COLLABORATIVE RECORDING COMPRESSION TECHNOLOGY USED IN CVRS |
摘要 |
A data compression reduces redundancy over time using information from other frames and among different viewers. A personal compressed copy of content includes an array of keys, and encrypted copy of the content and a codebook. The codebook, which is not a copy of the content may be stored in shared memory. |

1. A method comprising:
A) providing a collaborative cloud storage system comprising:
i) a cloud storage server comprising a network interface process for receiving into an associated network accessible memory data associated with a plurality of content objects, andii) a plurality of viewer device processes operably coupled over a network to the cloud storage server and the network accessible memory, each of the plurality of viewer device processes having access to at least one channel of content objects; B) deriving a key array from user-defined indicia from one of the viewer device process and storing the key array and an encrypted personal copy of content object in a private memory associated uniquely with the viewer device process for storing, C) generating a codebook useful in decrypting personal copy of the content object of the viewer device process and storing in a shared memory space. |
