Faced with the problem that 4K TVs cannot provide true ultra-high-definition picture quality, the television industry continues to explore. Industry sources pointed out that display technology, content, and bandwidth have always been the key factors that hinder the further development of 4K TV. As early as 2004, Sony introduced the SXRD (Silicon X-tal Reflective Display) silicon crystal reflective display device technology of the digital cinema 4K projector SRX-110/105 to improve the 4K screen display technology. In 2016, China also established the “4K Super Clean Industry Alliance†to integrate various content including video, games, and music to make up for content shortcomings in the development of 4K TV.
After experiencing the constant efforts of all parties, 4K TV has finally caught the moon and finally clears up the layer of “fog and haze†that was enveloped in the early appearances and ushered in a world of its own. According to the data released by the research institutions, 2016 global sales of 4K TV panels were 63.74 million, an increase of 70% year-on-year, and the corresponding market share also increased to 24.7%. Among them, China’s sales of 4K TVs in 2016 also exceeded 25 million units. The staff of the survey agency stated that from the perspective of the current 4K TV’s achievements, by 2020, the sales volume of 4K TVs in China could be estimated to reach 44 million units. It will usher in a new wave of growth in 4K TV sales.
When 4K TV broke the silence of the market, many industries that are closely connected with the development of 4K TVs are also making efforts to help 4K TVs become more popular.
Recently, the person in charge of Guangdong Unicom to launch the 4K Action Plan announced that in order to further promote the application of 4K Internet TV, Guangdong Unicom will establish a 4K industry alliance and fully open "channels, terminals, networks, platforms, users, 4K". Great ability. He Hao, general manager of the company, said that the average downlink speed of the outstanding video network released earlier has reached 44.5Mbps, the average uplink rate has reached 16.8Mbps, and the zero-point rate has exceeded 96%, which will effectively solve the problem of insufficient bandwidth for 4K TVs.
Also making efforts for the 4K TV to become more popular is INsight TV, which has just landed in the United States. According to foreign media reports, in order to further address the shortage of 4K television resources, INsight TV has added 4K channels to provide users with high-quality program content by providing program signals for 4K televisions through TV stations. According to the INsight TV channel, the current 4K channel mainly transmits signals through satellites of SES Europe Satellite Corporation. The program content mainly involves natural and outdoor adventures and other related content.
As a breakthrough product in the TV screen display field, 4K TV has become the darling of the television industry in various countries. In addition to China and the United States and other countries in the 4K field to increase investment, Telefonica, Spain Telecom also said that it will vigorously develop the 4K ultra high-definition television business in Spain, and in 2018 to reach 1 million 4K TV users. Spain also said that on the road to research and development of 4K TVs, they will also focus some of their efforts on developing 4K ultra high definition set-top boxes to better decode 4K TV programs.
With the further development of TV manufacturing technology and the increasing input of various industries in the 4K field, the extent to which 4K television will be developed in the future has also attracted international attention.
On May 23, at the BCE (Big Communication Event) conference held in Texas, USA, on the future development of the communications industry, many experts from the industry conducted in-depth discussions on the obstacles and future conditions faced by 4K TV development. After a deep discussion, experts agreed that in order to fully promote 4K TV, the main problem is to solve the bandwidth, content and set-top boxes.
Although three guests such as Wesley Hicks, Senior Product Manager of EXFO, Monica Revare, Content Partner Director of Layer3 TV, and Neil McRae, Chief Network Architect of BT, did not reach a consensus on how set-top boxes solve set-top boxes, all-fiber-based FTTH The network's 4K service deployment and BT’s launch of the European Football League’s 4K TV channel have given a positive assessment of the positive significance of the 4K TV development process.
Industry sources stated that today's 4K TV market has made great progress. With the support of operators, the bandwidth problem faced by 4K TV has also been effectively solved. The TV station can make up for the lack of content on 4K TV, and the set-top box Problems will also improve with the development of television manufacturing technology. The problems faced by 4K TVs will also be minimized, and 4K will move further towards light.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
Catering to the ever-changing demands of our patrons, we are offering them a comprehensive range of Hot Dip Galvanized Radiator. These are manufactured as per latest market trends so as to ensure their wide applications in industries. Offered products are highly demanded by the clients for their excellent design, longer service life and durability.
Galvanizing is a way of defending a steel surface from corrosion by delivering a surface coat of Zinc. The process is carried out by dipping the radiator in molten zinc bath which is upheld at a temperature of about 450 degrees.
In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association. The use of galvanized steel at temperatures above this will result in peeling of the zinc at the inter metallic layer.Hdg Radiator,Oil-Immersed Hdg Radiator,Hot-Dip Galvanizing Radiator,High-Performance Hot Dip Galvanized Radiator
