Abstract

A data compression system comprising a transmit side having a first receive interface adapted to receive a first quantity of data from a first channel and a compression controller coupled to the first receive interface, a lossless compression controller, and a bandwidth monitor, the lossy compression controller and the bandwidth monitor coupled to a first transmit interface adapted to transmit a compressed first quantity of data into a second telecommunication channel wherein the bandwidth monitor evaluates the bandwidth of the second telecommunication channel and communicates with the compression controller. A decimation controller is adapted to lossy compress a portion of a second data quantity in the first telecommunication channel in response to a lossy compression control signal communicated by the compression controller to form a reduced second data quantity if the compression controller determines, that the bandwidth second transmission channel is insufficient to carry the first data quantity when compressed.

Dependent claims

A method of compressing data comprising:

receiving, at an input of a first processor included in a transmit side of a data compression system, a first quantity of data from a first telecommunication channel having a known bandwidth;
losslessly compressing the first quantity of data using a lossless compression algorithm and the first processor to form losslessly compressed data;
evaluating, using the first processor, whether a bandwidth of a second telecommunication channel is sufficient to carry the losslessly compressed data;
receiving at the input a second quantity of data following the first quantity of data in a time order of the data in the first telecommunication channel;
if the bandwidth of the second telecommunication channel is evaluated to be insufficient, then lossy compressing the second quantity of data using a lossy compression algorithm and the first processor, to form first reduced data, and then losslessly compressing the first reduced data using the lossless compression algorithm and the first processor to form first compressed data;
and
if the bandwidth of the second telecommunication channel is evaluated to be sufficient, then losslessly compressing the second quantity of data using the lossless compression algorithm and the first microprocessor to form second compressed data;
and
transmitting the first compressed data and the second compressed data into the second telecommunication channel using a transmission module.

a transmit side comprising:
a first receive interface adapted to receive a first quantity of data from a first telecommunication channel;
and
a compression controller coupled to the first receive interface, to a lossless compression controller, and to a bandwidth monitor, the lossy compression controller and the bandwidth monitor coupled to a first transmit interface adapted to transmit a compressed first quantity of data into a second telecommunication channel;
