Information transmitting and receiving system, information transmitting device, and information receiving device

An information transmitting device for transmitting information to be displayed by an information receiving device, comprising:

• an information reading section which reads out information recorded in an information recording section;
• an information processing section which divides the information read out from the information recording section by the information reading section into a plurality of information segments, and gives an identifier uniquely for each divided information segment;
• and
• an information transmitting section which repeatedly transmits a bundle of identifiers including the identifier within a first period of time.

An information transmitting device for transmitting information to be displayed by an information receiving device, comprising:

• an information reading section which reads out information recorded in an information recording section;
• an information processing section which divides the information read out from the information recording section by the information reading section into a plurality of information segments, and gives an identifier uniquely to each divided information segment;
• and
• an information transmitting section which in addition to repeatedly transmit via communication a bundle of identifiers including the identifier within a first period of time, transmits the information segment for which a request for transmission is received from the information receiving device.

An information receiving device for displaying information transmitted from an information transmitting device, comprising:

• an information receiving section which receives via communication a bundle of a plurality of information segments obtained by dividing the information and identifiers, each of the identifiers being uniquely given to each of the plurality of information segments;
• an information selecting section which selects an information segment desired to read from the bundle of the information segments and the identifiers received by the information receiving section based on the identifiers:
• an information storing section which stores the information segment desired to read having been selected by the information selecting section;
• an information display section which displays the information segment desired to read having been stored in the information storing section;
• and
• a display control section which controls the information display section,
• wherein the display control section controls the information display section such that in a case where the information receiving section does not receive the identifier given to the information segment desired to read within a second period of time, the information display section stops displaying the information segment desired to read stored in the information storing section.

An information receiving device for displaying information transmitted from information transmitting device, provided with:

• a first information receiving section which receives via communication a bundle of identifiers each of the identifiers being uniquely given to each of information segments obtained by dividing the information;
• an information selecting section which selects an information segment desired to read from the information segments;
• a second information receiving section which transmits a request for transmission of the information segment desired to read having been selected by the information selecting section, and receives the information segment desired to read;
• an information storing section which stores the information segment desired to read having been received by the second information receiving section;
• an information display section which displays the information segment desired to read having been stored in the information storing section;
• and
• a display control section which controls the information display section,
• wherein the display control section controls the information display section such that in a case where the first information receiving section does not receive the identifier given to the information segment desired to read within a second period of time, the information display section stops displaying the information segment desired to read stored in the information storing section.
