Fuente: Wipo "digitalization" Improved techniques and systems for storage, delivery and acquisition of digital assets stored in cloud data storage. Cloud data storage can be provided by a cloud data repository that is capable of storing digital data for various users. A given user can access cloud data storage from any of his/her authorized client devices via a network. A given client device can access not only locally stored digital assets but also remotely stored digital assets from cloud data storage. In one embodiment, downloads of digital assets resident in cloud data storage to client devices can be managed in view of available network performance. As one example, digital assets of differing quality levels can be downloaded in a manner dependent on network performance. As another example, locally stored digital assets of reduced quality can be upgraded (e.g., replaced) by higher quality versions in a manner dependent on network performance.
