Abstract
sistema e método para codificação de vídeo. um codificador inclui circuitos e memória acoplada aos circuitos. o circuito determina se uma unidade de decodificação de pipeline virtual (vpdu) de luma atual deve ser dividida em blocos menores. quando é determinado não dividir a vpdu de luma atual em blocos menores, o circuito prevê um bloco de amostras de croma sem usar amostras de luma. quando é determinado dividir a vpdu de luma em blocos menores, o circuito prevê o bloco de amostras de croma usando amostras de luma. o circuito codifica o bloco usando as amostras de croma previstas.
