In the past decade, there has been a significant increase in the demand for online video services. Recent studies have revealed that production and use of devices for online video tasks contribute to more than 1% of global greenhouse gas emissions, highlighting the need for research on power consumption and energy efficiency of these devices during video streaming to ensure sustainable use. Over-the-top providers are striving to offer high-quality streaming experiences that meet user expectations. It is important to note that both energy consumption and Quality of Experience (QoE) depend on the same system parameters; therefore, it is necessary to take a joint view when evaluating these factors. In this paper, the authors conduct an analysis of both end-user power efficiency and QoE in a video streaming service. They utilize a crowdsourced dataset consisting of 447,000 streaming events from YouTube to estimate both power consumption and perceived quality. The power consumption is modeled based on previous work which has been extended to predict the power usage of different devices and codecs. The user-perceived QoE is estimated using a standardized model. The results indicate that making intelligent choices regarding streaming parameters can optimize both QoE and power efficiency for end-user devices; suggesting users can enjoy high-quality streaming experiences while minimizing their device's energy consumption by selecting appropriate settings. Additionally, the paper discusses limitations of their approach and identifies directions for future research; addressing these limitations and exploring further avenues of investigation can continue to improve our understanding of energy consumption and QoE in video streaming services. Overall, this study sheds light on the importance of considering both power efficiency and QoE when designing and evaluating video streaming services; providing valuable insights into how these two factors can be optimized simultaneously towards more sustainable use of technology in this rapidly growing industry.
There is a lot of demand for watching videos online. Using devices to watch videos online can harm the environment. We need to study how much energy these devices use when streaming videos. Companies that offer video streaming services want to make sure their videos are high-quality. The amount of energy used and the quality of the video depend on the same things. Researchers looked at how much energy people use when watching videos and how they feel about the quality. They used information from many people to estimate how much energy is used and how good the videos are. By making smart choices, we can have good quality videos while using less energy. It's important to think about both energy efficiency and video quality when making video streaming services."

The Growing Demand for Online Video Services and its Impact on Energy Consumption
In the past decade, there has been a significant increase in the demand for online video services. This surge in popularity has led to an increased production of devices used to stream videos, resulting in more than 1% of global greenhouse gas emissions being attributed to these activities. As such, it is essential that research be conducted into power consumption and energy efficiency of streaming devices so as to ensure sustainable use.
Power Efficiency vs Quality of Experience (QoE)
Over-the-top providers are striving to offer high-quality streaming experiences that meet user expectations while also minimizing their device's energy consumption. It is important to note that both energy consumption and QoE depend on the same system parameters; therefore, it is necessary to take a joint view when evaluating these factors.
Analysis of Power Efficiency and QoE in Video Streaming Service
In this paper, the authors conduct an analysis of both end-user power efficiency and QoE in a video streaming service by utilizing a crowdsourced dataset consisting of 447,000 streaming events from YouTube. The power consumption was modeled based on previous work which was extended to predict the power usage of different devices and codecs; while user-perceived QoE was estimated using a standardized model.
Optimizing Power Efficiency & Quality Of Experience Simultaneously
The results indicate that making intelligent choices regarding streaming parameters can optimize both QoE and power efficiency for end-user devices; suggesting users can enjoy high-quality streaming experiences while minimizing their device's energy consumption by selecting appropriate settings. Additionally, the paper discusses limitations of their approach and identifies directions for future research; addressing these limitations and exploring further avenues of investigation can continue to improve our understanding of energy consumption and QoE in video streaming services.
Conclusion
Overall, this study sheds light on the importance of considering both power efficiency and QoE when designing and evaluating video streaming services; providing valuable insights into how these two factors can be optimized simultaneously towards more sustainable use of technology in this rapidly growing industry.
In the past decade, we have witnessed an enormous growth in the demand for online video services. Recent studies estimate that nowadays, more than 1% of the global greenhouse gas emissions can be attributed to the production and use of devices performing online video tasks. As such, research on the true power consumption of devices and their energy efficiency during video streaming is highly important for a sustainable use of this technology. At the same time, over-the-top providers strive to offer high-quality streaming experiences to satisfy user expectations. Here, energy consumption and QoE partly depend on the same system parameters. Hence, a joint view is needed for their evaluation. In this paper, we perform a first analysis of both end-user power efficiency and Quality of Experience of a video streaming service. We take a crowdsourced dataset comprising 447,000 streaming events from YouTube and estimate both the power consumption and perceived quality. The power consumption is modeled based on previous work which we extended towards predicting the power usage of different devices and codecs. The user-perceived QoE is estimated using a standardized model. Our results indicate that an intelligent choice of streaming parameters can optimize both the QoE and the power efficiency of the end user device. Further, the paper discusses limitations of the approach and identifies directions for future research.
