Coding Time Prediction in H.264/HEVC Transcoding Using Macroblock Sizes
(2019)The continuous customers' demand for higher resolution video led to the development of video coding standards that surpass the limitations of H.264/AVC. Prominent examples in this category include the High Efficiency Video ... -
Evaluation of heterogeneous scheduling algorithms for wavefront and tile parallelism in video coding
(2019)Video is by far the “biggest” Big Data, stretching network and storage capacity to their limits. To handle the situation, video compression has been an active field of study for many years, producing output of huge commercial ... -
A framework for scheduling the encoding of multiple smart user videos
(2016)The ever increasing number of video uploads in social media platforms, together with the incorporation of live video broadcasts and a growing demand for higher video resolution, will likely pose the most significant ... -
A high performance and low power hardware architecture for the transform & quantization stages in H.264
(2009)In this work, we present a hardware architecture prototype for the various types of transforms and the accompanying quantization, supported in H.264 baseline profile video encoding standard. The proposed architecture ... -
Mapping and optimization of the AVS video decoder on a high performance chip multiprocessor
(2010)Modern multimedia workloads provide increased levels of quality and compression efficiency at the expense of substantially increased computational complexity. It is important to leverage the off-the-shelf emerging multi-core ... -
On planning the adoption of new video standards in social media networks: a general framework and its application to HEVC
(2017)In recent years, we have witnessed an explosion in the growth of social media networks, powered by the proliferation of handheld smart devices with high processing capabilities and a plethora of sensors including high-resolution ... -
On the Evaluation of Coarse Grained Parallelism in AV1 Video Coding
(2018)Video compression is arguably one of the most time consuming tasks, especially at high resolutions. For this reason parallelization has been used at various levels: from coarse grained schemes that consider groups of blocks ... -
Performance and power simulation of a functional-unit-network processor with Simplescalar and Wattch
(2015)Loop acceleration is a means to enhance performance of a singleor multiple-issue microprocessor core. A new edge-like processor architecture incorporates a loop accelerator directly in the out-oforder back end of the ... -
Performance evaluation of batch encodings in HEVC using slice level parallelism
(2016)HEVC has emerged as the new video standard to replace H.264/AVC. Although the new standard is able to achieve significantly higher compression ratios compared to the older one, it entails high computational demands. To ... -
A personalized audio server using MPEG-7 and MPEG-21 standards
(2010)This paper presents a semantic model which delivers personalized audio information. The personalization process is automated and decentralized. The metadata which support personalization are separated in two categories: ... -
Slice-based parallelization in HEVC encoding: Realizing the potential through efficient load balancing
(2017)The new video coding standard HEVC (High Efficiency Video Coding) offers the desired compression performance in the era of HDTV and UHDTV, as it achieves nearly 50% bit rate saving compared to H.264/AVC. To leverage the ...
