Abstract

Se describen varias técnicas para la codificación y decodificación de video. Un método ejemplar incluye realizar una determinación, de acuerdo con una regla, sobre si la altura de una subimagen de una imagen de video de un video es menor que la altura de una fila de mosaico de la imagen de video; y realizar, utilizando la determinación, una conversión entre el video y un flujo de bits del video.
