Recently, many kinds of TV contents based on multimedia need transmission systems without the saved. In this study, we develop the streaming device and smart app to transmit and play without store for multimedia contents such a broadcasting, internet, VOD, video, and animation. To do this, we compare and analysis main CPU products, broadcasting tuners and interfaces for streaming sources, and memory products. We then design and implement the streaming device which supports 30fps@FHD H.264 decoding and streaming, and multimedia sources with more than three. We develop the software for these requirements. Thissystemis useful to support billing service for multimedia contents.

Recently, gamification has garnered high attention in various fields outside the traditional game world through the adoption of game techniques. The introduction of gamification creates an alternate reality game. It appears virtually the same as other normal games, but is able to pull down the boundary between reality and imagination. At first, this was utilized by the entertainment industry for movies, advertisements, and drama publicity. We can see examples of gamification extending into the knowledge and information contents field. The purpose of knowledge and information contents is to pursue meaning and utility rather than fun, though the introduction of game methods remains interesting. In-depth examination of the conception of an alternate reality game via gamification will lead to the understanding of progression and quality of alternate reality games in the context of knowledge and information contents. As a result, we can effectively understand not only the immediate uses but also be able to measure the potential for utilization of gamification for various fields.

Nowadays we are not able to consider and imagine anything without taking into account what is called Artificial Intelligence. Even broadcasting media technologies could not be thought of outside this newly emerging technology of A.I.. Since the last part of 20th century, this technology seemingly is accelerating it's development thanks to an unbelievably enormous computational capacity of data information treatments. In conjunction with the firmly established worldwide platform companies like GAFA(Google, Amazon, Facebook, Apple), the key cutting edge technologies dubbed NBIC(Nanotech, Biotech, Information Technology, Cognitive science) converge to change the map of the current civilization by affecting the human relationship with the world and hence modifying what is essential in humans. Under the sign of the converging technologies, the relatively recently coined concepts such as 'trans(post)humanism' are emerging in the academic sphere in the North American and Major European regions. Even though the so-called trans(post)human movements are prevailing in the major technological spots, we have to say that these terms do not yet reach an unanimous acceptation among many experts coming from diverse fields. Indeed trans(post)humanism as a sort of obscure term has been a largely controversial trend. Because there have been many different opinions depending on scientific, philosophical, medical, engineering scholars like Peter Sloterdijk, K. N. Hayles, Neil Badington, Raymond Kurzweil, Hans Moravec, Laurent Alexandre, Gilbert Hottois just to name a few. However, considering the highly dazzling development of artificial intelligence technology basically functioning in conjunction with the cybernetic communication system firstly conceived by Nobert Wiener, MIT mathematician, we can not avoid questioning what A. I. signifies and how it will affect the current media communication environment.

Currently, H.264/AVC is used in many multimedia applications. Also, The MPEG-2 main profile which supports B pictures for bi-directional motion prediction is widely used in applications such as HDTV and DVD’s. Therefore, transcoding the MPEG-2 main profile to the H.264/AVC baseline is necessary for universal multimedia access. In this transcoding architecture including the GOP structure conversion, the proposed algorithms adopt the adaptive search range selection through the linearity test of a predictive motion vector and adaptive mode selection using the reference region complexity information. The proposed algorithms extremely reduce the computational complexity while maintaining the video quality.

As success stories of using virtual reality (VR) have become more prevalent, interest in performance-related technology has rapidly increased around the world. Performances such as, Cirque du Soleil had much success in using video technology, these VR applications have enabled experiences using digital image technology. However, critics have claimed that the completeness and diversity of visual content is reduced, due to insufficient storylines, spatial composition, and partial use of the entire visual field. Therefore, the design of a performance using digital image technology should consider the characteristics of the production stage to be different from real world performances. In this study, the visual space of the stage, the method of creating space for the stage, and the movement of the performer and utilization of the performance was analyzed. Through this, It transferred the limitation of the traditional stage into the space and time of the image and opened the possibilities of the tran­-media.

Short-form content, which means "short video content within 10 minutes," is rapidly emerging as a recent trend among MZ generations based on the fact that it can be viewed whenever there is a short running time, and they are physically short, colorful, and deliver a lot of information in a compressed time, showing differences in both long-form content and format. In addition, entertainment videos such as information delivery videos, eating shows, web entertainment, and dance challenges are mainly produced and distributed, so there is no need to take expertise as a creative work of video experts, and consumers often become producers by directly participating in production using low-end equipment such as smartphones. For these reasons, shortform content creates new image styles rather than general existing image forms such as long-form contents, and this study focuses on changes in editing styles. This study summarized the following five characteristic changes by analyzing the editing style of short form content that has changed compared to long form content according to the 'visual' aspect. The use of frames, memes, screen division, blue screen, and subtitles are included, and by organizing each characteristic, we identified the editing style of shortform content that has emerged as a recent trend and learned about the changes.

Digital signage takes the role of promotion, providing information, art and game as it is installed in various forms everywhere such as the road, subway and indoor space we pass through. The related researches also focus on the technology of realizing digital signage, current industrial state and prospect in most cases. On the contrary, the researches on the spaciality of digital signage is a kind of insufficient, this study was carried out based on the judgment that there is necessity of researching it in respect that the recognition of space by the people in there is different before and after digital signage is located in such space. First, in order to understand digital signage, its concept, type and kind were investigated, general theories about the spaciality were considered after that, the spaciality of digital signage was grasped by 5 factors such as hybridity, vitality, mobility, flexibility, and contingency and their characteristics were offered in this study. In its conclusion, it was appealed that the change of spatial recognition along media and continuous research are required as digital signage is the transactive space.

The theme of this research is the music visualization on stage. As the collaborated work, combining the dance, images with the Isang Yun's music, is showing the staged music, which is expressing the music not only through the sound but also the visualization. In the process of visualizing the music through the body and images on the stage, Isang Yun's musics are recreated in the hand of today's artists. The study found that the recreated work from the new point of view, like Interview with Isang Yun can be the bridge between the composer and today's artists and we can see the future through it. Even though, this paper analyzed the work through the aspects of dance and images, the main theme of the work is focusing how can we deliver the music in the new representative form through formative visualization on the stage.
