Abstract: Systems and methods are disclosed for constructing video image frames including transparency information. Certain embodiments provide for accessing a first frame of digital data associated with a pixel of an image representation, the frame comprising a set of transparency data bits, a set of red data bits, a set of green data bits, and a set of blue data bits. A second frame is constructed comprising a single transparency data bit, a reduced set of red data bits, the set of green data bits; and the set of blue data bits, wherein the second frame is provided to a destination device.

Abstract: In some implementations a method includes receiving a first request for a first ultrasonic audio signature from a first computing device. The method also includes transmitting first data indicative of the first ultrasonic audio signature to the first computing device. The method further includes receiving audio data from a second computing device. The method further includes determining that the audio data is indicative of the first ultrasonic audio signature. The method further includes transmitting, to one or more of the first computing device or the second computing device, a message indicating that the first computing device is in proximity to the second computing device.
