1. A radio communication system for transmitting voice or music data, comprising:

  • a data supplying source device for supplying the voice or music data, the data supplying source device having a reflector for transmitting a reflected wave signal obtained by modulating a received radio wave based on the data to be transmitted; and

    a data supply destination device for receiving the voice or music data, the data supply destination device having a reflected wave reader for transmitting an unmodulated carrier and for reading a reflected wave signal resulting from modulation of the unmodulated carrier;

    wherein the voice or music data is transmitted in packets to be reproduced on said data supply destination device by reflected wave transmission between the data supplying source device and the data supply destination device; and

    wherein when a data type indicator in the data packet indicates that the data type is voice or music the data supply destination device begins a process of decoding a part of the voice or music data packet without waiting for the voice or music data packet to be operated on by a process of a communication protocol that is at a higher protocol level than the decoding process,wherein when the data type indicator in the data packet indicates that the data type is a content that the data supply destination device is not ready for decoding, the data supply destination device discards the data packet including the content that the data supply destination device is not ready for decoding without waiting transfer to a process of the communication protocol that is at a higher protocol level than the decoding process, andwherein when the data type indicator in the data packet indicates that the data type is command a notification thereof is made to a higher protocol level than the decoding process.
