Cloud computing is becoming one of the most convenient ways for information services through network accesses. In this paper, we describe the architecture of cloud computing and discuss the issue of in-cast, which may downgrade the transmission performance when the number of simultaneous transmission servers is getting larger. The in-cast transmission may introduce the out of sequence of packet delivery and may reduce the system throughput. This paper constructs the software environment to simulate the performance of video streaming services delivered by the servers in cloud. We first examine the performance of the out of sequence issue of packet transmission when the Hashed Credit Fair (HCF) algorithm was applied and investigate the multicast performance of video streaming service with respect to the numbers of servers. With the increasing of the number of servers, we note that transmission performance is not improved, on the contrary, the system throughput downgrades sharply. We believe the simulation results of this paper will be helpful for the design of cloud video multicast services.

For several years, cloud computing systems have been generating debate and interest within IT corporations. These cloud computing environments provide storage and processing systems that are adaptable, efficient and simple, thus allowing for rapid infrastructure modifications to be made, according to constantly changing workloads. Organizations of any size and type are migrating to the cloud supporting solutions based on Web. Due to the benefits of the pay-per-use model and scalability factors, services such as Video Streaming. Recent failure events in Video Streaming services have demonstrated the critical importance of maintaining high availability in cloud computing infrastructures. One of the methods used to identify the trends of occurrences of failures in computational systems, occurs through the application of strategies of sensitivity analysis. This paper uses hierarchical modeling and different sensitivity analysis techniques to determine the parameters that cause the greatest impact on the availability of a Video on Demand.  The results show that distinct approaches provide similar results regarding the sensitivity ranking, with specific exceptions. A combined evaluation indicates that system availability may be improved effectively by focusing on a reduced set of factors that produce large variation on the measure of interest.

Current TV and video viewing patterns have changed. Viewers were not completely fixated by broadcast hours and broadcast times. In the internet era, people can watch TV anytime and anywhere. Besides, we do not necessarily watch TV shows from the TV set but our smartphone or laptop gadget. Video streaming services are now increasingly popular in various circles because it can be accessed quickly, anytime, and anywhere. As a significant media business in Indonesia, MNC Group is widening its market presence by launching RCTI+ to gain a large share in digital advertising. To complement its already strong FTA position, RCTI+, a multi-application, including the streaming TV and Video on Demand service, is expected to be Indonesia's most extensive streaming service. How marketing communication in the digitization process since MNC Media must reach a new audience is the digital audience. This article will examine how MNC Media conducts communication marketing in the digitization process in its television business by building RCTI+ to reach its new audiences or digital audiences. This paper used the Descriptive Qualitative method, and this research collects data by interviewing the Chief Operating Officer and Dept. Head of Promotion RCTI+, conducting literature and document studies. Based on the research results, RCTI+ integrates its promotional pillars acquisition and retention, running simultaneously to harmonize its marketing communication.  RCTI+ strives to build a brand and profitable relationships with customers through these two pillars to create brand equity.

Over Time

Purpose This study aims to investigate the evolution of factors that influence the current and future use of video streaming applications by Millennial consumers. Design/methodology/approach Combining technology acceptance, perceived values and user identity theory this study used factor analysis and multiple regression to examine data from a survey of 292 university undergraduates. Findings Millennial’s current and future use of video streaming services remains driven more by social and emotional values and their effect on identity salience with their choice of content. Ease of use, convenience and monetary value remains less of an influence currently but may become more important in the future with the continued maturity of the industry. Practical implications The results of this study suggest that video streaming service providers should be developing business models that recognize the increasing importance of emotional appeal and self-identity of their service offerings as the industry matures and competition increases. Originality/value The research is novel in addressing future video streaming service provision by examining changes in young consumer behaviour over time within a similar sample population and considering the growth and technological advancement of video streaming services. The results are significant in addressing the gap that exists in understanding whether perceived values for technology adoption of the same product or service by millennials change over time and the implications that have for product and service providers.

The Relationship

A mobile ad hoc network (MANET) is a set of autonomous mobile devices connected by wireless links in a distributed manner and without a fixed infrastructure. Real-time multimedia services, such as video-streaming over MANETs, offers very promising applications, e.g., two members of a group of tourists who want to share a video transmitted through the MANET they form, a video-streaming service deployed over a MANET where users watch a film, among other examples. On the other hand, social web technologies, where people actively interact online with others through social networks, are leading to a socialization of networks. Information of interaction among users is being used to provide socially-enhanced software. To achieve this, we need to know the strength of the relationship between a given user and each user they interact with. This strength of the relationship can be measured through a concept called tie strength (TS), first introduced by Mark Granovetter in 1973. In this article, we modify our previous proposal named multipath multimedia dynamic source routing (MMDSR) protocol to include a social metric TS in the decisions taken by the forwarding algorithm. We find a trade-off between the quality of service (QoS) and the trust level between users who form the forwarding path in the MANET. Our goal is to increase the trust metric while the QoS is not affected significantly.
