“…The authors provided three solutions for transmitting 4k video content with the lowest bitrate being 4.59 Gb/s. The authors in [8][9][10][11] provided alternative solutions for streaming 4k video content using JPEG 2000 codec. Their solutions discussed the bi-directional of 4k video content at 60Hz using JPEG 2000 multi-layer, scalable coding and a bandwidth of up to 700Mb/s.…”

The Internet of things (IoT) has received a great deal of attention in recent years, and is still being approached with a wide range of views. At the same time, video data now accounts for over half of the internet traffic. With the current availability of beyond high definition, it is worth understanding the performance effects, especially for real-time applications. High Efficiency Video Coding (HEVC) aims to provide reduction in bandwidth utilisation while maintaining perceived video quality in comparison with its predecessor codecs. Its adoption aims to provide for areas such as television broadcast, multimedia streaming/storage, and mobile communications with significant improvements. Although there have been attempts at HEVC streaming, the literature/implementations offered do not take into consideration changes in the HEVC specifications. Beyond this point, it seems little research exists on real-time HEVC coded content live streaming. Our solution fills this current gap in enabling compliant and real-time networked HEVC visual applications. This is done implementing a technique for real-time HEVC encapsulation in MPEG-2 Transmission Stream (MPEG-2 TS) and HTTP Live Streaming (HLS), thereby removing the need for multi-platform clients to receive and decode HEVC streams. It is taken further by evaluating the transmission of 4k UHDTV HEVC-coded content in a typical wireless environment using both computers and mobile devices, while considering well-known factors such as obstruction, interference and other unseen factors that affect the network per- formance and video quality. Our results suggest that 4kUHD can be streamed at 13.5 Mb/s, and can be delivered to multiple devices without loss in perceived quality.

“…To provide the desired level of interactivity and to limit end-to-end latencies of the user communication, while avoiding substantial quality loss, these environments often build upon streams of high-bandwidth media with low compression ratios [19,50,55] that are transmitted between the components of the environment. Bitrates of such media streams are often comparable even to capacities of current highestspeed network links.…”

Data transfer planning with tree placement for collaborative environments

Latency-sensitive data distribution and media streaming is a part of many network-centric applications. Based on our previous practical experiences with interactive high-quality media distribution and orchestration of network-centric collaborative environments, we have developed an automated planner for media stream distribution in environments where bandwidth of streams is comparable to capacities of network links. We have successfully adopted methods of constraint programming to deal with this problem. We provide a new comprehensive description of the constraint model which builds upon basic algebraic description we have published earlier. To formulate the model, a tree placement problem is proposed and a new corresponding variant of the link-based model for traffic placement problem is applied. We prove correctness of the proposed constraint satisfaction problem to present validity of included constraints with respect to the desired functionality of planning. An evaluation of the implemented solver is presented on a number of experimental problems to show effectiveness of the formulation. Importantly, the solver is a part of an application middleware called CoUniverse, which is pioneering orchestration of component-based interactive collaborative environments in 284 Constraints (2011) 16:283-316 a number of global demonstrations and projects. Both flexibility of the described model as well as generality of other parts of the CoUniverse framework allowed it to be one of very few early adopters of bandwidth-on-demand services for advanced high-bandwidth applications.

“…When designed for multi-point collaborative environments, multi-point data distribution needs to be ensured. Native network multicast has turned to perform less then acceptably in many cases and thus systems like Flexcast [1] or reflectors [2] have been developed. In this paper, we focus on a parallel reflector-based system called distributed Active Element (AE) for synchronous multimedia data distribution and processing [4], [5], which allows distribution of high bandwidth streams using parallel processing on tightly coupled commodity computer clusters.…”

Abstract-In this paper, we propose a distributed Active Element for tightly coupled cluster environment, suitable for distribution of large bandwidth data that exceed capacity of every single node in the cluster. This approach utilizes the fact that real-time multimedia transmission systems relying on nonguaranteed protocols like UDP need to handle limited packet reordering on their own. We describe the Fast Circulating Token protocol, which enables imposing even stricter bound on the outbound packet reordering. The whole system is examined on 10GE testbed and shows very good performance. The FCT provides expected improvement, making the packet reordering comparable to long haul networks.
