Teachre(s)/Lecturer(s): Dr. Ruwan D. Nawarathna
Credits: 2 Credits
Introduction and overview: Discrete Cosine Transform Coefficient Coding.
Audio Coding: Analogue and digital form: Sample rate, bits/sample, nyquist rate, bits/sample, nyquist rate,
CD audio Compression techniques:- PCM, ADPCM, LPC, GSM/CELP, MP3/AAC. Video: TV Standards: Interlacing vs progressive scan, PAL, NTSC, SECAM Video digitization, Raw Image Representation: RGB, YUV411, YUV422, Indexed color vs true color Image Compression: - GIF, JPEG, Motion JPEG: Video Compression: - Motion estimation - Motion compensation Video Compression Schemes: - H.261, H.263 - MPEG 1, MPEG 2, MPEG 4 Video Adaptation: - Sender-side adaptation, buffering, VBR-CBR conversion. System Streams: MPEG program and transport streams H.221 framing (for ISDN) IP-based transport: - packet loss - TCP vs. UDP Application-level framing - RTP - H.261 as example of payload format -DCCP Audio/Video synchronization -RTCP - MPEG system stream. Signaling: H.323 SIP and SDP RTSP Megaco. OS Issues: Buffering Scheduling. Describing Network Traffic: Traffic patterns Application requirements QoS parameters and descritions. Congestion control and Resource Management: TCP congestion control Real-time traffic congestion control Queue management: - Random Early Detection + other AQM - Explicit Congection Notification (ECN) - Scheduling mechanisms (FQ, WFQ). Enhanced Quality of Service: Intserv Resource reSerVation Protocol (RSVP) Diffserv. IP Multicast: Service Model Layered transmission Multicast congestion control. Digital rights management: Legal issues Watermarking
