Abstract

Systems and methods for providing accelerated transmission of broadcast data, such as financial data and news feeds, over a communication channel using data compression and decompression to provide secure transmission and transparent multiplication of communication bandwidth, as well as reduce the latency associated with data transmission of conventional systems.

Claims

1-24. -24. (canceled)

25. A method comprising:

recognizing a data field type of a data field in a packet;

selecting an encoder associated with the recognized data field type;

compressing the data in the data field with the selected encoder;

broadcasting the compressed data to a plurality of clients, wherein the compressing achieves a compression ratio of over 10;

1; and

utilizing a decompression state machine that comprises a plurality of decompression tables to decompress the compressed data on at least one of the plurality of clients.
