In case anyone cares, the announcers speech and some of the text are *NOT* in Spanish!
In the Valencia region they speak their version of
Catalan (from the region around Barcelona), which some call
Valencian.
Catalan is *NOT* a derivative or dialect from "Spanish" (which is more properly called Castilian, for the region in Spain where it originates). Catalan is a Romance Language, and hence a direct descendant from Latin (just like Spanish, French, Italian, Portuguese, etc). In this sense, "Spanish" (Castilian) and Catalan are siblings.
Although most Catalan speakers have learned Spanish, a native speaker from either language would have difficulty understanding the other without significant formal training. However, in writing either language is relatively easy to understand for the speaker of the other.
