Abstract

Patente de Invenção <B>"PROCESSADOR DE DADOS MULTILINHA"<D>. Em um primeiro aspecto, a presente invenção compreende um aparelho para processar dados audiovisuais digitais, em particular, um conjunto receptor / decodificador para um sistema de televisão digital, compreendendo um ou mais dispositivos de hardware para transmissão e recepção de dados, os dispositivos de hardware tendo pelo menos um sistema operacional de hardware associado (4100), o conjunto receptor / decodificador compreendendo ainda um sistema de processamento de dados, incluindo uma máquina virtual multilinha (4250), adaptado para, entre outras coisas, receber mensagens de evento sinalizadas pelo sistema operacional de hardware e atribuir os eventos objeto correspondentes (4564) a uma ou mais linhas, e em que uma fila incluindo um evento objeto pode ser suspensa durante o transcorrer da sua execução para permitir a execução de outra linha. Vista de um segundo aspecto, a presente invenção se refere a um para processar dados audiovisuais digitais, compreendendo um sistema de processamento de dados incluindo uma primeira máquina virtual adaptada para, entre outras coisas, receber códigos gravados em uma linguagem interpretativa baixada via um ou mais dos dispositivos de hardware, a dita máquina virtual sendo adaptada para distinguir entre o código gravado em pelo menos duas linguagens interpretativas, na dependência da estrutura do código recebido e passar esse código para um meio interpretador correspondente para interpretação e execução, em particular, com referência a uma biblioteca de função comum ou específica. Vista de um terceiro aspecto, a presente invenção compreende um aparelho para processar dados audiovisuais digitais incluindo um sistema de processamento de dados, incluindo uma memória e um gerenciador de memória, para alocar e armazenar objetos na memória, e no qual um primeiro conjunto de objetos é alocado pelo gerenciador de memória com referência a um conjunto de alças, cada alça incluindo uma referência para o endereço da memória de um objeto correspondente, e no qual um segundo conjunto de objetos é alocado e armazenado diretamente na memória sem referência a uma alça.
