Partial delivery method with multi-bitrates and resolutions for interactive panoramic video streaming system

摘要

This paper examines delivery methods for the interactive panoramic video delivery service that enables users to watch high-resolution panoramic images beyond HD quality using available network resources and the TV sets in users' homes. We propose a new data format based on Multiview Video Coding and a partial delivery method that permits even restricted bandwidth networks to support high-quality partial panoramic video transmission. We show the experiments conducted on the proposed partial delivery method. The results show that two types of the proposed method can achieve higher subjective video quality than the deliver-all method when the ROI (Region Of Interest) moves.
