| 20140169761 | Scene Detection Using Weighting Function - In one embodiment, a method includes analyzing characteristics of a media program to label parts of the media program with a plurality of labels where parts of the media program that are determined to be substantially similar are labeled with a same label. The method then analyzes different partitionings of a sequence of the labels to determine partitions for the media program based on a weighting function that is configured to weight the different partitionings based on portions created from the partitions in the different partitionings. Then, a partitioning for the media program is outputted based on comparing the different partitionings of the sequence of labels using the weighting function. The outputted partitioning partitions the media program into a set of portions and provides points for insertion of information for a service in the media program. | 06-19-2014 |
| 20150156204 | ACCESSING STORAGE UNITS OF A DISPERSED STORAGE NETWORK - A method begins with a group of storage units of a dispersed storage network (DSN) receiving a common access request. The method continues with each storage unit of the group of storage units interpreting the access request to determine whether the storage unit is an intended recipient of the access request, where storage units of a sub-set of storage units of the group of storage units are intended recipients. The method continues with each storage unit of the sub-set of storage units determining a type of the access request and a level of the access request. When the access request is a read request, the method continues with each storage unit of the sub-set of storage units retrieving each encoded data slice having an identifier of its slice address substantially matching the a given identifier of the level to produce a retrieved set of encoded data slices. | 06-04-2015 |
| 20150193309 | CONFIGURING STORAGE RESOURCES OF A DISPERSED STORAGE NETWORK - A method begins by a processing module of a dispersed storage network (DSN) ascertaining a decode threshold value for dispersed storage error encoding data for storage in storage units of the DSN. The method continues with the processing module determining a total width value for the dispersed storage error encoding based on the decode threshold value, a number of selected sites within the DSN, and a number of selected storage units of the selected sites. The method continues with the processing module determining logical storage slots within the selected storage units based on the total width value, the number of selected, and the number of selected storage units. The method continues with the processing module writing a set of encoded data slices to a total width value of the logical storage slots within at least some of the selected storage units of the selected sites based on a slice-to-slot mapping. | 07-09-2015 |
| 20150220396 | WRITING ENCODED DATA SLICES IN A DISPERSED STORAGE NETWORK - A method for writing a set of encoded data slices to memory of a dispersed storage network (DSN) begins by a processing module identifying an encoded data slice of the set of encoded data slices for a redundant write operation to produce an identified encoded data slice. The method continues with the processing module generating a set of first write requests regarding the set of encoded data slices less the identified encoded data slice and generating a set of second write requests regarding the identified encoded data slice. The method continues with the processing module sending the set of first write requests to storage units of the DSN and sending the set of second write requests to a set of storage units of the DSN, where each storage unit of the set of storage units is sent a corresponding one of the set of second write requests. | 08-06-2015 |
| 20150355960 | MAINTAINING DATA STORAGE IN ACCORDANCE WITH AN ACCESS METRIC - When an access metric regarding an encoded data object exceeds an access threshold, a method begins by a processing module of a dispersed storage network (DSN) retrieving encoded data slices of a first plurality of sets of encoded data slices and recovering the data object utilizing first dispersed storage error encoding parameters. The method continues with the processing module re-encoding the recovered data object using second dispersed storage error encoding parameters to produce a re-encoded data object, where the re-encoded data object includes a second plurality of sets of encoded data slices. The method continues with the processing module outputting the second plurality of sets of encoded data slices to storage units of the DSN for storage therein and sending a message to retrieving devices of the DSN, where the message indicates use of the second plurality of sets of encoded data slices for the data object. | 12-10-2015 |
| 20150355979 | ACCESSING DATA BASED ON A DISPERSED STORAGE NETWORK REBUILDING ISSUE - A method begins by a set of storage units of a dispersed storage network (DSN) storing a plurality of encoded data slices, where each storage unit stores a unique sub-set of encoded data slices. The method continues with each storage unit dispersed storage error encoding at least a recovery threshold number of encoded data slices to produce a local set of encoded recovery data slices. In response to a retrieval request, the method continues with a device identifying a storage unit of an initial recovery number of storage units having a rebuilding issue and determining whether the rebuilding issue is correctable at a DSN level. When the rebuilding issue is correctable at the DSN level the method continues with the device selecting another storage unit to replace the storage unit to produce a recovery number of storage units and sending retrieve requests to the recovery number of storage units. | 12-10-2015 |
| 20150355980 | RELIABLY RECOVERING STORED DATA IN A DISPERSED STORAGE NETWORK - A method begins by storage units of a dispersed storage network (DSN) receiving a retrieval request for a data object, where each storage unit stores a unique group of encoded data slices of the data object and a local set of encoded recovery data slices. The method continues with some storage units sending the unique group of encoded data slices to a requesting computing device and with one storage unit sending an encoded recovery data slice to the requesting computing device. The method continues with the requesting computing device identifying an errant unique group encoded data slice, correcting the errant encoded data slice based on received data slices to produce an updated unique group of encoded data slices, and dispersed storage error decoding the updated unique group of encoded data slices and the unique groups of encoded data slices from other storage units to recover the data object. | 12-10-2015 |
| 20150356305 | SECURE DATA ACCESS IN A DISPERSED STORAGE NETWORK - A method begins by a processing module of a dispersed storage network (DSN) dividing data into a plurality of data units and generating a plurality of encryption keys from a master key associated with the data and a data identifier associated with the data. The method continues with the processing module encrypting the plurality of data units using the plurality of encryption keys to produce a plurality of encrypted data units and sending the plurality of encrypted data units to a first set of storage units of the DSN for storage. The method continues with the processing module encoding the master key to produce a plurality of encoded master key units and sending the plurality of encoded master key units to a second set of storage units of the DSN for storage. | 12-10-2015 |
