Abstract: A content server may receive from a user device a request for a content asset and may send to the playback device a permit for accessing the content asset. The permit may be used by the content server in order to enforce a concurrency restriction, or a number of concurrent playbacks of one or more content assets desired or permitted by the playback device. In response to receiving a request for a content asset segment associated with a content asset, the content server may determine whether the number of permits currently granted to the playback device exceeds the number of desired or permitted accesses by the playback device, or a group of playback devices, to the content asset or one or more content assets. If so, then the content server may discontinue sending to the playback device any further content asset segments associated with that content asset.

Abstract: A memory device having memory cells operates in a normal mode, a first self refresh mode, and a second self refresh mode. The first self refresh mode provides a self refresh operation for retaining data stored in the memory cells without an external command. The time required to return to the normal mode from the first self refresh mode is shorter than a reference time. The second self refresh mode also provides the self refresh operation, but a time required to return to the normal mode from the second self refresh mode is longer than the reference time. The normal mode provides a higher operating voltage to the memory cells than does the second self refresh mode.
