Abstract:

Abstract The practice of live streaming video games is becoming increasingly popular worldwide (Taylor 2018). Live streaming represents more than entertainment; it is expanding the practice of turning play into work. Though it is commonly misconstrued as “just playing video games,” live streaming requires a great deal of behind-the-scenes labor, especially for women, who often face additional challenges as professionals within video game culture (AnyKey 2015). In this article, we shed light on one important aspect of the gendered work of video game live streaming: emotional labor. To do so, we present observations and insights drawn from our analysis of instructional videos created by women live streamers and posted to YouTube. These videos focus on “tips and tricks” for how aspiring streamers can become successful on Twitch. Building from these videos, we articulate the various forms that emotional labor takes for video game live streamers and the gendered implications of this labor. Within these videos, we identify key recurring topics, such as how streamers work to cultivate feelings in viewers, perform feelings, manage their own feelings, and use feelings to build personal brands and communities for their streams. Drawing from existing work on video games and labor, we move this scholarly conversation in important new directions by highlighting the role of emotional labor as a key facet of video game live streaming and insisting on the importance of attending to how the intersection of play and work is tied to identity.

Abstract:

When conducting classroom observations, researchers are often confronted with the decision of whether to conduct observations live or by using pre-recorded video. The present study focuses on comparing and contrasting observations of live and video administrations of the Classroom Assessment Scoring System–PreK (CLASS-PreK). Associations between versions, mean differences, reliability, and predictive validity were examined. Results generally indicated high correlations between versions. Video codes were slightly lower on average than live codes. Reliability was generally acceptable in terms of Cronbach’s alpha, but multigroup confirmatory factor models suggested some differences between observation types. Finally, CLASS scores based on each observation type indicated some predictive validity of children’s academic achievement, but no observation type was uniformly better. The discussion focuses on why the codes might differ and the implications of those differences.

Abstract:

We introduce the task of automatic live commenting. Live commenting, which is also called “video barrage”, is an emerging feature on online video sites that allows real-time comments from viewers to fly across the screen like bullets or roll at the right side of the screen. The live comments are a mixture of opinions for the video and the chit chats with other comments. Automatic live commenting requires AI agents to comprehend the videos and interact with human viewers who also make the comments, so it is a good testbed of an AI agent’s ability to deal with both dynamic vision and language. In this work, we construct a large-scale live comment dataset with 2,361 videos and 895,929 live comments. Then, we introduce two neural models to generate live comments based on the visual and textual contexts, which achieve better performance than previous neural baselines such as the sequence-to-sequence model. Finally, we provide a retrieval-based evaluation protocol for automatic live commenting where the model is asked to sort a set of candidate comments based on the log-likelihood score, and evaluated on metrics such as mean-reciprocal-rank. Putting it all together, we demonstrate the first “LiveBot”. The datasets and the codes can be found at https://github.com/lancopku/livebot.

Abstract:

Methods for No-Reference Video Quality Assessment (NR-VQA) of consumer-produced video content are largely investigated due to the spread of databases containing videos affected by natural distortions. In this work, we design an effective and efficient method for NR-VQA. The proposed method exploits a novel sampling module capable of selecting a predetermined number of frames from the whole video sequence on which to base the quality assessment. It encodes both the quality attributes and semantic content of video frames using two lightweight Convolutional Neural Networks (CNNs). Then, it estimates the quality score of the entire video using a Support Vector Regressor (SVR). We compare the proposed method against several relevant state-of-the-art methods using four benchmark databases containing user generated videos (CVD2014, KoNViD-1k, LIVE-Qualcomm, and LIVE-VQC). The results show that the proposed method at a substantially lower computational cost predicts subjective video quality in line with the state of the art methods on individual databases and generalizes better than existing methods in cross-database setup.

