Abstract
Se describen técnicas para mejorar la codificación de transformadas. Se puede obtener un bloque codificado de datos de video, y se puede determinar un ancho y/o una altura del bloque. El ancho se puede comparar con un primer umbral, y/o la altura se puede comparar con un segundo umbral. Se puede determinar una transformada horizontal y una transformada vertical para el bloque en función de la comparación del ancho del bloque con el primer umbral y/o la altura del bloque con el segundo umbral. La transformada horizontal y la transformada vertical se determinan sin decodificar un elemento sintáctico que indique la transformada horizontal y la transformada vertical (por ejemplo, el elemento sintáctico no está en una corriente de bits de video codificado procesada mediante un dispositivo de decodificación). En algunos casos, los datos residuales se determinan usando las transformadas horizontal y vertical, y un bloque de video se determina usando los datos residuales y un bloque predictivo.
