Estas compa as, junto con LG, son los partners de HISPASAT en este proyecto.

Ignacio Sanchis, director de Negocio de Hispasat, ha presentado el canal, destacando la precisi n y la fidelidad con que la tecnolog a UHD transmite las obras de arte del museo, y el rigor con que reproduce los vol menes, las texturas y los colores de las pinturas que alberga. Esta nitidez y precisi n resultan esenciales para transmitir al espectador una visi n de estas obras ajustada a la realidad, y son tambi n importantes a la hora de visualizar la naturaleza, la arquitectura o los espect culos deportivos .

Sanchis ha se alado que el sat lite se configura como la plataforma id nea para el desarrollo de los servicios en UHD debido a su cobertura universal, elevada capacidad y gran ancho de banda, imprescindible para transmitir gran cantidad de informaci n en alta calidad , y ha recordado que HISPASAT ha sido pionera en la transmisi n de contenidos en UHD v a sat lite, habiendo realizado emisiones en calidad 4K en Brasil, Espa a y varios pa ses europeos.

El nuevo canal se transmite en MPEG-4 a una velocidad de 35 Mbps, as como, de forma experimental, en el nuevo formato HEVC (High Efficiency Video Coding) a una velocidad de 18 Mbps, lo que lo convierte en el sistema de transmisi n v a sat lite m s eficiente del mundo en este momento. Los contenidos, codificados en dichos formatos, se transmiten bajo el est ndar DVB-S2 por medio del sat lite Hispasat 1E en su cobertura europea. Est previsto emitir tambi n en Norteam rica y Latinoam rica dentro de unos meses.

El quipo de Ingenier a de Clientes de Hispasat, Pemio Best Young Professional Paper en IBC 2013 El equipo de Ingenier a de Clientes de Hispasat, liderado por In s Sanz, ha obtenido el premio Best Young Professional paper IBC2013 que se otorga en esta feria al mejor art culo presentado por menores de 30 a os. El estudio, titulado Retos y oportunidades para el despliegue de la UHDTV, analiza uno de los elementos clave en el futuro de la industria audiovisual: la televisi n en ultra alta definici n (UHD). El texto analiza los retos tecnol gicos a los que se enfrenta la industria audiovisual en su intento de conseguir el xito en la televisi n de ultra alta definici n.

El despliegue de esta tecnolog a es un factor fundamental para el crecimiento, no s lo de las plataformas DTH (Direct to Home) por sat lite, sino tambi n de otras plataformas de difusi n como el cable o la TDT.

Para comprender plenamente el progreso y los desaf os tecnol gicos pendientes de afrontar, tanto desde una perspectiva t cnica como desde un punto de vista empresarial, este art culo se centra en la experiencia real de Hispasat en la transmisi n en ultra alta definici n v a sat lite, y destaca la aplicaci n de estas tecnolog as en el dise o de nuevos servicios UHD aprovechando las excelentes prestaciones de los sat lites Hispasat 1E en banda Ku en Europa y Amazonas 3 en banda Ka para Am rica.
