Audio Containers/Formats: PCM - Pulse Coding Modulation General uncompressed audio. Found on CDs and DVD Audio discs. Produced by Audio digitizers. DVI - Digital Audio/Video Inserter. It is a standard that compresses 16-bit sound data into only 4-bits. http://home.comcast.net/~chris.bagwell/AudioFormats-4.html GSM - Global System for Mobile Communications . It compresses 160 13-bit samples into 260 bits (or 33 bytes), i.e. 1650 bytes/sec (at 8000 samples/sec). It results in very good compression with good quality output but is very costly in terms of performance. http://home.comcast.net/~chris.bagwell/AudioFormats-4.html
LPC - Linear Prediction Coder (Enhanced). It has a has a 2400 bits/s rate. http://home.comcast.net/~chris.bagwell/AudioFormats-4.html Video Formats JPEG - Joint Photographic Experts Group. Is used to compress images. The amount of compression can be determined by the user. H261 - H.261 is a standard video-conferencing codec. It is optimized for low data rates and relatively low motion. http://www.siggraph.org/education/materials/HyperGraph/video/codecs/H261.html PVH - Progressive Video with Hybrid tranformation. Protocols RTP - Rapid Transfer Protocols. FAQ page on RTP http://www.cs.columbia.edu/~hgs/rtp/faq.html#transport AVP - Audio-Video Transport Protocol. Includes audio-based synchronization and prioritized packetization. http://eewww.eng.ohio-state.edu/~zheng/lecture-3-AVP.ppt
