Abstract

a presente invenção se refere a métodos de transmissão de domínio gráfico que usam um pipeline de compactação adaptativa para alcançar o espelhamento de tela com baixa latência entre um dispositivo de origem e um dispositivo coletor. um dispositivo de origem captura uma pluralidade de quadros de domínio gráfico, cada um dos quadros de domínio gráfico incluindo um ou mais tokens de comando gráfico. o dispositivo de origem usa um pipeline de compactação adaptativa para compactar os quadros de domínio gráfico com base em uma ou mais características dos quadros, e o pipeline de compactação adaptativa é configurado para executar pelo menos uma dentre transmissão de textura escalável, predição baseada em quadros, pulo de quadros ou compactação de dados. o dispositivo de origem transmite os quadros compactados a um dispositivo coletor e exibe uma imagem renderizada dos quadros de domínio gráfico em sincronização de tempo com uma imagem renderizada correspondente dos quadros compactados exibidos no dispositivo coletor.
