Spatial downsizing impact in the transrating tradeoff for content/context awareness in media network

Abstract : Bitrate control in video content is one of the key features of the emerging content/context aware network. Within the content/context aware network framework, network devices are able to adapt video content to fit network (bandwidth ...) and terminal (screen size ...) constraints. But reducing video spatial resolution for video-to-terminal adaptation also impacts the bitrate of the video which is a video-to-network adaptation. In this paper, we propose a method to evaluate the impact of spatial downsizing as a technique to reduce the video bitrate. We study the tradeoff between traditional bitrate adaptation and spatial downsizing through various use case. Each use case is emulated by experiments. Quality evaluation using SSIM and PSNR ratings is performed.
