In film various techniques interact organically in order to bring a story to life and, by doing so, influence the audience's perception. The techniques composing the form of a film are part of a format-system and therefore have to be well adjusted to the content of the film to trigger an intended effect. It is then that these techniques boost the intensity of the audience's emotional experience. The subject of analysis in this study of aesthetic composition, which is part of the concept of visual narrative, is the movie "Silence", which depicts a disturbing story based on real events. The goal of this study is the analysis of composition techniques used to support the film's narrative structure, where elaborate frame-composition and techniques are applied with great efficiency. Another goal is also to illustrate the meaning of film-format and its importance. Looking deeper into the question of how meaning and emotions, which are inherent in a film, finally manifest themselves on screen through a single shot, where the cinematographer's ideas and aesthetic vision come together and also the question of how a narrative structure in the context of a film works- these questions are the essence of this study.

Public debate is an essential communication process of our society and now it's carried out generally by television. The purpose of this study is to discuss on the potentialities and limits of TV debate as a public space. First, we examine the way of television's construction of public debate to discover the conventions of the genre. Second, examine its limitation and potentials as an public sphere. We analyse four TV debate programs during one month(June, 2001) using text analysis: format construction, nature of agenda, characteristics of panels and chairman, participation of audience, type of knowledge. The result shows that although numbers of programs are increased, many TV debates not differentiated each other in their format, panel, and contents, and merely reproduce genre conventions. Especially in policy debates, abstract agenda, male-dominated panel, limited participation of audience, and elitism and authoritative are prevailing. The genre's preconceived formulae and fixed convention restrict its own possibility of a participant and democratic public sphere. So, in order for TV debates to function as a open public sphere, to be flexible and re-examinate the proper frame for mass media public sphere.

This study examined how newspapers covered the 60th anniversary of the historical event, 8 15 Independence Day. Specifically, five newspapers from three countries were content-analyzed to see differences, if any, based on country level and political ideology of the newspaper. The findings showed that Japanese newspapers yielded less amount of coverage than those of Korea and China. The newspapers of Korea and China used straight news format, while Japanese newspapers used opinion news format. In terms of information source, Korean newspapers and Chinese newspapers mainly relied on the information from the government, while Japanese newspapers took the information from citizen. The difference also revealed that Korean newspapers focused on domestic situation frame and the other countries more emphasized past memory of the War times. Consequently, the three countries showed clearly different perspectives on the same historical event. These distinctions were caused from national interest rather than political ideology of the newspaper.

With the recent development of hardware computing devices and software based frameworks, machine tasks using deep learning networks are expected to be utilized in various industrial fields and personal IoT devices. However, in order to overcome the limitations of high cost device for utilizing the deep learning network and that the user may not receive the results requested when only the machine task results are transmitted from the server, Collaborative Intelligence (CI) proposed the transmission of feature maps as a solution. In this paper, an efficient compression method for feature maps with vast data sizes to support the CI paradigm was analyzed and presented through experiments. This method increases redundancy by applying feature map reordering to improve compression efficiency in traditional video codecs, and proposes a feature map method that improves compression efficiency and maintains the performance of machine tasks by simultaneously utilizing image compression format and video compression format. As a result of the experiment, the proposed method shows 14.29% gain in BD-rate of BPP and mAP compared to the feature compression anchor of MPEG-VCM.

In this study, it was witnessed that a variety of tests are implemented in a type of convergence of multimedia such as photos, sounds, and videos as well as letters and drawings, components of existing traditional comics as comics are digitalized and are converted to various devices. Therefore, we studied the concept of multimedia comics as a basis of this study by judging that new barometer to comics lies in convergence with such multimedia. After recognizing components of multimedia comics which are currently emerging, we categorized them into three types depending on how to use these elements. First, convergence type webtoon has a very similar format with existing vertical scrolling webtoon and has characteristics that background & effects sounds are added to emphasize the features of webtoon, or photos or videos are inserted in part, and there is no function to control these elements; Second, motion comic, a medium format between comic and animation has a characteristic that sound, video, paging are auto-played like watching animation but it keeps the format of comics within one frame; Third, interactive comic has a characteristic that effects sound, motion, and story are made by active participation of viewers. As a result of analyzing comics which having above multimedia characteristics, its implications are as followings: First, multimedia elements should be used depending on genre, age, and media; Second, high level of control technology considering the features of comic-viewers is needed. In other words, in continuously evolving media environments, comic contents being proper to targets and use purposes of viewers should be developed. For this, multimedia elements of comics should be used in order that comic-viewers can have active & interactive communication with contents.

The advancement of information technology along with the proliferation of communication and multimedia has increased the demand of digital contents. Video data of digital contents such as VOD, NOD, Digital Library, IPTV, and UCC are getting more permeated in various application fields. Video data have sequential characteristic besides providing the spatial and temporal information in its 3D format, making searching or browsing ineffective due to long turnaround time. In this paper, we suggest ATVC(Authoring Tool for Video Contents) for solving this issue. ATVC is a video editing tool that detects key frames using visual rhythm and insert metadata such as keywords into key frames via XML tagging. Visual rhythm is applied to map 3D spatial and temporal information to 2D information. Its processing speed is fast because it can get pixel information without IDCT, and it can classify edit-effects such as cut, wipe, and dissolve. Since XML data save key frame information via XML tag and keyword information, it can furnish efficient browsing.

This paper proposed a novel H.264 deblocking filter for low-power mobile multimedia SoCs. In H.264 deblocking filter, filtering can be skipped on some pixels when pixel value differences satisfy some specific conditions. Furthermore, whole filtering can be skipped when quantization parameter is less than 16. Based on these features, power consumption can be significantly reduced by shutting down deblocking filter partially or as a whole. The proposed deblocking filter can shut down partial or whole blocks with simple control circuits. Common hardware performs both horizontal filtering and vertical filtering. It was implemented in silicon chip using $0.35{\mu}m$ standard cell library technology. The gate count is about 20,000 gates. The maximum operation frequency is 108MHz. The maximum throughput is 30 frame/s with CCIR601 image format.

Wireless link has high bit error rate compared with wired link and many users share this limited bandwidth. So it needs more powerful error control code and efficient media access control(MAC) to provide multimedia service reliably. In this paper we proposed efficient MAC frame format based on TDMA using mini-slot for request access. The number of mini-slots is variable based on the result of collision in the previous frame. This dynamic allocation of request mini-slots helps resolve the contention situation quickly and avoids the waste of bandwidth that may occur when there are several unneeded request mini-slots. The simulation results are also presented in terms of channel utilization, call blocking probability and cell transmission delay for mixed traffic environment.
