On the Performance of Video Quality Assessment Metrics under Different Compression and Packet Loss Scenarios by Miguel O. Martínez-Rach, Pablo Piñol, Otoniel M. López, Manuel Perez Malumbres, José Oliver, Carlos Tavares Calafate

“…When comparing the performance of video coding approaches, evaluating different commercial video encoders, or measuring the perceived video quality in a wireless environment, Rate/distortion analysis is commonly used, where distortion is usually measured in terms of PSNR values. …”

Asynchronous Realization of Algebraic Integer-Based 2D DCT Using Achronix Speedster SPD60 FPGA by Nilanka Rajapaksha, Amila Edirisuriya, Arjuna Madanayake, Renato J. Cintra, Dennis Onen, Ihab Amer, Vassil S. Dimitrov

“…Recently proposed algebraic-integer-(AI-) based discrete cosine transform (DCT) algorithms are analyzed in the presence of quantization, using the High Efficiency Video Coding (HEVC) standard. AI DCT is implemented and tested on asynchronous quasi delay-insensitive logic, using Achronix SPD60 field programmable gate array (FPGA), which leads to lower complexity, higher speed of operation, and insensitivity to process-voltage-temperature variations. …”

VoLTE call setup delay optimization based on signaling message by Bao GUO, Yang ZHANG

“…VoLTE wireless spectrum utilization efficiency is better than that of the traditional CS voice.The introduction of high-definition voice and video codes significantly improves the communication quality.VoLTE call setup duration has been significantly shortened compared to the traditional CS voice.Analyzing the factors in causing call setup delay of VoLTE was focused,and corresponding solutions about the VoLTE call setup delay optimization was put forward based on the signaling message in different stages,including paging,domain selection,resource reservation.…”
