Namaste toujour,
thank you for the post.
my compassionate concern for your uncles transition, they can be difficult if one is particularly attached to the being, in my experience.
Buddhist funerals are, generally, predicated more upon cultural considerations than upon Buddhism, per se. for instance.. in Indias' Golden Days, there were a lot of folks living there... so many, that it became the custom to burn the corpses of the transitioned beings. this practice continues to this day in a variety of cultures.
in Tibet, on the other hand, depending on where you live, there isn't a whole lot of wood for building, let alone burning flesh logs. they have a... unique burial rite called a Sky Funeral. basically... and i don't mean to be gross, though i'm trying to speak plainly... the corpse has certain mantras and rites performed by the monks for a certain number of days... generally, 49. after this period of time, or before depending on certain indicators, the corpses are taken to a high mountain and cut into bits to be fed to the raptors and vultures. pretty radical recycling there, don't ya think?
in any event.. then you will have more... shall we say, traditional, sorts of funerals in Thailand and Laos and so forth.
with respect to the Buddhist aspect.. i would tend to suggest that you inquire with your teacher/guru, if you have one and are a member of a Sangha. if not, then i would suggest that you check this link out:
