Abstract: A matrix compression/decompression accelerator (MCA) system/method that coordinates lossless data compression (LDC) and lossless data decompression (LDD) transfers between an external data memory (EDM) and a local data memory (LDM) is disclosed. The system implements LDC using a 2D-to-1D transformation of 2D uncompressed data blocks (2DU) within LDM to generate 1D uncompressed data blocks (1DU). The 1DU is then compressed to generate a 1D compressed superblock (CSB) in LDM. This LDM CSB may then be written to EDM with a reduced number of EDM bus cycles. The system implements LDD using decompression of CSB data retrieved from EDM to generate a 1D decompressed data block (1DD) in LDM. A 1D-to-2D transformation is then applied to the LDM 1DD to generate a 2D decompressed data block (2DD) in LDM. This 2DD may then be operated on by a matrix compute engine (MCE) using a variety of function operators.

Abstract: Discussed is an organic light emitting display device including a display panel; a human body detection unit to detect a human body existing in front of the display panel; a human body determination unit to determine whether the human body exists and a location of the human body with respect to the display panel based on detection information from the human body detection unit; a brightness control unit to determine whether to control a brightness of the display panel based on a result of the determination by the human determination unit; and a timing controller to control image data provided to the display panel based on the determination from the brightness control unit. Accordingly, a viewer can view a sufficiently bright image, and energy can be saved and threshold voltage (Vth) difference can be compensated for.

Abstract: A method of sharing a screen of a first device with a second device and a device using the same are provided. The method includes transmitting information on a first screen displayed on the first device to the second device, in a first connection state so that a same screen is displayed by the first device and the second device; switching the first connection state between the first device and the second device into a second connection state; and performing a control so that the first screen displayed on the first device is switched into a second screen so that the first screen displayed is continuously displayed on the second device, when a user input is received in a state in which the first connection state is switched into the second connection state in which an independent screen is displayed by the first device and the second device.

Abstract: Content sharing methods and apparatuses are provided that relate to the field of communications. A method comprises: determining a projection region of a target region on a display region of a first display device relative to at least one eye of a user; and sending related information of the projection region to a second display device. The methods and apparatuses can simplify content sharing steps, improve content sharing efficiency and/or enhance user experience.

Abstract: An image capture accelerator performs accelerated processing of image data. In one embodiment, the image capture accelerator includes accelerator circuitry including a pre-processing engine and a compression engine. The pre-processing engine is configured to perform accelerated processing on received image data, and the compression engine is configured to compress processed image data received from the pre-processing engine. In one embodiment, the image capture accelerator further includes a demultiplexer configured to receive image data captured by an image sensor array implemented within, for example, an image sensor chip. The demultiplexer may output the received image data to an image signal processor when the image data is captured by the image sensor array in a standard capture mode, and may output the received image data to the accelerator circuitry when the image data is captured by the image sensor array in an accelerated capture mode.

Abstract: A digital broadcast transmitter includes a block processor encoding mobile service data at a coding rate of 1/H and first interleaving the encoded mobile service data, wherein H is an integer equal to or greater than 2, a deinterleaver deinterleaving the first-interleaved mobile service data to output a first data group, an interleaver second interleaving the first data group to output a second data group including the mobile service data, a trellis encoding module trellis encoding data of the second data group, and a multiplexer multiplexing the trellis-encoded data with segment synchronization data and field synchronization data, wherein the block processor is concatenated with the trellis encoding module.
