About this Research Topic
However, the improvements in network communication do not preclude the presence of possible issues, such as bottleneck links, multi-user ecosystems, varying bandwidth conditions, etc. Therefore, implementing video streaming solutions is fraught with difficulties, including the need for design and optimization advancements to meet Quality of Service (latency, bandwidth, delay, etc.) and Quality of Experience (ease of use, enjoyment, satisfaction etc.) requirements. For the aforementioned reasons, this Research Topic aims to solicit the submissions of original and unpublished research articles that present in-depth fundamental research contributions either from a theoretical or methodological/application perspective containing novel architectures, algorithms, systems, techniques or applications offering new insights and findings in the video streaming field.
Many current and potential future applications depend on high-quality video feeds. From the users' perspective the quality of experience (QoE) is of utmost importance while for the application it is the quality of service (QoS). This places high-quality video feeds in great demand.
However, video streaming performance varies in different network settings and application requirements, possibly varying among heterogeneous devices. Low quality feeds are especially prevalent in the presence of resource constrained links, those with varying bandwidth and where multi-client competition exists at the last-mile. As a consequence, applications and users do not get adequate, consistent and/or high-quality video streams to suit their needs. The goal of this Research Topic is to explore, investigate and propose techniques and methods used to improve video QoS and QoE in next generation networks.
There have been numerous studies at different layers of the ISO/OSI model advancing the QoS and QoE in contemporary networks. However, recent work focuses more on the QoE user experience. Advances include optimization techniques at the different layers and framework/architectural changes in the location and function of video streaming agents. With ongoing progress in communication technologies this field's rapidly changing requirements push the need for novel techniques and methods.
