Abstract

Ses video senkronizasyonu ve hizalaması veya sesin, diğer bazı harici saatlere hizalanması, parça ızgarasının ve çerçeve ızgarasının bağımsız değerler olarak işlenmesi yoluyla daha etkili veya daha kolay hale getirilir, ancak bununla birlikte her parça için çerçeve ızgarası, ilgili parçanın başlangıcına hizalanır. Sıkıştırma etkinliği kaybı, parça boyutunun uygun şekilde seçilmesi durumunda düşük tutulabilir. Diğer taraftan çerçeve ızgarasının parçaların başlangıçlarına göre hizalanması, örneğin paralel ses video akış, bit hızı uyarlamalı akış veya benzeri ile birlikte parçaların kolay ve parça-senkronize bir şekilde kullanılmasına olanak sağlar.
