Research Of 3D Ultra HD Business Demonstration System For Terahertz Broadband Communication System

With the rapid development of the Internet of Things,the rapid expansion of the Internet and the rise of emerging businesses such as HD video,virtual reality and augmented reality,the demand for communication network bandwidth in the industry is on the rise.In order to satisfy the demand of the rapidly increasing communication bandwidth,various countries have invested in the research and development of ultra-wideband wireless communication systems in recent years.The industry is in urgent need of a large-capacity service to display the massive data transmission capability of a new generation of broadband wireless communication system in an intuitive and concise manner,and verify the reliability of transmission.This thesis has completed a set of ultra-high definition stereo video demonstration system,including a set of 8 viewpoints free stereo video real-time acquisition device and 58 inch,4K ultra-high definition free stereo video display device with 10 Gigabit Ethernet network card as the input and output interface,PC as a signal processing platform.The thesis designs a special UHD free-space video transport protocol based on user datagram protocol.Multi-core CPU multi-threading parallel processing technology,Multi-level Cache technology,Integrated Memory Control technology and Quick Path Interconnect technology are discussed in detail.The working characteristics of 10 G Ethernet card are deeply researched and the powerful parallel processing capabilities of GPU are uncovered.Combining with hardware features,this paper completed software programming to solve the real-time transmission of ultra-high-definition free-form video based on general-purpose computer platform to bring massive data real-time processing challenges.The actual test results show that the system can achieve real-time acquisition,processing,transmission and composite playback of 4K ultra-high-definition 8-viewpoint autostereoscopic video,which can provide service rates of up to 8Gbps,finely adjust the service rate and intuitively display transmission system error codes and packet loss situation.This system has many superior features including a large amount of data,strong visual impact,high degree of display,and universal interface,and is capable to meet the new generation of broadband wireless communication system demonstration and verification needs.
