Abstract

dispositivo e método para codificação escalável de informação de vídeo. um dispositivo configurar para codificar informação de vídeo em um fluxo de bits que inclui uma memória e um processador na comunicação com a memória. a memória é configurada a guardar informação de vídeo associada com uma camada de vídeo contendo uma figura atual. o processador é configurado a: determinar se o segmento de fatia de uma extensão de cabeçalho associada com a figura atual está presente no fluxo de bits; e determinar que um ou mais dos bits mais significantes (msbs) de uma ordem de contagem de figura (poc) valores associados com a figura atual não estão presentes no fluxo de bits em resposta a determinação que o segmento de fatia de extensão do cabeçalho associado com a figura atual não está presente no fluxo de bits. o processador pode codificar ou decodificar a informação de vídeo no fluxo de bits.
