Recently, ITU-T/VCEG and ISO/IEC MPEG have started a new joint standardization activity on video coding, called High Efficiency Video Coding (HEVC). This new standard gives significant improvement in terms of picture quality for high resolution video. The main challenge in this upcoming standard is the time complexity. In this paper we have focused on CU splitting algorithm. We have proposed a novel algorithm which can terminate the CU splitting process early based on the RD cost of the parent and current level and the motion vector value of the current CU. Experimental result shows that our proposed algorithm gives on average more than about 10% decrement in time over ECU [8] with on average 1.78% of BD loss on the original.

In this paper, we propose a 360 content pilot service platform of cultural assets based on MPEG-V standard realistic media testbed. MPEG-V is that the standard format of sensory effect metadata(SEM) such like wind, light and flash, and communication protocol between sensory effect machines are defined, and it is possible to increase the sense of presence and immersion with 360 VR content. The proposed platform consists of software which is composed of the content player and the sensory effect reappearance server, and hardware which is the sensory effect machines. Also, the pilot service case using the proposed platform, and the features and advantages of the proposed platform are described.

This study aims to focus on realistic content of mixed-reality media, which has emerged as a new alternative due to COVID-19, we need to to investigate relevant cases in order to present the direction and prospect of development in preparation for the post-COVID19 era. Mixed-reality is a kind of media that expands physical abilities and it is widely used as a realistic type of content for education, training, performance, creation, game, and communication with acquaintances. Mixed-reality media will naturally permeate our daily lives like TV and the Internet in the post-COVID19 era. In the future, it will become a realistic content that can feel the five senses of human, which can be used whenever and wherever necessary, and also will become an emotional media that can stimulate human's emotions and enhance happiness. it means that it's not just communication.

Recently, with the rapid development of digital media technology, Realistic content that stimulates users' five senses is being used in various fields. This study focused on the case of the development of the Korea Industrial Complex Corporation's public relations center as the subject of the study to study the realistic content development process of public enterprises. First, the realistic content development process was divided into 10 stages and practical guidelines were presented to help develop realistic content in the future by presenting important development points and methods at each stage. Second, among the realistic content development processes, the importance of storytelling was analyzed at the scenario stage. Third, various methods of displaying content were analyzed. In the case of the Korea Industrial Complex Corporation's public relations center, it was proposed in three ways: story video, experience video, and media wall. It is suggested that the role of branding, promotion, and PR can be performed in one public relations center through an effective development process.

Realistic media comprised of metadata of the five senses to provide enhanced experiences by stimulating our memory and sensations have had an increasingly pervading effect in our daily lives. Many researchers and companies are in the process of developing their own authoring systems running on different platforms to serve realistic media, resulting in compatibility issues among the systems. To tackle these issues, the International Organization for Standardization have standardized the interface, data format, protocol, API, etc. required to provide the realistic media. In particular, the ISO/IEC 23005 standard, which is called MPEG-V in SC29/WG 11, has defined XML schemas for olfaction interaction based on electronic nose (E-Nose), and scent display. In this paper, the MPEG-V standard for olfaction interaction is reviewed, and a data flow diagram that can be used for olfactory interaction based on the MPEG-V standard was designed. In addition, the necessary schemas related to the E-Nose sensor for olfactory interaction was provided.

Due to the rapid development of Information and communication, the technology of multimedia presentation technology is evolving into the service that user can actively, realistically enjoy and play based on user's preference and taste not only for User's passive service. Especially, the industry related the realistic multimedia service that supports targeting Human emotion with the property of Human hearing is expected to be formed of the high value-added premium market. Audio technology is affected on human's emotion and the viewing environment around than video technology. Also the audio technology compared to video technology is a research part that appeals to human emotion and emphasize on psychological aspects. With this viewpoint, the development of intelligent and realistic audio technology needs highly specialty. In this study, "intelligent real-sound presentation technology" that support high quality and realistic audio and the "core technologies" that are composing of this will be introduced.

This paper deals with whether it is possible to find a way to solve the conflict between villagers and tourists by newly defining the difference between free village and public tourist destinations in Korea, reinforce the insufficient guidance and notification services with realistic media, and implement additional killing contents and attractions. Location-based service enables real-time docent service and emergency response and smart glass thread.

We propose an efficient method for synthesizing mesh-based realistic computer-generated hologram (CGH). In a previous nonanalytic mesh-based CGH synthesis, the angular spectrum of the two-dimensional (2D) plane is calculated using the fast Fourier transform (FFT) with the same size as the resolution of the final hologram. Because FFT increases the computation time as the size of the input matrix increases, the previous method has a problem: The higher the resolution of the hologram, the greater the computational load, thereby delaying synthesis time. In this study, when calculating the angular spectrum of the 2D plane in mesh-based CGH synthesis, we propose a method to calculate the angular spectrum by defining the 2D plane with an arbitrary size smaller than the resolution of the final hologram. The resolution adjustment method reduces the computation time and can be applied to occlusion culling and texturing for the realistic effect of mesh-based CGH. We describe the principle, error analysis, application of realistic effect, and experimental results of the proposed method.
