Abstract

Das Verfahren zur Datenübertragung von einem Programmiergerät zu einem elektronischen Steuergerät komprimiert die zu übertragenden Daten mit zwei verschiedenen Huffman-Codierbäumen, vorzugsweise mit einem 16-Bit und einem 8-Bit Codierbaum. Die mit unterschiedlichen Codierbäumen codierten Datenworte werden durch ein Kennungsbit voneinander unterschieden.
