Abrégé
The invention is directed to an error correction scheme used in a computer system where data is provided from a service to a terminal. The data is dynamically changing, and the user is interested more in a final or current state of the data than in intermediate states. Data is provided in a stream of blocks with sequential "sequence" numbers associated with each block. The invention assumes that the data provider transmits data blocks in order of sequence. The terminal tracks the sequence numbers of incoming blocks. When the terminal finds that one or more blocks have been skipped or are missing, the terminal sends a request to the central source for update data. Unlike prior art systems, which request that the missing block or blocks be re-sent, the present invention requests that the information contained in the missing command be provided, for example the current data at the display area associated with the missing block. The central source maintains the current data state of all display areas, and so sends a data block containing the requested data. In the meantime, the terminal continues to receive and display all received data blocks without waiting for the update request to be filled. This differs from many prior art schemes where display is halted until replacement data is received.
