This paper describes development of a distributed framework for creating mobile mixed reality (MR) systems. The goal of the framework is providing the same MR space for a variety of mobile devices which connect via wireless network. This paper discusses a design policy of our framework, system architecture for supporting diverse mobile devices, including an easy-to-implement script language for developing...
Due to the growth of sensor use, such as environmental sensors and street cameras, sensor data stream delivery, the delivering of sensor data through cyclic collection, is attracting considerable attention. Our research team proposed some peer-to-peer streaming methods named LCF, LLF and LLF-H for distributing communication loads when delivering sensor data streams with different data collection cycles...
To capture and record a multi-view video is inconvenient due to needing mechanism for synchronization between cameras and computational cost for video coding. This paper presents a multi-eyed network camera which has five fixed HD camera modules and a gigabit Ethernet port. Only one LSI controls the camera modules and encodes all captured videos. To reduce computational complexity and keep synchronization,...
To show a computer screen on a large display, so far, wired cable connections like VGA, HDMI, and DisplayPort are mainly used. Recently, wireless display technology is becoming popular, especially on mobile devices like PCs, tablets, and smartphones. “Tap to Display” is a connection method triggered by an NFC tap operation. It enables users to show the desktop screen of his PC on the destination Miracast...
With the fast development of mobile technologies and wireless Internet access, video streaming share grows rapidly. New HEVC (High Efficiency Video Codec) standard was introduced by ITU-T in 2013. It increases compression rate and, in the same time, computational efforts. Thus development of efficient decoding systems for mobile platforms becomes actual problem. This paper is dedicated to analysis...
With the increasing demand for video streaming in mobile environment, we have been tackling a research on throughput prediction based on the measurement history data in order to improve service quality[1][2]. Since throughput fluctuation occurs sharply in mobile environment, useless packet loss or congestion occurs when available network bandwidth is insufficient compared to the bit rate of video...
