Abstract: Methods, systems, and devices are described for estimating packet loss during media streaming over a data connection. A media player requests segments of an adaptive media stream and monitors variance in the amounts of data received. Increased variance in the amounts of data received can be directly correlated to a higher packet loss experienced by the data connection. The media player can use the estimated packet loss to adapt subsequent segment requests, or to otherwise subsequent behavior by the media player.

Abstract: Systems, devices and methods are provided to support placeshifting of adaptive media streams. A home device acts as an intermediary that passes requests for segments of an adaptive stream from a remote device to a content source. The content source responds with the requested segments, which are forwarded to the remote device. A connection service may be provided to facilitate placeshifting sessions between home and remote devices.

Abstract: Systems, devices and methods are provided to support multiple audio tracks in an adaptive media stream. Segments of the adaptive stream are encoded so that the player is able to locate and request a specific one of the available audio tracks using byte range requests or the like. Audio content can be removed from video segments, or at least moved to the end of the segments so that a byte range request obtains just the video content when the default audio is not desired. The audio content can be obtained from a separate audio segment. Indeed, multiple audio tracks can be packaged into a common audio segment so that byte range requests can obtain just the particular audio track desired.
