Audio-visual and multimedia content is becoming omnipresent nowadays, with applications such as video streaming, video on demand, and social media. This evolution is also made possible by ever more powerful devices, including smartphones and tablets, and better network connectivity. To enable the efficient handling of this multimedia content, effective compression methods are needed.

In this lecture, we will review basic theoretical concepts of coding theory, including source coding, transform coding, predictive coding and quantization. In a second stage, we will see how these tools are used in the JPEG image coding standard.
