  • In digital broadcasting, applications are computer programs executed by the set-top box(TV receiver) , and synchronized applications are those that perform tasks at the specified moments in the underlying video. This paper describes important concepts, standards, and skills needed to implement synchronized applications and explains how to integrate them to implement these applications. This Paper assumes the European data broadcasting standard, DVB-MHP. In DVB-MHP, scheduled stream events are recommended as a means of synchronizing applications with video streams. In this method, the application receives each stream event, and executes the action associated with the stream event at the time specified in the stream event. Commercially available stream generators, i.e., multiplexers, do not generate transport streams that support scheduled stream events. So we used a stream generator implemented in our lab. We implemented a synchronized application where the actions triggered by stream events are to display graphic images. We found that our synchronized application processes scheduled stream events successfully. In our experimentation, the stream events were synchronized with the video and the deviation from the intended time was within 240 ㎳, which is a tolerance for synchronization skew between graphic images and video.

  • At present, it is very common to use techniques beyond the 2D (two-dimensional) in animations which are found in motion pictures, OVA and TV series. As you can see, PIXAR and Disney have reduced their 2D departments and recently put more effort into 3D (three-dimensional) animation. There is no doubt that producing 3D animation is the big trend. Along with this trend, the national education institutions and the national support policies are also changing to be supportive of 3D animations. We, however, should ask ourselves, if we are on the right track with this change. Through the analysis of the methods of creating 2D animation which we should keep as it is, but instead we import and incorporate with 3D techniques of Japanese 2D animation, I would like to present the importance and the significance of the 2D animation and also to suggest an effective way to create 2D fused with 3D computer graphics techniques.

  • As the Internet appliances like digital TV, Internet set-top boxes, and Internet phone, are showing up in the market, the economics of real-time operating system (RTOS), which is an essential for controlling those devices, is expanding faster than ever before. ETRI has developed describes RTOS called Qplus-P, targeting various platforms ranging from PDA to Internet set-top box and home server. This paper describes the implementation of graphic window library for Qplus-P. The Qplus-P graphic window library was implemented using tiny-X graphic server and gtk graphic toolkit, which are open source software. To port this library to various aliances, hangul processing, screen rotation, touch screen, and graphic acceleration functions are added to the tiny-X graphic server of the implementd graphic window library. Currently, Qplus-P graphic window is running on ARM-based appliances such as iPaq PDA, Samsung S3C2400 board, Zaurus PDA, and on Home Server that uses x86 processor. Qplus-P graphic library is provided as a of Qplus-P target builder.

  • Existing method of creating Stereoscopy image, creates viewpoint image from the left and right by shooting one object with 2 lens in certain distance. However, in case of 3-D TV using Stereoscopy camera, the necessity to transmit 2 viewpoint images from the left and right simultaneously, increases the amount of bandwidth. Various and more effective alternatives are under discussion. Among the alternatives, DIBR(Depth Image Based Rendering) creates viewpoint images from the left and right using one image and its Depth information, thus decreasing the amount of transmitted bandwidth. For this reason, there have been various studies on Algorithm to create DIBR Image in existing Static Scene. In this paper, I would like to suggest Gaussian Hole-filling solution, which utilizes reverse-depth image to fill the hole naturally, while minimizing distortion of background. In addition, we have analyzed the effectiveness of each Algorithm by comparing and calculating its functions.

  • In this paper, Hwang Soon-won's "Sonagi" is considered from the aspect of literary imagination reconstructed into a fusion content of various cultures such as HD TV Literature, Animation, Movie, Musical, CF and the part which changed from the original text. In the TV literature Museum "Sonagi" he created a newly person called a 'Seok-yi' who is a young brother of a boy, a girl's mother who did not exist in the original, and developed the composition more precisely. And In the animation, the main character's dialogue is presented as a speech and it is characteristic that the theme of the work is revealed more effectively. On the other hand, the heroine in the movie says, "I do not like the ending part of the showers." Also In the musical "Sonagi", about 2 tons of water was used to give more vividness and presence to the audience. In this way, the contents of the original works are transformed according to the characteristics of the medium in the various cultural fusion contents based on novels, and thus convey the unique imagination of the director to the audience.

  • For us who live in the 21 century, a variety of media and videos such as TV, movies, magazines, internet, etc. have now become indispensable entities. Because of changing age, unlimited sharing of information, and development of machines, fashion and ideas are rapidly conveyed and theres is also a tendency to seek after more sense based and stimulating things. Around us, there are innumerable colors which do not seem to have any special presence like the air and go beyond human ability to identify them. Such colors exert direct influence upon the visual culture and most rapidly reflect that age's trend. It is precisely from this perspective that the importance of neon colors, which have recently received the spotlight, have emerged in a magnified way. Yet, although much research has been conducted on colors by earlier studies, there has been no research on neon colors and as such, I felt the need for a study of neon colors. The purpose of this study is to recognize the importance and psychology of colors within the visual culture, discover whether there is a correlation between the characteristics of neon colors and the visual culture, and seek ways to demonstrate it by applying it to art education.

  • Former times Information Technology generally has only depended on text or sound, while nowadays information is being moved through a variety of image media. Cell phone, TV and computer have been major elements of modem society as mediators using image signal. Therefore, image signal processing also has been treated importantly and done actively. The processing has been developed in many fields of digital image processing technologies as image data compression, recognition, restoration, etc. Noises are inevitably generated by using the signals during the processing, and typical types of the noise are Impulse(salt & pepper) and AWGN(Addiction White Gaussian Noise). To reduce the noise, various kinds of filters have been developed, and according to each noise, it is being used different filter each. However, the noise is not generated by one signal but by a complex. In this paper, I suggested an image filter to remove the complex noise, and compared with existing filters' methods for verification.
