Automatic adjustments for video post-processor based on estimated quality of internet video content

A system, comprising:

• a quality estimation module configured to estimate a visual quality of video content based on data from a decoder module;
• a settings database configured to i) store a plurality of predetermined settings, wherein the plurality of predetermined settings correspond to adjustable settings for video post-processing, ii) select, based on the visual quality, at least one of the predetermined settings stored in the settings database, and iii) output the at least one of the predetermined settings;
• a video post-processor module configured to automatically adjust settings of the video post-processor module based on the at least one of the predetermined settings, wherein the video content is processed based on the settings of the video post-processor module that were automatically adjusted,
• wherein the post-processor module has a plurality of sub-modules to be adjusted based on the at least one of the predetermined settings,
• wherein one of the sub-modules adjusts at least one of blockyness, ringing, mosquito noise, false edges, blurring and loss of colorfulness in the video content, and
• wherein the post-processor module automatically adjusts sub-module settings of at least one of the plurality of sub-modules based on the at least one of the predetermined settings;
• and
• an estimation module to estimate residual artifacts in output signals from the post-processor module,
• wherein the output signals include the video content after the sub-module settings have been adjusted a first time, and
• wherein the selection module re-selects from at least one of the predetermined settings based on estimates of the residual artifacts to adjust the sub-module settings a second time.

A method, comprising:

• estimating a visual quality of video content based on data from a decoder module;
• storing, in a settings database, a plurality of predetermined settings, wherein the plurality of predetermined settings correspond to adjustable settings for video post-processing;
• selecting, based on the visual quality, at least one of the predetermined settings stored in the settings database;
• outputting the at least one of the predetermined settings;
• automatically adjusting settings of a video post-processor module based on the at least one of the predetermined settings, wherein the video content is processed based on the settings of the video post-processor module that were automatically adjusted;
• determining a quality factor to represent the visual quality of the video content, wherein the data includes metadata information that indicates transmission features for the video content, wherein the metadata information includes a bitrate of the video content, a spatial resolution of the video content, a temporal resolution of the video content and a codec type of the video content;
• estimating the quality factor based on the bitrate and a codec weight divided by the spatial resolution and the temporal resolution;
• weighting the codec type relative to other codec types;
• and
• assigning the codec weight a weight for the codec type relative to the other codec types.
