  • Publication number: 20140098893
    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.

  • Publication number: 20140098114
    Abstract: A data processing apparatus has a compressor and an output interface. The compressor receives an input display data, and generates an output display data according to the input display data. The output interface packs the output display data into an output bitstream, and outputs the output bitstream via a display interface. The compressor adaptively adjusts a compression algorithm applied to the input display data according to at least one sensor input signal. For example, the at least one sensor input signal is generated from at least one of an ambient light sensor, a proximity sensor, a thermal sensor, an accelerometer, a gyroscope, and a receiver of a global navigation satellite system.

  • Publication number: 20140098119
    Abstract: A data processing apparatus has a compressor and an output interface. The compressor generates a compressed display data by compressing a display data according to a compression algorithm. The output interface records indication information in an output bitstream, and outputs the output bitstream via a display interface, wherein the output bitstream is derived from the compressed display data, and the indication information is set in response to the compression algorithm employed by the compressor. Another data processing apparatus has a de-compressor and an input interface. The de-compressor de-compresses a compressed display data derived from an input bitstream. The input interface receives the input bitstream via a display interface, parses indication information included in the input bitstream, and configures the de-compressor to employ a de-compression algorithm as indicated by the indication information.

  • Publication number: 20140092986
    Abstract: A method and apparatus of image data compression and decompression are disclosed. According to an embodiment of the present invention, the compression method partitions the image data into access units and encodes each access unit into a bitstream according to a target bit budget. Each access unit is encoded using first data compression to generate a first bitstream and the residual data is further encoded using second data compression to generate a second bitstream if the first bitstream is smaller than the target bit budget. In one example, the second data compression comprises bit plane coding applied to bit plane-ordered data, wherein the bit plane-ordered data is generated by scanning from a most significant bit to a least significant bit of the residual data in a bit plane-wise order. The decompression method comprises steps to recover reconstructed data from the first and second bitstreams.
