Abstract
With the development of wireless communication technology, video and multimedia have become an integral part of visual communication design. Designers want higher interactivity, diversity, humanization, and plurality of attributes in the process of visual communication. This makes the process of visual communication have high requirements for the quality and real-time data transmission. To address the problem of transmitting HD video in a heterogeneous wireless network with multiple concurrent streams to improve the transmission rate and thus enhance the user experience, with the optimization goal of minimizing the system transmission delay and the delay difference between paths, the video sender and receiver are jointly considered, and the video transmission rate and the cache size at the receiver are adaptively adjusted to improve the user experience, and a cooperative wireless communication video transmission based on the control model for video transmission based on cooperative wireless communication is established, and video streams with self-similarity and long correlation are studied based on Pareto distribution and P / P / l queuing theory, based on which an adaptive streaming decision method for video streams in heterogeneous wireless networks is proposed. Simulation results show that the proposed multistream concurrent adaptive transmission control method for heterogeneous networks is superior in terms of delay and packet loss rate compared with the general load balancing streaming decision method, in terms of transmission efficiency and accuracy.
Highlights
Visual communication design is a planned, effect-oriented design image generation and communication activity that people carry out to achieve certain purposes
Splitting strategy based on cooperative wireless video transmission General load balancing shunting strategy Real-time multi-mode transmission mode Classic video transmission mode queuing theory, and the difference increases with the increase of sending rate. This is because the self-similarity of video streams affects the delay, and more resources need to be allocated to ensure the quality of service, so using the P/P/1 queuing theory, which is more consistent with the self-similarity of video streams, for the streaming decision can provide a better experience to users
This paper improves the expressiveness of visual communication design based on wireless communication video transmission technology
Summary
Visual communication design is a planned, effect-oriented design image generation and communication activity that people carry out to achieve certain purposes (such as information transmission, promotion, expression, and influence). For solving the problem of transmitting HD video in heterogeneous wireless networks with multiple concurrent streams, improve the transmission rate, enhance the user experience, and minimize the system transmission delay and the delay difference between paths; the main contributions are summarized as follows: (1) based on Pareto distribution and P/ P/L queuing theory, video streams with self-similarity and long correlation are studied.
