Abstract
Dönüşüm katsayılarını kodlamak ve kodunu çözmek için bir yöntem ve bir aygıt açıklanır. Kodlama yöntemi bunları içerir: önceden belirlenmiş bir tarama sırasına göre bir dönüşüm katsayısı bloğunun dönüşüm katsayılarının kodlanması ve her bir gruptaki bir dönüşüm katsayısı bloğunun son bir grubu kodlanana kadar bir dizi dönüşüm katsayısının kodlanması; elde edilen sıfır olmayan dönüşüm katsayıları haritasının, dönüşüm katsayılarının mutlak değerlerinin ve sıfır olmayan dönüşüm katsayılarının pozitif ve negatif işaretlerinin depolanması; son grup kodlandığında, son grupta kodlanan sıfır olmayan dönüşüm katsayılarının bir haritası elde edildikten sonra, depolanan sıfır olmayan dönüşüm katsayıları haritasını ve son grupta kodlanmış sıfır olmayan dönüşüm katsayılarının bir bit akışına kodlanması ve mutlak dönüşüm katsayılarının değerleri ve son grupta kodlanmış sıfır olmayan dönüşüm katsayılarının pozitif ve negatif işaretlerinin elde edilmesinden sonra, depolanan mutlak dönüşüm katsayıları değerlerinin ve sıfır-olmayan dönüşüm katsayılarının pozitif ve negatif işaretlerinin ve dönüşüm katsayılarının mutlak değerlerinin ve son grupta kodlanan sıfır olmayan dönüşüm katsayılarının pozitif ve negatif işaretlerinin bit akışına kodlanması. Kodlama ve kod çözme verimliliği arttırılabilir.
