When underflow occurs in units of groups, the underflow is suitably processed. A video image encoding device includes: a group determination unit to determine a group to which each of a plurality of blocks belongs; an addition unit to add, to an output stream, information about the group to which each of the plurality of blocks belongs; a time determination unit to calculate a display time for each of the groups adding the display time to the output stream; an encode amount control unit to control an encode amount such that data, which are used to decode all of the blocks included in one of the groups, arrive at a receiving buffer of a decoding device by a time expressed by the display time when the data are transmitted to the decoding device at a predetermined transmission rate; and an information amount control unit to implement control such that first data in the following picture do not arrive on the receiving buffer of the decoding device by the display time when the data necessary to decode all of the blocks included in one of the groups does not arrive on the receiving buffer of the decoding device by the display time. |
