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.

High Quality Video

Situation awareness in surveillance systems benefits from high-quality video streaming service. This is even more important considering military systems, in which delays in image transmission may have a significant impact on the decision-making process. However, in order to deliver high-quality video streaming service, the required network infrastructure may be prohibitively complex, or even completely impossible to deploy, if mobile data providers are considered. Moreover, the demand for high network throughput poses extra requirements on the network. Considering this context, this paper addresses the problem of highly mobile networks composed of unmanned aerial vehicles (UAVs) as data providers of a military surveillance system. The proposed approach to tackle the problem is based on a Software Defined Networking (SDN) approach aiming at providing the best routes to deliver the data, enhancing the end-user quality of experience. An extensive experimental campaign was performed by means of simulations and the acquired results provide solid evidence of the usefulness of this proposal.

The Impact

The majority of internet traffic is video content. This drives the demand for video compression in order to deliver high quality video at low target bitrates. This paper investigates the impact of adjusting the rate distortion equation on compression performance. An constant of proportionality, k, is used to modify the Lagrange multiplier used in H.265 (HEVC). Direct optimisation methods are deployed to maximise BD-Rate improvement for a particular clip. This leads to up to 21% BD-Rate improvement for an individual clip. Furthermore we use a more realistic corpus of material provided by YouTube. The results show that direct optimisation using BD-rate as the objective function can lead to further gains in bitrate savings that are not available with previous approaches.

Communication Methods

The rise of short videos in the Post-epidemic era have caused the migration of Internet traffic to visual content. This new form of media based on communication technology and algorithm technology can arouse more emotional resonances of audiences, which promotes the formation of a Visual Public opinion field. The emergence of this public opinion field not only increases the risk of public opinion crises such as rumors and extreme views, but also points out the current direction of public opinion governance, and shows the importance of making good use of visual communication methods. Based on this, mainstream media needs to integrate and lead the visual public opinion field by entering the video media platform, producing high-quality video content, and reconstructing the visual public opinion ecology; the competent authority should do a good job in the visual public opinion field from the three aspects of ideology, technology and content. Supervision and governance work will promote a good long-term growth of visual public opinion field.

High Quality Video

Delivering high quality video content to customers is now expected to be one of the driving forces for the evolution of the Internet as it can be deployed in many niches of the emerging e-market. This chapter presents an originally developed Video Retrieval application with its unique features including a flexible user interface based on HTTP browser for content querying and browsing, support for both unicast and multicast addressing and a user-oriented control of QoS of video streaming in Integrated Services IP networks. The remaining part of the chapter is devoted to some selected methods of information systems’ modelling requested for the prediction of a system performance and an influence of different control mechanisms on quality of service perceived by end users.

The Relationship

V Live is a live-streaming service made by South Korean IT company in August 2015. The service provides diverse video contents specific to entertainment content. Most of V Live users are K-pop fans, and they actively express emotions on V Live content by writing comments, pressing “hearts”, and sharing video content. Based on Uses and Gratifications theory, this study investigated why people use live streaming service, and the factors influencing users’ viewing behavior in live streaming. We conducted an in-depth interview with V Live users. Based on the results of the interview, an online survey was conducted. As a result, six factors—“Interpersonal relationship motivation”, “Social presence motivation”, “Celebrity support motivation”, “Celebrity presence motivation”, “Social interaction motivation”, and “Differentiation motivation”—were derived as motivations to use V Live. While “Social presence motivation” and “Differentiation motivation” among V Live use motivations that have been shown to mediate the relationship between fans’ fanship and V Live viewing time, all motivations using V Live have been shown to mediate the relationship between fans’ fanship and V Live viewing participation.

Abr Algorithm

Video clients employ HTTP-based adaptive bitrate (ABR) algorithms to optimize users’ quality of experience (QoE). ABR algorithms adopt video quality based on the network conditions during playback. The existing state-of-the-art ABR algorithms ignore the fact that video streaming services deploy segment durations differently in different services, and HTTP clients offer distinct buffer sizes. The existing ABR algorithms use fixed control laws and are designed with predefined client/server settings. As a result, adaptation algorithms fail to achieve optimal performance across a variety of video client settings and QoE objectives. We propose a buffer- and segment-aware fuzzy-based ABR algorithm that selects video rates for future video segments based on segment duration and the client’s buffer size in addition to throughput and playback buffer level. We demonstrate that the proposed algorithm guarantees high QoE across various video player settings and video content characteristics. The proposed algorithm efficiently utilizes bandwidth in order to download high-quality video segments and to guarantee high QoE. The results from our experiments reveal that the proposed adaptation algorithm outperforms state-of-the-art algorithms, providing improvements in average video rate, QoE, and bandwidth utilization, respectively, of 5% to 18%, about 13% to 30%, and up to 45%.
