Abstract
Se proporciona un método para decodificar datos de video por un dispositivo. Una primera sintaxis de marca en un conjunto de parámetros de imagen es decodificada. La primera marca especifica si los mosaicos dentro de cada corte están en orden de exploración ráster o si los mosaicos dentro de cada mosaico cubren una región rectangular de una imagen. El método determina, con base en la primera sintaxis de marca, si una sintaxis de dirección de corte está presente en el encabezado de corte.
