Abstract
According to one embodiment, a video decoding apparatus decoding a video stream selectively generates one of an intra prediction image and an inter prediction image based on an encoding mode of a decoding object from the video stream and decoded images thereof, generates a residual decoded image based on a quantization parameter of a decoding object from the video stream, generates a decoded image by adding an intra prediction image and an inter prediction image selectively generated, and the residual decoded image, applies deblocking filter process for reducing a block distortion onto the decoded image, extracting at least one of information on a quantization parameter and information on an encoding mode of a decoding object from the video stream, and determining whether or not the filter process is skipped based on extracted information thereof, and selectively skipping the filter process based on a result of the determination.
