Image encoding device, image decoding device, and program thereof

An image encoding device 1 of the present disclosure includes: a neighboring pixel non-reference predictor 11 for generating a predicted image by predetermined neighboring pixel non-reference prediction with respect to each pixel signal of an original image of a block unit; a filter processor 12 for performing a low-pass filter process to a prediction signal located at a boundary of a block of the predicted image by using the decoded neighboring signal neighboring to the block of the predicted image; a prediction residual signal generator 55 for generating a prediction residual signal of a block unit using an predicted image of a block unit; an orthogonal transformer 14 for dividing the prediction residual signal of the block unit into block shapes designated in advance. An image decoding device 5 of the present disclosure includes a neighboring pixel non-reference predictor 53, a filter processor 54, and an inverse orthogonal transformer 52, that are corresponding to the image encoding device 1.. ...

Image encoding device, image decoding device, and program thereof

An image encoding device 1 of the present disclosure includes a neighboring pixel non-reference predictor 11 configured to generate a predicted image by a predetermined neighboring pixel non-reference prediction for each pixel signal of an original image in a block unit, a filter processor 12 configured to perform a low-pass filter process on a prediction signal located at a boundary of a block of the predicted image by using a decoded neighboring signal neighboring to the predicted image under a predetermined control, a prediction residual signal generator 55 configured to generate a prediction residual signal of the block unit by using the predicted image, an orthogonal transformer 14 configured to perform an orthogonal transformation process on the prediction residual signal of the block unit under the predetermined control, and an orthogonal transformation selection controller 25 configured to control the filter processor 12 and the orthogonal transformer 14 and generate a predetermined transformation type identification signal. An image decoding device 5 of the present disclosure performs a decoding process based on a transformation type identification signal at the time of the predetermined neighboring pixel non-reference prediction.. ...

Method for encoding and decoding scheme using time stamp

An encoding device performing an encoding process according to an encoding scheme using a cts indicating time at which presentation or reproduction is performed, comprising: an encapsulator that generates a media unit in which one or more access units encoded by the encoding scheme are capsulated, and a transmitter that transmits information indicating an absolute time of an access unit included at a top portion of the media unit, in addition to the media unit, wherein the encapsulator adds a cts relative value to the nth access unit included in the media unit, the cts relative value being a difference between the cts of the nth access unit and the dts of the n+1th access unit.. . ...
