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
Scope
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.
