Abstract

"MéTODOS PARA FORNECER SERVIçOS DE VìDEO SOB DEMANDA PARA, SISTEMAS DE TRANSMISSãO". Um método de envio de dados para um cliente por intermédio de um servidor de controle central (102) para fornecer serviços de dados sob de manda que consiste nas etapas de: recebimento de um arquivo de dados, especificação de um intervalo de tempo, divisão do arquivo de dados em vários blocos de dados com base no intervalo de tempo de modo que cada bloco de dados seja exibido durante um intervalo de tempo, determinação de um número requerido de slots de tempo para enviar o arquivo de dados, alocação para cada slot de tempo pelo menos no primeiro dos vários blocos de dados e opcionalmente um ou mais blocos de dados adicionais, de modo que seja iniciado a partir de qualquer slot de tempo; (i) o arquivo de dados pode ser exibido acessando-se o primeiro dos vários blocos de dados; (ii) em um slot de tempo consecutivo, um próximo bloco de dados seq³encial para um bloco de dados exibido anteriormente está disponível para exibição; e (iii) repetição da etapa (ii) até que todos os vários blocos de dados para o arquivo de dados tenham sido exibidos, e envio dos vários blocos de dados com base na etapa de alocação."METHODS FOR PROVIDING VIDEO SERVICES ON DEMAND FOR TRANSMISSION SYSTEMS". A method of sending data to a client via a central control server (102) for providing on-demand data services consists of the steps of: receiving a data file, specifying a time interval, splitting the data. data file into multiple data blocks based on time slot so that each data block is displayed over a time slot, determining a required number of time slots to send the data file, allocation to each data slot time at least in the first of several data blocks and optionally one or more additional data blocks, so that it is started from any time slot; (i) the data file may be displayed by accessing the first of several data blocks; (ii) in a consecutive time slot, a next sequential data block for a previously displayed data block is available for display; and (iii) repeating step (ii) until all the various data blocks for the data file have been displayed, and sending the various data blocks based on the allocation step.
