Regarding claim 38, Ferrari further teaches wherein the first packet header information is a complete packet header information of the audio source device; and the first buffer is configured to store the complete packet header information; and the data buffered in the common buffer is at least a part of the complete packet header information (Figs. 1A-C and 7 and Sections 0053-0058, 0076-0077, 0082-0083, and 0093, packet header information etc.).
Regarding claim 39, Ferrari further teaches wherein the information processing module comprises a second information processing unit, configured to store a third packet header information locally, wherein the third packet header information is packet header information of the audio source device; wherein the common buffer is configured to buffer a fourth packet header information obtained when the RF receiver apparatus monitors the forwarding information, wherein the fourth packet header information is the packet header information of the signal received by the RF receiver apparatus; wherein the second information processing unit is configured to perform a correlation operation on the third packet header information and the fourth packet header information to obtain a forwarding correlation result, and determine, when the forwarding correlation result is greater than a second threshold, that Link 2 is the link on which information is monitored (Figs. 1A-C and 7 and Sections 0053-0058, 0076-0077, 0082-0083, and 0093, packet header information etc.).
Regarding claim 40, Ferrari further teaches wherein the second information processing unit comprises a second buffer, configured to store the third packet header information; and a second correlation subunit, having an input end connected to an output end of the second buffer and an output end of the common buffer, wherein the second correlation subunit is configured to perform the correlation operation on the third packet header information and the fourth packet header information to obtain the forwarding correlation result, and determine, when the forwarding correlation result is greater than the second threshold, that Link 2 is the link on which information is monitored (Figs. 1A-C and 7 and Sections 0053-0058, 0076-0077, 0082-0083, and 0093, packet header information etc.).
Regarding claim 41, Ferrari further teaches wherein the packet header information of the audio source device comprises a front part and a rear part, with the rear part lagging behind the front part in time sequence; and the second buffer is configured to store the rear part, and the common buffer is configured to buffer the data information corresponding to the length of the rear part (Figs. 1A-C and 7 and Sections 0053-0058, 0076-0077, 0082-0083, and 0093, packet header information etc.).
Regarding claim 42, Ferrari further teaches wherein when information is monitored on both Link 1 and Link 2, the RF receiver apparatus receives, via Link 1 in a preset frequency band, the current audio data retransmitted by the audio source device, and simultaneously receives, via Link 2 in the same preset frequency band, the current audio data forwarded by the first audio playback device (Figs. 1A-C and Sections 0053-0058, 0076-0077, and 0093, when one of the audio hearing buds fails to receive the audio signal then the signal is forwarded etc.).