Abstract:

Broadcasting schemes, such as the fast broadcasting and harmonic broadcasting schemes, significantly reduce the bandwidth requirement of video-on-demand services. In the real world, some history events are very hot. For example, every year in March, thousands of people connect to Internet to watch the live show of Oscar Night. Such actions easily cause the networks contested. However, the schemes mentioned previously cannot alleviate the problem because they do not support live broadcasting. In this paper, we analyze the requirements for transferring live videos. Based on the requirements, a time skewing approach is proposed to enable the broadcasting schemes to support live broadcasting. However, the improved schemes require extra bandwidth for live broadcasting once the length of live shows exceeds the default. Accordingly, we proposed a scalable binomial broadcasting scheme to transfer live videos using constant bandwidth by increasing clients’ waiting time. When the scheme finds that the length of a video exceeds the default, it doubles the length of to-be-played segments and then its required bandwidth is constant.

Abstract:

Naver V Live, a South Korean live-streaming service, showcases video contents specific to the entertainment industry, such as K-pop and music. On V Live, K-pop stars and their fans can interact directly in a natural way, and V Live provides high-quality video content with novel topics. This study has identified key characteristics of video content that affect its popularity. A total of 620 video contents of five leading Star channels were classified on the basis of production company, type of video content, and whether it was live-streamed or not. The popularity of video content was measured by the number of comments, hearts, and views. To control potential bias, additional variables were set as control variables—such as the number of channel subscribers, mini-album sales, if the video content was previewed, and cumulative number of days since the video content was uploaded. For analysis, a hierarchical linear regression was conducted. The findings suggest future directions in video content planning.

Abstract:

With the development and popularization of the Internet and the rise of various live broadcast platforms, digital videos have penetrated into all aspects of people’s life. At the same time, all kinds of pirated videos are also flooding the Internet, which seriously infringe the rights and interests of video copyright owners and hinder the healthy development of the video industry. Therefore, robust video watermarking algorithms for copyright protection have emerged as these times require. In this paper, we review robust video watermarking algorithms for copyright protection based on original videos and compressed videos. Basic models and properties of video watermarking algorithms are described, and the evaluation indexes corresponding to each property are also introduced. To help researchers understand various existing robust watermarking algorithms quickly, some basic information and the quantitative estimation of several performances are analyzed and compared. Finally, we discuss the challenges in the research of robust video watermarking algorithms, and give possible development directions for the future.

Abstract:

World is networked through internet today. There are various mobile Applications, which help people in many different ways, based on the purpose of the application. Due to the pandemic lockdown, now-a-days, the classes are conducted online, through modes like, video lectures and video conferencing. Apart from the forced school environment, one can create their own environment to study through online classes. Apart from the established online courses that already have study material and subtitles, the live classes for under graduate students, who begin to explore online education, get the first blow in understanding and educating themselves. Many students find it difficult to listen to lectures through video conferencing because of a cluster of students with different proficiency levels. In a classroom scenario, with the use of blackboard method or power-point presentation, the students somehow get the idea of the subject. That way, if not by listening to the teacher, visual aids help the students to grasp in a better fashion. The purpose of this study is to propose the development of a mobile application, to reduce the difficulties in listening lectures online. The application might act as a caption provider in the video lecture that helps the students to comprehend the subject better. This study is based on a survey taken among 100 undergraduate students from a particular institution in India, to enquire the hardships and hurdles of learning through online lectures. The result of the analysis provided the preference of captioned videos in video lectures for enhancing the purpose of online lectures. This study tries to prove the hardships of non-native speakers of English, while attending video lectures and providing a solution to the aforementioned, based on the survey, by implementing the idea of a mobile application to provide captions, during the live lecture.

Abstract:

This study investigated whether a video of a natural landscape would be more effective for restoration, including attention restoration and recovery from stress, when perceived as live rather than recorded. In total, 60 participants undertook attention-expending and stress inducing tasks, before being randomly assigned to one of three conditions (perceived live video, recorded video, and control). Attention recovery was assessed using Digit Span Backwards (DSB) and the Necker Cube Pattern Control (NCPC) pre- and post-condition, while stress was measured via skin conductivity, heart rate, and heart rate variability. We found that only participants in the live group significantly improved on the NCPC, whereas stress recovery was similar for both perceived live and recorded groups. Our findings suggest that a perceived live stream of nature may allow for greater cognitive inhibition, an important aspect of learning, whereas both perceived live and recorded videos effectively reduced sympathetic stress responses.

