The purpose of this paper is to propose a scheduling method called the “Asynchronous Harmonic Broadcasting Considering Commercial (AHB‐CC)” method, to reduce waiting time for continuous media data broadcasting.

The authors analyze and evaluate the performance of the proposed AHB‐CC method.

The authors confirm that the proposed method gives shorter average waiting times than the conventional methods.

A future direction of this study will involve making a scheduling method where the server concurrently broadcasts data and commercial contents. Also, maximum buffer size needs to be considered.

In general broadcasting systems, the server broadcasts the same data repetitively and clients wait until the first portion of the data is broadcast. Although the server can deliver the data to many clients concurrently, clients have to wait until their desired data are broadcast.

The AHB‐CC method presented in the paper further reduces waiting time by scheduling an effective broadcast that considers the playing time of commercial contents.

The purpose of this paper is to propose a scheduling method called the “Hierarchical Asynchronous Harmonic Broadcasting (H‐AHB)” method, to reduce the waiting time for heterogeneous clients.

The authors analyze and evaluate the performance of the proposed H‐AHB method.

It was confirmed that the proposed method gives shorter average waiting time than the conventional methods.

A future direction of this study will involve making a scheduling method where the server broadcasts multiple videos.

In general broadcasting systems, the server broadcasts the same data repetitively and clients wait until the first portion of the data is broadcast. Although the server can deliver the data to many clients concurrently, clients have to wait until their desired data are broadcast.

The H‐AHB method further reduces waiting time by scheduling an effective broadcast that considers the number of clients' available channels.

The purpose of this paper is to provide a tutorial and survey on recent advances in multimedia networking from an integrated perspective of both video networking and building digital video libraries. The nature of video networking, coupled with various recent developments in standards, proposals and applications, poses great challenges to the research and industrial communities working in this area.

This paper presents an insightful analysis for recent and emerging multimedia applications in digital video libraries and on video coding standards and their applications in digital libraries. Emphasis is given on those standards and mechanisms that enable multimedia content adaptation fully interoperable according to the vision of Universal Multimedia Access vision.

The tutorial helps elucidate the similarities and differences among the considered standards and networking applications. A number of research trends and challenges are identified, and selected promising solutions are discussed. This practice would needle further thoughts on the development of this area and open-up more research and application opportunities.

The paper does not provide methodical studies of networking application scenarios for all the discussed video coding standards and Quality of Service (QoS) management mechanisms.

The paper provides an overview of which technologies/mechanisms are being used broadly in networking scenarios of digital video libraries. The discussed networking scenarios bring together video coding standards and various emerging wireless networking paradigms toward innovative application scenarios.

QoS mechanisms and video coding standards that support multimedia applications for digital video libraries need to become well-known by library managers and professional associations in the fields of libraries and archives. The comprehensive overview and critiques on existing standards and application approaches offer a valuable reference for researchers and system developers in related research and industrial communities.

New application types such as distributed multimedia applications have to provide a certain quality of service (QoS) to the users. Since they handle time‐critical information such as audio and video data, they need appropriate support from the system components and especially from the network. New protocols and mechanisms have been developed over recent years to offer integrated services by serving both discrete media data (such as text and graphics) and continuous‐media data (i.e. audio and video) in digital networks. Internet and asynchronous transfer mode (ATM) are the main players in this area and both possess QoS architectures which allow them to integrate services of data‐ and tele‐ communications formerly performed by separate infrastructures. We believe that both will co‐exist for a significant amount of time, potentially complemented by other, perhaps simpler, approaches which are currently under investigation, such as differentiated services. Therefore, an interaction between these two architectures is necessary. In this paper, we discuss interaction approaches for the QoS architectures developed for the Internet and for ATM. We base this description on requirements and scenarios of multimedia applications and on the possible communication patterns considering different topological variants for heterogeneous Internet‐ATM networks.

This paper aims to provide an overview of representative multimedia applications in the cultural heritage sector, as well as research results on quality of service (QoS) mechanisms in internet protocol (IP) networks that support such applications.

The paper's approach is a literature review.

Cultural heritage multimedia applications require greater bandwidth capacity, especially where multiple users share the connections. For such applications, scalability and reliability of quality of service depend on packet‐level QoS mechanisms operating in a full end‐to‐end basis.

The paper provides a foundation for future research directions in the professional communication context. For instance, the QoS mechanisms in possible network infrastructures could be used to explore effective multimedia data dissemination across cultural heritage institutions.

The paper provides an overview of which technologies/mechanisms are being used most broadly and which might provide the most potential for cultural heritage institutions managers considering experimenting in the multimedia communications area.

QoS mechanisms that support multimedia applications in the cultural heritage sector need to become well known by cultural heritage institutions managers and professional associations in the fields of libraries, museums and archives. This paper provides a useful overview of the topic.

Big data generated on social media offers rich sources of information for the study of service quality. Although a still incipient field in hospitality and tourism studies, the growth of user-generated content sources has driven the development of big data analytics to discover significant patterns on customer experiences and satisfaction. The chapter explores how this analysis of texts from TripAdvisor provides insights on the service quality in Barcelona’s hospitality sector. Drawing on the results from this case study, the chapter argues that user-generated content can become an important tool in guiding better service delivery.

The purpose of this paper is to reduce the waiting time on webcast for selective contents, by proposing a scheduling method called the “contents prefetched broadcasting considering user participation” (CPB‐CP) method.

The authors analyze and evaluate the performance of the proposed CPB‐CP method.

It is confirmed that the proposed method gives shorter average waiting time than the conventional methods.

A future direction of this study will involve making a scheduling method in the case where the playing time of each content item is different.

In selective contents delivery, users may wait for the next bit of content to start playing after watching the previous one. In quiz programs, users may wait to receive the content data for their selected answer after they select their answer.

In the CPB‐CP method, when a provider node pulls out of the network while delivering contents, waiting time is reduced effectively by reconstructing a delivery schedule that considers the available bandwidth of each provider node.

This study examines some pertinent individual-level factors and consequences of consumers' continuous social media brand engagement (SMBE) practices. Further, this study examines the moderating effect of other-efficacy to deepen the understanding.

Online survey data collected from 785 respondents, through a convenience sampling technique on Facebook, was analyzed through structural equation (SEM) modeling with AMOS 23.0.

The findings suggest that compatibility with lifestyle, perceived information quality and escapism, which significantly drive consumers' continuous engagement with brands on social media. However, perceived enjoyment does not. Other-efficacy duly moderates consumers' continuous SMBE practices. While continuous SMBE significantly drives consumer-based brand equity (CBBE), continuous SMBE does not have any significant relationship with consumers' subjective well-being (SWB).

This study reports robust findings on the effects of individual-level factors that drive consumers' continuous SMBE practices. However, the study only focused on Facebook brand pages. This is a limitation for generalizability of results because the research did not take a holistic view of all types of social media.

The research suggests a need for managers to project their brands and share relevant and stimulating information throughout their continuous SMBE with consumers to build strong consumer–brand relationships. Managers should also engage consumers with interesting social media messages as well as both informative and transformative creative strategies to excite them. This will further give consumers a reason to continuously interact with the brand on social media platforms.

This study is one of the very few works to tease out pertinent factors that drive consumers' continuous SMBE practices. The paper integrates the consumer-level factors and moderating effects of other-efficacy through the lens of Social Cognitive Theory (SCT) and Uses and Gratification Theory (UGT) to make a significant contribution to the SMBE literature.
