Abstract
Apparatuses and methods for adjusting coefficients for use in video encoding are described. An example apparatus may include an encoder that may be configured to receive transform coefficients and adjust selected ones of the transform coefficients (e.g. reset the selected ones to zero) based on a comparison with a threshold. The adjusted coefficients may then be quantized, which may result in effectively increasing a QP range of the encoder.
