ABSTRACT:
A device and method for providing real time compensation for packet loss in the transmission of facsimile data over packet networks to avoid the generation of page loss data and the termination of facsimile transmission. Facsimile devices have a low tolerance for interruptions in transmission. Packet networks commonly have a transmission interruption rate above the tolerance of facsimile equipment. In order to compensate for transmission interruption, the present invention teaches the buffering of facsimile data by scan line at the receiving end, the evaluation of buffered scan lines for packet loss and the discarding of scan lines having packet loss to conceal the packet loss from the receiving facsimile equipment to avoid detection of page errors by the receiving facsimile equipment which could cause loss of facsimile transmission. Discarding damaged scan lines instead of repair or replacement saves computational time and storage capacity, allowing for real-time compensation to provide for optimal transmission.
