, optical audio output, reset hole, composite audio output, HDMI output, and DC power supply hole. It also reminds that HDMI does not support hot swapping to avoid damage to the device.
Two antennas that support large rotation ensure excellent wireless signals. In actual use, a sufficient network strength can be ensured in the case of six or seven meters across the router and through the wall.
The back of the design, it is strange that there is no design ventilation window
The four corners are fixed by screws, and the side pad is to prevent the body from falling off.
Tear off unprotected labels, nothing will not disassemble
Product nameplate III. Interface design and fluency
Kaibol F6 does not have a power button. After connecting the power supply and video output cable, it will automatically start up. After waiting for tens of seconds, we can enter the familiar KUI interface. This system has been introduced many times in the past, it can be said that it is a relatively complete and mature box UI interface. Its control response is very smooth, reflecting the advantages of high-configuration hardware.
Among the front-end KBoard set-top boxes, some use Alibaba Cloud OS, which has a rich application suite built-in. And this new product does not carry Aliyun OS, its pre-installed program is very streamlined. The online video client that needs to be used must be downloaded on its own, and the software market recommended by the system can be installed before this.
This machine is equipped with 4GB of memory, a key can be cleared after more than 3GB of space, and because of such ample memory, usually do not need to clear the memory, can guarantee its long-term fluency and stability, which is also a large memory The advantage lies.
There are few pre-installed applications, perhaps related to the delivery of prototypes. At present, F6 is not listed. The final production version may provide more software. If you have to install it manually, you still have trouble.
WiFi Display is a function for displaying in the same screen as a mobile phone
The XBMC media center software that comes with it will automatically pop up during the loading process. It should be a small bug of the tester.
After installing the sofa butler, you can download as many software as you like for your box.
CIBN Internet TV is also the post-installer, through which you can order all kinds of popular video content, smooth control, intuitive interface. In addition, users can install a lot of online video aggregation software according to personal preferences.
Or take CIBN's video on demand function as an example. Due to the strong hardware processing performance of this machine, the network performance is also very good, and the delay in the response of dragging during playback is very small. In terms of picture quality, it is greatly influenced by the software used. For the sake of clarity, clarity in ultra-clear mode is still relatively good.
Play in super clear mode
The live TV feature can also be implemented by installing software. I installed the HDP Live Streaming client.
It provides a large number of high-definition stations, the screen as much as the effect of the wide-area roof box, and more worthy of recognition is that the exchange delay is very short, basic and wide motor top box is almost the same. Of course, this is related to the specific network environment. The author uses 40Mbps broadband. Now, with the increase in broadband speed and fees, the overall effect of watching online TV broadcasts is also improving. Fifth, the local decoding effect test
The own resource manager interface is more beautiful
Rockchip's micro-project has previously been the highest support 1080P specifications, RK3288 is its first program to fully support 4K and H.265 encoding, and the box product is very much in line with the high requirements of video decoding. More than ten segments of 4K video clips have been tested continuously. The code stream can range from a few Mbps to hundreds of Mbps.
Watching 4K video on a 4K screen is definitely a pleasure
H.265 coded test piece can also play smoothly
Rich options, set up is also very simple Six, other applications and hardware analysis
The built-in browser can be used to browse web pages. There is no problem with the speed performance. It is not easy to operate. Fortunately, the open remote control supports mouse mode. After switching, you can perform various pointing operations.
Support online upgrade
Kaibol F6's settings interface is still a native Android setting option, not modified to a more suitable interface for remote control operation, but you can see its video output can support 2160P, or more rare. At present, the most popular box solutions, including Quan Zhi and Actions, all support only 1080P output.
There are also some details for screen display
Rockchip RK3288 uses a high-performance Cortex A17 architecture, four-core design, 28nm process, the maximum frequency up to 1.8GHz, the display chip used is the ARM high-caliber Mali-T760 series, excellent graphics performance. And its memory capacity is as high as 4GB, unprecedented enough. It should be noted that, from the software monitoring point of view, the actual output of this level is the 1080P effect of amplification to 2160P, slightly higher than the actual output specifications of the previous 720P, such as Quan Zhi, Actions, etc., but still does not reach the 4K point-to-point output, not Not to say it is also a pity. Fortunately, the current 4K TV penetration rate is not so high, 1080P specification TV is more common, direct selection of 1080P output mode will be able to achieve a clear point-to-point effect.
Up to 36,000 points of test results are more than twice as many as the H8 eight-core solution, reflecting the advantages of the high-performance A17 architecture. Kaibor F6 trial summary: Kaiboer F6 smooth performance of the whole machine performance is satisfactory, RK3288 high-performance CPU with 4GB large memory provides an excellent hardware platform, it is regrettable that its own pre-installed applications and functions done relatively simple, if Alibaba Cloud OS can be added just like the previous ones, and the usability will be significantly improved. However, the system tends to be purely purified. For some users who like DIY software, it is good news to reserve more storage space to install their favorite software.
The RK3288 bandwidth is used as 4K, and the memory bandwidth is insufficient.
In addition, eMMC estimated that the version is also very low, with a Shenzhen company's products, slow, so the test prototype did not install any software, so Kaibule F6 did not design the power button, after connecting the power and video output lines will automatically start, wait After tens of seconds, we can enter the KUI interface that we are familiar with. Now we don't need to open a computer for a long time, which seriously affects the user experience.
In addition, the memory has long been general, 999 minus 100 high prices. RK3288 a flat screen with a price geometry?
2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
Even more eye-catching is that this product uses an amazing 4GB of memory.

Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.
Advantages
1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
