157 Xing Distributed Media Architecture: Glossary
MPEG - Motion Picture Experts Group. The international standards for
compression of video and audio. There are actually two standards -
MPEG-1 (ISO/IEC 11172) and MPEG-2 (ISO/IEC 13818). MPEG-1 was
originally designed for delivery of video to consumer devices at
single speed CD-ROM data rates (150kbytes/sec), and is therefore lower
resolution and lower quality than MPEG-2, which was designed for
delivery of broadcast and HDTV quality video. Each MPEG specification
actually has 3 parts which define the video stream, the audio stream
and the video+audio encapsulating transport stream.
TCP-IP - Transmission Control Protocol + Internet Protocol. A
collection of communications protocols (including TCP, IP, UDP, ARP,
IGMP, ICMP, RAP, RIP, SNMP) that are the basis of the Internet and all
Unix networking. Because TCP-IP can support both local and wide area
networking, while Novell's Netware protocols were designed only to
support local area networking, TCP-IP is rapidly become the standard
as well for PC Windows networking through an interface called
"WINSOCK".
HTML+HTTP - Hypertext Markup Language + Hypertext Transport Protocol.
HTML is a page description language and HTTP is a communications
protocol that runs on top of TCP-IP. Combined, HTML+HTTP define the
basis for applications such as Mosaic and Netscape, which are the
primary tools for navigating the Internet's "World Wide Web". HTML
defines the contents of pages which are viewed on the "Web", and HTTP
defines the way an HTML browser talks with an HTML server (refered to
as an HTTPD or Web server). It is important to note that HTML+HTTP
can be used on local area networks and private data networks, and are
rapidly becoming the standard for in-house corporate information
systems which are not necessarily Internet connected.
