Abstract: A group of devices connected on a network operate in conjunction with one another to present content. Individual devices may be wirelessly connected to presentation devices such as speakers. Skew is a delay between when content is sent to the presentation device and then output. Drift is a difference in timing of output between two or more presentation devices not synchronized to a common clock. Non-zero values of skew and drift may result in poor content presentation by the group. An actual rate at which data is transferred to a presentation device is measured and compared to an expected rate. This difference is analyzed to determine a drift value. The content to be delivered to the presentation device is resampled. During presentation the combination of the drift and the resampled content reduces skew. The drift value may also be used to lookup a skew value used to delay initial presentation.

Abstract: On the basis of a bitstream (P), an n-channel audio signal (X) is reconstructed by deriving an m-channel core signal (Y) and multichannel coding parameters (a) from the bitstream, where 1?m<n. Also derived from the bitstream are pre-processing dynamic range control, DRC, parameters (DRC2) quantifying an encoder-side dynamic range limiting of the core signal. The n-channel audio signal is obtained by parametric synthesis in accordance with the multichannel coding parameters and while cancelling any encoder-side dynamic range limiting based on the pre-processing DRC parameters. In particular embodiments, the reconstruction further includes use of compensated post-processing DRC parameters quantifying a potential decoder-side dynamic range compression. Cancellation of an encoder-side range limitation and range compression are preferably performed by different decoder-side components. Cancellation and compression may be coordinated by a DRC pre-processor.
