CONTEXTUAL INFORMATION FOR AUDIO-ONLY STREAMS IN ADAPTIVE BITRATE STREAMING

摘要

A method is provided to presenting contextual information during adaptive bitrate streaming to allow play of an audio-only variant. The method includes receiving an audio-only variant of a video stream, calculating bandwidth headroom, receiving contextual information that provides descriptive information about visual components of the video stream that has a bitrate less than the bandwidth headroom, and presenting the contextual information to users while playing the audio-only variant.

主权项

1. A method of presenting contextual information during adaptive bitrate streaming, comprising:
receiving, with a client device, an audio-only variant of a video stream from a media server, wherein said audio-only variant comprises audio components of said video stream; calculating bandwidth headroom by subtracting a bitrate associated with said audio-only variant from an amount of bandwidth currently available to said client device; receiving, with said client device, one or more pieces of contextual information from said media server, wherein said one or more pieces of contextual information provide descriptive information about visual components of said video stream, and wherein the bitrate of said one or more pieces of contextual information is less than the calculated bandwidth headroom; playing said audio components for users with said client device based on said audio-only variant; and presenting said one or more pieces of contextual information to users with said client device while playing said audio components based on said audio-only variant.
