The present application describes a method () for providing personalized audio to a user. The method () comprises receiving () a manifest file () for a media element from which audio is to be rendered, wherein the manifest file () comprises a description () for a plurality of different presentations () of audio content of the media element. In addition, the method () comprises selecting () a presentation () from the plurality of presentations () based on the manifest file (). The method () further comprises receiving () a list of audio track objects comprised within the media element, and selecting () an audio track object from the list of audio track objects, in dependence of the selected presentation ().

Methods and devices for providing personalized audio to a user

A method for adaptive streaming of media content with bitrate switching is described, wherein the media content comprising a plurality of consecutive media segments. The method comprising, at a media streaming server: transmitting a segment of the media content encoded in a first coding mode having a first bitrate; receiving an indication for a coding mode switch to a second coding mode having a second bitrate and in response transmitting a transition segment for transitioning between the first coding mode and the second coding mode; and transmitting another segment of the media content encoded in the second coding mode.

Adaptive streaming of media content with bitrate switching

The present document describes a method () for personalizing audio content. The method () comprises receiving () a manifest file () for the audio content. The manifest file () comprises at least one adaptation set () referencing an audio bitstream (), where the audio bitstream () comprises a plurality of audio objects (), and a plurality of different preselection elements () for the adaptation set (), wherein the different preselection elements () specify different combinations of the plurality of audio objects (). The method () further comprises selecting () a preselection element () from the plurality of different preselection elements (), and causing () rendering of an audio signal which depends on the selected preselection element ().

Methods and devices for personalizing audio content

The present document relates to the determination of a 200 bitrate related to an encoded bitstream, and describes a method for determining an estimate of a bitrate of a bitstream comprising a sequence of frames comprising a varying number of bitsand corresponding to excerpts of an audio and/or video signal. At least two frames of the sequence of frames comprise a parameter indicative of a processing delay for the corresponding frame. The method comprises determining: a total number of bits for a subsequence of frames from the bitstream; a corrected number 201 of frames based on a number of frames comprised within the subsequence and the parameters of at least two frames of the subsequence; and a lower bitrate bound and an upper bitrate bound of the bitrate based on the total number of bits, the corrected number of frames and a frame rate of the bitstream.

Method for bitrate signaling and bitstream format enabling such method

Methods for generating a transport stream (e.g., an MPEG-2 transport stream) such that the transport stream has at least one perfect splicing property, and/or such that the transport stream is indicative of at least one audio/video program and includes metadata indicative of whether the program has a perfect splicing property. Other aspects are methods for splicing such a transport stream, audio/video processing units (e.g., splicers) configured to perform any embodiment of the inventive method, and audio/video processing units which include a buffer memory which stores at least one segment of transport stream generated in accordance with any embodiment of the inventive method.
