Abstract: A video conference is established between a first video device and a second video device. The first video device captures a first participant's images in the video conference. The first participant's image is also captured as part of the video conference via the second video device (i.e., there are duplicate images of the first participant's image being captured). The first participant's image is detected as being captured by the first video device and the second video device in the video conference. For example, the duplicate images can be determined based on facial recognition. In response to detecting that the first participant's image is being captured by the first video device and the second video device in the video conference, the process automatically forbears from displaying at least one of the first participant's image captured by the first and second video devices.

Abstract: An apparatus and method for improving performance in high-availability systems are disclosed. In accordance with the illustrative embodiment, pages of memory of a primary system that are to be shadowed are initially copied to a backup system's memory, as well as to a cache in the primary system. A duplication manager process maintains the cache in an intelligent manner that significantly reduces the overhead required to keep the backup system in sync with the primary system, as well as the cache size needed to achieve a given level of performance. Advantageously, the duplication manager is executed on a different processor core than the application process executing transactions, further improving performance.
