Abstract: A system and method of interfacing between a source media device, a destination media device and wireless speakers. A media stick provides the output video signal to the destination media device via a wired signal path, and provides the output audio signal to the wireless speakers via a wireless signal path. In this manner, a user may use a single device—the media stick—as both a connector between the devices and to provide the audio signal to the wireless speakers.

Abstract: Embodiments are directed processing adaptive audio content by determining an audio type as one of channel-based audio and object-based audio for each audio segment of an adaptive audio bitstream, tagging the each audio segment with a metadata definition indicating the audio type of the corresponding audio segment, processing audio segments tagged as channel-based audio in a channel audio renderer component, and processing audio segments tagged as object-based audio in an object audio renderer component that is distinct from the channel audio renderer component. Object-based audio is rendered through an object audio renderer interface that dynamically adjusts processing block sizes of the object audio segments based on timing and alignment of metadata updates and maximum/minimum block size parameters.
