what is the usage of dvb triplet in Settop box?

I am seeing that the way to identify the service is through DVB triplet. How DVB triplet is formed, and how it guarantees to be unique?

Solution

  • According TS 102 539, a DVB Triplet is composed of:

    1. Original Network Id
    2. Transport Stream Id
    3. Service Id

    This triplet is unique and allows to fully identify a service because:

    • 2 programs will have different S-ID within a TS
    • 2 TS will have different TS-ID within a Network
    • Each Network has his unique ON-ID provided by DVB.
