Maybe you have already purchased a 4K TV, but still can only use it to watch SDTV, HD online video, which is obviously an incomplete experience. In fact, Ultra HD Blu-ray 4K Blu-ray discs will still be available for some time, will become the main 4K film source, and the other form is streaming media.
At present, some foreign streaming media such as Netflix and Amazon have launched 4K streaming media channels, and domestic companies such as LeTV and Huadian have provided a small amount of 4K sources, but it is certain that with the increase in broadband speed, bandwidth, and 4K With the increasing popularity of television, 4K streaming media resources are inevitable. However, not all 4K TVs or players can support 4K streaming media. Here's a look at the standard differences.
HEVC encoding and HDCP 2.2 specification
The first thing we need to understand is that 4K streaming media uses a new HEVC encoding (H.265), so the playback device (TV box, media player, or smart TV) needs to support the encoding rules. In other words, some older devices are not able to support this code through software upgrade due to hardware design. At present, only a few devices such as the Sony FMP-X10 media player clearly support HEVC encoding, so most existing TV boxes cannot really support 4K streaming video.
The second is the HDCP 2.2 specification, which is a hardware-based copy protection mechanism that typically requires hardware, interfaces, and software to support this feature. In other words, some of the 4K streaming media content in the future will force devices that support the HDCP 2.2 specification to play.
Therefore, if you want to purchase a 4K streaming media player or an expandable 4K smart TV, be sure to understand whether they support HEVC encoding and HDCP 2.2 specifications in order to better experience the ultra-high-definition streaming media content in the future.
