According to an embodiment, an image coding method is for coding an image including a luminance component and color difference components. The method includes acquiring a reference image; and generating a predicted image by interpolating the luminance component and the color difference components in the reference image according to a motion vector. If a size of a block, which is designated as a unit of the interpolation, is equal to or smaller than a predetermined first threshold value, the generating includes inhibiting a bi-directional prediction, and performing only a uni-directional prediction to generate the predicted image according to the motion vector.

Image coding method, image decoding method, image coding apparatus, and image decoding apparatus

A method of dividing an input image signal into pixel blocks, and performing inter-prediction on the divided pixel blocks. This method includes selecting predicted motion information from a motion information buffer storing motion information in an encoded region, and predicting motion information of an encoding target block by using the predicted motion information. The method further includes acquiring representative motion information from a plurality of items of motion information in an encoded region in accordance with first information indicating a method of selecting the predicted motion information, thereby obtaining only the representative motion information.

Image encoding and decoding method with merge flag and motion vectors

According to one embodiment, there is provided a multiplexing method including: receiving a TS over IP packet from a plurality of encoders which are disposed at physically remote places, or which are disposed in a virtual environment on a cloud computing system where physical locations are unidentifiable; performing multiplexing after compensating for a delay and jitter of a transmission path, based on a timestamp which is stamped on an RTP header of the TS over IP packet; and performing, with respect to a PCR packet, either multiplexing after compensating for the delay and the jitter, based on a time re-generated in a multiplexing apparatus, or multiplexing by generating a PCR packet in the multiplexing apparatus.
