DVB-SI | Network_ID


A Network is defined as a “collection of MPEG 2 Transport Stream (TS) multiplexes transmitted on a single delivery system, e.g. All digital channels on a specific cable system.” In the specific case of a terrestrial network, a specific Network_ID is associated with each major transmission point.

Network_IDs are unique within the geographical region defined by the “country_code”. For satellite networks, this is a region spanning many countries. For a cable network, this is a single country. For terrestrial networks, this is a single country also, but it’s important that two adjacent countries NOT have the same block of Network_IDs, hence the concept of colour coding.


Key Fields
"Network_Name" - Name of the Network, e.g. “ACME Cable”
"Network_Country_Code" - Country code where the Network is unique, e.g. North America
"Network_Operator" - Name of company which operates Network, e.g. “ACME Pay-TV, Inc.”
