Abstract:
1. A device intended to be positioned upstream of a modulator in a digital service stream broadcasting chain, said device comprising: receiving means for receiving a plurality of transport streams, each said transport stream encapsulating a digital service stream adapted to be broadcast by said modulator, said digital service streams representing the same digital service: extracting means for extracting digital service streams respectively encapsulated in the received transport streams; detecting means for detecting errors at one of a level of the received transport streams and a level of the extracted digital service streams; aligning means for aligning the extracted digital service streams; selecting means for selecting a stream from the aligned digital service streams, according to any errors detected by said detecting means; encapsulating means for encapsulating the selected digital service stream, in order to form a resulting transport stream to be transmitted to said modulator; and transmitting means for transmitting the resulting transport stream to the modulator.
