Este volumen masivo de datos ha dado lugar a una fuerte demanda en el desarrollo de aplicaciones para la transmisi\u00f3n de v\u00eddeo de forma eficiente. Los c\u00f3digos correctores de errores han sido estudiados para conseguir la comunicaci\u00f3n fiable desde hace varias d\u00e9cadas. Sin embargo, las t\u00e9cnicas de codificaci\u00f3n ideales para la transmisi\u00f3n de v\u00eddeo son fundamentalmente diferentes de los c\u00f3digos de correcci\u00f3n de errores cl\u00e1sicos. Con el fin de optimizar la transmisi\u00f3n de los datos surgen muchas restricciones en la codificaci\u00f3n y decodificaci\u00f3n secuencial, y, como tales, deben tener una estructura inherentemente convolucional. Tales restricciones conducen a nuevos y fascinantes problemas abiertos en el dise\u00f1o de c\u00f3digos de correcci\u00f3n de errores. En esta charla se pretende mirar desde una perspectiva te\u00f3rica del sistema a estos problemas. En particular, se propone la utilizaci\u00f3n de c\u00f3digos convolucionales.<\/span><br \/>\n<span style=\"color: #000000\"><strong>Breve Bio:<\/strong><\/span><br \/>\n<span style=\"color: #000000\">Diego Napp es doctor por la Universidad de Groningen (Holanda, 2008).

Video already accounts for over 50% of the internet traffic today and mobile video traffic is expected to grow by a factor of more than 20 in the next five years. This massive volume of data has resulted in a strong demand for implementing highly efficient approaches for video transmission. Error correcting codes for reliable communication have been studied for several decades. However, ideal coding techniques for video streaming are fundamentally different from the classical error correction codes. In order to be optimized they must operate under lowlatency, sequential encoding and decoding constrains, and as such they must inherently have a convolutional structure. Such unique constrains lead to fascinating new open problems in the design of error correction codes. In this talk we aim to look from a system theoretical perspective at these problems. In particular we propose the use of convolutional codes.<br \/>\n<strong>Brief Bio:<\/strong><br \/>\nDiego Napp carried out his PhD at the University of Groningen (The Netherlands, 2008). His research interests lie in the intersection of the broad areas of Systems &amp; control theory, Algebra and Coding theory. After a post-doc in Portugal and a Juan de la Cierva fellowship in Valladolid, he is currently holding a \u00abFCT researcher\u00bb position (analogous to Ramon y Cajal) at the University of Aveiro in Portugal. In the last few years he has focused on convolutional codes which are basicaly linear systems over finite fields. In 2012, he was a visiting researcher in the Department of Mathematics of the Universities of Notre Dame (US) and Melbourne (Australia). He has giving invited talks at the he Departments of Mathematics of the Universities of British Columbia (Canada), Zurich (Switzerland), Notre Dame (US), Melbourne (Australia), Javeriana de Cali (Colombia) among many others. He has over 30 high quality publications in the different areas of applied mathematics, electrical engineer and coding theory.[:]<\/p>","protected":false},"excerpt":{"rendered":"<p>[:es]T\u00edtulo: Teor\u00eda de C\u00f3digos: c\u00f3digos convolucionales.<br \/>\nPonente:  Diego Napp<br \/>\nFecha: 20\/07\/2016 12:00 h<br \/>\nLugar: Sala de Seminarios, Edificio Torretamarit<br \/>\nResumen:<br \/>\n Una piedra angular de nuestra sociedad digital se deriva del crecimiento exponencial del tr\u00e1fico multimedia en general y, de v\u00eddeo en particular.
