Summary: This paper studies a collaborative caching-transmission method in cache-enabled terahertz (THz) heterogeneous networks to mitigate the impact of the dramatic growth of wireless video traffic. A novel scalable video coding (SVC)-based two-tier cooperative caching strategy and a hierarchical hybrid transmission scheme are proposed. Simulation results demonstrate that the proposed method can achieve quasi-optimal performance.

Summary: Freshness and quality are important metrics in real-time video applications, but often conflict with each other. This article focuses on studying the tradeoff between freshness and quality using scalable video coding and adaptive random network coding. By maximizing defined utilities, an excellent tradeoff between freshness and quality can be obtained, effectively solved by heuristic and deep Q network algorithms.

Summary: This article addresses the provisioning of multiple statistical Quality of Service (QoS) for real-time scalable video streaming over wireless fading channels. It presents a traffic rate adaptation (TRA) strategy that delivers encoding layers selectively based on dynamic channel conditions, minimizing video quality variation while maintaining satisfactory average video quality. The QoS-guaranteed TRA policy optimization is formulated using Markov decision processes, and a vector-composed policy gradient algorithm is developed for online mean-variance optimization. Simulation results demonstrate the effectiveness of the presented strategy.

Summary: This paper proposes a content adaptive downsampling scheme based on video content characteristics to improve video coding efficiency at a low bitrate. The scheme extracts content-aware spatial-temporal features and uses Support Vector Machine (SVM) to predict the optimal coding configuration for the video. Experimental results demonstrate considerable bitrate savings with low computational complexity for video sequences at different resolutions.
