This paper describes the new functionalities introduced to the source code of the decoder box model SDP160 of the SOYEA brand to obtain, adjust and correct the Signal Level values and the Signal to Noise Ratio of the DTMB digital television signal received. (Digital Terrestrial Multimedia Broadcast) with 6 MHz channeling. These modifications to the...

This paper describes the development on LabVIEWof a virtual instrument, intended to perform real time analysis of the Digital TV signal measurements provided by a sensor. The instrument graphically displays real time information about the signal level and signal-to-noise ratio. It also shows specific information of the DTMB modulation, such as numb...

Currently in LACETEL®, Research and Development Telecommunications Institute, has been developed a solution for monitoring the radio spectrum in commercial television bands. To achieve this goal, the deployment of a set of geographically distributed sensors is planned, in order to perform periodic sweeps of the spectrum, measuring the fundamental p...

Actualmente en LACETEL®, Instituto de Investigación y Desarrollo de Telecomunicaciones, está siendo desarrollada una solución para la monitorización del espectro radioeléctrico en las bandas comerciales de televisión. Para ello se prevé el despliegue de un conjunto de sensores distribuidos geográficamente, los cuales realizaran barridos periódicos...

Spectrum scarcity has become a challenge for the growing demand of wireless services. Paradoxically, although most of the sub-1-GHz spectrum is assigned it is underutilized in the space and time domain. Several surveys demonstrate a spectrum usage efficiency lower than 20%. Cognitive Radio technologies has been proposed as a long-term solution for...

Currently our country does not have a national solution for the insertion or extraction of TV services form the Digital TV transmission flow. The present work shows the development of a software application that models the essential stages of the re-multiplexing process of an MPEG-2 Transport Stream, describing in general how this process occurs, a...

H.264/AVC and AVS, video coding standards, are currently deployed in set-top boxes sold in Cuba. LACETEL, Research and Development Telecommunications Institute, has participated, conducted and reported the results of various benchmark tests that show a similar performance between these standards. H.264 is currently the most mature and has more indu...

RESUMEN Las técnicas de estimación de calidad de video son de gran utilidad para los operadores de servicio y generadores de contenido, dado que permiten monitorear y evaluar la imagen recibida. En un sistema de procesamiento y transmisión de video, la señal siempre está expuesta a degradaciones, distorsiones, pérdidas de cuadros y otros fenómenos...

LACETEL, Research and Development Telecommunications Institute, as part of the technology assimilation associated with the adoption of the standard DTMB in Cuba, perform the verification for assessment conformity of DTV commercial receivers. This paper aims to provide reference material to manufacturers of DTV receivers, in order to obtain better p...

H.264/AVC and AVS are 2nd generation video coding standards with differences in some aspects like IPR policy, terms of licensing and royalty cost. The ways these standards are conform have a direct influence on the licenses and royalties imposed by the Patent Pool. MPEG LA is an independent and profit organization, located in United States of Ameri...
