Multimedia - Interaktive Studienpläne der TU Ilmenau

MMStandards:

Educational Objectives:

To understand the process of standardisation and how to read major standards for media formats.

In the end the students should be prepared both for participation in a standards committee and to implement a media format standard from the description in the standards document.

Selection of Topics:

Introduction to standardisation of multimedia content, i.e. mainly standardisation of speech, high quality audio, picture and video information including standards for metadata and systems aspect.

The lecture starts with examples from standardisation and continues with
the process of standardisation of media formats mainly in ITU and ISO/IEC organisations.

The lecture series does contain information about all the major standards series in media and at least one more detailed example (including introduction to the technology and bit stream details) for each major area of media standards, i.e. speech, audio, pictures, video, systems, metadata.

Audio Coding

Educational Objectives:

After attending the lecture and solving the homework assignments, the students should be able to have enough basic understanding of high quality audio coding to implement encoders and decoders or participate in ongoing research in the area.

Selection of Topics:

In depth introduction into coding of high quality audio signals. The lecture series comprises of three major parts:

- First, an introduction into the main algorithms used in high quality audio coding (filterbank, psychoacoustic model, quantization and coding)

- Second, an introduction into some of the most used formats for high quality audio coding with an emphasis on the MPEG Audio standards (MPEG-1 including MP3, MPEG-2 including AAC, MPEG-4 including HeAAC)

- Third, current research topics and specialized audio coding formats like lossless coding, very low delay coding, parametric coding etc.
