  The equitable distribution of resources in a network is a complex process,
considering that not all nodes have the same requirements, and the In-Band
On-Channel (IBOC) hybrid transmission system is no exception. The IBOC system
utilizes a hybrid in-band transmission to simultaneously broadcast analog and
digital audio over the FM band. This article proposes the use of a Max-Min
Fairness (MMF) algorithm, with a strategy to optimize resource allocation for
IBOC FM transmission in a multiservice scenario. Additionally, the MMF
algorithm offers low computational complexity for implementation in low-cost
embedded systems, aiming to achieve fair resource distribution and provide
adequate Quality of Service (QoS) levels for each node in the RF network,
considering channel conditions and traffic types. The article explores a
scenario under saturated traffic conditions to assess the optimization
capabilities of the MMF algorithm under well-defined traffic and channel
conditions. The evaluation process yielded highly favorable results, indicating
that theMMF algorithm can be considered a viable alternative for bandwidth
optimization in digital broadcasting over IBOC on FM with 95% confidence, and
it holds potential for implementation in other digital broadcasting system.
