A network connection is established between a multimedia viewer at a viewer's premises and a service provider. The viewer requests presentation of a multimedia channel via the multimedia viewer. In response to the request, an available bandwidth of the network connection is determined, as is a bandwidth requirement of the requested multimedia channel. In response to determining the bandwidth requirement is inconsistent with the available bandwidth, the viewer is provided with an indicator that the first multimedia channel is unavailable for presentation by the multimedia receiver. In response to determining the bandwidth requirement is consistent with the available bandwidth, data representing the content of the requested multimedia channel is transmitted to the multimedia receiver for presentation to the viewer.
