Abstract

Se describe un mecanismo de codificación de video. El mecanismo incluye recibir una corriente de bits que comprende un indicador y una imagen que incluye un mosaico con un límite de mosaico. El mosaico se decodifica. Las operaciones de filtrado se realizan a través del límite de mosaico cuando el indicador se establece en un primer valor. Las operaciones de filtrado se omiten a través del límite de mosaico cuando el indicador se establece en un segundo valor. El mosaico se reenvía para su visualización como parte de una secuencia de video decodificada.
