Abstract: A network packet receiving device that includes packet queues, a credit allocation circuit and a credit management circuit is provided. Each of the packet queues corresponds to a packet transmission channel and receives packets. The credit allocation circuit calculates packet amount of each of the packet queues to control the descriptor credit of each of the packet queues within a credit range. The credit management circuit points each of public entries of a public link list to one of descriptors in a single descriptor buffer. The credit management circuit further receives a credit requesting command from the packet queues to assign the descriptors to the packet queues through the public entries under the condition that the descriptor credit is within a credit range such that a DMA circuit performs a DMA operation on the packets according to the descriptors.

Abstract: Utilizing two LTR frames for improved error recovery. By using two LTR frames, much better performance is achieved in terms of error recovery as the likelihood of the decoder having one of the two LTR frames is very high. When the decoder determines a frame is lost, the decoder provides a fast update request (FUR). The FUR includes a listing of the LTR frames present at the decoder. With this indication of the LTR frames present at the decoder, the encoder utilizes one of the LTR frames, preferably the most recent, to use as a reference to send the next frame as a P frame. The P frame is sent with an indication of the LTR frame used as reference. The use of two LTR frames and the feedback of LTR frames present at the decoder allows the minimization of the use of I frames for error recovery.
