In this paper, we present a Smart Audio/Video Mixing method (SmartAVM) for a software-based multipoint control unit (SW-based MCU) to provide an immersive video conferencing service. The SmartAVM determines the mixing mode to one of the true mixing, equal mixing, and main speaker decision-based mixing modes, according to the number of clients (i.e., human users) connected to the SW-based MCU. Then,...
Recently, the requirements for the real-sense media representation are increasing rapidly. Until now, most people mainly used the method SMSD on one device, but we need more than one device to play multiple audio/videos and multiple sensory effects of the real-sense media. Therefore, multi-track media synchronization and effect device synchronization algorithms are very important part of the real-sense...
Recently, various smart devices are interconnected within the home network environment and such smart home support collaborations between those devices based on the Web of Things (WoT). The evolving concept of the WoT in the smart home network not only provide a simply control by users either within or outside of the home, but requires to support ubiquitous accessibility and sharing resources. Current...
Web of Things (WoT), an advancement of the Internet of Things, enables networking devices to connect and communicate among people and various objects called “things” including networking devices as well as services in the distributed computing environments. Unlike in the many systems that exist for the Internet of Things, the Web of Things is about re-using the Web standards to connect the quickly...
Understanding player's cognitive state and emotional response is necessary to make serious games more challenging and enhance the quality of human-machine interaction and gaming experience. Previous emotion recognition using brain computer interfaces (BCIs) is either relying a large number of wet electrodes or combining both brain signals with other peripheral physiological signals. In this paper,...
In this paper, we propose a system and method for real-sense acquisition; and, more particularly, to a system for providing a real-sense effect by sensing ambient environment information through a sensor at a time when a camera photographs an image, extracting an effective data from the sensed information and creating real-sense effect metadata based on the extracted effective data, and a method for...
This paper designs and implements the sensory effect Aggregator with functions to get real-sense data used in the Realsense 4D Broadcasting Service interworking with heterogeneous multimedia devices. For considering broadcasting service aspects, we design the aggregator structure consisted of four parts: the sensing data collecting module, the sensing data handling module, the communication module...
Ongoing energy fault detection is a process of continuously comparing the actual performance of the building system calculated from the current monitoring data with the pre-determined target performance predicted by a mathematical model. In this paper, a noble ongoing energy fault detection method using multiple locally weighted linear regression models is proposed to provide more accurate prediction...
In these days, various 4D media service system which can give users a lot of special effects (eg., wind, heat, light, vibration, scent effect, ect.) according to the contents has been developed with the increment of 3D media consumptions. Also, standardizations for presenting events in the virtual world to the real world are continuously progressed in the MPEG forum, and companies have developed systems...
Recently, as the development of the 3D contents service, production of the real-sense media (ne-media) that user can feel physical effects by the scene of the movie has been increased. This kind of the ne-media uses the SMMD (Single Media Multiple Devices) method to give users enhanced effects with playing multiple devices rather than the SMSD (Single Media Single Device) method. To give this effect...
Recently, the requirements for the five sense media representation are arising rapidly. Until now, most people mainly used the method SMSD on one device, but we need more than one device to play multiple A/V and multiple sensory effects for effective five sense media representation. Therefore, multiple A/V device synchronization and multiple sensory effect device synchronization are very important...
In this paper, we investigate the use of explicit disjoint for the multipath routing to achieve cost-efficient operation of wireless sensor networks. The focus is on constructing completely disjointed multiple paths between the source of sensing stimulus and the destination of gathered sensor data. We propose simple schemes for multipath construction based on explicit multiple anchor nodes. For the...
This paper has a background of SMMD (single media multi device) control technology for causing various actual feeling effects about one media source. SMMD technology adds metadata controlling arbitrary multiple devices in one MPEG-4 media. A home server produces a control command from metadata and delivers control message to a sensory effect device using the ZigBee communication. A device produces...
