Abstract

técnicas de codificação aritmética binária adaptativa ao contexto (cabac) são em geral descritas. os aspectos das técnicas em geral são direcionados para a inicialização de contexto com base em herança. um exemplo de dispositivo de codificação de vídeo inclui uma memória configurada para armazenar dados de vídeo e um ou mais processadores. o(s) processador(es) é(são) configurado(s) para inicializar informação de contexto para uma fatia atual de uma imagem atual, herdando informação de contexto de um bloco previamente codificado de uma imagem previamente codificada dos dados de vídeo armazenados como informação de contexto inicializada para a fatia atual da imagem atual. o(s) processador(es) é(são) adicionalmente configurado(s) para codificar dados da fatia atual utilizando a informação de contexto inicializada.
