Abstract

METODO Y DISPOSITIVO DE PROCESAMIENTO DE DATOS ASINCRONOS. APLICABLE A SISTEMAS DE PROCESAMIENTO DE SEÑALES DE VIDEO COMPRIMIDAS, QUE GARANTIZA EL MANTENIMIENTO DEL SINCRONISMO DE LAS CELULAS CON FORMATO MODO DE TRANSFERENCIA ASINCRONO (MTA) EN REDES DE COMUNICACIONES QUE NO SON MTA; Y QUE UTILIZA SISTEMAS CODIFICADORES Y DECODIFICADORES DE VIDEO EXISTENTES PARA REDES MTA. EL METODO CUENTA CON UNA PRIMERA ETAPA DE LECTURA DE LAS CELULAS MTA PROCEDENTES DEL CODIFICADOR DE VIDEO Y DETERMINACION DE SI CADA CELULA CONTIENE INFORMACION UTIL O NO. CUENTA CON UNA SEGUNDA ETAPA DE ELIMINACION DE LAS CELULAS VACIAS Y ENVIO DE LAS CELULAS UTILES A LA RED DE COMUNICACIONES. CUENTA CON UNA TERCERA ETAPA DE RECEPCION Y LECTURA DE LAS CELULAS UTILES RECIBIDAS DE LA RED DE COMUNICACIONES DETERMINANDOSE PARA CADA CELULA SI ES DE SINCRONISMO O DE DATOS. INCLUYE UNA CUARTA ETAPA EN LA QUE SI LA CELULA RECIBIDA ES DE DATOS SE ENVIA AL DECODIFICADOR DE VIDEO MIENTRAS QUE SI ES DE SINCRONISMO SE CALCULA UN TIEMPO DE ESPERA DURANTE EL CUAL SE GENERAN Y ENVIAN CELULAS VACIAS AL DECODIFICADOR DE VIDEO, ENVIANDOSE LA CELULA DE SINCRONISMO UNA VEZ TRANSCURRIDO DICHO TIEMPO DE ESPERA. EL DISPOSITIVO LLEVA A CABO LAS DISTINTAS ETAPAS DEL METODO.METHOD AND DEVICE FOR PROCESSING ASYNCHRONOUS DATA. APPLICABLE TO COMPRESSED VIDEO SIGNALS PROCESSING SYSTEMS, WHICH GUARANTEES THE MAINTENANCE OF CELL SYNCHRONISM WITH ASYNCHRONOUS MODE OF TRANSFER FORMAT IN COMMUNICATION NETWORKS THAT ARE NOT MTA; AND THAT IT USES EXISTING VIDEO ENCODERS AND DECODERS FOR MTA NETWORKS. THE METHOD HAS A FIRST STAGE OF READING MTA CELLS FROM THE VIDEO ENCODER AND DETERMINATION OF WHETHER EACH CELL CONTAINS USEFUL INFORMATION OR NOT. IT HAS A SECOND STAGE OF ELIMINATION OF EMPTY CELLS AND DELIVERY OF USEFUL CELLS TO THE COMMUNICATION NETWORK. IT HAS A THIRD STAGE OF RECEPTION AND READING OF USEFUL CELLS RECEIVED FROM THE COMMUNICATION NETWORK DETERMINING FOR EACH CELL IF IT IS SYNCHRONISM OR DATA. IT INCLUDES A FOUR STAGE IN WHICH IF THE RECEIVED CELL IS OF DATA, IT IS SENT TO THE VIDEO DECODER, WHILE IF IT IS OF SYNCHRONISM, A WAITING TIME IS CALCULATED DURING WHICH THEY ARE GENERATED AND SEND EMPTY CELLS TO THE VIDEO DECODER, SENDING SYNCHRONISM ONCE THIS TIME-OUT HAS PASSED. THE DEVICE CARRIES OUT THE DIFFERENT STAGES OF THE METHOD.
