Dash-based approach for delivery of automatic video summaries

The popularity of smart mobile devices has increased both the amount and consumption of media content using mobile devices. This has created a need for services which can provide short summaries of certain content (e.g. highlights of a sport event) efficiently available for end-users. However, the process of video summary creation is usually a quite complex task and an efficient implementation of video summary service would usually need some dedicated hardware. This paper proposes a novel lightweight approach for creation and delivery of video summaries utilizing recently developed DASH technology. The evaluation results indicate that considerable reduction on the delay of video summary generation and delivery can be achieved when compared against the traditional approach which uses transcoding and progressive download for creation and delivery of video summaries.
