Video Noise Reduction - Sony DVP-NS300 Training Manual

Video Noise Reduction

Block Noise Reduction (BNR)
BNR reduces dissimilarities (noise) at the edges of blocks (Figure 1-8).
Digital Video Enhancer (DVE)
DVE corrects the frequency response of the video signal and emphasizes picture details, see Figure 1-9. Since
DVE (Digital Video Enhancer) emphasizes BLOCK NOISE, the BNR circuit is used before the DVE .
Block Noise Reduction
The Block Noise Reduction reduces noise at vertical
rising (block) edges caused by the MPEG format.
The picture looks more smother and more natural.
Picture details, even very small once, are not effected.