Abstract:

Today, the lecture class as a format for higher education is under attack more than ever. This article addresses the research question of how lectures can be modernized and revitalized through new uses of digital technology—in particular, video. Critics of lecturing have for a long time observed that lecture classes can be weak on student engagement and motivation to attend class. This article introduces one way to help modernize and revitalize the live lecture class session, a new conceptualization of the instructor-created video. Instructor-created videos are defined and distinguished from current hybrid and alternative forms of technology integration that are proliferating in higher education such as flipped and blended classrooms. Many, if not most, videos used in lectures are “third party videos” (made by others), whereas instructor-created videos are “first party videos.” The author develops and defines the concept of VIDS (Videos Instructor Designed and Starring). VIDS examples illustrate the concept from the author’s experience in a course with 158 students. Student feedback based on survey results is positive. Suggestions for making better videos are offered based on the implementation experience. The VIDS innovation is discussed within the context of the “crisis of the lecture” and offered as one tool to help modernize and revitalize the live lecture class.

Abstract:

Presentation of information for educational institutions is one of the most important means to introduce the institutions to the public. Raudhatul Athfal (RA) Ar-Rasyid Tanjungpinang needs media that can promote and provide information about the institution, because the number of registrants is decreasing during current years. This research was conducted with the creation of the institution’s profile video that applies elements of live shoot and motion graphics to easily convey information in short duration videos, and to make the profile video look interesting. The stage of making a profile video is starting from taking pictures directly (live shoot), editing to rendering process. Based on the process of designing, implementation, testing and discussion, it can be concluded that this research has been able to produce a profile video that can be used as a promotional mean for attracting new students in 2017/2018 at RA Ar-Rasyid Tanjungpinang. The result shows that 77% of 98 applicants have been informed through video profiles distributed with Videotron.

Este ensayo se basa en un estúdio etnográfico sobre la práctica de los Live-set en los Centros Sociales italianos (Centri Sociali Occapati Autogestiti - CSOA). Los Live-set se caracterizanpor la proyección de imagines al ritmo de música en las fiestas que llaman “free parties”. Experimentando con formas non lineares decomunicación, jugando con la yustaposición y los fragmentos, el Live-set responde a la ética hacker de los CSOA que apropia los signos para subvertir los significados. Esta performance colectiva es una representación cultural de un movimiento que apuesta en formas rizomâticas de organización política. Al mismo tiempo con el Live-set esta contra-cultura celebra y reconfigura su propio imaginario como parte de un movimiento global de resistenciay oposición social.

Abstract:

This project consists of the multidisciplinary analysis of the persuasive strategies used in a regional TV commercial to promote GADIS, a Galician (Spain) supermarket chain. The video, which provoked an overwhelmingly positive reaction within Galician society, strategically appeals nationalistic feelings in order to achieve specific commercial objectives. In this commercial GADIS presents itself as a company that defends local attributes (Galician, Galicians, and ‘Galicianness’) against foreign ones. The speaker, by playing off positive stereotypical features of Galicia and inverting negative ones, builds and conveys a positive image of Galicia which is intended to make Galicians proud of their Galicianness. In order to make the advertisements more acceptable, GADIS praises the Galicians through the use of humor and irony, which serves to mitigate the nationalism presented.

Abstract:

The advent of Cyber-Physical Systems (CPS) has brought a revolutionary change coined as a mixture of information, communication, computation, and control. With applications in smart grid, health monitoring, automatic avionics, distributed robotics, etc., CPS is currently an area of attention among the academia and industry. The advancement of mobile communications and embedded technology has made it possible to build large scale CPS consisting of the interconnection of mobile phones. These devices collect information about the surrounding environment at any time anywhere basis through real-time video capture. Video streaming has proven to be a massive industry that is growing rapidly playing an important role in everyday life. Customer-driven approach wanting best experience with quality has to be the core offering of contemporary scenario. Video streaming is categorized into Video-On-Demand Streaming (VoDS) and Live Video Streaming (LVS) showing the current state-of-art opportunities. Many diverse applications of video streaming are military video surveillance using drones, live sports match player face recognition, on-demand video characters recognition, movie summarization like identifying parts of the movie which are viewed many times by different users, movie and series recognition, motion detection, gesture recognition, image segmentation, etc. This paper introduces an approach to develop video analysis on VoD and LVS using cloud-based services and analyzes the impact of Quality of Experience (QoE), cost, and bandwidth on the cloud. To achieve the best user experience for video streaming and video analysis, Content Delivery Network (CDN) offers the best QoE at various analyzed locations using various cloud providers like Amazon Web Services (AWS) CloudFront, Google Cloud CDN, Azure CDN, Akamai CDN, etc.

