Sports multimedia is among the most prominent types of content distributed across social media today, and the retargeting of videos for diverse aspect ratios is essential for a suitable representation on different social media platforms. In this respect, ice hockey is quite challenging due to its agile movement pattern and speed, and because the ma...

The impact of investigative interviews by police and Child Protective Services (CPS) on abused children can be profound, making effective training vital. Quality in these interviews often falls short and current training programs are insufficient in enabling adherence to best practice. We present a system for simulating an interactive environment w...

In the era of digitalization, social media has become an integral part of our lives, serving as a significant hub for individuals and businesses to share information, communicate, and engage. This is also the case for professional sports, where leagues, clubs and players are using social media to reach out to their fans. In this respect, a huge amo...

Training child investigative interviewing skills is a specialized task. Those being trained need opportunities to practice their skills in realistic settings and receive immediate feedback. A key step in ensuring the availability of such opportunities is to develop a dynamic, conversational avatar, using artificial intelligence (AI) technology that...

Cloud gaming requires a reliable and low-latency network, which makes it a very challenging service. Latency strongly affects the gaming QoE and user performance. This chapter proposes delay compensation techniques that can mitigate the negative influence of delay on gaming QoE. The techniques use five game characteristics to adapt the game in a wa...

The growth of multimedia industry increased the competition over delivering a better service to the users. Therefore, it is essential for service providers to evaluate the quality of multimedia services. This chapter provides a short overview about quality assessment on the multimedia and cloud gaming services. The aim of the chapter is to allow th...

Network delay in a real network is often not fixed and it varies over time. Various types of temporal changes can exist in delay such as a variation on the amount of delay also know as jitter, the period when it happens known as serial-position effect, and the time it lasts. Each of them create a different pattern of delay which might have a differ...

This book investigated the impact of delay and delay variations on gaming QoE, where a better understanding of these factors on gaming QoE was provided. A game classification was developed, where it explained the reason why some games are more delay sensitive than others, and the impact of delay on gaming QoE was modeled. In addition, using the ins...

Delay in cloud gaming service comes from various sources, which can negatively impact the gaming QoE and user performance. This chapter, using two datasets investigates the impact of delay on gaming QoE and develops a model to predict the impact of delay on gaming QoE. Furthermore, this chapter investigates the reasons why some games are more sensi...

Soccer is one of the most popular sports globally, and the amount of soccer-related content worldwide, including video footage, audio commentary, team/player statistics, scores, and rankings, is enormous and rapidly growing. Consequently, the generation of multimodal summaries is of tremendous interest for broadcasters and fans alike, as a large pe...

In association football, the development of multimodal summaries is of great importance to both broadcasters and spectators since a large number of viewers choose to follow just the soccer game highlights. The fundamental drive for the development of summarization systems is the requirement to manage huge amounts of data in different formats. By hi...
