Abstract: A system and method for managing public and private information displayed on a user's computer screen by hiding the private information and displaying the public information to others on a secondary display. In one embodiment, a user may select an area of the user's computer screen to be viewed by an audience on the secondary display. The selected area is then copied to a separate location. The separate location is then rendered to the secondary display to be viewed by the audience. The secondary display only contains public information from the user's computer display.

Abstract: A real-time media driver for scheduling and mixing media in a multimedia environment. Implemented to operate in conjunction with a non-real-time operating system, the real-time media driver comprises a wave driver which controls a predominant percentage of the operations of the media hardware device and a mini-device driver which is software provided by the vendor of the media hardware device to support functions unique to the particular media hardware device. Furthermore, the real-time media driver comprises a media scheduler which (i) synchronizes multiple media streams prior to being input into a mixing/splitting device of the media scheduler; (ii) allows reconfiguration of attributes of media streams without loss of content prior to and after operations by the mixing/splitting device; and (iii) appropriately mixes media to produce multi-channel media according to a certain "prioritized sharing" policies.