Abstract:

In recent years, the rapid development of surveillance information in closed-circuit television (CCTV) has become an indispensable element in security systems. Several CCTV systems designed for video compression and encryption need to improve for the best performance and different security levels. Specially, the advent of 360 video makes the CCTV promising for surveillance without any blind areas. Compared to current systems, 360 CCTV requires the large bandwidth with low latency to run smoothly. Therefore, to improve the system performance, it needs to be more robust to run smoothly. Video transmission and transcoding is an essential process in converting codecs, changing bitrates or resizing the resolution for 360 videos. High-performance transcoding is one of the key factors of real time CCTV stream. Additionally, the security of video streams from cameras to endpoints is also an important priority in CCTV research. In this paper, a real-time transcoding system designed with the ARIA block cipher encryption algorithm is presented. Experimental results show that the proposed method achieved approximately 200% speedup compared to libx265 FFmpeg in transcoding task, and it could handle multiple transcoding sessions simultaneously at high performance for both live 360 CCTV system and existing 2D/3D CCTV system.

Abstract:

Purpose Despite the expansion of e-learning, higher education still involves live lectures, which students often see as “boring”. Lecture classes can be made more engaging and effective by including videos. However, empirical research is yet to report on current video use in lectures, or on student perceptions of and preferences for videos. The purpose of this paper is to fill that knowledge gap. Design/methodology/approach A two-stage mixed-method study used focus groups to gain a rich understanding of student’s video experiences, preferences and the types of videos they are shown. These understandings were utilised in a detailed on-line survey questionnaire, which was completed by a diverse sample of 773 university students, who responded about their recent in-class video experiences. Findings Students report that about 87 per cent of lecture classes included one or more videos. This paper reports on instructor practices, develops a video typology and reports on students’ preferred frequency, type of video, video source, video length and existing vs preferred video integration methods. Practical implications The results provide useful information for educational administrators. Recommendations are made for effective use of videos in lectures by instructors. Originality/value This is the first qualitative and survey research investigating current practice and student perceptions of video use during lecture classes. The authors also conduct the first survey with a broad sample across universities and academic disciplines using the unit of analysis of videos seen per course last week. Typologies of sources of videos, instructional functions, video facilitation techniques and types of videos used during lectures are proposed and then measured.

Abstract:

In July 2016, Diamond Reynolds broadcast the murder of her boyfriend, Philando Castile, by Minnesota police using Facebook Live, a new video-streaming service. Facebook had begun offering live video streaming in order to increase its market share and profits, but Reynolds's video radicalized the platform while also exposing several myths undergirding viewers’ investment in live media, notably the fantasy of shared experience across distance. Reynolds's FB feed is but one of a great many recent videos of black men and women suffering and dying from police violence, yet its platform invests it with a unique feeling of immediacy. This pain and shock might best be described as horror, were it not for the ongoing commercial misuse of that term. This article investigates horror as an affect in order to understand the profound impact that Reynolds's video has had upon U.S. media and politics.

