This situation of streaming QR code data transmission is similar to the "Binary Erasure Channel (BEC)," which is a communication model. In this model, the sender transmits binary data (0 or 1), and the receiver has a certain probability of not receiving some data bits, which are marked as "erased" or "lost." In other words, the receiver knows which bits are lost but does not know their specific values. This model is used to study and design coding techniques that can effectively transmit information even in cases of data loss.
Scientists have already achieved very mature research results on how to efficiently transmit data in BEC, one of which is using "Fountain Codes." Fountain Codes are a type of error-correcting code that can effectively transmit information even in the case of data loss. This project uses Luby Transform coding, which is a type of Fountain Code. The basic principle is to divide the original data into multiple small blocks and then generate an unlimited number of encoded blocks through encoding. The receiver only needs to receive enough encoded blocks (usually slightly more than the original blocks) to reconstruct the original data.
