Abstract

IMPLEMENTAÇÃO ESCALÁVEL PARA REGIÕES DE ESTIMATIVA PARALELA E MOVIMENTO. Um dispositivo de codificação de vídeo configurado de acordo com alguns aspectos dessa revelação inclui uma memória configurada para armazenar uma pluralidade de candidatas a vetor de movimento. Cada candidata a vetor de movimento pode corresponder pelo menos uma de uma pluralidade de unidades de predição (PUs) divididas em uma região de estimativa paralela de movimentos (MER). O dispositivo de codificação de vídeo inclui também um processador em comunicação com a memória. O processador é configurado para selecionar um subconjunto da pluralidade de candidatas a vetor de movimento para incluir em uma lista de candidatas à fusão. A seleção pode se basear em um nível de prioridade de cada candidata a vetor de movimento. O processador pode ser configurado ainda para gerar a lista de candidatas à fusão para incluir as candidatas selecionadas a vetor de movimento.
