Abstract:
A video decoding apparatus, a computing system including the same, and a video decoding method. The video decoding apparatus may include an entropy decoder and a video decoder. The entropy decoder may be configured to obtain encoding information of a bitstream of an encoded video from a header of the bitstream, the encoding information of the bitstream including a bit depth of the bitstream, and convert a first quantization parameter of the bitstream into a second quantization parameter when the bit depth of the bitstream is different from a reference bit depth. The video decoder may be configured to decode the bitstream based on the second quantization parameter.
Abstract:
In an application processor having an encoder configured to reduce flicker occurring in a display, the encoder includes a transformer configured to generate first frequency domain coefficients for individual block values of a current frame, a quantizer configured to quantize the first frequency domain coefficients to generate quantized coefficients, and a coefficient calculator configured to generate first adjusting coefficients for reducing the flicker, where the quantizer is configured to adjust the quantization coefficients based on the first adjusting coefficients and output adjusted quantization coefficients.
Abstract:
A data processing system includes a first core configured to decode a first picture and generate decoding history information of the decoded first picture, and a second core configured to modify first motion compensation information included in a second picture based on the decoding history information of the decoded first picture and decode the second picture based on the decoded first picture and the modified first motion compensation information.
Abstract:
A codec according to an exemplary embodiment includes a codec processor which receives a current frame, determines a type of a received current frame, and sets rate control parameters of the current frame, and a bit-rate estimator which allocates total target bits to a first group of picture (GOP) including the current frame, and allocates a target bit to each of frames included in the first GOP based on a determined type of the current frame and set rate control parameters.

Abstract:
A method of individually setting the quantization parameter for each coding unit of a frame in high efficiency video coding (HEVC) is disclosed. The method for setting a quantization parameter for each coding unit in a frame for HEVC encoding includes receiving at least one of partition size information of the coding unit and prediction mode information of the coding unit, performing an adaptive bit allocation operation per each coding unit based on at least one of the unit partition size information of the coding unit and the prediction mode information of the coding unit, and setting a quantization parameter per each coding unit according to the performed adaptive bit allocation operation.
