Title:
CORRECTION METHOD OF MESSAGE AT INSIDE OF EQUIPMENT
Document Type and Number:
Japanese Patent JPH07107074
Kind Code:
A
Abstract:
PURPOSE: To allow a receiver to receive and decode a message, even if a transmission state deteriorates due to disturbances on an information transmission line. CONSTITUTION: This method corrects a message which is transmitted between a transmitter AE and a receiver AR connecting to a distribution line. The transmitter AE sends a message, together with a request to affirmative reply by the receiver at a 1st transmission speed. When no acknowledgement is received, the transmitter sends a correction message MC, including information elements and corrected algorithm generated by the transmitter side by comparing bits desired to be sent with bits sent actually through the distribution line at a 2nd transmission speed, together with a request of an acknowledgement by the receiver synchronously with a frequency of power transmitted through the distribution line. In the case that the corrected algorithm is equal to an identification algorithm, when the transmitter receives the acknowledgement of the corrected message, the transmitter sends the message desired of transmission together with a request for the acknowledgement by the receiver at a 2nd transmission speed. When no acknowledgement is received, the transmitter transmits the message by another transmission form.
