An approach for providing feedback based on monitoring of channels at a customer premise is described. A digital signal representing a plurality of channels transported over a media broadcast network is received at a set-top box apparatus. A determination of whether one of the plurality of channels satisfies a predetermined criterion relating to performance of the media broadcast network is performed. A network feedback signal based on the determination is generated, at the set-top box apparatus, for transmission to a network monitoring node of the media broadcast network.
