A content management resource transmits a received digital data stream in a respective network data channel to one or more subscribers. The content management resource receives an emergency notification control signal, which indicates occurrence of an emergency message. In response to receiving the emergency notification control signal, the content management resource transmits the emergency message in the digital data channel to the one or more subscribers in lieu of transmitting the received digital data stream of content in the data channel to the one or more subscriber. Thus, a subscriber can tune to a particular channel to play back selected content and be apprised, via receipt of the message over the particular channel, of a corresponding condition such as an emergency.
