Abstract

sistema de comunicação, aparelho de comunicação, método de comunicação e programa de computador. conteúdo é transmitido em uma faixa de uso apropriada para um usuário enquanto o número de dispositivos que transmitem conteúdo simultaneamente for limitado. um dispositivo de uso de conteúdo transmite periodicamente, por meio de um comando, um id de chave que corresponde a uma chave de troca. um dispositivo de provisão de conteúdo mantém a chave de troca correspondente apenas enquanto o id de chave puder ser recebido em cada período de recepção especificado. o dispositivo de provisão de conteúdo descarta a chave correspondente quando o id de chave não puder mais ser periodicamente recebido. posteriormente, quando um comando que inclui o id de chave for recebido, uma resposta que inclui informação que indica que a chave de troca é inválida é retornada.
