    摘要: Methods and systems that compensate for display latency when separate speakers are used during video conferencing. A method includes determining whether speakers, which are not controlled by a display, are to be used in connection with a video conferencing session. The method further includes sending, to the display, data that causes the display to generate a predetermined pattern, capturing imagery of the effects of the predetermined pattern shown on the display, calculating a latency of the display based on a difference in a time the data was sent and the imagery of the effects is received, and storing a value of the latency of the display in a device that enables the video conferencing. When the speakers, which are not controlled by the display are selected, are selected, the audio portion of the video conferencing session is redirected to those speakers, but delayed for an amount of time substantially equivalent to the value of the latency of the display. In this way audio and video synchronization may be improved.

    摘要: A system and method for providing a plurality of viewing angles and images on a display. An embodiment comprises a display system where a user has the option of determining the number of images to view and the range of viewable angles for each image. A display system is configured to display a maximum number of images at different viewing angles by interlacing a plurality of images so that each viewing angle shows a selected image. The display system provides a method by which an operator can increase the viewing area of an image by interlacing the same image to more than one viewing angle.

    摘要: Techniques are provided for establishing a videoconference session between participants at different endpoints, where each endpoint includes at least one computing device and one or more displays. A plurality of video streams is received at an endpoint, and each video stream is classified as at least one of a people view and a data view. The classified views are analyzed to determine one or more regions of interest for each of the classified views, where at least one region of interest has a size smaller than a size of the classified view. Synthesized views of at least some of the video streams are generated, wherein the synthesized views include at least one view including a region of interest, and views including the synthesized views are rendered at one or more displays of an endpoint device.

    摘要: A system and method for alerting participants in a videoconference that one or more participants are improperly framed by the videoconference camera is provided. An embodiment comprises a temporary self-view picture-in-picture image appearing when the number of faces detected by the videoconference camera changes. A face detection algorithm is used to determine when the number of faces being detected by the videoconference camera has changed. The self-view picture-in-picture image displays, for a duration of time, a representation of the image being captured by the videoconference camera, allowing participants who are not properly framed by the videoconference camera to adjust their position to that their faces are captured by the videoconference camera.

    摘要: A technique for providing device virtualization in an MS-DOS based operating environment, using an interrupt request (e.g., a non-maskable interrupt), is described. The technique includes executing an application on a processor within the MS-DOS based operating environment and, when the application attempts to address the device to be emulated, causing a processor interrupt to occur. In response to the interrupt, the processor executes code representing the virtualization of a device. The code for servicing the interrupt and emulating the device are written in protected-mode code, stored in the extended memory area, and made available by making appropriate entries into the interrupt descriptor tables (IDTs) for the protected-mode contexts which exist for the native protected-mode operating systems and for the DOS extender. The entries made into the IDT for the protected-mode context established for the DOS extender are accomplished by intercepting communications between the DOS extender and the virtual control program interface (VCPI) and patching the DOS extender's IDT with the vectors to the stored emulation code.
