Latest Patents

Philip Graham White holds a patent for a "Method of selecting quantizer values in video compression systems." This patent describes a method for obtaining quantization values for macroblocks in video compression. The process involves estimating the size of a picture based on a sum of all quantized coded coefficients. It assumes a linear relationship between the size of a macroblock and the activity level of the macroblocks. The activity level is defined as the number of coded coefficients in the macroblock before any coefficients are discarded or quantized. The macroblocks are categorized into groups based on their activity level, ensuring that each group contains a similar number of pre-quantization coefficients. An average activity for each group is calculated, and a quantization value is determined based on the linear relationship between bits per macroblock and the average activity, constrained by a predetermined bit rate. This innovative method has the potential to improve video compression efficiency significantly.
