Abstract

UN SISTEMA DE DIRECCION DE DISTRIBUCION DE VIDEO UTILIZA UNA BIBLIOTECA DE VIDEO COMPARTIDA Y UNA RED DE AMPLIA AREA PARA DISTRIBUIR LOS ARCHIVOS DE VIDEO A CACHES LOCALES SOBRE LAS REDES DE AREA LOCAL QUE SIRVEN A UN SUBGRUPO DE ESTACIONES DE VISIONADO LOCAL. UNA COMBINACION DE ACCESOS DE CACHE LOCAL DIRECTO, ACCESOS DE CACHE LOCALES FUTUROS PROGRAMADOS Y LA DISTRIBUCION DE VELOCIDAD DE EMPAREJAMIENTO DE LOS ARCHIVOS DE VIDEO HACE QUE EL SISTEMA TOTAL SEA TANTO EFICIENTE COMO ECONOMICA. EN PARTICULAR, LA PRESUPERFICIE ALMACENADA LOCALMENTE DE UN ARCHIVO DE VIDEO PUEDE SER VISIONADA INMEDIATAMENTE SOBRE LA RED DE AREA LOCAL MIENTRAS EL BALANCE DEL ARCHIVO DE VIDEO SE TRANSMITE DESDE LA BIBLIOTECA REMOTA DE VIDEO.
