With a history of over 100 years, animation is an art of film and television, and a diversified special form of art as well. Animation scene design is not just about scenic painting but also a time-space formative art that serves for film and television animation, presents story plots, unveils dramatic conflicts and depicts character personalities. Scene design requires both high creativity and artistry. Scene design shall cover the living places, social environment, natural environment and historical environment where the characters live. The use of color is an important part in animation creation. In terms of scene design, it plays a significant role in building up the scene atmosphere, promote the plot and enriching screen contents. Focused on Uproar in Heaven-a classic Chinese animation, this paper analyzes the traditional characteristics of Chinese animation scene color and discusses the application and development of color.

We propose a method using a transformation of an object and a scene tree in order to author MPEG-4 contents for mobile devices in this paper. The method transforms media objects in the scene into geometry objects in order to reduce initial loading time of the contents, and reduces an external form of each object in a scene of the content for presenting it efficiently on the small interface of mobile devices. Therefore, the contents for mobile devices are reconstructed by the method. An original object in the scene is presented on a mobile device when a user clicks a related geometry object. The method was applied to a conventional authoring tool, so we could find that the method showed an efficient presentation of MPEG-4 contents on mobile devices.

Empathy is the ability to feel, understand, and respond to the emotions of others from the standpoint of others. Recently, 'sympathy' has emerged as an important issue not only in emotional empathy in relation to individuals but also in 'social empathy', which sees sympathy as a basic principle for maintaining society. This study focuses on the issue of empathy as a new driving force for modern society and focused on 'urban scene' as a spatial application for cultural empathy in the city. Urban scenes approach the city as a space of consumption, classify it according to its inherent attributes, and analyze its characteristics. This study approaches the existing urban scene theory in terms of empathy. In addition, as a way to consume city images reflected on contents, a concrete example of 'contents tourism'is examined, and a 'contents scene' is proposed as a new urban scene and its meaning and possibility are presented.

MPEG-4 content is streaming media that are composed of different types of media objects, organized in a hierarchical fashion. This paper proposes scene composition model for authoring MPEG-4 contents which can support object based interactions. And we have developed MPEG-4 contents authoring tool applied the proposed scene composition model as intermediate data structure. Particularly, for supporting interoperability between multimedia contents, the scene composition model should be used independent of file format. So visual scene composed of media objects on the from of scene composition tree can be transformed variable data format including BIFS, scene description from proposed by MPEG-4 standard and also support the extension of capability.

With the increase of mass contents data, a method of a scene change detection is required for analysis, indexing and editing. Although many researchers are studying a variety of scene change detection method, it is too difficult to accurately detect various movements of the cameras and scene changes. Also, earlier scene change detection methods take too much time to apply to UHD video contents. That is because the UHD video contents with 4K (3820x2160) resolution or higher have greater amount of data. Therefore a method for detecting a scene change by using the next-generation codec, HEVC, is required. In this paper, we propose four scene change detection methods using the coding additional information of HEVC, and a new pixel-based scene change detection system. Furthermore, through the experimental results, we check the possibility of detecting the scene changes of UHD videos encoded in HEVC format.

The Digital Multimedia Broadcasting(DMB) system is developed to offer high quality audio-visual multimedia contents to the mobile environment. The system adopts MPEG-4 standard for the main video, audio and other media format. It also adopts the MPEG-4 scene description for interactive multimedia contents. The animated and interactive contents can be actualized by BIFS(Binary Format for Scene), the binary format for scene description that refers to the spatio-temporal specifications and behaviors of the individual objects. As more interactive contents are, the scene description is also needed more high bitrate. However, the bandwidth for allocating meta data such as scene description is restrictive in mobile environment. On one hand, the DMB terminal starts demultiplexing content and decodes individual media by its own decoder. After decoding each media, rendering module presents each media stream according to the scene description. Thus the BIFS stream corresponding to the scene description should be decoded and parsed in advance of presenting media data. With these reason, the transmission delay of BIFS stream causes the delay of whole audio-visual scene presentation although the audio or video streams are encoded in very low bitrate. This paper presents the effective optimization technique for adapting BIFS stream into expected MPEG-2 TS bitrate without any bandwidth waste and avoiding the transmission delay of the initial scene description for interactive DMB contents.

Performance of a video browser greatly depends on the performance of scene change detection for the efficient retrieval and storage of the video contents which are major data in a current contents management system. In this paper we propose a new scene change detection method using Mean Difference Histogram of each frame section which improves accuracy of scene change detection as well as reduces the frequency of miss detection and fault detection of gradual scene change which is one of critical problem of the conventional histogram-based techniques.

Interactive DMB contents are provided by MPEG-4 scene description. The abundant interactions of the user bring on the high bit rate of MPEG-4 scene description. But DMB system has low bandwidth and limited bit rate. So we need new authoring method for MPEG-4 scene description. In this paper, we proposed a seamless authoring method for the DMB environment. It can generate BIFS information tinily and dynamically. The research result can be used by DMB system for a seamless MPEG-4 contents transmission.
