Abstract

um aparelho configurado para codificar dados de vídeo compreendendo uma memória configurada para armazenar um bloco de dados de vídeo e um ou mais processadores em comunicação com a memória. os um ou mais processadores são configurados para determinar um modo de codificação para codificar o bloco de dados de vídeo entre um ou mais modos de codificação, em que o modo de codificação é determinado com base em um tamanho de elemento de sintaxe máximo, codificar o bloco de dados de vídeo em uma pluralidade de subfluxos de acordo com o modo de codificação determinado para criar uma pluralidade de subfluxos codificados de dados de vídeo, armazenar a pluralidade de subfluxos codificadas de dados de vídeo nos respectivos buffers de primeiro a entrar, primeiro a sair (fifo), e multiplexar a pluralidade de subfluxos codificados em um fluxo de bits para transmitir para um decodificador de vídeo.