Video playback provides a promising method to study social interactions, and the number of video playback experiments has been growing in recent years. Using videos has advantages over live individuals as it increases the repeatability of demonstrations, and enables researchers to manipulate the features of the presented stimulus. How observers respond to video playback might, however, differ among species, and the efficacy of video playback should be validated by investigating if individuals’ responses to videos are comparable to their responses to live demonstrators. Here, we use a novel foraging task to compare blue tits’ (Cyanistes caeruleus) responses to social information from a live conspecific vs video playback. Birds first received social information about the location of food, and were then presented with a three-choice foraging task where they could search for food from locations marked with different symbols (cross, square, plain white). Two control groups saw only a foraging tray with similar symbols but no information about the location of food. We predicted that socially educated birds would prefer the same location where a demonstrator had foraged, but we found no evidence that birds copied a demonstrator’s choice, regardless of how social information was presented. Social information, however, had an influence on blue tits’ foraging choices, as socially educated birds seemed to form a stronger preference for a square symbol (against two other options, cross and plain white) than the control birds. Our results suggest that blue tits respond to video playback of a conspecific similarly as to a live bird, but how they use this social information in their foraging decisions, remains unclear.

Abstract:

Live streamers’ power and attraction influence consumer behavior. This study focuses on streamer-central formed social capital and the relationship between streamers and audiences on live streaming video platforms (LSVP). First, we explored the impact of trust, norm of reciprocity, and network on social capital formation. Second, we investigated the effect of social capital on streamers’ attributes (attractiveness, expertise, and trustworthiness) and on the audience’s social capital formation. The main findings show that trust and network positively affect social capital. Social capital increases the level of streamers’ attractiveness, expertise, and trustworthiness perceived by the audience, which facilitates sustainable development of the LSVP and the streamer. Perceived streamers’ attractiveness negatively affects social capital formation, while perceived expertise positively affects it. To promote social capital development, streamers and operators of LSVPs should continuously emphasize social capital formation. Moreover, LSVPs should provide audiences with novel and interesting content to enable active networking. For sustainable development of LSVPs, when providing live streaming video services, streamers should deliver content that the audience perceives as based on their expertise rather than on their physical attractiveness.

Abstract:

The purposes of this study were to develop and implement an observational training program and to assess the effects of a video observational training program on video and live observational proficiency. Physical education majors took a pretest in both a video and a live environment to assess observational proficiency. The task was observing children batting and answering questions regarding the critical features of the movement. The students were then placed into either a treatment (n = 12) or a control (n = 11) group. There were no differences between groups on either assessment (p > .05). The treatment group then participated in a video observational training program. After the training, all subjects took a posttest in each environment to assess observational proficiency. The training was found to be effective in improving video observational proficiency (p < .05) but not live observational proficiency (p > .05). These results provide support for the effectiveness of video observational training in developing video observational proficiency but not live observational proficiency.

Abstract:

With the rapid development of Internet technology, live broadcast industry has also flourished. However, in the public network live broadcast platform, live broadcast security issues have become increasingly prominent. The detection of suspected pornographic videos in live broadcast platforms is still in the manual detection stage, that is, through the supervision of administrators and user reports. At present, there are many online live broadcast platforms in China. In mainstream live streaming platforms, the number of live broadcasters at the same time can reach more than 100,000 people/times. Only through manual detection, there are a series of problems such as low efficiency, poor pertinence, and slow progress. This approach is obviously not up to the task requirements of real-time network supervision. For the identification of whether live broadcasts on the Internet contain pornographic content, a deep neural network model based on residual networks (ResNet-50) is proposed to detect pictures and videos in live broadcast platforms. The core idea of detection is to classify each image in the video into two categories: (1) pass and (2) violation. The experiments verify that the network proposed can heighten the efficiency of pornographic detection in webcasts. The detection method proposed in this article can improve the accuracy of detection on the one hand and can standardize the detection indicators in the detection process on the other. These detection indicators have a certain promotion effect on the classification of pornographic videos.

Abstract:

The majority of the traffic in the internet is dedicated to video streaming and its applications. Content Network Networks are good enough in live video streaming. But, implementing live video streaming is not an easy task. Delivery of live video streams can be complicated because of the variety of platforms, network types and streaming formats competing in today's online media services. Every user’s expecting reliable high quality performance with data availability using heterogeneous choices. And it is now tougher than ever to ensure an agreeable, problem less viewing experience on live streaming. Another problem of video streaming is handling security issues, which need fast verification and effective attack resistance. CDN suffers from various security issues, here, a new prototype to perform secure content delivery especially on live video streaming. A lightweight video streaming authentication technique is developed, this authenticates and transmits the data and eliminates the unauthorized access.
