Since the requirement is to upload contents like videos, images, logo etc and manage them, I still think it comes under digital asset management and not document management. Plus as per resourcespace site, which I think best suits the requirement, also describes it.ResourceSpace open source digital asset management software is the simple, fast, & free way to organise your digital assets
Sort of, but it is an extremely odd term to use for them. Digital Assets is normally use to mean computers and the like, not files and documents. In any case, it is too general to provide good results. It is purely file and document management that you seek, so no matter how correct digital assets might be it is too broad to be useful. In the way that you are using the term, we could replace the term "filesystem" with "digital asset management system" and you see how confusing that is.
What do you seek that Sharepoint, Alfresco or the filesystem do not provide?
