赤米 (akagome) is a broader term for red rice, which can include Champa rice but also other varieties. 大唐米 specifically refers to the historical Champa rice.
From 大唐 (Daitō, 'Great Tang', referring to China) + 米 (mai, 'rice'), though the rice actually originated from Champa (modern Vietnam). The name reflects the historical route through China.
