Objectives and competences
The objective of this course is for students to be able to demonstrate understanding of digital image and audio processing algorithms and analyse components of audiovisual services.
Content (Syllabus outline)
• Introduction: taxonomy of audiovisual services, requirements of audiovisual services – QoS (bandwidth, delay, jitter, loss).
• Protocol relating to multimedia services: RTP, RTSP, SIP basics, NTP protocol.
• Data compression: lossless compression. Huffman code, audio coding (PCM, G.711), image coding (BMP, GIFF, TIFF), video coding (SDI/HD-SDI).
• Encoders audiovisual and its transport over IP. Introduction to the lossy compression: limitations of the human eye and ear. Codecs based prediction of the waveform (DPCM, ADPCM), vocoders (GSM, G.723.1, G.728, G.729), MPEG-Audio Encoders, HomeCinema, transportation of audio codecs over IP, streaming audio.
