4K technology began to enter the home of the common people after being promoted for so long.
Nowadays, the new smart TVs all basically support 4K resolution. However, due to the restrictions of policies and other aspects, the television system provides a scarcity of playback resources, so it is necessary to match a strong TV box.
Since the TV is 4K, of course, the TV box as a decoder must also support 4K. The 4K technology has other important parameters in addition to the resolution. Let's take a look at the parameters needed for a good 4K box.
1.H.265 hard solution
H.265 is a new video coding standard that can transmit higher quality network video under limited bandwidth, and only needs the original half bandwidth to play video of the same quality. A good 4K box must support H.265 hard solution, so be sure to pay attention when purchasing.
2.4K 60Hz output
Many boxes now support 4K, but the output 4K resolution specification is only 24 Hz or 30Hz, but according to the BT.2020 standard, the supported frame rate has been raised to 50p, 59.94p, 60p, in order to Catch up with the trend and buy the box to support 4K 60Hz output.
3.HDMI 2.0
At present, most of the boxes in the market still have HDMI 1.4 connections, which can not achieve 4K 60Hz output, and can only support 8-bit color, and can not really display the 10-bit color depth display advantage of 4K video. So now the interface to the box must be HDMI 2.0.
