Abstract

Digital content can be broadcast in a sideband of an analog broadcast channel using multiple digital in-band on-channel (IBOC) transceivers connected in a mesh configuration to form an IBOC mesh network. The digital IBOC transceivers are positioned at various geographic locations, so that unlike traditional “HD” radio broadcasts, the IBOC broadcast transmission is spread out over a wide area, using multiple low power digital IBOC transceivers rather than being broadcast from the same location as the analog signal. An edge transceiver can limit IBOC transmission power of the IBOC transceivers to a desired portion of the power used to broadcast the analog signal. The edge server can make this determination based on measurements taken at the geographically distributed digital IBOC transceivers. The IBOC mesh network provides bi-directional communication between a mesh transceiver and a user device, and can be used to deliver user feedback.
