In this paper, we propose a simple and effective vision-based tracking controller design for autonomous object tracking using multicopter. The multicopter based automatic tracking system usually unstable when the object moved so the tracking process can’t define the object position location exactly that means when the object moves, the system can’t track object suddenly along to the direction of objects movement. The system will always looking for the object from the first point or its home position. In this paper, PID control used to improve the stability of tracking system, so that the result object tracking became more stable than before, it can be seen from error of tracking. A computer vision and control strategy is applied to detect a diverse set of moving objects on Raspberry Pi based platform and Software defined PID controller design to control Yaw, Throttle, Pitch of the multicopter in real time. Finally based series of experiment results and concluded that the PID control make the tracking system become more stable in real time.

In this paper, in today’s highly complex video and broadcast operations, broadcasters are constantly challenged to reliably deliver low-latency, high-quality video to multiscreen audiences on-air and online. The Adaptive Bit Rate (ABR) protocols enable internet video to a wide range of multiscreen devices. However, video quality is often marginal and would prove unacceptable for valued linear broadcast content delivered to the Big Screen today. The Media information processing technology advances in ABR enables service providers to take control and offer quality managed linear video services to ALL screens in the home, including the Big Screen, with a single unified IP Video infrastructure. The New Multiscreen-Assisted ABR (MSA-ABR) delivery management system proposed using Cloud based multicast-assisted ABR for a broadcast facility that performs routing of contribution content and online publishing services within a virtual, centralized cloud infrastructure.

오늘날 매우 복잡한 비디오와 방송 작동들 속에서, 방송사들은 확실히 방송중이나 온라인에서 멀티스크린 시청자들에게 높은 품질 과 저지연을 방송하는데 거듭 어려움을 겪는다. 적응 비트율(ABR) 프로토콜들은 인터넷비디오가 다양한 멀티스크린 장치를 가능하 게 해준다. 하지만 비디오 품질은 종종 중요하지 않고 오늘날 대형화면에 방송되고 가치 있는 선형 방송 컨텐츠에서는 받아들일 수 없다는 것이 입증될 것이다. ABR에서 미디어 정보 처리 기술은 서비스 제공자들이 제어를하고 집에 모든 스크린에 선형 비디오 서비스가 관리된 품질을 제공한다. 그리고 그것은 단일화된 IP 비디오 사회기반시설을 가진 큰 대형화면을 포함한다. 새로운 멀티스 크린 보조 ABR (MSA-ABR)은 기부 컨텐츠, 가상 속에 온라인 출판 서비스, 집중 클라우드 사회기반시설의 절차를 수행하는 방송 시설을 대한 멀티스크린 보조 ABR (MSA-ABR)을 기반으로하는 클라우드를 사용하도록 제안된 관리시스템을 가져다 준다.

In these days, the lighting system integrated with various application are needed to be dynamic and adaptive with lighting data rate control, and the data transmission methods are being studied to use effectively in many systems. The progressive development of lighting system extends the use of rear light of various vehicles to communication medium for transmission of data in addition to luminary function in driving with rear light turned on. The vehicles are designed to be operated with different speed and different light luminary devices, because the transmission method should be standardized to use the vehicle rear light system based data transmission for all kinds of vehicles. This paper proposes open-source controller applicable to construction site trailer vehicles as an lighting transmitter to transmit data on optical channel medium connected on vehicle. In this approach, vehicle transmit data without adding any additional resources by connecting micro-controller and the receiver decodes the data. The vehicle rear light based transmission system model can be operated on data rate from tens of b/s to Kb/s.

Self-powered system (SPS) will be the promising power source in this modern era where the customized electronics gadgets are ruling the world. However, the impedance matching (energy harvester and storage), high-cost, and long-time durability of SPS in the previous report stop them from further development towards commercialization. The development of new materials with the property of both energy harvesting and storage is the utmost importance to extend the application of SPS. In this work, we report the bifunctional properties of free-standing paper-like carbyne-enriched carbon (P-CeC) as both energy harvester (triboelectric nanogenerator) and storage unit (supercapacitor) in the formulated SPS unit as a first report. The changes in the work function & surface potential of P-CeC film were carefully investigated using KPFM and UPS study. The fabricated C-CeC TENG shows far superior performance compared to the state of art of the polymer-based TENG. In addition, the energy storage performance of P-CeC SSC was systematically studied and evaluated. Finally, the self-charging capability of this P-CeC SPS is demonstrated, which charge 750 mV (380s) with energy storing efficiency of 93.75 %. This result shows that the development of bifunctional materials has great potential for the maintenance-free system towards customized electronics gadgets.

Environment Adaptive Sound Localization for Multi-Channel Surround Sound System

이윤배,마리아판 비나야감,조주필,이선희 한국인터넷방송통신학회 2016 Journal of Advanced Smart Convergence Vol.5 No.4

Recent development in multi-channel surround is emerging in various formats to provide better stereoscopic and sound effects to consumers in recent broadcasting. The ability sound localize the sound sources in space is most considerable design factor on multi-channel surround system for human earing perception model. However, this paper propose the change of the sound localization according to the spacing of the speakers, which is not covered in the existing research focus on sound system design. Presently the sound system uses the position and number of the speakers to localize the sound. In the multi-channel surround environment, the proposed design uses the sound localization is caused by the directional characteristics of the speaker, the distance between the speakers and the distance between the listener and the speaker according to the directivity is required. The proposed design is simulated using virtual measurement with MATLAB simulation environment and performances are measured.
