ABSTRACT:
A method enables efficient and coherent sample data storage in a system containing data transmitting and receiving devices. The algorithm is implemented by storing reverse-delta encoded data at a receiver side in a chronologically correct order by a data list and a recovery table, independently of the transmission device. The sender device compares a previously attached timestamp corresponding to each sent data sample to a timestamp attached to an acknowledge signal which it gets back from the receiver device, in order to find out which sample had been correctly received at the receiver side. If the sender does not receive a corresponding pair of timestamp and acknowledge signal until a predefined time interval has elapsed, it automatically resends at least one not acknowledged data sample.
