ABSTRACT:
A system and method for transmitting blocks of compressed data in an ATM network is disclosed. Compressed data blocks representing a movie are labeled prior to transmission with the amount of data in each block and information regarding the compression ratio of each block and the time into the movie at which the block displays. A server in the system first determines the size of the receiver buffer, and then the minimum number of consecutive blocks that would fit in the buffer. It then determines minimum rate in bits per second by dividing the buffer size by the number of blocks, times 8 bits/byte, times the duration of each block in seconds. The server further instructs the receiver to wait before decompressing and displaying data by an amount of time sufficient to receive the amount of data from the first blocks of compressed data that is equal to the amount of data in the largest compressed data block in the file.
