DVB-SIS (Single Illumination System)

Metadata generation and deterministic DVB-T-megaframe/DVB-T2-MI stream generation from MPEG-2 Transport Stream(s) for a DVB Single Illumination System


The present document describes the Single Illumination System, which allows to deliver Parent Signals for direct reception by consumer receivers and, at the same time, for a deterministic generation of daughter streams for terrestrial retransmission. Parent Signals can be provided to the daughter site via all defined TS-based DVB means – be it satellite, cable or terrestrial. Metadata may be provided as part of the Parent Signal(s) (called “in-band” in the present document). Part of the metadata may also be provided “out-of-band”.

A typical use case is described by the present document and is based on satellite broadcast signals on parent side – be it DVB-S (ETSI EN 300 421), -S2 (ETSI EN 302 307-1) or -S2X signals (ETSI EN 302 307-2) – that are addressing consumer Direct-to-Home (DTH) receivers and terrestrial transmitters on daughter side in parallel. For terrestrial retransmission of the whole or partial content, the DTH signal(s) of MPEG-2 TS format (ISO/IEC 13818-1) from one or several satellites can be used and services and service components can be selected according to terrestrial broadcasters’ needs. Also other non-satellite Parent Signals and out-of-band metadata feeds can be integrated into the preparation of the terrestrial DVB-T2, ETSI EN 302 755, and/or DVB-T, ETSI EN 300 744 signals on daughter site. Single Frequency Networks (SFN) operation of the terrestrial networks driven by the Single Illumination System is enabled.
