Mesh transceiver for in-band on-channel broadcasting (IBOC) mesh network
First Claim
1. A mesh transceiver for use in an in-band on-channel (IBOC) mesh network including a plurality of mesh transceivers located at a plurality of different physical locations, the mesh transceiver comprising:
- a variable-power IBOC transmitter;
at least a first network interface;
a processor and associated memory coupled to the variable-power IBOC transmitter and the at least a first network interface, the processor and associated memory configured to obtain information related to IBOC transmission power levels of the variable-power IBOC transmitter;
the at least a first network interface configured to;
transmit the information related to the IBOC transmission power levels to an external processing device configured to manage the IBOC transmission power levels;
receive content for IBOC broadcast by the variable-power IBOC transmitter;
receive a power-control signal generated by the external processing device, the power-control signal indicating a particular IBOC power level to be used by the variable-power IBOC transmitter; and
the variable-power IBOC transmitter configured to broadcast the content at the particular IBOC power level.

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.
