Abstract

"BAIXA DE UM ARQUIVO DE COMPUTADOR DE UM TRANSMISSOR VIA UM CONJUNTO RECEPTOR/DECODIFICADOR PARA UM COMPUTADOR". O arquivo, ou uma parte dele, é dividido em uma série de R grupos de dados e cada um dos grupos é subdividido em uma série de C blocos de dados. Um grupo de C blocos de redundância é gerada, cada bloco de redundância sendo relacionado àqueles dos blocos de dados nos R grupos por ser uma OR ou NOR exclusiva de modo de bit daqueles blocos de dados. Cada um dos grupos dos blocos de dados e o grupo de blocos de redundância são transmitidos repetidamente do transmissor. No conjunto receptor/decodificador, pelo menos parte dos blocos transmitidos é recebida e fornecida ao computador. O computador é usado para determinar para pelo menos um dos blocos de redundância recebidos, se aquele bloco de redundância e todos exceto um dos seus respectivos blocos de dados foram recebidos e, nesse caso, regenerar o dito um bloco de dados. Os blocos de dados perdidos podem ser regenerados sem esperar por retransmissão."DOWNLOADING A TRANSMITTER COMPUTER FILE VIA A RECEIVER / DECODER SET FOR A COMPUTER". The file, or a part of it, is divided into a series of R groups of data and each group is subdivided into a series of C blocks of data. A group of C blocks of redundancy is generated, each block of redundancy being related to those of the data blocks in the R groups because it is an exclusive OR or NOR of bit mode of those data blocks. Each of the data block groups and the redundancy block group are transmitted repeatedly from the transmitter. In the receiver / decoder set, at least part of the transmitted blocks is received and supplied to the computer. The computer is used to determine for at least one of the received redundancy blocks, whether that redundancy block and all but one of its respective data blocks were received and, in this case, to regenerate said one data block. Lost data blocks can be regenerated without waiting for retransmission.
