4K is already a standard when many friends buy TV. This year, the company added HDR as a new technical standard on the basis of 4K, making the 4K picture more splendid and more beautiful. However, although 4K TVs are basically equipped with smart systems that can download and install streaming media applications, some vendors also provide 4K online video, but network bandwidth is always a problem.
Recently, US cable and network operator Comcast introduced new network traffic policies in some markets, allowing users to consume up to 1TB of traffic before recharging. So, does this mean that 4K HDR content will become a big traffic, and at the same time, what bandwidth does 4K HDR content require to play smoothly?
HDR TV and content popularity rapidly
First of all, what is certain is that 4K HDR TV will become the new darling of the market. After all, the "Ultra-HD resolution" alone is not enough to attract users, but better picture quality is obviously possible. This year, most TV manufacturers are focusing on 4K HDR TVs. Some of the low-cost 50-inch models only need about 850 US dollars (about 5,530 yuan). It is believed that after one year, HDR will become a standard feature for high-end, mid-range 4K TVs.
On the content side, temporary overseas suppliers such as Netflix, YouTube, Amazon, etc. have launched quite a lot of 4K and HDR streaming media content. It is expected that Time Warner, DirecTV, Verizon, etc. will also actively follow up, and other countries and market streaming media manufacturers You will also see this trend and actively promote it. For some picture quality users, subscription fees and on-demand fees are obviously not a problem. In fact, for Netflix, for example, the price of 4K HDR content is only $2 more per month than the base monthly fee.
Bandwidth and data traffic will be the key
To be sure, broadband bandwidth and traffic will be the threshold for 4K HDR streaming video. Netflix recommends that users need at least 25 Mbps per second, and according to third-party estimates, playing a 4K HDR video requires about 675 GB of average traffic.
According to this rate and traffic loss, the bandwidth of some packet flows is obviously unacceptable to users, and bandwidth speed is obviously a hard threshold. If the broadband operator in the user's area is unable to provide real high-speed broadband and affordable packages, then 4K HDR TV will obviously become a temporary device again, and it will not be able to play a real role.
