reading a first subsequent data group from the memory;

calculating a data delta between the first data group and the first subsequent data group;

the codec compressing the data delta;

determining if a compression ratio of the compressed data delta is within a predetermined tolerance threshold,

if the compression ratio is within the predetermined tolerance threshold, transmitting the compressed data delta as a delta data frame across the electronic communication network to the server;

reading a second subsequent data group from the memory; and

repeating the calculating, compressing, and determining steps for the second subsequent data group.

2. The method of claim 1 , including:

if the compression ratio is not within the predetermined tolerance threshold, compressing the first subsequent data group;

transmitting the compressed first subsequent data group as an updated reference frame across the electronic communication network to the server;
