i don't know if this is the right section to post this... but i guess it's multimedia.

i want to run an ad while playing a video on tv... the tv supports usb input by the way.
to be clear... kita mu anang sa ayala na while ga-play ug salida, naay mga ads na mag-stroll sa bottom sa screen? just like that.
i know that's a specific software used to create/manipulate the output.... kabalo mo unsa? thanks.
