    摘要: A system, a device, a method, a program, and a recording medium with the program recorded thereon, which enable transmitted videos to be reproduced in real time without delay and the reproducibility of videos to be improved are provided. In addition, a system, a device, a method, a program, and a recording medium with the program recorded thereon, which allow states including a degraded communication state to be recognized in a real time manner without delay. A video communication method includes dividing each of a plurality of still image frames of a video including the plurality of still image frames into a plurality of blocks, encoding the plurality of blocks individually on a per block basis, and transmitting an encoded block obtained by encoding a block of the plurality of blocks by a connectionless communication scheme, and reconstructing, for each of the plurality of still image frames, a still image frame by allocating, at a corresponding position, a decoded block generated by decoding the encoded block of one said still image frame, the encoded block being received in an encoded block reception period corresponding to the one still image frame, in which the encoded block reception period is a period from a current frame start time to a time at which a certain time has elapsed, the certain time being obtained by adding a margin time to an expected time for receiving all encoded blocks of one frame.
