Max-sum and max-min fair PSNR for video transmission

Abstract

In communication system, allocating resources is one of the important issues because resources are limited. Most of researches and algorithms on communications take Max-sum or Max-min as their objective. In this paper, we analyze the Max-sum and Max-min fair objectives for video transmission. Peak Signal-to-Noise Ratio(PSNR) is used for measuring video quality. First, we analyze for the single link case for both Max-sum and Max-min fair PSNR. With that result, we extent to the multiple link case analysis and suggest algorithm for Max-sum and Max-min fair PSNR. Finally, we compare Max-sum PSNR and Max-min fair PSNR with several factors affecting to results. The factors include the magnitude of minimum encoding rate and link capacity. With given environment, compare Max-sum PSNR and Max-min fair PSNR for max PSNR, min PSNR, sum PSNR and Jain’s fairness index.
