Formatos baseados em MP4 compatíveis com clientes PlayReady

Formatos

Formatar

  • Ativo baseado em MP4. CMAF preferencial.
  • Manifesto DASH.
  • Mesmas chaves ao longo do ativo – chaves não sendo alteradas ao longo do tempo.
  • Mesma chave única para todas as faixas e representações (taxas de bits) ou chaves diferentes para diferentes faixas e representações (taxas de bits). Por exemplo, uma chave diferente pode ser usada para todas as faixas de vídeo acima de 1080p para restringir o acesso à resolução 4K para determinados clientes.

Com suporte

Com suporte na versão 1507 ou superior com a <mspr:pro> marca para o Perfil Dinâmico com manifestos estáticos (conteúdo sob demanda).

Com suporte na versão 1703 ou superior com a <mspr:pro> marca para o Perfil Dinâmico com manifestos dinâmicos (conteúdo ao vivo).

O manifesto DASH contém um objeto PlayReady, incluindo um Cabeçalho PlayReady usando a <mspr:pro> marca no <Period> nó. Se chaves diferentes forem usadas para faixas ou taxas de bits diferentes, o manifesto DASH poderá ter vários objetos PlayReady em vários <AdaptationSet> ou <Representation> nós.

Observação

É possível inserir os Objetos PlayReady dentro dos segmentos de inicialização dos diferentes <AdaptationSet> nós. Se os Objetos PlayReady forem encontrados nos segmentos init e no manifesto, os do manifesto têm precedência.


Os manifestos DASH com uma marca padrão <cenc:pssh> para ativos Sob Demanda e Live têm suporte na versão RS5 ou superior. Nesse caso, todo o conteúdo de uma caixa pssh blindada na base 64 está incluído no manifesto. Não é apenas um objeto PlayReady.

Para aumentar a compatibilidade, a Microsoft recomenda que você gere manifestos DASH que incluam os Objetos PlayReady duplicados e marcas <mspr:pro><cenc:pssh> .
