In contrast to traditional signals, the data flow rate of ultra HD 4K / 8K signals has grown sharply: 4K content pixel size is at least four times more than 1080p, and 8K is more than 16 times more than 1080p. At present, video transmission and switching equipment is mainly popular with 1080P standards, most of the transfer protocols and coding techniques are prepared for 1080p signals. Even if H.265 encoding, and even more advanced encoding compression technology, the transmission and switching system is still amazing in the ultra HD era.
At the same time, ultra HD is not only an increase in pixels. In many fields, it is a change in the quality of the fundamental quality. The national super high-definition standard includes "high dynamic range (HDR), wide color gamut, three-dimensional sound, high frame rate, high-color deep" - every new quality of quality here means adding more Many "information quantity", more demand, larger transport bandwidth and switching system backplane bandwidth.
That is, 1080p transmission and switching may only need 4Mbps; 4K system requires 40 Mbps; more advanced 8K systems require 150 Mbps - this is a quantitative jump. It is also a large "bandwidth demand" that is unprecedented in video communications.
From the history of transmission and signal processing industries, each "video clarity" will be a huge "technological innovation" revolution. This is true for the Summit to HD era, and the HD to the full HD era is also true. The difference between the information of the full HD and 4K is almost equivalent to the gap between the standards to the full HD: Don't say the country clearly propose "4K first, take care of 8K" goals. If the transmission and handover demand in accordance with the implementation of 8K, this signal transmission and processing industry will be "unprecedented" huge leap, which means huge innovation opportunities.
More importantly, the application of super high-definition era video will also be more diverse. For example, remote surgery in the medical field, the vehicle network of smart driving, etc. - the requirements of these applications on "real-time performance", the previous video industry has never appeared. To ensure that transmission and switching real-time, more bandwidth redundancy, higher processing and computational speed, to greatly eliminate the "congestion" in the signal processing.
It can be said that in the face of the rise of ultra HD, the technical standards in the signal processing industry is "quantity and quality" double high standards. Implementation of bandwidth growth, perhaps "stack" lazy ways; real-time quality requirements must be a huge challenge than spelling hard work - this for signal transmission and processing industries will be a huge challenge.
Multi-application scenario under concept, large market for signal transmission and processing
The development of the ultra HD video industry is not only the "improvement and efficiency" of the application department, but also a huge expansion opportunity for video applications and categories. Experts believe that with video capture, transmission, especially intelligent technology, the diversification of industry application models, expansion of application categories is a huge opportunity.
The National Super HD Video Action Plan pointed out that in six fields such as radio and television, entertainment, safety supervision, medical, transportation and industries, and the ultra HD video has huge application needs. In the fields such as entertainment, it can still be subdivided in many different application types, such as "Super HD Education Plate, Projector, Conference Plate, Interactive Intelligent Terminal and other teaching products, driving ultra HD video technology in the Digital Museum, Application of the real defense, art appreciation and so on. "
Based on the diversification of application scenarios, ultra HD participation subjects, demand equipment is also diversified. It can be said that the development of the ultra HD industry has promoted the "signal transmission and processing" technology and equipment "performance improvement", which also provides a rare opportunity for "application" expansion - Ultra HD application ranges, It means that there is how much the market increments of the signal processing industry.
In summary, the launch of the ultra HD Industry Action Plan is a huge opportunity for signal transmission and processing industries. Representatives are represented by high bandwidth, real-time, and wide application scenarios, and make full use of many new technologies, the new theory's industrial application innovation drama has kicked off. The signal processing industry will also enter another gold period.
