Abstract (2. Language): 
Bu çalışmada düşük bit oranlarında çalışabilen bir video sıkıştırma tekniği sunulmuştur. Algoritmada, Örtüşmeli Blok Hareket Kompanzasyonu Ayrık Dalgacık Transformu ile birleştirilip ardından Lloyd-Max Nicemleyici ve S ıfır Ağaç Dalgacık Yapısı kullanılmıştır. Bu kodlama tekniğinin en yeni özelliği ise Hiyerarşik Sonlu Durum Vektör Nicemleyicisinin, dalgacik katsayılarını sıkıştırmak için Sıfır Ağaç Dalgacık Yapısı ile birleştirilmiş olmasıdır. Önerilen bu yeni video sıkıştırıcısının MPEG-4 ve Sıfır Ağaç Entropy Kodlama tekniklerinden daha iyi olduğu görülmüştür.

Abstract (Original Language): 
A video compression technique with comparable low bit rates is presented in this paper. The overlapping block motion compansation (OBMC) is combined with discrete wavelet transform which followed by Lloyd-Max quantization and zerotree wavelet (ZTW) structure. The novel feature of this coding scheme is the combination of hierarchical finite state vector quantization (HFSVQ) with the ZTW to encode the quantized wavelet coefficients. It is seen that the proposed video encoder (ZTW-HFSVQ) performs better than the MPEG-4 and Zerotree Entropy Coding (ZTE).
