Patent ID: 8295297

Claim:
A transmitting system comprising a host device and a transmitting device that is directly operated by a user, for transmitting, to a display or printing device via the transmitting device by using a one-way communication method based on a particular communication standard, data for display or printing which is stored in the host device, the transmitting device that is directly operated by the user comprising: a memory to which the data for display or printing which has been subjected, by the host device in advance, to protocol conversion based on a communication protocol of the data and data modulation based on a communication method for the data, is written from the host device; a logical device for reading the converted and modulated data for display or printing out of the memory and outputting the read converted and modulated data for display or printing to a transmitting section without performing protocol conversion and data modulation, so as to transmit, to the display or printing device, the converted and modulated data for display or printing stored in the memory; and the transmitting section for transmitting, to the display or printing device, the converted and modulated data for display or printing which is read from the memory, without performing the protocol conversion and the data modulation in the transmitting device, wherein on the converted and modulated data for display or printing to be written to the memory in the transmitting device, the host device performs the protocol conversion based on a one-way communication protocol.
