Osaamistavoitteet

The course provides fundamental knowledge about media types, formats and compression technologies used in multimedia communications. After completing the course the student is familiar with the technologies and standards related to multimedia and basic multimedia services. The student knows how to acquire speech, audio, digital images and digital video and how they are compressed and multimedia data manipulated using software tools. The student knows how to set up basic multimedia services (e.g. Video streaming) and can estimate the requirements (bitrate, latency etc.) for multimedia networks. The student is able to select proper tools for non-real time and real time media compression and can estimate requirements for networks for multimedia applications.
