Abstract:

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.

Abstract:

A layered surface is provided that includes a first, second, third and fourth layer. The first layer includes a mixture of cement and acrylic resin. The first layer is further formed from two sub-layers. The first sub layer includes a mixture of cement and acrylic resin and has a ratio of cement to acrylic resin of approximately 10 to 1. The second sub-layer has a mixture of cement and acrylic resin at a ratio of cement to acrylic is greater than that of the first sub-layer. The second layer includes a colorant, the third layer includes an epoxy resin, and the fourth layer includes a wax.
