Titel
Shifted IDR representations for low delay live DASH streaming using HEVC tiles
Abstract
Dynamic Adaptive Streaming over HTTP (DASH) has gained a lot of popularity in the last years and has become a widespread solution for media delivery. It is mainly used for VoD services but has being also standardized and can be used for live scenarios. Although there has been a lot of work on low delay DASH services, it is still very challenging to cope with network variations. In fact, low delay configurations prevent DASH users from having a large media buffer to cope with network variations and they can easily lead to deadline misses, which results in a service of low Quality of Experience (QoE). In this paper we propose a solution based on HEVC Tiles and an advanced DASH adaptation algorithm that improves drastically the performance by heavily reducing the deadline misses.
