Technische Hinweise III - Multimedia- und Netzwerk-Standards

Auf dieser Seite wollen wir zusammentragen welche Standards (und Protokolle) es für die Übertragung und Speicherung von Multimediadaten gibt. Diese Aufstellung kann immer nur Stückwerk sein und den aktuellen Entwicklungen hinterher laufen.

Deshalb können wir keine Garantie für die (Noch-) Gültigkeit einzelner Standards machen, da helfen die Seiten der Standardisierungsgremien CCITT, RFC, ... weiter.

Inhalt

Audio Standards
Video Standards and Codecs
Standards für CAD/CAM Daten
Übertragungs- und Datenstandards für Multimedia Daten
Netzwerkstandards Telefon und Daten
Netzwerkstandard TCP/IP
ISO/OSI Netzwerkstandards

Diese Seite bedarf noch einiger Ergänzungen und Erklärungen ...
... auch und insbesondere welche Vor und Nachteile die einzelnen Standards für die Sicherheit des Nutzers mit sich bringen.
