Patent abstract
Adaptive control of codebook regeneration in data compression mechanisms. In one implementation, the present invention provides a means controlling the frequency of codebook updates based on expected performance gains resulting from codebook regeneration. The present invention, in one implementation, employs a mechanism that simulates the expected compression performance of a hypothetically, updated codebook. A compression module compares the simulated compression performance to the actual performance of the codebook used to compress the data, and updates the codebook if a threshold condition is satisfied.
