DVB Triplets

For European countries and others, Digital Video Broadcast (DVB) triplets are used as transport IDs. The triplet is a combined numerical identifier separated by periods that ensures a broadcast channel displays correctly. There will be multiple DVB triplets for a station and country because they are received from different networks and belong to diverse streams. Networks can be a big cable operator, satellite distribution, or a minor network with its own headend. Each network operator (small, big) can assign the DVB-triplets based on the need.

DVB Triplet Components

A DVB triplet is represented as three id_parts: ONID, TSID, and SID. Each of these parts is represented by a numerical id and a name indicating the type:

• ONID: Original Network Identifier. This indicates the transport ID subsystem. The ONID is a unique number given to service providers to identify a physical broadcast network as either: Satellite (DVB-S), Cable (DVB-C), or Terrestrial network (DVB-T) signal.

• TSID: Transport Stream Identifier. This number identifies streams within the network. There can be many TSIDs within each ONID unique to the service provider.

• SID: Service Identifier. There are several SIDs within each transport stream (TSID). They are unique only within that specific transport stream and contain numbers for a customer to identify a TV channel.
