Analysis And Synthesis Of High Definition Video Streaming For Wireless Communication

Abstract

In present scenario High Definition (HD) streaming has a major role in the field of newlinedigital wireless communication system. 4G and the upcoming 5G is the major technological newlinesupport along with Wi-Fi, Wi-Max and LTE. The occurrence of error is one of the major newlineproblems in wireless communication which will not only reduces the effectiveness and security newlineof the system but also affects the degradation of the information at the receiver end. Today the newlinemajor areas of applications like gaming, messaging, internet, and multimedia applications newlineexpressing the need of high speed, huge data transmission, high resolution and good quality of newlineservice. Thus High Definition came into existence as a successor to Standard Definition to meet newlinethese requirements. newlineIn HD video streaming packet losses and transmission errors are the major challenges newlinealong with noise and flickering effect. The total spectrum of the work will be concentrating on newlinerectification of these problems faced by HD especially in video streaming. In the proposed work newlinedigital modulation scheme, storage analysis and series of novel error correction techniques are newlineconsidered for the analysis of the above said problems. The experimentation will be done and newlineanalyzed for various standard high definitions streaming format. The best method has been newlinesynthesized using Verilog Cadence tool. The whole simulation has been carried out using newlinematlab. The areas of application include satellite communication, broadcasting, data storage, newlinemobile communication, multimedia applications, internet etc. newlineHybrid Quadrature Phase Shift Keying (HQPSK) is a digital modulation and newlinedemodulation technique is devised in order to improve the bandwidth efficiency and reduce the newlinesymbol error rate. This method is compared with Quadrature Phase Shift Keying (QPSK) and 16 newlineQuadrature Amplitude Modulation (QAM) schemes. The simulation results show better newlineimprovement in the proposed work. Because of orthogonally this method is well suitable for newlineOrthogonal Frequency Division Multiple Accesses (OFDMA) platform also. newlineFor the purpose of storage analysis a synchronous counter is designed. It not only helps newlinein huge data storage but also maintains data security and error free information. Approximately newlineit can able to hold the information of 4GB in 32 bit synchronous counter. The data may be in the newlineform of information image or video can be recovered at the receiver. For transmission of the newlinedata can be processed by the application of clock pulse. newlineIn the error correction methods, Reed Solomon (RS) encoder is designed to correct the newlineerror up to four bytes. If the number of errors is more than four bytes in an input video frame newlinex newlinethen the proposed methods getting into action. The proposed methods are eight cell method, newlinediagonal method, Z-method, plus method, and hybrid method shows high gain priority compare newlineto other methods. newlineIn order avoid packet loss during transmission and retransmission LSB method of error newlinecorrection is used. In this proposed method the MSB information is pushed to previous LSB newlinebits. The four methods are considered throughout the spectrum of this work to analyze the newlineperformance matrices and optimize to reach the major challenges. newline
