â– When will foreign 4K STBs be able to watch 4K programs abroad?
It is believed that every TV viewer is eager to see a clearer picture of the TV. In recent years, users have become increasingly demanding on the TV screen, especially in terms of resolution. Today, everyone is familiar with the TV, has been developed from the original 720P HD to 1080P Full HD, to the now popular 4K Ultra HD. So, what is the popularity of 4K TVs around the world?
Last week, another country that announced that it would promote 4K ultra-high-definition set-top boxes was Denmark. In Denmark, cable operator Waoo said that by promoting the triple play policy, it launched a new 4K ultra-high definition smart set-top box. Waoo said that the 4K ultra-high-definition set-top box launched this time cooperates with the well-known Netflix company.

â– Slow development of domestic 4K TV channels
Having said so much, let's look at the development of domestic 4K ultra-high definition television. Before that, some domestic cities opened 4K test channels and conducted pilot programs such as Jiangsu Cable and Dalian Cable. In addition, Gehua Cable in Beijing has also launched a 4K polar column to provide some 4K video-on-demand programming to meet the needs of users watching 4K ultra-high-definition programs. However, overall, 4K TV programs are still very scarce. In the true sense of 4K live TV programs, everyone still feels forever.
â– The author's point of view: how to crack the 4K TV channel dilemma
For now, although the price of 4K TV is slightly higher than that of traditional 1080P, it is not astronomical and many consumers can afford it. Therefore, the price is not a threshold. Another essential terminal, that is, the technology of the 4K ultra-high definition set-top box is not complicated. By adding the H.265 decoding function, you can smoothly play 4K ultra-high-definition television program signals. The problem that needs to be solved now is the source problem.
Cable TV operators and TV stations did not have enough 4K ultra-high-definition programming resources and did not consider using 4K ultra-high-definition cameras for shooting during the production. Even when some TV dramas and movies were filmed, they were shot with 4K ultra-high-definition cameras. In post-production, considering the production cost and other reasons, they still provided only 1080P full HD resolution television signals. The cost of 4K ultra high-definition television programs in shooting and post-production has increased, and it has to be considered by television producers. However, as a public welfare undertaking, radio and television, the national prefix TV station should still play a leading role in upgrading the existing high-definition channels, using 4K ultra high-definition resolution shooting, production and broadcast. In addition, SARFT and other relevant departments should also formulate 4K ultra-high definition television program transmission specifications for the cable industry and promote the development of 4K ultra-high definition television.
