Abstract

Bir sikistirilmis ses/video alicisi, dekompres edilmis ses ve video sinyallerinin görece eszamanlanmasinin ölçülmesi için devreyi kapsamaktadir. Ses ve video sinyali eszamanlamasi bir birinci degerler araligi dahilinde ise, alici içindeki eszamanlama devresi sinyalleri uygun biçimde zaman içinde hizalamak için girisimde bulunacaktir. Seçenek olarak ise, fiili es-zamanlamanin birinci araligi asmasi durumunda, sinyalleri es-zamanlama girisimleri askiya alinmakta ve es-zamanlanmamis dekompres edilmis ses ve video sinyalleri temin edilmektedir.
