Goals
Knowledges in compression (coding) of audio and video signals, from the theoretical bases of the usual methods, to various specific applications to audio and video coding. An overview of current main standards is made. Labworks with PCs will illustrate the courses.

Content - Theoretical basis :
o Basic definitions : coders bitrate, complexity and quality
o Architecture of a signal compression system
o Uniform and nonuniform scalar quantization
o Vector quantization, predictive coding, transform coding, entropy coding and perceptual coding - Applications :
o Audio signals coding (speech and music) : from LPC vocoder to CELP, MPEG (MP3 included)…
o Video coding : MPEG… - Standards : ITU-T, ETSI, MPEG…
PrerequisitesSignal processing theory.
Tests Written exam (2h)(E).
