Abstract: A computer-implemented authentication protocol is used to subvert man-in-the-middle-type attacks on communications between software components that are permitted to interoperate within a processing environment, such as a media processing environment, pursuant to one or more licenses. In one exemplary scenario, a particular application transmits to a particular media processing component (“MPC”), among other things, a cryptographically protected message including a reference to a process in which the application is running and/or a GUID that the application used to invoke the MPC. If the received process and/or GUID are verified, it is possible for in-the-clear communication to occur between the application and the MPC without man-in-the-middle subversion.

Abstract: Example embodiments of the present disclosure provide techniques for multiple audio device capture and playback during a remote desktop session. A custom device manager may instantiate proxy audio input and output devices on the server corresponding to each real device on the client computer. The proxy devices may redirect their respective audio input and output data to the physical device on the client. In an embodiment, multiple audio devices may be instantiated during a remote session, and multiple independent audio streams may be redirected to the selected device on the client computer.

Abstract: Described herein are one or more implementations offering a centralized (e.g., single-point) user-interface, where a user may manipulate audio properties (e.g., volume level) for one or more audio submixes produced by each of multiple active operating-system processes.

Abstract: A volume control may be provided with some integrated graphical indication of the presence and/or level of an audio signal that it controls. For example, a slider-type volume control may be provided with a signal meter within the slider itself. A volume control may be provided with a mechanism for showing the non-mute volume control level of a volume when the volume control is muted. For example, a slider-type volume control may display a ghosted slider tab at the level of volume control in effect before muting while at the same time displaying a regular slider tab at a muted level. A user may be able to glance at a volume control and quickly and intuitively understand aspects of the volume control's state such as the level and condition of the signal that is flowing through or blocked by (if muted) the control.

Abstract: Methods and apparatuses are provided for controlling application software while switching between session in a multi-session computing environment. An apparatus includes memory coupled to switching logic and application program managing logic. The switching logic is configured to selectively switch console control of a computing device between at least two user kernel sessions that are maintained in the memory. The application program managing logic is configured to selectively control at least one application program that is operatively configured within at least one of the user kernel sessions. For example, the application program managing logic can be configured to stop the operation, restart certain application programs, notify application programs about switching events, and/or adjust the playback of audio and/or video signals associated certain application programs.
