VIDEO PROCESSING WITH DYNAMIC RESOLUTION CHANGES

摘要

Approaches for filtering an incoming video signal to a sub-resolution before encoding by a standard block based encoding algorithm. The selection of the resolution to which the incoming signal is down filtered is determined on the basis of a prediction of the video quality that may be expected at the system output with regard to the complexity or entropy of the signal. The predicted output video quality may be estimated on the basis of the Quantization Parameter of an encoder receiving the input video signal or a filtered video signal. The selection of a new down-filtered resolution may be carried out with regard to one or more thresholds.

主权项

1. One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for processing a video signal, which when executed, cause:
predicting an output video quality based on an analysis of a version of an incoming video signal; comparing the predicted output video quality with a defined video quality threshold; selecting an optimal resolution based on said defined video quality threshold; and filtering said incoming video signal to said optimal resolution.
