    Abstract: An apparatus is provided. The apparatus has an interface for receiving media information, wherein the media information indicates a segment data rate for each of a plurality of media data segments and further indicates a quality value for each of the plurality of media data segments. Moreover, the apparatus has a processor for selecting one or more selected segments from the plurality of the media data segments depending on the segment data rates of the plurality of media data segments, depending on the quality values of the plurality of media data segments and depending on an available data rate of a communication resource. The interface is configured to transmit a request requesting the one or more selected segments. Moreover, the interface is configured to receive the one or more selected segments being transmitted on the communication resource.

    Abstract: An apparatus for transmitting user data to a server system including one or more servers includes a content encoder for encoding a plurality of portions of the user data to obtain a first data stream, wherein the content encoder is configured to encode each of the plurality of portions with a bandwidth-dependent quality which depends on a bandwidth that is available for transmitting the first data stream from the apparatus to the server system, and includes a transmitter for transmitting the first data stream from the apparatus to the server system. The content encoder is configured to encode two or more of the plurality of portions of the user data to obtain a second data stream, wherein the content encoder is configured to encode each of the two or more of the plurality of portions with a predefined quality.

    Abstract: A streaming media playback device is provided for playing multimedia presentations with segments encoding video data at different quality levels for adaptive streaming through a network from a server, for example based on MPEG DASH. The streaming media playback device selects segments at a given quality level from those available at the server based on an adaptive bitrate setting and an oscillation measure. The adaptive bitrate setting is selected based on network bandwidth conditions. The oscillation measure provides an indication of how often the device switches between segments of different quality levels. The next segment is selected based on the adaptive bitrate setting unless the oscillation measure exceeds a threshold.
