We propose a two-level dimmer based on binary distribution matching where a low-rate signal controls the output probability distribution of a high-rate bit sequence. which can be used in region-of-interest (RoI) signaling applications. To reduce the rate loss of the dimmer. we propose the extended multiset-partition distribution matching (EMPDM) algorithm with a novel binary-tree-stru... https://www.roneverhart.com/Doorking-2334-080-VoIP-RS-232-Control-Box-for-1830-Series/
