Methods for transmitting and receiving an audio stream are provided. For transmission, the method involves obtaining a frame of an audio signal, determining a number of source blocks to divide the frame of the audio signal into and a number of parity blocks to generate for forward error correction, wherein the number of source blocks and the number of parity blocks are determined based on characteristics of a wireless communication protocol to be used. The wireless communication protocol may be BLUETOOTH. The parity blocks are usable by a decoder to reconstruct one or more corrupted or missing source blocks and may be obtained by means of Reed-Solomon encoding.

Wireless transmission and reception of packetized audio data in combination with forward error correction

The present document discloses a method for fading discontinued audio feeds for replay by a speaker. In particular, the method may first comprise receiving an input audio feed comprising a plurality of samples. The method may further comprise determining whether the input audio feed is discontinued. And, when discontinuity of the input audio feed is detected, the method may comprise generating an intermediate audio signal comprising a plurality of samples based on the discontinued input audio feed. In particular, the intermediate audio signal may be generated based on a last portion of the discontinued input audio feed that has been output for replay. In addition, the method may further comprise applying a fadeout function to the intermediate audio signal to generate a fadeout audio signal. Finally, the method may comprise outputting the fadeout audio signal for replay by the speaker.

Methods, apparatus and systems for low latency audio discontinuity fade out

The present document describes a method () for providing combined audio and video content from a source device () to an audio sink device () and to a video sink device (). The method () comprises determining () latency information regarding the video latency for processing the video content and the audio latency for processing the audio content of the combined audio and video content along the device chain () between the source device () and the audio and video sink devices (). Furthermore, the method (comprises delaying () the audio content or the video content in dependence of the latency information, and providing () the combined audio and video content with the delayed audio content or the delayed video content.
