Abstract

SISTEMA E MéTODO DE SERVIDOR DE VìDEO SOB DEMANDA Uma arquitetura de Servidor de Vídeo sob Demanda (100, 200, 300) transmite uma pluralidade de programas précodificados tendo taxas de bits diferentes ao longo de um canal de largura da banda fixa (11). Para cada programa, um gerador (12~ o~-12~ p~~ -~~ 1~, 110, 210) gera uma pluralidade de representações de taxas de bits diferentes para cada programa. Cada gerador também fornece informação de controle a cada uma de uma pluralidade de janelas de tempo sucessivas T para cada representação de taxa de bits. A informação de controle fornece uma taxa de bits e uma medida de qualidade durante cada janela de tempo T. A informação de controle permite a um multiplexador estatístico (16, 160, 260) selecionar uma representação de taxa de bits para cada programa durante cada janela de tempo T para maximizar a qualidade das representações selecionadas ao mesmo tempo em que não excede a capacidade do canal disponível total.
