Abstract

"SISTEMA E MéTODO PARA GRAVAR DADOS EMPURRADOS". Um método para gravar fluxos de dados interativos empurrados de um programa. Um fluxo de dados empurrado é difundido para uma estação de recepção. O fluxo de dados inclui um ou mais objetos de dados. O fluxo de dados pode também fazer referência a objetos de dados ao vivo que são pretendidos para consumo imediato e tornam-se obsoletos depois disso. O fluxo de dados pode incluir uma tabela de arquivos e propriedades de objeto correspondendo aos objetos de dados. Quando o fluxo de dados é recebido pela estação de recepção, os objetos de dados individuais são extraídos do fluxo de dados. Os objetos de dados, as propriedades de objeto acompanhantes e a tabela de arquivos são então armazenados em um dispositivo de armazenamento. Os objetos de dados que são externos ao fluxo de dados ou ao programa (por exemplo, objetos de dados de outros carrosséis) são recuperados e são também armazenados. Objetos de dados ao vivo não são armazenados, mas referência a estes objetos de dados são armazenadas, de modo que quando os programas são executados, as versões correntes dos objetos de dados ao vivo referenciados podem ser utilizadas. Um programa não sendo gravado pode conter objetos de dados que são sinalizados para serem colocados no cache de memória, os quais são gravados automaticamente. Por conseq³ência, outros programas podem subseq³entemente acessar os mesmos a partir da gravação quando eles são executados.
