Traditional adaptive video streaming approaches rely on the over-provisioning of resources leading to a fixed bitrate ladder, which is often inefficient for the heterogeneous set of use cases and video content. Although dynamic approaches like per-title encoding optimize the bitrate ladder for each video, they mainly target video-on-demand to avoid latency and fail to address energy consumption. In this paper, we present LiveESTR, a method for building a quality- and energy-aware bitrate ladder for live video streaming. LiveESTR eliminates the need for exhaustive video encoding processes on the server side, ensuring that the bitrate ladder construction process is fast and energy efficient. A lightweight model for multi-label classification, along with a lookup table, is utilized to estimate the optimized resolution-bitrate pair in the bitrate ladder. Furthermore, both spatial and temporal resolutions are supported to achieve high energy savings while preserving compression efficiency. Therefore, a tunable parameter <inline-formula> <tex-math>$lambda $ </tex-math></inline-formula> and a threshold <inline-formula> <tex-math>$tau $ </tex-math></inline-formula> are introduced to balance the trade-off between compression/quality and energy efficiency. Experimental results show that LiveESTR reduces the encoder and decoder energy consumption by 74.6 % and 29.7 %, with only a 2.1 % increase in Bjøntegaard Delta Rate (BD-Rate) compared to traditional per-title encoding. Furthermore, it is shown that by increasing <inline-formula> <tex-math>$lambda $ </tex-math></inline-formula> to prioritize video quality, LiveESTR achieves 2.2 % better compression efficiency in terms of BD-Rate while still reducing decoder energy consumption by 7.5 %.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"15 1","pages":"83-93"},"PeriodicalIF":3.7,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10877851","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inference of the entropy models and the sequential nature of the entropy coding both incur high time complexity. Meanwhile, the neural network-based entropy models usually involve floating-point computations, which incur inconsistent probability estimation and decoding failure in different platforms. We address these limitations by introducing an efficient and cross-platform entropy coding method, chain coding-based latent compression (CC-LC), into learned image compression. First, we leverage the classic chain coding and carefully design a block-based entropy coding procedure, significantly reducing the number of coding symbols and thus the coding time. Second, since CC-LC is not based on neural networks, we propose a rate estimation network as a surrogate of CC-LC during the end-to-end training. Third, we alternately train the analysis/synthesis networks and the rate estimation network for the rate-distortion optimization, making the learned latent fit CC-LC. Experimental results show that our method achieves much lower time complexity than the other learned image compression methods, ensures cross-platform consistency, and has comparable compression efficiency with BPG.

Integrating SR systems with Deep Neural Networks (DNNs) is a widely adopted method for leveraging faster and improved image reconstruction. However, the real-time computational demands, extensive energy overhead and the huge memory footprints associated with DNN-based SR systems limit their throughput and scalability. Field-programmable gate arrays (FPGAs) present a viable and promising solution for exploring the structure and architecture of SR systems due to their reconfigurable nature and parallel computing capabilities. The existing FPGA-based solutions can effectively reduce the computational latency in SR systems, they often result in higher resource and energy consumption. Besides, the traditional SR techniques generally focus on either upscaling or downscaling images or videos without offering any scaling reconfigurability. To address these limitations, this paper introduces <italic>BiDSRS+</i>, a novel FPGA based resource-efficient and reconfigurable real-time SR system using modified bicubic interpolation method. In addition, <italic>BiDSRS+</i> supports both upscaling and downscaling of images and videos, enhancing its versatility. Evaluations conducted on the Xilinx ZCU 102 FPGA board reveal substantial resource savings, with reductions of 44x LUT, 31x BRAM, and 35x DSP utilization compared to state-of-the-art DNN-based SR systems, albeit with a trade-off in throughput of 0.5x. Furthermore, when compared to leading algorithm-based SR systems, <italic>BiDSRS+</i> achieves reductions of 5.8x LUT, 1.75x BRAM, and 2.3x Power consumption, without compromising the throughput. Due to its high resource efficiency and reconfigurability with a throughput of 4K@60 FPS, <italic>BiDSRS+</i> offers significant advantages in promoting sustainable and energy-efficient green video communication.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"15 1","pages":"120-132"},"PeriodicalIF":3.7,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the rising in-memory technologies are <italic>Memristors</i>, which are resistors capable of memorizing state based on an applied voltage, making them useful for storage and computation. Another emerging computing paradigm is <italic>Approximate Computing</i>, which allows for errors in calculations to in turn reduce die area, processing time and energy consumption. In an attempt to combine both concepts and leverage their benefits, we propose the memristor-based adaptive approximate adder <italic>ApprOchs</i> - which is able to selectively compute segments of an addition either approximately or exactly. ApprOchs is designed to adapt to the input data given and thus only compute as much as is needed, a quality current State-of-the-Art (SoA) in-memory adders lack. Despite also using OR-based approximation in the lower k bit, ApprOchs has the edge over S-SINC because ApprOchs can skip the computation of the upper n-k bit for a small number of possible input combinations (22k of 22n possible combinations skip the upper bits). Compared to SoA in-memory approximate adders, ApprOchs outperforms them in terms of energy consumption while being highly competitive in terms of error behavior, with moderate speed and area efficiency. In application use cases, ApprOchs demonstrates its energy efficiency, particularly in machine learning applications. In MNIST classification using Deep Convolutional Neural Networks, we achieve 78.4% energy savings compared to SoA approximate adders with the same accuracy as exact adders at 98.9%, while for k-means clustering, we observed a 69% reduction in energy consumption with no quality drop in clustering results compared to the exact computation. For image blurring, we achieve up to 32.7% energy reduction over the exact computation and in its most promising configuration (<inline-formula> <tex-math>$k=3$ </tex-math></inline-formula>), the ApprOchs adder consumes 13.4% less energy than the most energy-efficient competing SoA design (S-SINC+), while achieving a similarly excellent median image quality at 43.74dB PSNR and 0.995 SSIM.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"15 1","pages":"105-119"},"PeriodicalIF":3.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present an in-depth study of the compression performance and energy efficiency of HDR video encoding using High-Efficiency Video Coding (HEVC). In addition to using a native 10-bit HDR encoding configuration as a reference, we explore whether applying tone mapping to an 8-bit representation before encoding can result in additional bitrate and energy savings without compromising visual quality. The main contributions of this work are as follows: 1) a detailed evaluation of four HDR video encoding configurations, three of which leverage tone mapping techniques, 2) a comprehensive experimental setup involving over 15,000 individual encodings across three open-source HEVC encoders (Kvazaar, x265, and SVT-HEVC) and multiple presets, 3) the use of two advanced perception-based metrics for BD-rate calculations, one of which is specifically tailored to capture colour distortions and 4) an open-source dataset consisting of all experimental results for further research. Among the three tone-mapping configurations tested, our findings show that a simple bit-shifting approach can achieves significant reductions in both bitrate and energy consumption compared to the native 10-bit HDR encoding configuration. This research aims to lay an initial foundation for understanding the balance between coding efficiency and energy consumption in HDR video encoding, offering valuable insights to guide future advancements in the field.","PeriodicalId":48827,"journal":{"name":"IEEE Journal on Emerging and Selected Topics in Circuits and Systems","volume":"15 1","pages":"31-43"},"PeriodicalIF":3.7,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10851260","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
