  • In this paper, the existing domestic HVAC systems, devices TCP / IP does not support the most, thereby, not performed remote management, it is necessary to regularly field service, inefficiency and cost bring a burden. This is through a comparison of the IoT-based primary, real-time protocol of what has become a hot topic recently, to be able to control and real-time monitoring through the CCU device in the HVAC system. Compare for this Internet of Things device for real-time monitoring and control of the XMPP, CoAP, MQTT main real-time protocol is used on. Finally, flexibility, light weight, based on MQTT a two-way messaging protocols with reliable message delivery, implements the protocol on the real-time HVAC system in the cloud platform.

  • A watermarking for copyright protection of digital contents for broadcasting have to be made for a real-time system. In this paper, we propose a real-time video watermarking system which is hardware-based watermarking system of SD/HD (standard definition/high definition) video with the STRATIX FPGA device from ALTERA. There was little visual artifact due to watermarking in subjective quality evaluation between the original video and the watermarked one in our experiment. Embedded watermark was extracted after robustness testscalled natural video attacks such as A/D (analog/digital) conversion. Our implemented watermarking hardware system can be useful in movie production and broadcasting companies that requires real-time contents protection systems.

  • A Digital Broadcasting Satellite (DBS) receiver converts digital A/V streams received from a satellite to analog NTSC A/V signals in real-time. Multi-tasking is an efficient way to improve the utilization of the processor core in real-time applications. In this paper, we propose a hybrid approach with a balanced trade-off between hardware kernel and multi-tasking programming to increase a system throughput. First, the schedulability of the critical hard real-time tasks in the DBS receiver is verified by using a simple feasibility test. Then, several soft real-time tasks are thoughtfully programmed to satisfy functional requirements of the system.

  • In this paper, we develope a LOB(Limit Order Book) analyzing tool for an automated trading system, which features real-time and offline analysis of LOB data in conjunction with execution data. The 10-tier LOB data analyzer developed in this paper, which contains ask/bid prices and the execution data, receivs transaction requests in real-time from the Kiwoom Open API+ server. In the OnReceiveTrData event, the transaction data from the server is received and processed. The real-time data, triggered by the transaction, is received and processed in the OnReceiveRealData event. These two types of data are stored in a database and replayed in the same way as if it were a real-time situation in simulation mode. The LOB data are selectively read and analyzed in a necessary time points. The tool provides various features such as bar chart analysis and pattern analysis of the total shares on the bid side and ask side, which are used to develop a tool to accurately determine the timing of stock trading.

  • High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.

  • A present experimental broadcasting is service compatible to delivery left view and right view of a dual stream for backward compatible with 2D device. It has a limitation of quality for a transmission of dual stream in terrestrial bandwidth 19 Mbps. This paper proposes adjunct terrestrial-3D broadcasting system which can provide a stable quality beyond a limitation of quality from fixed bandwidth. It proposes the system that composes a high quality stereoscopic video through synchronizing Real time broadcasting and Non Real Time broadcasting Regardless of the terrestrial bandwidth. So this paper tries to analyze each technique of Real-Time broadcasting and NRT broadcasting, and verify this proposal through the technique of an algorithm that we can implement NRT adjunct high quality 3DTV system and the experiments.
