Abstract: A polarizing waveguide plate includes a pair of spaced transparent plates that define a gap therebetween. Disposed within the gap is a composite material formed of a mixture of polymer mater and liquid crystal material. Positioned proximate to one edge of the gap is an edge light, while a reflector/converter is positioned proximate to another edge of the gap. During operation, unpolarized light is emitted from the edge light and is received within the gap. As such, a portion of the light polarized in a first direction is permitted to exit the waveguide, while the remaining portion of the light that is polarized in a second direction, orthogonal to the first direction, is converted by the converter/reflector so that its polarization is also in the first direction. As such, substantially all of the unpolarized light from the edge light is emitted by the polarizing waveguide plate as polarized light.

Abstract: Systems and techniques for testing audio-video synchronization using one or more timestamps are presented. On a media sender end, a media stream with a video stream and an audio stream is generated. A matrix barcode timestamp is added onto a video frame of the video stream at a particular time. Furthermore, a tone timestamp is embedded into the audio stream at the particular time. Additionally, on a media receiver end, a modified media stream is received. For example, the video stream with the matrix barcode timestamp at the particular time and the audio stream with the tone timestamp at the particular time are received. The matrix barcode timestamp is decoded to determine a first time value and the tone timestamp is decoded to determine a second time value. The first time value is compared with the second time value to determine synchronization of the video stream and the audio stream.
