Patent ID: 7865255

Claim:
An audio buffering system in a multimedia receiver, the audio buffering system comprising: an audio interface being coupled to an incoming audio signal for generating a digital audio signal having transmitted therein a plurality of data words; a first-in-first-out (FIFO) buffer for receiving the digital audio signal comprising a plurality of cells being organized sequentially for holding data words of the digital audio signal, wherein a first cell of the FIFO buffer has an input receiving the digital audio signal; and a first shift register having a plurality of bits being organized serially, wherein a first bit of the first shift register directly receives an output from a last bit of the first shift register, and each bit of the first shift register is coupled to a corresponding bit in an outputted data word of the FIFO buffer, wherein each data word of the digital audio signal further comprises a validity indicator, and in response to the validity indicator indicating an error condition, the first shift register shifts bits output from the last bit of the first shift register directly back into the first bit of the first shift register; wherein the first shift register is selectively loaded with data words outputted from the FIFO buffer.
