If you want to watch 4K TV programs broadcast live on TV, in addition to having a UHD-quality TV, the 4K TV set-top box is also a must. Only in this way can you watch normally, because many online 4K live programs are often The 4K resolution is not reached on the picture quality, so the best receiving device is to watch the 4K program through the cable TV network. Recently, ABIResearch, a well-known market research institution in the United States, released a set of forecast data. The data shows that within the global scope, as of 2020, the number of 4K TV set-top boxes will reach 48 million.
However, at this stage, many countries are only piloting or officially broadcasting 4K television signals. Only a small number of users have enjoyed the shocking effect of 4K television. According to statistics, the number of 4K TV set-top boxes in use worldwide was only about 60,000 units in 2014. However, as more TV stations try to broadcast 4K TV signals, the demand for 4K set-top boxes will increase exponentially.
In addition, the use of HEVC, that is, the set-top box supporting H.265 encoding is becoming more of a focus of attention, including a number of companies including NTT’s TV operators and British Sky Broadcasting Corporation, all of which have a 4K set-top box. Larger use requirements. Interestingly, at present, many products have adopted the 725X series SOC decoder chip developed by Broadcom, Broadcom, I guess the reason should be better support for the current HEVC encoding. However, the problem at this stage is that compared to ordinary 1080P Full HD set-top boxes, the manufacturing cost of 4K TV set-top boxes is relatively high. How to reduce production costs is also a problem that needs to be faced.
