Abstract

processamento de vídeo. é provido um método para derivar um valor para um primeiro elemento de sintaxe, syntax_a. o método compreende determinar se syntax_a está presente em um bitstream. o método compreende, como um resultado ao determinar que syntax_a não está presente no bitstream, derivar o valor de syntax_a para ser igual a um primeiro valor, b, caso uma primeira condição seja satisfeita, ou derivar o valor de syntax_a para ser igual a um segundo valor, c, caso uma segunda condição seja satisfeita.
