Abstract: An apparatus configured to record and process video information includes a memory, display, and a processor in communication with the memory and the display. The memory is configured to store video data. The display is configured to display a preview of the video data. The processor is configured to record the video data at a first frame rate, process the recorded video data via removing one or more frames from the recorded video data, the processed video data having a second frame rate that is lower than the first frame rate, and generate the preview to be displayed by the display based at least in part on the processed video data.

Abstract: The techniques of this disclosure relate to video encoding and include using an inter mode determination for neighboring blocks, rather than the final prediction mode determination for the neighboring block, when determining an inter mode for a current block. In this way, inter mode and intra mode estimation may be separated and performed in different stages of a multi-threaded parallel video encoding implementation. In addition, this disclosure also proposes generating sub-pixel values in a third stage of the multi-threaded parallel video encoding implementation at a frame level, rather than for each macroblock during inter mode estimation process for that macroblock.

Abstract: Methods, systems, and devices are described for processing Visual Light Communication (VLC) signals by identifying a subset of pixel elements likely to receive at least a portion of of detectable light transmitted from one or more VLC light sources, based on a first frame of pixel sample values. One method may include generating a second frame of pixel sample values of VLC signal intensities and limiting processing to the identified subset of the pixel elements.
