A video server determines a frequency at which various content titles are accessed, and forms and communicates to downstream client devices a first data carousel of metadata about at least some of the various content titles, the metadata about a particular content title included in the data carousel or not according to how frequently the particular content title is accessed. The video server forms and communicates to downstream edge server devices a second data carousel comprising metadata about at least some of the various content titles, the second carousel updated more frequently than the first data carousel.
