As the performance of the next-generation broadband wireless networks is dramatically enhanced, various services (i.e., education, Live video streaming, Live video conferencing, online games, etc.) have been provided to users through a smart mobile platform. Those services are usually provided by using the centralized communication server. However, since all multimedia traffic is exchanged through a communication server, it often has the scalability problem with regard to traffic management. Our main purpose is for group smart users to provide scalable live multimedia streaming service based on P2P network. To do this, we have designed an architecture of P2P-based service management for mobile group communication management and service management protocol. In order to verify the performance of the proposed scheme, we have mathematically analyzed the performance in terms of the average transmission delay and bandwid th utilization.

Concomitant with development of AR(Augmented Reality) and VR(Virtual Reality), interest in location based games and augmented reality have increased and various services have been developed. Due to this, AR, VR, MR(Merged Reality) techniques are considered one of fourth industrial revolution techniques. Oculus Rift which is representative of VR technology, and HTC VIVE need separate controllers, and don't offer service such as receiving external video information when users are using devices. In the case of project Alloy, which is a MR device of Intel, this has advantages such as controlling devices through hand signals and facial expressions, and receiving external video information. In this paper, we propose tourist guide system based on current position using MR. This system makes economical tour possible by arranging tourist attraction information which is from current position of tourists in correct places through external video information using MR, location determination using GPS, tourism information search using wireless internet.

This paper suggests a different reading of James Joyce's "Araby" by offering the video game as a lens through which we can reimagine the story. Understanding the unnamed boy's journey to the Araby bazaar as a fetch quest, this paper focuses on the boy's failure to complete this quest. As soon as the boy promises Mangan's sister something from Araby, his fetch quest begins. In order to complete the quest, the boy must successfully perform three sub-quests: get money from his uncle as early as he can, get on the train for the Araby bazaar on time, and pass through the sixpenny entrance at the bazaar. However, because his uncle comes home late, the boy fails to get the money early, and that sets off the subsequent failures. The boy then takes the train late and arrives at the bazaar so late that he feels he must go through any entrance. So he walks through the adult entrance by mistake. As a result, he does not have enough money to buy a gift, failing the larger quest. But, regardless of this failure, the boy can try these quests as many as he wants until he finally succeeds in completing them. But no matter how the boy tries to accomplish these subquests, he is doomed to fail them because he cannot make his uncle come home early. The more he tries his quest, the more bitterly he realizes that he will ultimately fail. In this respect, the boy's "anguish and anger" should be understood as his epiphany: the re-playability of the game is possible, but all the replays lead to the same failure: losing the game. In this regard, reading Joyce's "Araby" is much like playing a video game.

YouTube, the most representative video sharing platform, is used by millions every day. New videos across various fields, such as daily life, beauty, games, eating, fashion, and music are constantly being uploaded. Among the content available on YouTube, beauty-related videos are particularly popular. Creators who produce and share beauty-related content on online media platforms are known as beauty creators. There is a significant amount of beauty-related content produced in response to high public interest. Most of this content focuses on sponsored advertisements related to product relevance and attitudes, such as makeup tutorials, hairstyle creation, and new product reviews. However, there is a lack of research on the diverse environments of self-media beauty creators and basic makeup production techniques. This study investigated the content composition of individual media YouTube beauty creators and examined the current status of YouTube beauty creators in Korea. This research is necessary for the development of diverse content and videos by beauty creators. Based on these findings, a makeup technique was developed for YouTube beauty creators, considering the production environment of marketing content and video production steps. This study aims to expand and specialize the broad range of content environments of beauty creators and develop makeup techniques that can be effectively used in YouTube content production.

The recent progress in multimedia signal processing and transmission technologies has contributed to the extensive use of multimedia devices to watch sports games with small LCD panel. However, the most of video sequences are captured for normal viewing on standard TV or HDTV, for cost reasons, merely resized and delivered without additional editing. This may give the small-display-viewers uncomfortable experiences in understanding what is happening in a scene. For instance, in a soccer video sequence taken by a long-shot camera techniques, the tiny objects (e.g., soccer ball and players) may not be clearly viewed on the small LCD panel. Moreover, it is also difficult to recognize the contents of the scorebox which contains the elapsed time and scores. This renuires intelligent display technique to provide small-display-viewers with better experience. To this end, one of the key technologies is to determine region of interest (ROI) and display the magnified ROI on the screen, where ROI is a part of the scene that viewers pay more attention to than other regions. Examples include a region surrounding a ball in long-shot and a scorebox located in the comer of each frame. In this paper, we propose a scheme for raising viewing experiences of multimedia mobile device users. Instead of taking generic approaches utilizing visually salient features for extraction of ROI in a scene, we take domain-specific approach to exploit unique attributes of the soccer video. The proposed scheme consists of two modules: ROI determination and scorebox extraction. The experimental results show that the proposed scheme offers useful tools for intelligent video display on multimedia mobile devices.

The arcade gun has been a popular game controller in the video game market from the 1970s. The arcade gun, which is used partially in game centers and domestic games, recently is utilized as the interface for the interactive system and tangible media. On the other hand, the existing arcade gun has limits on hardware so it is unsuitable for wide screens. In addition, being platform-dependent, it is inapplicable to various types of content as a single module. This study suggests a correction algorithm that establishes an arcade gun system based on an infrared camera to solve those drawbacks and apply to possibly numerous surroundings.

Multicast protocols are efficient methods of group communication such as video conference, Internet broadcasting and On-Line Game, but they do not support the various transmission protocol services like a reliability guarantee, FTP, or Telnet that TCPs do. The Purpose or this Paper is to find a method to utilize multicast routers can simultaneously transport multicast packets and TCP packets. For multicast network scalability and error recovery the existing SRM(Scalable Reliable Multicast)method has been used. Three packets per TCP transmission control window site are used for transport and an ACK is used for flow control. A CBR(Constant Bit Rate) and a SRM is used for UDP traffic control. Divided on whether a UDP multicast packet and TCP unicast packet is used simultaneously or only a UDP multicast packet transport is used, the multicast receiver with the longest delay is measured on the number of packets and its data receiving rate. It can be seen that the UDP packet and the TCP's IP packet can be simultaneously used in a server router.
