Patent number: 9185426Abstract: A video receiver is operable to receive three-dimensional (3D) video bitstreams from a video transmitter. The received 3D video bitstreams comprises a plurality of video frames and corresponding coding information. The coding information, for example, block motion vectors, block coding modes, quantization levels, and/or quantized residual data, is extracted for performing frame-rate up-conversion on the received plurality of video frames. The coding information is generated at the video transmitter via entropy decoding on a compressed 3D video from a video feed from, for example, an IP TV network. When an uncompressed 3D video is received, the video receiver is operable to perform frame-rate up-conversion on the received uncompressed 3D video using extracted block motion vectors and associated confidence-consistence measure. When a compressed 3D video is received, the video receiver is configured to perform video decompression on the received compressed 3D video prior to the frame-rate up-conversion.Type: GrantFiled: April 21, 2009Date of Patent: November 10, 2015Assignee: BROADCOM CORPORATIONInventors: Xuemin (Sherman) Chen, Marcus Kellerman

Patent number: 9183779Abstract: The present disclosure is directed to a method and apparatus for estimating ambient light conditions for an OLED display. Embodiments of the method and apparatus use one or more columns of OLEDs in the display to perform two functions: their typical function of emitting light in a display mode, and the additional function of sensing light in a sense mode. To perform the additional sense mode functionality, the one or more columns of OLEDs in the display are temporarily placed into a photovoltaic and/or photoconductive mode. A sensing circuit is used to measure this current produced by the one or more columns of OLEDs while operating in the sense mode and report it back to a controller.
