Abstract

Un método de decodificación incluye encontrar un final del bit de mosaico con un primer valor y bits de alineación de bytes en una corriente de bits de video, lo cual indica que un bloque de árbol de codificación actual (CTB) es un último CTB en un mosaico; encontrar un final de bit de fila de CTB con el primer valor y los bits de alineación de bytes en la corriente de bits de video, lo cual indica que el procesamiento paralelo de forma de onda (WPP) está habilitado y que el CTB actual es el último CTB en una fila de CTB pero no el último CTB en el mosaico; y reconstruir la pluralidad de CTBs en el mosaico con base en el final del bit de mosaico con el primer valor, el final del bit de fila de CTB con el primer valor, y los bits de alineación de bytes.
