Data transmitting apparatus and method

A sending method of a sending apparatus, comprising:

• supplying a material to a plurality of audio channels that send an entirety of a music title repeatedly for a certain unit of time;
• supplying digital data for forming an audio information screen associated with an audio channel being sent;
• supplying audio data for downloading, which is compressed in a certain compression format;
• generating a start flag indicating a start position of the music title;
• generating an end flag indicating an end position of the music title;
• inserting the start flag before the music title;
• and
• inserting the end flag after the music title
• multiplexing, by the sending apparatus, the entirety of the music title repeatedly sent using the plurality of audio channels, which is supplied in the supplying the material step, the digital data for forming the audio information screen associated with the audio channel being sent, which is supplied in the supplying the digital data step, and the audio data for downloading supplied in the supplying the audio data step;
• and
• sending the multiplexed data.

A sending control apparatus, comprising:

• a plurality of audio channel material supplying means for supplying a material to a plurality of audio channels that send an entirety of a music title repeatedly for a certain unit of time;
• data supplying means for supplying digital data for forming an audio information screen associated with an audio channel being sent;
• audio-data-for-downloading supplying means for supplying audio data for downloading, which is compressed in a certain compression format;
• means for generating a start flag indicating a start position of the music title and for generating an end flag indicating an end position of the music title;
• means for inserting the start flag before the music title and for inserting the end flag after the music title;
• and
• multiplexing means for multiplexing the entirety of the music title repeatedly sent using the plurality of audio channels, the digital data for forming the audio information screen associated with the audio channel being sent, and the audio data for downloading,
• wherein, in the plurality of audio channels, a same music material is repeatedly sent in a program within a certain time zone, and the audio data for downloading corresponding to the same music material is sent in the program, whereby a music material to be sent in the plurality of audio channels and the audio data for downloading are associated with each other.
