Com a evolu o de novos standards de broadcast em todo o mundo e o OTT streaming buscando a posi o de lideran a no consumo de m dia, tanto os codecs de v deo quanto os de udio de pr xima gera o v m ganhando for a. Embora formatos de v deo emergentes como VVC/H.266 ou AV1 sejam os principais impulsionadores dessas iniciativas, os workflows de produ o de Next Generation Audio (NGA) ainda exigem mais aten o e mais pesquisa e desenvolvimento, especialmente quando o objetivo s o eventos ao vivo. Em ambientes on-premises, workflows de NGA j s o utilizados h muitos anos. Para pipelines cloud e h bridas, a discuss o continua em torno da estrutura ideal.
O processo de produ o para eventos em tempo real, como esportes e concertos, complexo, independentemente de o destino ser broadcast de TV ou workflows de adaptive bitrate streaming. A etapa de authoring de udio imersivo baseado em objetos, necess ria para criar conte do NGA como MPEG-H Audio, requer uma intera o humana cuidadosa.
O Codec NGA em Foco: MPEG-H Audio O Fraunhofer IIS o principal impulsionador de um dos codecs NGA mais importantes: MPEG-H Audio. Ele oferece som imersivo personalizado, proporcionando uma experi ncia de usu rio sem precedentes. MPEG-H Audio est inclu do nos standards de TV ATSC (Am rica do Norte), DVB (Europa), TTA (Coreia do Sul) e SBTVD (Brasil). De fato, o primeiro servi o terrestre de TV UHD do mundo, na Coreia do Sul, j transmite MPEG-H Audio. No Brasil, ele foi selecionado como o sistema de udio obrigat rio para o servi o de broadcast DTV+ de pr xima gera o do pa s, combinando o codec de v deo de pr xima gera o VVC/H.266 com NGA MPEG-H. Outros pa ses e organiza es, incluindo ATSC 3.0 nos EUA, DVB na Europa e ARIB no Jap o, v m avaliando MPEG-H Audio como formato de udio nico ou suplementar.
Em contraste com formatos de udio tradicionais, com suas mixagens fixas em stereo ou surround, codecs de udio imersivo como MPEG-H tratam os elementos sonoros individuais - por exemplo, di logos, coment rios, m sica e sound effects - como objetos de udio separados. Cada objeto acompanhado por metadata que define, por exemplo, o que o elemento de udio representa, onde ele deve ser posicionado, quando est ativo ao longo do tempo, como deve ser renderizado em diferentes dispositivos de playback, qual interatividade do usu rio permitida ou quais s o suas caracter sticas de loudness.
Os workflows cl ssicos de produ o NGA on-premises est o bem estabelecidos e v m operando de forma confi vel h muitos anos. No entanto, broadcasters tendem cada vez mais a mover partes dos workflows de produ o MPEG-H para a cloud, a fim de reduzir custos de hardware e aumentar a flexibilidade. Como resultado, necess rio repensar e adaptar a abordagem atual, na qual v deo e udio de origem - com ou sem metadata - precisam ser transferidos e processados de maneiras diferentes. Para a NAB 2026, v rias empresas l deres de software e provedores de tecnologia uniram esfor os para apresentar uma Proof of Concept (POC) de como um workflow de produ o MPEG-H na cloud pode ser estruturado.
Uma Colabora o nica entre Parceiros L deres do Mercado de M dia
Para a POC na NAB, cinco empresas se uniram para apresentar uma cadeia de produ o NGA em tempo real na cloud. Cada empresa contribui para o showcase com sua expertise comprovada no mercado de broadcast:
Fraunhofer IIS, a organiza o de pesquisa por tr s da tecnologia MPEG-H Audio, fornece bibliotecas de encoding, decoding e player que viabilizam toda a experi ncia NGA, desde a produ o at o playback.
J nger Audio contribui com sua profunda expertise em processamento de udio por meio da plataforma flexAI, que executa a tarefa complexa de metadata authoring e rendering em tempo real. A flexAI permite que broadcasters criem e gerenciem streams de udio e metadata NGA em ambientes de produ o ao vivo, com suporte tanto a workflows S-ADM quanto MPEG-H Control Track.
MainConcept fornece sua tecnologia profissional de AVC, HEVC e VVC Encoder, bem como Decoder SDK, combinada com MPEG-H contribution e emission encoding, garantindo qualidade broadcast de v deo e udio ao longo de toda a cadeia de produ o, incluindo multiplexing e packaging para formatos ABR como HLS, DASH e CMAF.
Techex contribui com o txdarwin, uma sofisticada plataforma de stream processing que faz demultiplexing dos feeds de entrada, roteia o udio para sistemas de processamento e remultiplexa os streams processados, mantendo alinhamento temporal frame-accurate - algo cr tico para aplica es profissionais de broadcast.
AWS fornece a infraestrutura cloud que serve como plataforma para a POC completa. Todas as solu es dos parceiros s o implementadas em inst ncias EC2 dedicadas hospedadas pela AWS.
NAB 2026: Um Workflow de Produ o NGA para a Cloud
Historicamente, o workflow tradicional de produ o ao vivo era baseado em infraestrutura on-premises, ou seja, unidades m veis de Outside Broadcasting (OB), est dios e hardware dedicado, capazes de lidar com udio sem compress o, metadata authoring em tempo real e pipelines de processamento desde contribution at distribution. Hoje, as tecnologias cloud t m a capacidade de estender esses workflows para al m das instala es f sicas, sem comprometer qualidade de udio, lat ncia ou controle criativo, ao mesmo tempo em que evoluem em dire o a maior imers o e personaliza o.
A solu o que Fraunhofer, J nger Audio, MainConcept e Techex configuraram na AWS para a NAB 2026 um primeiro passo para portar o workflow completo de produ o NGA para a cloud. Veja, em resumo, a arquitetura da solu o e o signal workflow:
01 - Audio Capture: Para eventos ao vivo, essa primeira etapa ainda acontece on-site, ou seja, no local do evento, onde fontes individuais de v deo e udio - como coment rios, sons ambientes e efeitos - s o captadas separadamente como sinais discretos d
