Abstract

1 / 1 resumo “dispositivo, mã‰todo e sistema para suprimento de conteãšdo, programa, e, dispositivo de terminal” a presente descriã§ã£o refere-se a um dispositivo para suprimento de conteãºdo, a um mã©todo para suprimento de conteãºdo, a um programa, a um dispositivo de terminal e a um sistema para suprimento de conteãºdo, que sã£o capazes de implementar mudanã§a de canal rã¡pida entre canais em dash. este dispositivo para suprimento de conteãºdo: gera uma transferãªncia do segmento para mudanã§a de canal pela delimitaã§ã£o de dados de transferãªncia contã­nua de mudanã§a de canal dentre uma pluralidade de partes de dados de transferãªncia contã­nua em unidades mã­nimas quando a recepã§ã£o dos dados de transferãªncia contã­nua for comutada, de acordo com uma sincronizaã§ã£o comum com um outro canal, distribui por unidifusã£o a transferãªncia contã­nua do segmento de mudanã§a de canal, distribui por multidifusã£o a transferãªncia contã­nua do segmento de mudanã§a de canal e gera um meta-arquivo para que um lado de recepã§ã£o receba a transferãªncia contã­nua do segmento de mudanã§a de canal que ã© distribuã­do por unidifusã£o e distribuã­do por multidifusã£o. a presente descriã§ã£o pode ser aplicada em um sistema que distribui conteãºdo ã  maneira de transferãªncia contã­nua.
