An intelligent switch and method are described herein which help to effectively retransmit a lost packet that is associated with a television broadcast stream to one or more set-top box(es) (STBs). In one embodiment, the intelligent switch functions as follows: (a) receives, from one of the STBs, a request for a retransmission of a lost packet; (b) forwards, to a broadcast television (BTV) server, the request for the retransmission of the lost packet; (c) initiates a suppression period during which if subsequent request(s) for the retransmission of the same lost packet are received from other STB(s) then the subsequent request(s) would not be forwarded to the BTV server; (d) receives, from the BTV server, a retransmitted lost packet which is associated with the request for the retransmission of the lost packet; and (e) sends the retransmitted lost packet to the STB which sent the request for the retransmission of the lost packet and to the other STB(s) which sent the subsequent request(s) for the retransmission of the lost packet.
