A video coding method is a video coding method for coding an image in units of blocks obtained by dividing an image, and in the method a computer performs processing for dividing the image into blocks, acquiring an intra-image prediction mode predicted for each block, and generating, by using a combination pattern based on the intra-image prediction mode of a plurality of blocks adjacent to at least any one block, determining whether or not the plurality of blocks are to be combined, and performing prediction for each combined block when it is determined that the plurality of blocks are to be combined.

A coding method is a coding method executed by a coding apparatus. The coding method includes partitioning a first block having a predetermined size in an original image into a group of second blocks each being a block serving as a unit for coding, by quad tree, ternary tree, or binary tree, and predicting movement for each of the second blocks. The partitioning includes first sub-partitioning and second sub-partitioning, the first sub-partitioning includes partitioning the first block into blocks each having a size selected from sizes determined according to the quad tree, the ternary tree, or the binary tree, and the second sub-partitioning includes further partitioning the blocks each having the selected size to generate the second blocks.

Provided is a transmission device for transmitting and receiving data through a transmission channel. The transmission device includes a transmission circuit unit configured to transmit data to the transmission channel. When an overcurrent caused by a simultaneous transmission of data to the transmission channel is detected during data transmission, the transmission circuit unit increases an output resistance, which is a resistance value for an output to the transmission channel, to an resistance value corresponding to a characteristic of a facility equipment item that transmits data to the transmission channel at the same time as itself.

A computation unit subtracts a prediction image from an input image. An orthogonal transformation unit applies orthogonal transformation to an output of the computation unit. A quantization unit quantizes an output of the orthogonal transformation unit. An encoding unit encodes an output of the quantization unit. A prediction mode determination unit determines a prediction mode from the input image. The prediction mode is different according to types of an I-picture, a P-picture and a B-picture.

In an intra-picture, a predetermined region is set as a normal encoding region, and a region other than the predetermined region is set as a simplified encoding region. In a subsequent picture, the normal encoding region is set as a larger region including a normal encoding region of a previous picture, and a region other than the normal encoding region is set as a simplified encoding region. In each picture, normal encoding is performed on a block of the normal encoding region, and simplified encoding in which a generated code amount and a computation amount are smaller than in the normal encoding is performed on a block of the simplified encoding region.
