Abstract
A system is provided for the storage and decoding of data which may be used to produce an image. A storage device is functionally divided into a number of sections, so that data may be read from certain sections of the device at a time when other sections have not been completely loaded with data. A decoding memory is utilized for the decoding of information which has previously been encoded at an earlier stage, so that the decoded information can then be applied to a utilizing device. The same read address counter is used to address corresponding locations in the storage device and the decoding memory, and the data output from these two addresses is compared to provide decoded data which constitutes the output information, and which is also written back into the corresponding location of the decoding memory, to be employed in the next comparison operation.
