The paper presents a cheaper alternative to the traditional way to implement experiments in Embedded DSP research or teaching laboratory. In this approach, in the test bench, the classical instruments (signal generator, oscilloscope, spectrum analyzer) are replaced by the computer itself. Simple signal generation and acquisition applications make possible to generate and visualize the signals in DSP,...
Internet of Things extends to the objects and the sensors with computing capability and connectivity and affects all our life domains: technical, social or economic. These components are not usually considered computers, however they allow fetching and exchanging data. This paper presents an approach to implement a smart wearable system based on the AT Mega 32U4 microcontroller, which is capable to...
Hearing aids are a field of medical devices, powered by digital signal processing techniques. Development of hearing aid modules is realized usually in the first stages using prototyping boards equipped with specialized Embedded DSP. The paper presents a generic model of a hearing aid developed on a DSP development system. The method used to develop and prototype the model (Rapid prototyping) is the...
The paper presents the main aspects of the design of a Wi-Fi remote controlled car. A classical RC (Radio Controlled) car architecture is replaced by one based on the Intel Galileo Platform (Arduino compatible) and the car may be controlled by a mobile device. In order to allow the Wi-Fi connection between the tablet and the car a PCI (Peripheral Component Interconnect) extension card is connected...
Wireless sensors networks (WSNs) became a successful alternative to cabled systems used for surveillance or monitoring, allowing more freedom to patients or elderly persons and also lower costs for implementation improving the quality of medical care. The paper presents a possible solution for a surveillance system based on a BeagleBoard-XM card, connected to a video camera and emulates the data provided...
Transition to TV digital distribution finished in most countries. In cable networks, analog transmission will continue to work for their users. Studies evaluating the mutual interference between terrestrial (DVB-T and analog TV) and cable standards are rare, probably because it is considered that the two transmission media (the air and cable) are sufficiently distinct to avoid influencing each other...
The speaker diarization system LIUM was developed for broadcast news data, but in this paper we employed it to evaluate the diarization performance over Romanian audio files of parliamentary speeches with different challenges (interruptions, noise, overlapping of speaker discourses etc.). More than 21 hours of speech belonging to few hundreds of speakers were used to evaluate the automatic process...
The paper presents an practical analysis of combined DVB-C and IPTV implementation in an unique architecture. The advantages of each simple architecture are examined and the basic principles of unification are examined. Both aspects, client side and server side, are included in the analysis, and an implementation scenario with an evaluation of final costs for provider and client are established. In...
The paper proposes solutions for data networks distribution of audio-video information based on the Digital Video Broadcasting over Internet Protocol (DVB IP) standard. Principles of DVB IP standard are described along with two practical methods. A providers proprietary solution (SAT-IP) is presented compared to an open server based system. The server distributes the transport streams over an IP network,...
This paper focuses on the development and implementation of a biometric system based on iris. Our approach is different from the most common solution presented in the references, as it proposes a mixture between the wavelet and the TESPAR DZ approaches applied to images. The results provided by our experiments are close to those presented in the literature.
Paper describes briefly the basic concepts and a practical implementation for an original generic platform able to acquire, create and distribute IPTV content, using as primary sources DVB or locally stored video content. A clearly unusual, original feature, is the fact that the system includes both components of the bridge, RF/baseband DVB processing and IPTV streaming elements in an integrated architecture...
