What to buy set-top boxes for 4k TV

With the popularity of 4K TVs, 4K Internet TV set-top boxes are also beginning to beconcerned about, people want to buy a "time never fall" - TV box can use later, 4K TV set-top boxes and the general set-top boxes difference there? What to buy a TV set-top boxes 4k 4kTV set-top boxes with what is better?

What 4k TV set-top box? The saying goes, a good horse with a good saddle, 4K by 4K TVset-top box is the best thing, of course, first of all ask you to understand what is 4K networkset-top box? 4K TV set-top boxes and general difference there?

4K network configuration set-top box

4K network set-top box industry, said the "super-clean monster", we can see that he'sconfiguration must be high. Because ROM is cured, but also by TF card expansion, will not be discussed here Kudat ROM size of the problem, we only focus on CPU, ROM memory.

1, CPU program
Kudat Recall that the current A20 / 31 program full-Chi's support 4K decoding. Said it should be prepared A20S / 31S, full-Chi A20 is a low-end dual-core CPU program, which uses V7architecture clocked at 1.0G Hz, 45NM process, in order to gain more market, upgrade to full-Chi A20 A20S support the latest 4K decoding, full-Chi A31S also upgrade from full-Chi A31, the quad-core V7 architecture, features still support 4K decoding. 2015.1.27 Update crystal morning AML S802 / 805/812 program, Rockchip RK3288, Hass 3798 and other programsalso support 4K HD decoding.

2, the memory size
4K network set-top boxes in addition to the CPU requirements of the program, there are certain memory limit, set-top boxes using ARM processors are intelligent systems, due to theandroid system on hardware boxes have certain requirements, so we can understand the general single-core CPU box is android4.0 system, or we can say that as long as the box 4.0systems are outdated garbage box, their memory is generally 256M, this box to run the gamevery card let alone a 4K HD.

With the escalating android system, as long as the current dual-core boxes are generallyandroid4.2 system, observe Taobao box prices, we can find some tricky. 199 dual-core set-top box is generally 512M memory, due to the ability android4.2 system memory for just about400M, 512M so the $ 199 box of available memory pitiful. Generally watching TV, video-on-demand is not a problem, but playing games, watching high-definition HD movies might a bit difficult.

1. CPU program

4K biggest highlight is the network set-top boxes to support 4K HD, other features commonSTB are also available. But at the moment only a handful of programs that can decode 4Ksources, so the set-top box supports 4K program is relatively small, only full-Chi's dual-core,quad-core program support.
2, the memory size

The above mentioned network set-top box configuration, network set-top box also mentioned4K memory size, in general, than the average set-top box to set-top boxes 4K memoryrequirements are relatively high, so the minimum set-top boxes 4K memory is 512M, 1G ingeneral.

Our high resolution 4K TV, reaching four times the 1080P HD, so the effect if an ordinarymovie, ordinary television set-top boxes in the 4K display may not be good. If it touches a livedoes not matter, if it is on-demand HD movies, the general set-top box may be a bit not to force. Local HD player, set-top box is more common not to force. For example, to decode 4K, HD Blu-ray, ISO image file, etc., can not meet the general set-top boxes. So then again, a good horse with a good saddle. 4K TV set-top boxes to use 4K.
