Course detail

Video Technology and Multimedia

FEKT-MPC-VTMAcad. year: 2025/2026

The course called Video Technology and Multimedia is focused on teaching the general principles of processing of both analog and digital video signals. Attention is paid to technologies of the whole processing chain for capturing, transmission and displaying of digital video signals. There is a detailed description of following items presented to students: principles of colorimetry, basics of optics, principles of optical sensors, displaying principles, digitalization, interfaces for transmission of video signals, image and compression using standard JPEG and MPEG and principles of work with spatial information.

Rules for evaluation and completion of the course

Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT. Up to 30 points are given for work during the semester, up to 70 points are awarded for the final examination.
The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

Lectures are aimed at presenting the methods and technical means for scanning, display, recording, processing and distributin of analog and, in particular, digital image signals.
The graduate is able to:
- explain the representation of color lights in various color spaces and compute color coordinates in color mixing,
- describe the properties and the generation of video signal,
- describe basic distortions of optical lenses,
- explain the priciple of operation in image sensors of different types and different displays,
- explain and apply the tools of image, video and audio source codecs,
- explain principles of image data distribution using digital interfaces,
- process the video signal in the video editing software,
- explain the basic principles of capturing, recording and reproduction of 3D video signals.
