[Parameter configuration]

RK3328 processor uses 64-bit A53 architecture quad-core processor, clocked at 1.5GHz, GPU uses Mali-450MP2, supports Android 8.1 and Linux OS system, can support 4K60 frame video decoding, the latest 4K ultra HD (UHD Premium) ), HDR10/HLG and other international standards.

Support USB3.0 and Gigabit Ethernet data transmission.

[System UI and Features]

The tv box boot speed is very fast, from the start to the main page UI display, the whole process is about 30 seconds. Compared with other android tv boxes, RK3328 tv box has a good boot speed.

The front page system UI adopts an interface design similar to the win10 system style, and the option menu is directly presented in front of the user in the form of a poster, and the display content is richer and more intuitive.

The system has built-in movies and TV dramas such as YouTube, Netflix, TED, etc., which brings together the latest and most popular movies and TV dramas in the world. Users with accounts can log in and watch them.

The application bar is set at the bottom of the homepage. Users can customize the order before and after, and bid farewell to the traditional tv box classification, saving a lot of operation steps.

[Quality test]

The smart android tv box with RK3328 chip supports the latest international standards such as 4K Ultra HD (HDD Premium) and HDR10/HLG. which is:

1, 4K should be 3840×2160 or 4096×2160 in the image quality output, and the frame rate per second is at least 60 frames.

2, with HDR high dynamic lighting rendering technology, HDR technology can effectively improve the image quality contrast, adjust the color gamut and lighting, so that the details of the bright and dark areas can be better displayed.

3, H.265 hard decoding, the current 4K film is basically using H.265 encoding technology, so to output these film sources, you must have H.265 hard decoding capabilities.

4, to achieve 10bit color depth, true 4K color depth from 8bit to 10bit, compared to the previous 8bit, in the color gamut and color quality fineness has nearly doubled (gamut coverage reached 78.5%), There will be no 8-bit color shading or uneven color patches.

Here are some of the standards, to actually test the image quality of the smart android tv box!

By playing the 4K resolution test chart, we can see that the font size and font color can reach the 4K resolution standard. The color blocks in the test chart can also be clearly distinguished. Even the dense color block structure at the bottom can be correct. Showing the details, it did achieve 4K resolution.

With the RK3328 smart android tv box, the picture quality is even better than the traditional tv box. By playing high-rate movies, even in complex environments, the RK3328 tv box can clearly show the details of the house, even in the distance.

RK HDR to SDR conversion technology, so that ordinary TV also has an enhanced picture quality experience.

The blessing of HDR high dynamic lighting rendering technology makes the image quality of the RK3328 tv box even better. Below we compare several sets of HDR and non-HDR.

By playing HDR video test, the overall brightness of the screen in HDR mode is higher, the color is more vivid, and the picture performance is more user-friendly.

Especially in the dark or even dark environment, the HDR high dynamic range performs better. Just like in the picture, the background of the characters is pure black, and at the same time, the overall color contrast of the picture is increased, and the detail performance of the bright and dark places is greatly improved, and the picture is brighter than the HDR-free technology.

[Data Transmission Test]

The RK3328 tv box not only supports Gigabit network transmission, but also has a USB3.0 data interface. We will test them separately below.

1, network speed test

We passed the test results of RK3328 tv box wired network and 2.4G/5Gwifi: cable 11.8MB/s, 5Gwifi10.0MB/s, 2.4Gwifi3.869MB/s. (In order to get more objective data, the tests were averaged multiple times)

Compared with other smart android tv boxes, RK3328 network transmission speed is ideal, in which the wired network transmission speed ranks among the best in seven tv boxes, and the network speed in the 5Gwifi band is also in the forefront.

2, USB3.0 transmission speed test

The RK3328tv box is equipped with a USB 3.0 interface for faster data transfer. How much faster is USB3.0 than USB 2.0? Let's test it out.

We test the data transfer speed by writing and reading a certain amount of data to the USB3.0 interface. Each read and write is performed 3 times and averaged. Finally, 16MB, 8MB, 4MB, 2MB, and 1MB were selected for data recording. We use 16MB as the reference standard, the average write speed is 95.39MB/s, and the average read speed is 97.67MB/s.

In the USB2.0 interface data speed test, we can see that the average write speed of 16MB is 34.64MB/s, and the average read speed is 33.07MB/s.

The curve comparison diagram of the two intuitively reflects that USB3.0 is three times faster than USB2.0, and the data transfer speed is faster than USB2.0.

In order to let everyone more intuitively feel the data transmission speed gap between the two, we selected a 1.1G test film, copied to the RK3328 smart android tv box and the traditional tv box, comparing the time spent. It can be seen that the RK3328 smart android tv box completes the entire movie copy in only 59 seconds, while the traditional tv box takes 2 minutes and 32 seconds.

[Video decoding test]

As a smart android tv box, the local chip source decoding capability has always been the focus of the majority of enthusiasts. Below we will test the RK3328 tv box in different formats, different bit rates and 4K, HDR source decoding capabilities.

According to the results of the Antu rabbit video test, 27 supported formats, only 3 incomplete support, avc, mpeg-4, and vp8, respectively, and the three video encoding formats are stuck.

We tested through different video encoding formats, and 14 test videos were able to play smoothly. There were no jams, dropped frames, or unclear video during playback. In addition to mp4, avi, mkv and other common video encoding formats, evo, flv, tp, m2ts and other formats can support decoding and playback.

The video bit rate is directly proportional to the video quality. For the video bit rate, it can be understood as the sampling rate. The larger the sampling rate per unit time, the higher the precision, and the closer the processed file is to the original file, the higher the bit rate of the video, the clearer the picture. According to the test, the RK3328 tv box can smoothly play test videos of different bit rates.

The code rate is up to 125Mbps test film, RK3328 tv box can also support smooth playback, (many traditional tv box, smart TV broadcast 125) from above the city, the details of the city building, the chimney of the roof, the vehicles passing by the street and the prospect The details of the buildings in the building can be clearly displayed.

In the 4K and H.265 video tests, the RK3328 supports smooth playback of all test videos. The latest HEVC video compression technology video also supports decoding and playback. In addition, videos with higher 10-bit color depth have better performance on the actual playback experience. Careful, the color gradation is more delicate.

It is worth mentioning that the RK3328 tv box not only supports the playback of 3D movies, but also supports left and right 3D to 2D, up and down 3D to 2D and other functions. In addition, like the selection of audio tracks, external subtitles, and adjustment of subtitle size, the RK3328 tv box can support.

Written at the end:

As a high-end processor chip, RK3328 has excellent hardware performance (supporting Gigabit network and USB3.0), as well as 4K, HDR and other video decoding capabilities (fast running speed, clear and smooth playback quality, The playback function is comprehensive), which left a deep impression on us.

The RK3328 processor perfectly satisfies the daily use of the mid-to-high-end smart android tv box, and interested users can pay attention to it.
