A comprehensive framework is proposed for the diffuse neutrino fluxes attributed to two different physical processes in core collapse of massive stars. In this scheme, models of thermal MeV-scale neutrinos produced at the core of collapsing stars and non-thermal high-energy neutrinos emitted from accelerated cosmic rays interacting with circumstellar material are bridged through features of core-collapse supernovae (progenitor mass and optical properties). The calculated diffuse fluxes are presented with discussion about their detection prospects at neutrino telescopes.
