Lately, development of multimedia industry has multimedia data serviced through various wire wireless communicating environment. These multimedia data is displayed on the device of various sizes such as mobile telephone, PDA, notebook, PC. Therefore, there has needed to resize multimedia data appropriate to the screen size of user's display device. In this paper, we propose the method to resizing H.264 videos sequence fitting to the screen size of user's display device. The existing most methods reduce the size of video sequence, but this paper proposes the upsampling method. The results show the proposed method upsamples video sequences without blocking effects.

In this paper, teaching object-oriented design in a programming course is a big challenge for instructors. "Objects-first" is a popular strategy for teaching object-oriented programming in the educational settings, by introducing the concepts of objects, classes, and instances before procedural elements of a programming language. Still, this approach emphasizes coding rather than other critical aspects of software development, notably problem-solving and design. We propose a "design-first" approach, which subsumes an objects-first approach into lessons that also introduce object-oriented analysis and design, using elements of UML before implementing any code. We also present video rental store (SRS) that uses the design-first approach to help students of various teaming styles in a software engineering course. It interfaces with an IDE we have chosen specifically to support the design-first approach, and SRS which has been shown to be effective in helping students learn object-oriented programming concepts.

According to development of computer technology, the utilization of the fourth generation of digital photogrammetry progresses favorable. Especially the method of using digital video camera is very practicable and has an advantage such as a profitability for the amateur. In road field which if centrical facilities of national industry, this method was utilized to acquire road information for the safety diagnosis or maintenance. In this study, 3-dimensional position information of road centerline was extracted using digital video camera which has practicality and economical efficiency. This data could be a basic source in road information project.

Nowadays, as the quantity of multimedia information increases rapidly, an efficient management for multimedia has become more important. In this paper, to index and search multimedia contents efficiently, we designed the algorithm searching specific image and saving the extracted image using the semantic information extraction scheme based on contents and it is one of the schemes to indexing and searching of video data. After extracting the RGB information from input image, while all frames of video is inspected sequentially, the specific image is saved through referring to the position and distribution of contents from the collection scheme of RGB range. In case of using the proposed image extraction algorithm, because only saved video is searched instead of the whole the searching time can be reduced.

In the TV broadcasting, movie production and business the transportation of video between creators (programmers, studios) and distributors (broadcast and cable networks, cable and satellites companies) is still a mix of File Transfer Protocol (FTP), physical delivery, and expensive multicast satellite. Cloud-based file sync-and-share providers like Dropbox and box are playing an increasing role, but the industry's unique demands for speed and multicasting have fueled the growth of IP Video transport. This paper gives a solid grasp of the major elements of IP video technology, including content preparation, system architecture alternatives and network performance management.

In this paper, We propose an efficient automatic caption detection and location method, caption recognition using FE-MCBP(Feature Extraction based Multichained BackPropagation) neural network for content based retrieval of video. Frames are selected at fixed time interval from video and key frames are selected by gray scale histogram method. for each key frames, segmentation is performed and caption lines are detected using line scan method. lastly each characters are separated. This research improves speed and efficiency by color segmentation using local maximum analysis method before line scanning. Caption detection is a first stage of multimedia database organization and detected captions are used as input of text recognition system. Recognized captions can be searched by content based retrieval method.

The Current 7th Curriculum for Computer Education emphasized the class of practice oriented, student oriented. But it is very hard because of many students, poor environments, insufficiency of the teaching model. So ADPM will gives our help. a ADPM based practical class using ebook synchronized with video files give a little student's wating time for answering, much student's learning efficiency, much student's voluntary learning custom, a individualized learning. And this study developed the prototype to support the ADPM. This prototype will make up for the weak points in authoring systems, which they are a wizard type program, capturing video file, synchronizing video files. And it will improve a practical class.

According as computer industry develops and the Internet is spread information interchange between remote users video conference system that can exchange multimedia data such as voice as well as simplicity text data or burn by real-time appeared and is used in various field. However, most systems developed present have controversial points of that need expensive multi-point connection equipment or network resource of High band width. Hereupon, in this paper, designed and embody video conference system that can be stable and supplies multimedia information and screen public ownership environment of high-quality as software using minimum network resource without using expensive connection equipment.

The objective of digital broadcasting has evolved from providing a plain video service to offering a realistic visual experience. Technologies such as 3DTV and UHDTV have been suggested to achieve this new objective by providing an immersive and stereoscopic visual experience. However, owing to the high bandwidth requirements of such services, the broadcasting industry has faced a challenge to find a new transport mechanism for overcoming the bandwidth limitation. The standardization organizations, the Advanced Television Systems Committee, Digital Video Broadcasting, and Telecommunications Technology Association, have been working on the integration of broadcasting and a broadband network (IP) to resolve the bandwidth issue of realistic video services. This paper introduces a frame-level timeline synchronization and transport system target decoder model for providing a stable 3DTV service over a hybrid network. The experimental results indicate that the proposed technologies can be successfully adopted as a reference model in a broadcast-broadband hybrid 3DTV service and other IP-associated hybrid broadcasting services.

This study focused on popular YouTube subculture content and male YouTuber characteristics. We conducted a case study on YouTube videos and viewer's comments of male YouTubers who interacted with subculture or fashion themes within YouTube. Based on Dick Hebdige's subculture theory, we categorized male subculture characteristics of style expression to show how YouTube plays a role in the formation of subculture. The representative types of male subculture were divided into metro sexual, adolescent boys, drag queen, and homosexual. YouTube simultaneously played a role in accumulating video viewing as well as indirect experiences in various communication activities and cultures among viewers. YouTube was used as a space for video producers as well as viewers and subscribers to discover and build identity. Subculture makes people aware of cultural diversity within society, and their doubles and lifestyles serve as important clues to track culture and fashion changes. This research is significant in the field of fashion media and subculture research due to its examination of male subculture phenomenon on YouTube based on an analysis of the video content of culture insiders and viewers' comments as well as immediate responses.
