Method, apparatus, and system for transmitting information

A system for transmitting audio content comprising:

• an information transmission apparatus;
• and
• a plurality of audio playing apparatuses;
• wherein the information transmission apparatus comprises at least one first processor programmed to perform acts of:
• receiving destination information designating the plurality of audio playing apparatuses as recipients of audio content,
• concurrently transmitting over a wired local area network, to the plurality of audio playing apparatuses designated in the destination information, at least one packet comprising:
• identification information for at least one of the plurality of audio playing apparatuses indicating a recipient of the packet;
• at least a portion of the audio content;
• and
• control information requiring the playing of the audio content by the at least one of the plurality of audio playing apparatuses such that the at least one of the plurality of audio playing apparatuses is instructed to play the audio content concurrently with receiving the audio content,
• receiving a rejection message from an audio playing apparatus of the plurality of audio playing apparatuses, the rejection message identifying that the at least one packet has been rejected by the audio playing apparatus,
• refraining from transmitting further packets to the audio playing apparatus from which the rejection message is received, and
• notifying each of the plurality of audio playing apparatuses to which the transmission of the audio content is completed of an end of transmission of the audio content;
• and
• wherein each of the plurality of audio playing apparatuses comprises at least one second processor programmed to perform acts of:
• receiving the packet including the audio content from the information transmission apparatus,
• processing the audio content storing identification information of the information transmission apparatus transmitting the packet comprising the audio content, said identification information extracted from an information signal sent from the information transmission apparatus, when plurality of audio playing apparatuses receives the information signal, and
• rejecting a request of an electronic apparatus having identification information different from the identification information when the plurality of audio playing apparatuses receives the information signal.

An apparatus for transmitting audio content comprising:

• at least one processor programmed to perform acts of:
• receiving recipient information designating a plurality of audio playing apparatuses as recipients of audio content;
• concurrently transmitting over a wired local area network, to the plurality of audio playing apparatuses designated in the recipient information, at least one packet comprising:
• identification information for at least one of the plurality of audio playing apparatuses indicating a recipient of the packet;
• at least a portion of the audio content;
• and
• control information requiring the playing of the audio content by the at least one of the plurality of audio playing apparatuses designated in the recipient information such that the at least one of the plurality of audio playing apparatuses is instructed to play the audio content concurrently with receiving the audio content;
• receiving a rejection message from an audio playing apparatus of the plurality of audio playing apparatuses, the rejection message identifying that the at least one packet has been rejected by the audio playing apparatus;
• refraining from transmitting further packets to the audio playing apparatus from which the rejection message is received;
• transmitting, to each audio playing apparatus of the plurality of audio playing apparatuses from which no rejection was received, at least one further packet comprising the identification information, at least another portion of the audio content, and the control information;
• and
• notifying each of the plurality of audio playing apparatuses to which the transmission of the audio content is completed of an end of transmission of the audio content.
