Abstract

LA PRESENTE INVENCION SE REFIERE A UNA GESTION DE MEMORIA DE SERVIDORES DE VIDEO PARA UN SERVIDOR DE VIDEO QUE TRANSMITE SEÑALES DE VIDEO (VS) A ESTACIONES DE USUARIOS, EN RESPUESTA A SEÑALES DE CONTROL EMITIDAS POR ESTAS ESTACIONES. ESTE METODO INCLUYE LAS FASES DE PROPORCIONAR UNA MEMORIA CONSTITUIDA POR UNA PLURALIDAD DE MEMORIAS DE ACCESO ALEATORIO(HD1/...HD$), Y SUBDIVIDIENDO CADA UNA DE LAS CITADAS SEÑALES DE VIDEO EN UNA PLURALIDAD DE BLOQUES DISTINTOS (BL1/...BLQ), CORRESPONDIENDO TIPICAMENTE CADA UNO A MENOS DE UN SEGUNDO DE LA SEÑAL DE VIDEO. TAMBIEN SE PROPONE INCLUIR EN ESTE METODO LA FASE DE ALMACENAR DOS BLOQUES CUALESQUIERA (BL1/...BLQ), QUE NORMALMENTE SE HAN DE RECUPERAR CONSECUTIVAMENTE DE LA MEMORIA EN MEMORIAS DE ACCESO ALEATORIO DISTINTAS (HD1/...HD4). DE ESTA FORMA, EL VIDEO INTERACTIVO COMPLETO EN SERVICIO DE SOLICITUD, DANDO EL CONTROL DE LAS ESTACIONES DE USUARIOS SOBRE LA FORMA EN QUE LOS BLOQUES SON RECUPERADOS DE LA MEMORIA, SE PERFECCIONA, COMO LO ES EL RITMO ENEL QUE UNA SECUENCIA PREDETERMINADA DE BLOQUES SE RECUPERA DE LA MEMORIA.
