Educational video codec

This paper presents a simple model of a video codec, which is used for educational purposes. The model is based the MPEG-2 video coding standard and is implemented in the Matlab environment, which allows for easy optimization, modification or creation of new compression tools and procedures. The model contains the basic compression tools for video signal processing and allows extensive settings of these tools. These settings give users an opportunity to learn the basic principles of compression and they also provide an overview of the effectiveness of individual tools. The application is designed primarily for video compression with low resolution.
