Abstract
A system for processing video data to improve image quality at low data rates comprising an encoder generating an entropy signal representing the relative entropy of the video data and a plurality of filters each receiving the entropy signal and a threshold setting and filtering the video data if the entropy signal is greater than the threshold setting.
Claims19
A system for processing video data to improve image quality at low data rates comprising:
- an encoder operating on a processor and configured for generating an entropy signal representing a relative entropy of the video data;
- and
- a plurality of filters each operating on the processor and configured for receiving the entropy signal and a threshold setting and filtering the video data if the entropy signal is greater than the threshold setting, wherein the filters comprise:
- a variable anti-jitter filter;
- a variable anti-alias filter;
- and
- wherein the threshold settings of the variable jitter filter and the variable alias filter are symmetric.
