    Abstract: A system and method is described herein in which an audio source wirelessly transmits audio content to a first audio sink over one wireless link and to a second audio sink over another wireless link. The two audio sinks also exchange forward error correction (FEC) streams over a link between the two audio sinks, wherein the FEC streams are generated by FEC encoding the audio content received from the audio source. The audio sinks advantageously use the exchanged FEC information to synchronize the playback of the audio content as well as to improve the robustness of the wireless links with the audio source in a manner that does not consume additional bandwidth on those links.

    Abstract: A system and method for discarding or inserting audio frames in a jitter buffer is described. The system and method provides improved audio quality as compared to conventional jitter buffer management systems. In one embodiment, buffer control logic determines whether to discard audio frames to be stored in a jitter buffer or to insert audio frames among audio frames to be output from a jitter buffer based not only on the number of audio frames currently stored in the jitter buffer but also based on the power of the current audio frame to be stored in or output from the jitter buffer. The system and method is generally applicable to any wireless or wired communication system in which audio signals are transmitted between entities operating in different clock domains.

    Abstract: In a Bluetooth™ Sub-band Codec (SBC), the size of a bit pool allocated for encoding is adapted in a manner that is dependent upon the audio content that is being encoded. In one implementation, the size of the bit pool is increased during periods when the audio input signal represents an active audio signal, such as speech or music, and decreased when the audio input signal represents background noise or silence. This has the effect of increasing the bit rate (and thus the audio quality) in the presence of speech or music but decreasing the bit rate (and thus the audio quality) in the presence of background noise or silence. By adapting the size of the bit pool in this manner, the quality of the encoded bit-stream transmitted from the SBC encoder may be improved or power may be conserved depending upon the implementation.

    Abstract translation: 在蓝牙(TM)子频带编解码器(SBC)中,分配用于编码的比特池的大小以取决于正被编码的音频内容的方式进行调整。 在一个实现中,当音频输入信号表示诸如语音或音乐的有效音频信号的时段期间,比特池的大小增加,并且当音频输入信号表示背景噪声或静音时,位池的大小减小。 这具有在存在语音或音乐的情况下增加比特率(并因此提高音频质量)但是在存在背景噪声或静音的情况下降低比特率(并因此降低音频质量)的效果。 通过以这种方式调整比特池的大小,可以根据实现来改善从SBC编码器发送的编码比特流的质量或功率可以被保存。
