HTTP Adaptive Streaming (HAS) is the predominant technique to deliver video contents across the Internet with the increasing demand of its applications. With the evolution of videos to deliver more immersive experiences, such as their evolution in resolution and framerate, highly efficient video compression schemes are required to ease the burden on the delivery process. While AVC/H.264 still represents the most adopted codec, we are experiencing an increase in the usage of new generation codecs (HEVC/H.265, VP9, AV1, VVC/H.266, etc.). Compared to AVC/H.264, these codecs can either achieve the same quality besides a bitrate reduction or improve the quality while targeting the same bitrate. In this paper, we propose a Mixed-Binary Linear Programming (MBLP) model called Multi-Codec Optimization Model at the edge for Live streaming (MCOM-Live) to jointly optimize (i) the overall streaming costs, and (ii) the visual quality of the content played out by the end-users by efficiently enabling multi-codec content delivery. Given a video content encoded with multiple codecs according to a fixed bitrate ladder, the model will choose among three available policies, i.e., fetch, transcode, or skip, the best option to handle the representations.
We compare the proposed model with traditional approaches used in the industry. The experimental results show that our proposed method can reduce the additional latency by up to 23% and the streaming costs by up to 78%, besides improving the visual quality of the delivered segments by up to 0.5 dB, in terms of PSNR.
Requiring only half the bitrate of its predecessor, the new standard – HEVC or H.265 – will significantly reduce the need for bandwidth and expensive, limited spectrum. HEVC (H.265) will enable the launch of new video services and in particular ultra HD television (UHDTV).
State-of-the-art video compression techniques – HEVC/H.265 – can reduce the size of raw video by a factor of about 100 without any noticeable reduction in visual quality. With estimates indicating that compressed real-time video accounts for more than 50 percent of current network traffic, and this figure is set to rise to 90 percent within a few years, HEVC/H.265 will be a welcome relief for network operators.
New services, devices and changing viewing patterns are among the factors contributing to the growth in video traffic as people watch more and more traditional TV and video-streaming services on their mobile devices.
Ericsson has been heavily involved in the standardization of HEVC since it began in 2010, and this Ericsson Review article highlights some of the contributions that have led to the compression efficiency offered by HEVC.

H2B2VS (HEVC hybrid broadcast broadband video services) – Building innovative...Raoul Monnier
Broadcast and broadband networks continue to be separate worlds in the video consumption business. Some initiatives such as HbbTV have built a bridge between both worlds, but its application is almost limited to providing links over the broadcast channel to content providers’ applications such as Catch-up TV services. When it comes to reality, the user is using either one network or the other.
H2B2VS is a Celtic-Plus project aiming at exploiting the potential of real hybrid networks by implementing efficient synchronization mechanisms and using new video coding standard such as High Efficiency Video Coding (HEVC). The goal is to develop successful hybrid network solutions that enable value added services with an optimum bandwidth usage in each network and with clear commercial applications. An example of the potential of this approach is the transmission of Ultra-HD TV by sending the main content over the broadcast channel and the required complementary information over the broadband network. This technology can also be used to improve the life of handicapped persons: Deaf people receive through the broadband network a sign language translation of a programme sent over the broadcast channel; the TV set then displays this translation in an inset window.
One of the most important contributions of the project is developing and testing synchronization methods between two different networks that offer unequal qualities of service with significant differences in delay and jitter.
In this paper, the main technological project contributions are described, including SHVC, the scalable extension of HEVC and a special focus on the synchronization solution adopted by MPEG and DVB. The paper also presents some of the implemented practical use cases, such as the sign language translation described above, and their performance results so as to evaluate the commercial application of this type of solution.
This paper deals with the overview of latest video coding standard High-Efficiency Video
Coding (HEVC). Also this work presents a performance comparison of the two latest video coding
standards H.264/MPEG-AVC and H.265/MPEG-HEVC. According to the experimental results, which
were obtained for a whole test set of video sequences by using similar encoding configurations,
H.265/MPEG-HEVC provides significant average bit-rate savings of around 40%.
Keywords: - CABAC, CAVLC, H.264/AVC, HEVC PSNR and SBAC.

Data processing, exploitation, and dissemination (PED) is mission-critical for warfighters and analysts. Video data in particular can yield vital information and context, and government agencies spend millions of dollars annually gathering it. Yet extracting the full intelligence potential of the data during the PED process has proven to be a challenge due to error-prone and bandwidth-constrained networks, as well as overall poor image quality. Join the team that built the glass-to-glass workflow for the USD(I)-governed and NGA-led 2018 Enterprise Challenge event, showcasing HD contribution feeds using ruggedized small form factor encoders in the field, ingesting feeds into the AWS Cloud for packaging, and delivering to multiscreen devices to improve intelligence gathering for the warfighter. Learn about best practices, hurdles in architecting the solution, and how these technologies are refining the intelligence, surveillance, and reconnaissance (ISR) landscape.

VEED: Video Encoding Energy and CO2 Emissions Dataset for AWS EC2 instancesAlpen-Adria-Universität
Video streaming constitutes 65 % of global internet traffic, prompting an investigation into its energy consumption and CO2 emissions. Video encoding, a computationally intensive part of streaming, has moved to cloud computing for its scalability and flexibility. However, cloud data centers’ energy consumption, especially video encoding, poses environmental challenges. This paper presents VEED, a FAIR Video Encoding Energy and CO2 Emissions Dataset for Amazon Web Services (AWS) EC2 instances. Additionally, the dataset also contains the duration, CPU utilization, and cost of the encoding. To prepare this dataset, we introduce a model and conduct a benchmark to estimate the energy and CO2 emissions of different Amazon EC2 instances during the encoding of 500 video segments with various complexities and resolutions using Advanced Video Coding (AVC)
and High-Efficiency Video Coding (HEVC). VEED and its analysis can provide valuable insights for video researchers and engineers to model energy consumption, manage energy resources, and distribute workloads, contributing to the sustainability of cloud-based video encoding and making them cost-effective. VEED is available at Github.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
