Abstract
Se pueden codificar bloques sin transformación de contenido de video al cambiar selectivamente un orden de escaneo. En algunas implementaciones, un codificador o descodificador puede realizar un proceso de escaneo en un bloque de acuerdo con un orden de escaneo. Cuando el bloque no ha sido transformado, el codificador o descodificador puede cambiar de manera selectiva el orden de escaneo a un orden diferente. Por ejemplo, si el bloque está asociado con un tipo de predicción particular, el orden de escaneo puede ser cambiado a un orden diferente. En otro ejemplo, si el bloque sin transformación tiene un tamaño que es más pequeño que un tamaño predeterminado, el orden de escaneo puede cambiarse a un orden diferente.
