Title (EN) QUALITY TAGGING IN ADAPTIVE BITRATE TECHNOLOGIES
(FR) MARQUAGE DE QUALITÉ DANS DES TECHNOLOGIES DE DÉBIT BINAIRE ADAPTATIF
Abstract:
(EN) A method is provided for tagging a quality metric in adaptive bitrate (ABR) streaming, which allows a client to intelligently select a variant bitrate stream using the tagged quality metric. The method includes encoding multiple streams of video data at variant bitrates, each bitrate stream having a plurality of chunks, computing a quality metric for each chunk of each stream, and tagging the quality metric with each chunk of each stream.
(FR) L'invention porte sur un procédé de marquage d'une métrique de qualité dans une diffusion en continu à débit binaire adaptatif (ABR), ce qui permet à un client de sélectionner de manière intelligente un flux à débit binaire variable à l'aide de la métrique de qualité marquée. Le procédé consiste à coder de multiples flux de données vidéo à des débits binaires variables, chaque flux de débit binaire ayant une pluralité de segments, à calculer une métrique de qualité pour chaque segment de chaque flux, et à marquer la métrique de qualité au moyen de chaque segment de chaque flux.
