Abstract -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(More)
This paper presents the basic concepts in industrial video acquisition boards evaluation. The testing procedure is focused on real accuracy test (SNR measurements) and was applied to evaluate two main chipsets used in modern applications: Philips SAA713x and Conexant (Bt8xx and CX2338x). Simple programs developed to evaluate the accuracy performance are(More)
This paper describes a methodology to generate Transport Streams using low cost domestic equipment, in some experiments involving DVB (Digital Video Broadcasting). First the basic aspects of DVB are described followed by a short description of the equipment used to build the DVB TS generator. The results allowed building a TS generator which can be used 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)
The paper is proposing a study and practical experiments of testing methods in digital television, transmitted in Digital Video Broadcasting standard. The main objective of the research presented in this paper was to establish if the testing tools designed and validated for DVB-S, are useable to evaluate DVB-S2. This is important in educational environments(More)
This paper presents aspects of a simple methodology to evaluate satellite link quality (especially for downlink segment) using accessible technologies and Satellite PC boards (DVB-S). Traditional methods are based on high end testing communication equipment, allowing better results in precision, but with significantly higher costs, not entirely justified in(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)
