Abstract[English]
Technology for low-delay encoding of live video streams in multi-adapter systems can include a host processor and memory comprising instructions which, when executed, cause a computing system to encode, via a first graphics adapter, an I-frame of a live video signal and a first subset of P-frames of the live video signal, encode, via a second graphics adapter, a second subset of P-frames of the live video signal, and combine the encoded video frames from the first adapter and the encoded video frames from the second adapter into an output video bitstream. Frames of the live video signal are divided into the first and second subsets of P-frames on an alternating frame basis, and the I-frame copied from the first graphics adapter to the second graphics adapter prior to encoding the second subset of P-frames, such that encoding the first and second subsets of P-frames occurs essentially in parallel.[French]
L'invention concerne une technologie pour le codage à faible retard de flux vidéo en direct dans des systèmes multi-adaptateurs qui peut comprendre un processeur hôte et une mémoire comprenant des instructions qui, lorsqu'elles sont exécutées, amènent un système informatique à coder, par l'intermédiaire d'un premier adaptateur graphique, une trame I d'un signal vidéo en direct et un premier sous-ensemble de trames P du signal vidéo en direct, coder, par l'intermédiaire d'un second adaptateur graphique, un second sous-ensemble de trames P du signal vidéo en direct, et combiner les trames vidéo codées du premier adaptateur et les trames vidéo codées du second adaptateur en un flux binaire vidéo de sortie. Des trames du signal vidéo en direct sont divisées en premier et second sous-ensembles de trames P sur une base de trame alternée, et la trame I copiée du premier adaptateur graphique au second adaptateur graphique avant le codage du second sous-ensemble de trames P, de sorte que le codage des premier et second sous-ensembles de trames P se produise essentiellement en parallèle.
