A system for transmitting digital data representing an original over plural transmission links (101), at least some of which have limited bandwidth, including a digital data source storing digital data representing the original, a digital data receiver receiving data representing the original via one of the plural transmission links having limited bandwidth and a digital transmitter for transmitting the digital data representing the original to the receiver over a transmitting link having a limited bandwidth in plural blocks (76) which are sequentially transmitted at a rate determined by the limited bandwidth, each block being an incomplete collection of data which includes parts of multiple frames (72), receipt of subsequent blocks by the receiver being used to cumulatively improve the quality of the digital data viewed by the receiver. |
