Definition
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 Type” – satellite, terrestrial or cable
- “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 the company that operates the network, e.g. “ACME Pay-TV, Inc.”
