“…The fast-changing communication technologies, such as the deployment of 5G and the development of 6G, greatly promote network bandwidth and data delivery quality for the mobile Internet, which effectively supports online services with high requirements of bandwidth and delivery performance (e.g., video-on-demand and video living) [1][2][3][4]. The video services rely on rich viewing content to attract a large number of users, which generates huge traffic demand and consumes a mass of network bandwidth [5][6][7][8]. Currently, there is a deep integration between video services and social networks.…”

Social networks open up a new channel of video sharing and promote the scale and efficiency of video diffusion. Adjustable and scalable video diffusion is significant for the quality and performance of the service of video systems. In this paper, we propose a novel epidemic-based video diffusion strategy using awareness of sociality and mobility in wireless networks (EVDSM). EVDSM constructs a video diffusion model with the consideration of interest preference, social influence, and user mobility according to the roles and the propagation process of the Epidemic model. EVDSM designs an estimation method of interest preference according to content similarity and preference discrimination between videos; EVDSM designs an estimation method of user roles by investigation of interest preference and social influence to identify the video sharing behaviors of users and define the roles of users; EVDSM designs an estimation method of user mobility in terms of data transmission time and path structure stability. EVDSM proposes a control strategy of video diffusion, which formulates priority-based pairing between infectors and candidate infectors to achieve joint optimization of pairing success rate and delivery performance. The simulation results show how EVDSM achieves much better performance results in comparison with other state-of-the-art solutions.

“…In [11], in order to make full use of the common scene frame, besides the I frame, the P frame can also refer to library frames for inter-prediction. Focusing on obtaining the optimal long-term reference frame, Jubran et al [12] use the structural similarity of pictures to select the sequence-level long-term reference and obtain significant rate gains. Furthermore, Paul et al [13] proposed to determine the I frame based on the number of objects in the stable scene and adjust the length of GOP to extend the interval of inter-frame reference.…”

A video coding framework for the apron surveillance scene has been proposed in this paper, which aims to improve coding efficiency by eliminating long-term redundancy at the object level. To achieve this goal, this study first develops an existing block-based hybrid video coding framework by exploiting the video redundancy on the object level to perform video coding. Second, an object-library mechanism is designed to collect the representative object images as coding references on larger temporal and spatial scales. Finally, a virtual reference frame, which blends background and foreground references from the object library, is adaptively composited according to the video content to improve the interprediction performance. Preliminary experimental results demonstrate that the proposed method achieves a high BD rate reduction of up to 23.97% in apron surveillance video sequences, compared to the standard high efficiency video coding (HEVC).
