Two days ago, Station B officially announced its support for 8K video! The key is that the video members of station B are only more than 100 yuan a year after the discount, so we can enjoy 4K and 8K Dolby Atmos? Probably not, the bottleneck here, most likely is your home router. The old router is determined to be obsolete first
The router with the largest shipment in China is TP-Link. The inventory share in the market is very high, but many of them are actually 802.11abg products. These ancient products are still using the ancient protocols of 802.11 a/b/g, if your router at home is still like this, then quickly replace it, there is no need to keep it.
8K, the old router says goodbye
But the B station 8K video is not good, the recommended code stream reached 60MB, the peak is 180MB, this bandwidth these ancient products can not carry.
4K look at the stream router looks at MIMO
The same 4K video can actually be very different. We take the movie as an example, the domestic Web-DLP, that is, the website online to watch the movie, although known as 4K resolution, but the code stream is generally relatively low, only a few G, this although the device requirements are not high, but the picture quality is also not high. The representative of high picture quality is the recently released Lord of the Rings 4K, a single movie 180G, this capacity 802.11n transmission is no play.
A movie with the capacity of 3 BD disks can be loaded, just ask you are afraid or not?
So wifi 5, or 802.11AC, does it work? This bandwidth line. But can not ensure that it does not look stuck, because this also involves the problem of decoding, 4K high code stream and 8K inherent high code stream on the decoding requirements are very high, sometimes the caton from the decoding ability is insufficient, rather than the transmission speed is not enough, here is recommended is to get a strong ability of the box to play, the TV as a pure display output, unless your TV is very expensive, with a very high processor configuration. And routers, boxes, tv sets are best in a room, 5GHz this channel signal through the wall is very poor, to ensure that as far as possible direct connection.
WiFi6 and 6E
Wifi6 is the standard in 2018, a new round of bandwidth acceleration, its improvement is actually a bit too much for home use, there is no demand for so many devices at home, even if the light bulbs and sockets are networked. Now the situation is that the cheap WiFi6 router scheme is general, and the good generally needs one or two thousand, depending on the personal budget acceptance ability.
Wifi6 is of course better, but supporting good routers is generally more than a thousand yuan
The people's hearts are not enough to swallow the elephant, and now the WiFi Alliance has come out with an expanded version called WiFi6E. The difference is that 6E uses one more frequency band, that is, 6GHz. But there's a problem with that because spectrum resources are limited, not every country has approved 6GHz for use in Wifi, so 6E can be ignored.
Box support for wireless signals and decoding support are more important
I believe that after the B station, there will be more video websites to support 8K, and we will also usher in a new round of equipment upgrades, from the core TV set to the router to the TV box, to achieve a comprehensive upgrade to achieve higher picture quality. But if it is not the obsession with the 8K mania and the 4K high code stream, it is actually a big project and a low cost.
The future belongs to 8K, but now the touch future cost is a bit high, and the content is too little, the gimmick is greater than practical, 4K is more practical, more appropriate choice, mainstream Blu-ray movies, web dramas, games are also this resolution, at this stage of the high-quality 4K HDR + Dolby Atmos system to do a good job, is the best video experience at the moment.
