This paper draws a proposal of a set of parameters and methods for accuracy evaluation of visual inspection systems. The case of a monochrome board is treated ,but practically all conclusions and methods may be extended for colour acquisition. Basically, the proposed parameters are grouped in five sets as follows:Internal noise;Video ADC cuantisation(More)
The LPC-MPE synthesis method is an alternative method used for obtaining a better quality of the generated vocal signal, that can be easily implemented in vocal signal coding-decoding systems. Using the method in text-to-speech systems is more difficult because of the modification that must be done on the synthesized vocal signal in order to superimpose(More)
– This paper presents a study of audio-video streaming using the additional possibilities of a DVB-S card. The board used for experiments (Technisat SkyStar 2) is one of the most frequently used cards for this purpose. Using the main blocks of the board's software support it is possible the implement a really useful and full functional system for(More)
This paper presents some aspects related to test process of an advanced video system used in remote IP surveillance. The system is based on a Pentium compatible architecture using the industrial standard PC104+. First the overall architecture of the system is presented , involving both hardware or software aspects. The acquisition board which is developed(More)
This paper presents some aspects related to the DVB (Digital Video Broadcasting) investigation. The basic aspects of DVB are presented, with an emphasis on DVB-T version of standard. The main purpose of this research is to analyze the way that the transmission of the transport streams is realized in case of the Terrestrial Digital Video Broadcasting(More)
are analyzed, which will be transmitted to a Linux VLC client through means of the aggregation and access servers. The first stream is generated in real time by a capture camera, processed by the encapsulated VC-1 encoder and sent to the Media Server, while the second one is of VoD(Video on Demand) type and the third one will be handled by DVBViewer through(More)
—The paper presents an overview of the main methods used to improve the efficiency of DVB systems, based on multiplexing, through a study on the impact of the multiplexing methods used in DVB, having as a final goal a better usage of the data capacity and the possibility to insert new services into the original DVB Transport Stream. This study revealed that(More)
This paper present the mathematical fundaments and experimental study of an algorithm used to find the optimal position for the camera lens to obtain a maximum of details. This information can be further applied to a appropriate system to automatically correct this position .The algorithm is based on the evaluation of a so call " resolution function " who(More)
– This paper presents some experiments regarding applications development on high performance media processors included in Philips Nexperia Family. The PNX1302 dedicated DVB-T kit used has some limitations. Our work has succeeded to overcome these limitations and to make possible a general-purpose use of this kit. For exemplification two typical(More)
The paper presents an implementation and tests of a simple home entertainment distribution architecture (server + multiple clients) implemented using two conventional cabling architectures: CATV coaxial cable and conventional Ethernet. This architecture is created taking into account the " Home gateway " concept present in most attempts to solve the problem(More)
