Transmitting device, receiving device, communication device, programs, transmission method, and receiving method for wireless communication of continuous data in the form of packets. A transmitting device includes a data receiving unit that receives continuous data from a network, the continuous data including actual data and null data; a packetizing unit that deletes at least a part of the null data from the continuous data to generate a packet for wireless communication; a transmitting unit that modulates the packet into a radio carrier wave and wirelessly transmits the resulting packet; and a control unit that causes the transmitting unit to stop transmission of the radio carrier wave during at least a part of a time period in which no such packet is transmitted wirelessly.
