Abstract: A data processing apparatus at a transmitter end has an output interface and a display controller. The output interface packs a compressed display data into an output bitstream, and outputs the output bitstream via a display interface. The display controller refers to a compression characteristic of the compressed display data to configure a transmission setting of the output interface over the display interface (e.g., number of data lines, operating frequency of each data line, and/or behavior in the blanking period). A data processing apparatus at a receiver end has an input interface and a controller. The input interface receives an input bitstream via a display interface, and un-packs the input bitstream into a compressed display data that is transmitted over the display interface. The controller configures a reception setting of the input interface over the display interface in response to a compression characteristic of the compressed display data.

Abstract: A method and apparatus for applying DF processing and SAO processing to reconstructed video data are disclosed. The DF processing is applied to a current access element of reconstructed video data to generate DF output data and the deblocking status is determined while applying the DF processing. Status-dependent SAO processing is applied to one or more pixels of the DF output data according to the deblocking status. The status-dependent SAO processing comprises SAO processing, partial SAO processing, and no SAO processing. The SAO starting time for SAO processing is between the DF-output starting time and ending time for the current block. The DF starting time of a next block can be earlier than the SAO ending time of the current block by a period oft, where t is smaller than time difference between the DF-output starting time and the DF starting time of the next block.

Abstract: A method of operating an imaging apparatus includes generating combined sensor settings for a plurality of image sensors by an image signal processor (ISP), and transmitting the combined sensor settings from the ISP in a single operation. The ISP includes a single software flow control for the plurality of image sensors. The method significantly optimizes CPU usage and reduces power consumption in multi-sensor camera systems. By consolidating multiple software and data control flows into a single, unified process, the system achieves a substantial reduction in computational overhead.
