HTTP-based delivery for Video on Demand (VoD) has been gaining popularity within recent years. Progressive Download over HTTP, typically used in VoD, takes advantage of the widely deployed network caches to relieve video servers from sending the same content to a high number of users in the same access network. However, due to a sharp increase in the(More)
Media delivery, especially video delivery over mobile channels may be affected by transmission bitrate variations or temporary link interruptions caused by changes in the channel conditions or the wireless interface. In this paper, we present the use of Priority-based Media Delivery (PMD) for Scalable Video Coding (SVC) to overcome link interruptions and(More)
— Real-time video applications, such as video conferencing and video surveillance systems, typically involve the simultaneous transport of multiple video sources to interested parties that consume the content. It may be desirable to mix these multiple source videos into a single video stream at intermediary nodes in the network. This has the advantage of(More)
Video traffic contributes to the majority of data packets transported over cellular wireless. Future broadband wireless access networks based on 3GPP's Long Term Evolution offer mechanisms for optimized transmission with high data rates and low delay. However, especially when packets are transmitted in the LTE downlink and if services are run over-the-top(More)
The media, especially the video delivery over mobile channels may be affected by link outages and transmission bit rate variations due to the actual channel condition and the used wireless interface. In this paper we present the use of Priority-based Transmission Scheduling of SVC media data to overcome link outages and reduction in channel bit rate in(More)
Panoramic streaming is a particular way of video streaming where an arbitrary Region-of-Interest (RoI) of high-spatial resolution videos is transmitted, allowing users to navigate around the video and leading to an immersive experience. Tile based streaming has been proposed in the past and is drawing a lot of attention to provide a solution that scales(More)
