Abstract
Se describe un mecanismo de codificación de video. El mecanismo incluye recibir un flujo de bits que comprende un segmento y un conjunto de parámetros de adaptación (APS) de mapeo de luma con modificación de escala de croma (LMCS) que incluye parámetros LMCS. El mecanismo incluye además determinar que se hace referencia al LMCS APS en datos relacionados con el segmento. El mecanismo incluye además decodificar el segmento usando parámetros LMCS del LMCS APS con base en la referencia al LMCS APS. El mecanismo incluye además reenviar el segmento para su visualización como parte de una secuencia de video decodificada.
