Abstract

Egy számítógépfájlt egy transzmitterről egy vevő és dekódőlóberendezésen keresztül egy számítógépre letöltő eljárás, amelyneksőrán a fájlt vagy annak egy részét R számú adatcsőpőrtból állósőrőzattá ősztják fel, majd minden egyes adatcsőpőrtőt tővább bőntanakC számú adatblőkk-sőrőzatra, ezt követően C számú redűndanciablőkk-csőpőrtőt állítanak elő, melyek mindegyike az R számú csőpőrtban lévőegyes adatblőkkhőz tartőzik őly módőn, hőgy az említett adatblőkkőkbitenkénti KIZÇRŃLAGOS VAGY vagy NEM-VAGY lőgikai műveleti eredménye,minden egyes adatblőkkcsőpőrtőt és redűndanciablőkk-csőpőrtőt azadóvevővel elküldenek, és az elküldött adatblőkkők legalább némelyikéta vevő és dekódőló berendezéssel veszik, a vett adatblőkkőkat a vevőés dekódőló berendezéstől a számítógéphez tővábbítják, és aszámítógéppel a vett redűndanciablőkkők közül legalább egy alapjánmeghatárőzzák, hőgy a redűndanciablőkk és a hőzzátartőzó adatblőkkkivételével az összes többi adatblőkk megérkezett-e és amennyibenigen, úgy az említett egy adatblőkkőt regenerálják őly módőn, hőgy aredűndanciablőkkőn és a hőzzá tartőzó vett adatblőkkőn bitenkéntiKIZÇRŃLAGOS VAGY vagy NEM-VAGY lőgikai műveletet hajtanak végre. ŕA process of downloading a computer file from a transmitter to a computer through a receiver and decoding device, during which the file or a part of it is broken down into a block consisting of data blocks R, then each data block is further divided into blocks C, and then a block of redundancy blocks C is produced, which all of them belong to the individual data blocks in the pipe port number R in such a way that the logical operation result of the EXCLUSIVE OR or NOT-OR operation for each of the mentioned data block bits, each data block pipe port and redundancy block pipe port are sent with a transmitter and receiver, and at least some of the data blocks sent are received by receiving and decoding equipment, the received data blocks stones it is transmitted from the receiving and decoding equipment to the computer, and the computer determines, based on at least one of the received redundancy blocks, whether all other data blocks have arrived, excluding the redundancy blocks and the heat-related data blocks, and if so, the mentioned one data block is regenerated in this way bitwise logical OR or NOT-OR operations are performed on received data blocks. ŕ
