In an access network (ACCESS NETWORK) wherein channels (TV1, TV2)
of a distributive interactive service are broadcasted, the user terminals (UT1,
UT2, UT3) send first type request information to a broadcasting unit
(BCU2), close to the subscribers, to indicate the requested channels (TV1,
TV6). In case one of the requested channels (TV6) is not available
at the input of this broadcasting unit (BCU2), the latter broadcasting unit
(BCU2) generates second type request information indicative for the unavailable
requested channel (TV6) and sends this second type request information to
a more central broadcasting unit (BCU1). Thus, a broadcasting unit (BCU2)
close to the subscribers upon request of one of the subscribers either broadcasts
a requested channel (TV1) to the subscribers or requests a more central
broadcasting unit (BCU1) to be provided with the requested channel (TV6).
