Abstract
processamento paralelo de frente de onda para codificação de vídeo. em um exemplo, um codificador de vídeo pode ser configurado para determinar que uma fatia de uma imagem de dados de vídeo começa em uma fileira de unidades de árvore de codificação (ctus) na imagem em uma posição que não um início da fileira. com base na determinação, o codificador de vídeo pode ser ainda configurado para determinar que a fatia termina dentro da fileira de ctus. o codificador de vídeo pode ser ainda configurado para codificar a fatia com base na determinação de que a fatia termina dentro da fileira de ctus.
