A collaborative cloud DVR system (ccDVR), which includes a cloud storage system and a plurality of participating DVR client devices, acts collaboratively as a single communal entity in which community members authorize each other to upload, remotely store and download licensed content for time shifted viewing, in a manner which rigorously protects legal rights of the content owners while overcoming the potential physical obstacles of limited bandwidth, power failures, incomplete uploads or downloads of content, limited cloud storage capacity, etc. The collaborative cloud DVR community collaboratively shares bandwidth and cloud storage capacity among a plurality of DVR viewer/users with each owner/user of a DVR client device authorizing his or her individual DVR client device to be utilized by a cloud storage system server and any other owner/user of a DVR client device in the respective service community, and receiving similar permission in return to promote the convenience of cloud storage in an authorized manner. |
