What does rebroadcasting mean?
Rebroadcasting means sending out a programme, message, or signal a second time. It is commonly used when a radio or television station repeats a broadcast, when an event is carried by another channel, or when a communication system retransmits a received signal. The action may involve the same material reaching a new audience, being shown at a later time, or being relayed through different equipment. In journalism and broadcasting, rebroadcasting can be useful for extending access to important information, such as a news bulletin, concert, emergency announcement, or sporting event. The word is related to broadcast, but the prefix re- specifically indicates repetition. Although “rebroadcast” is the more usual form when naming the action as a general concept, “rebroadcasting” is commonly used in descriptions of repeated transmissions and communications procedures.
To broadcast a programme, message, or signal again.
"The station plans to rebroadcast the documentary later this week."
Often used for repeated transmission on another channel or at another time.
To receive and transmit a signal again, especially in radio or telecommunications.
"The relay station rebroadcast the signal across the valley."
This technical use is common in communications engineering and emergency radio procedures.
A rebroadcast sends a message into the world again, extending the reach of one original transmission.

Etymology of rebroadcasting
The word is formed from the prefix re-, meaning again, and broadcast, which combines broad and cast. The root broadcast developed in the early 20th century for the transmission of radio programmes, and its meaning later expanded to television and other forms of communication. Rebroadcasting uses re- to indicate that a broadcast or signal is being sent again. The same broadcast root also underlies broadcaster.
