Technology - Audio-Visual Coding 1 - MPEG 1 and MP3
We discuss MPEG-1 and MPEG-2 audio compression (coding) and major non-MPEG audio coding systems including Real Audio, Windows Media and Vorbis. A detailed explanation of the internal mechanism of MP3 (MPEG-1 Audio Layer III) compression serves as a basis for understanding MP3pro and all other perceptual audio codecs, including Advanced Audio Coding (AAC).

Technology - Audio-Visual Coding 2 - MPEG 2 AAC and Video
We discuss Advanced Audio Coding and how it improves on MP3. We explain enhancements to both AAC including Spectral Band Replication, Parametric Stereo and Scalable Lossless Coding. We discuss HILN parametric audio coding and voice compression algorithms including CELP. We also explain the process of MPEG-2 video compression, which is the basis of almost all digital television systems.

Technology - Audio-Visual Coding 3 - MPEG 4 Video and VRML
We explain how Advanced Video Coding (AVC/H.264) improves on MPEG-2 video compression. The MPEG-4 standards are of unprecedented scope, including animation, synthetic sound and video, VRML interactivity and Java. We introduce these technologies and discuss how they can be used together to provide services and communication systems far beyond the modes we are familiar with today. We also discuss the MPEG-7 metadata and MPEG-21 digital rights management standards.

Technology - Data 1- Introduction and Frame Relay
Frame Relay predates ATM and is widely used for carrying a mixture of traffic types, including packet- and circuit-switched data, to customer sites and within WANs. We discuss Frame Relay's Quality of Service (QoS) with Permanent Virtual Circuits (PVC), Committed Information Rate (CIR) and Switched Virtual Circuits (SVC). Frame Relay's generally higher efficiency than ATM is discussed in the context of the move towards MPLS and TCP/IP backbone networks.
