Abstract: An encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side has an external-output request determining unit that monitors the state of a network. If the network assumes an undesirable state, the request determining unit causes a multiplex output unit to stop multiplexing data. When the network assumes a desirable state, the multiplex unit starts multiplexing the data again.

When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the encoding units stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.
