Abstract: Methods, apparatuses, and systems are provided for improving utilization of the satellite communications system through various “deltacasting” techniques for handling content sets (e.g., feeds or websites). Embodiments operate in a client-server context, including a server optimizer, a client optimizer, and, in some embodiments, a pre-positioning client. Within this client-server context, content sets are multicast (e.g., anticipatorily pre-positioned in a local dictionary) to end users of the communications system and are handled at the content set level, according to set-level metadata and/or user preferences. In some embodiments, when locally stored information from the content sets is requested by a user, deltacasting techniques are used to generate fingerprints for use in identifying and exploit multicasting and/or other opportunities for increased utilization of links of the communications system.

Abstract: A system and method can monitor one or more user sessions on a target system in a computing environment. An account managing system can capture a plurality of user session screen captures that are associated with said one or more user sessions on the target system. Furthermore, the account managing system can compare a user session screen capture, which is captured at a time during said one or more user sessions, with one or more user session screen captures that are recorded before the time. Then, the account managing system can record said user session screen capture if the target system is determined to be active at the time when said user session screen capture is captured.
