Claim 8:
9. An audio forwarding device, comprising:
a dual-mode radio frequency transceiver configured for establishing a first communication link with an audio source device based on a first wireless communication protocol, establishing a second communication link with an audio playback device based on a second wireless communication protocol, receiving first audio data from the audio source device through the first communication link;
an audio processing unit configured for processing the first audio data to generate second audio data, storing the second audio data into a second buffer, and acquiring the second audio data in the second buffer according to a predetermined encoding frame length, processing a current frame as an empty data frame if the second audio data in the second buffer is not successfully acquired; and
a baseband data and protocol processor configured for transmitting or not transmitting an audio data packet containing the empty data frame to the audio playback device through the second communication link within a current transmission time.
