ABSTRACT
This paper proposes Hierarchical Error-Correcting Codes (H-ECC) for robust multi-resolution semantic map streaming, leveraging unequal error protection to maintain semantic integrity under bandwidth constraints and channel errors.

Key findings
H-ECC achieves up to 40% bandwidth reduction compared to uniform error protection.
The framework combines Reed-Solomon codes for base layer protection with convolutional coding for enhancement layers.
A comprehensive experimental protocol is presented, including baseline comparisons and real-world deployment scenarios.
Limitations & open questions
The paper does not discuss the computational complexity of the proposed H-ECC framework.
The real-world deployment scenarios are not fully explored in terms of scalability.
