The VPC-3 provides noise reduction functionality which targets both mosquito noise and block noise associated with digital compression. Mosquito noise reduction reduces noise which often occurs near edges, due to quantization of DCT coefficients. Block artifact reduction detects and adaptively softens block boundaries frequently visible in regions of low variability. In either case, an advanced algorithm ensures that noise reduction is achieved with minimal undesired loss of detail. Automatic detection of block boundaries means that no prior knowledge of video format or block alignment is required. When combined with the Gaussian noise reduction feature of the VPC-1 Deinterlacer IP core, a complete noise reduction suite is provided to address most types of noise.


  • Reduces mosquito noise associated with digital compression
  • Detects and adaptively softens block boundaries frequently visible in regions of low variability
  • Separately controllable levels for both Mosquito Noise Reduction and Block Artifact Reduction
  • Minimizes undesired loss of detail
  • Compatible with both progressive and interlaced sources
