Abstract

Se describen técnicas y herramientas para reducir la latencia en codificación y descodificación de video al restringir la latencia debido reordenamiento de cuadros de video, y al indicar la restricción sobre la latencia de reordenamiento de cuadro con uno o más elementos de sintaxis que acompañan datos codificados para los cuadro de video. Por ejemplo, una herramienta de comunicación en tiempo real con un codificador de video establece un elemento de sintaxis que indica una restricción sobre la latencia de reordenamiento de cuadro, que es consistente con las dependencias inter-cuadro entre múltiples cuadros de una secuencia de video, entonces envía el elemento de sintaxis. Una herramienta de comunicación en tiempo real correspondiente con un descodificador de video recibe el elemento de sintaxis que indica la restricción sobre la latencia de reordenamiento de cuadro, determina la restricción sobre la latencia de reordenamiento de cuadro basándose en el elemento de sintaxis, y utiliza la restricción sobre la latencia de reordenamiento de cuadro para determinar cuando un cuadro reconstruido está listo para envío (en términos de orden de salida).
