Distribiye distribisyon (DTx) se itilize nan plizyè estasyon medyòm-pouvwa (anjeneral dijital) yo kouvri yon zòn emisyon, olye ke yon sèl-wo pouvwa ak plizyè estasyon ba-pouvwa. Eksperyans yo te montre ke sa a ka fè menm ak ATSC si A-VSB yo itilize. Itilize chanèl vityèl yo se yon lòt altènatif, menm si sa ka lakòz kanal la menm parèt plizyè fwa sou yon reseptè (yon fwa pou chak estasyon relè), ak mande pou itilizatè a melodi manyèlman youn nan pi bon (ki chanje akòz kondisyon pwopagasyon radyo. tankou move tan). Sèvi ak rapèl oswa DTx olye fè tout estasyon relè ideyalman parèt kòm yon siyal sèl, men mande pou jeni emisyon enpòtan nan travay byen epi yo pa lakòz destriksyon destriktif nan siyal chak lòt la.

Distributed transmission (DTx) is the use of several medium-power stations (usually digital) to cover a broadcast area, rather than one high-power and several low-power stations. Experiments have shown that this can be done even with ATSC if A-VSB is used. The use of virtual channels is another alternative, though this may cause the same channel to appear multiple times on a receiver (once for each relay station), and requires the user to tune manually to the best one (which changes due to radio propagation conditions like weather). Use of boosters or DTx instead causes all relay stations to ideally appear as a single signal, but requires significant broadcast engineering to work properly and not cause destructive interference to each other's signals.
