Abstract

La sincronización y alineación de audio y video o alineación de audio con algún otro reloj externo se vuelven más efectivas o más fáciles tratando la red de fragmentos y red de tramas como valores independientes, pero, no obstante, por cada fragmento la red de tramas es alineada con el inicio de fragmento respectivo. Una pérdida de efectividad de compresión puede ser mantenida bajo cuando se seleccione apropiadamente el tamaño de fragmento. Por otro lado, la alineación de la red de tramas con respecto a los inicios de fragmento permite una forma fácil y sincronizada por fragmentos de manejar los fragmentos en relación con, por ejemplo, flujo unidireccional de audio y video paralelo, flujo bidireccional adaptable por velocidad de bits o similar.
