4K TV has long popularized the 4K Ultra HD test channel has just arrived
Although 4K TV has become widely popular in just a few short years, the availability of 4K content remains limited. To promote the application and industrial development of 4K ultra-high-definition television, the State Administration of Radio, Film and Television has designated Guangdong as a pilot province for 4K UHDTV. Additionally, Guangdong Radio and Television has been supported to adjust its existing 4K broadcast system to meet the latest standards.
Watching 4K ultra-high-definition TV is not as simple as it sounds. In addition to having a 4K-compatible TV and set-top box, the signal source, transmission network bandwidth, and other infrastructure must also meet the requirements for 4K transmission. For example, a single 4K TV channel can require nearly 50M of bandwidth. This means that both broadcasters and consumers need to invest in better infrastructure before 4K becomes truly accessible.
Currently, 4K Ultra HD channels are still in trial stages, and it will likely take some time before they are widely promoted and adopted. Before 4K programming becomes mainstream, we might even be looking at 8K TVs as the next big step in display technology.
