Abstract
RESUMEN Se describen técnicas relacionadas con la derivación de vectores de movimiento en el lado del decodificador (DMVD). Por ejemplo, esta divulgación describe técnicas relacionadas con la aplicación de una o más restricciones a la información de movimiento, tal como un vector de movimiento (MV) derivado mediante DMVD, y/o una diferencia de MV entre un MV inicial y un MV derivado mediante DMVD. En ciertos ejemplos, cuando la restricción se aplica a la DMVD, solo la información de movimiento derivada que satisface la restricción se considera información de movimiento válida. Se pueden imponer condiciones a las restricciones.
