MAC address A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking tec ...

MPE-based IP Service Offerings


Service Architecture

A complete IP service offering over MPEG-2 TS can be established by organizing MPE streams into one or more IP Platforms carried on a broadcast network by means of the IP/MAC Notification Table mechanism which is also defined in
