Signal Processing

Data Acquisition and Preparation.

Signal Processing Path - Acquire, Transmit, Process

voice INTER connect offers services around the whole transmission path of audio and video data.

Acquire

Audio

  • Analogue and digital microphone signals in  Mikrofonsignale in highest quality
  • Mulit-channel microphone array for spatial filtering and preparation of beamforming or source localisation

Video

  • Image acquisition in different spectrums
  • Recording in HDR format
  • Support of ethernet-based cameras

Transmit

Audio

  • Own audio / video / data bus, 2-wire, fully flexible
  • Embedded audio / video streaming
  • Audio compression (MP3, G.726, G.728, G.722.1)

Video

  • Video support for ethernet in real time
  • Video compression (H264, MJPEG)

Process

Audio

  • Beamforming (BF) with microphone arrays
  • Acoustic source localisation (ASL)
  • Acoustic echo cancellation (AEC) plus residual echo cancellation, according to ITU-T G.167, VDA-compliant
  • Noise reduction (NR)
  • Voice activity detection (VAD)
  • Audio quality enhancement (EQ, Compressor, Gate)

Video

  • Video Quality Enhancement (Image optimisation - e.g. HDR, NR, WB, EQ)
  • Object detection and person recognition
  • Embedded video codecs (H264, MJPEG)
