Techniques are disclosed for communicating to remote devices information about change events related to changes in access to an enterprise system. A device access management system may facilitate communication about a change event to the remote devices. Information about a change event may be stored in a change event object based on the type of change event (e.g., a policy change, an application change, and a settings change). A change event queue may persistently store information corresponding to change events. One or more computing nodes may be scheduled to execute an action process for each change event based on the type of the change event. A computing node may communicate information (e.g., an instruction to implement adjust access) about a change event to remote devices. A change event may persist on the queue until all remote devices are notified about the change event.

Low resolution information streams are combined in a broadcast carrier and broadcast along with full resolution information streams down a television broadcast network. The low resolution streams may be decoded and displayed in mosaic display with multiple images from separate low resolution streams simultaneously displayed. When a user selects a particular channel to be displayed, a low resolution stream associated with the selected channel is displayed (video and audio) while the full resolution stream is processed for display. Once the full resolution stream is available for display, it replaces the low resolution stream. The user perceives a much lower channel change time by viewing the low resolution stream during the channel change delay. The low resolution stream may also be provided directly to a portable media player (PMP) in a low resolution format required for display by the PMP.

The subject authentication scheme encompasses a large family of authentication systems which may be built over existing transmission systems. By superimposing a carefully designed secret modulation on the waveforms, authentication is added to the signal without requiring additional bandwidth. The authentication information (tag signal) is sent concurrently with data (message signal). The authentication is designed to be stealthy to the uninformed user, robust to interference, and secure for identity verification. The tradeoffs between these three goals are identified and analyzed. The use of the authentication for channel estimation is also considered, and improved bit errors are demonstrated for time-varying channels. With a long enough authentication code word an authentication system is achieved with very slight data degradation. Additionally, by treating the authentication tag as a sequence of pilot symbols, the data recovery may be improved by the aware receiver.
