Source and diversity rate equal to a first transmission rate

摘要

Packets of real-time information are sent with a source rate greater than zero kilobits per second, and a time or path or combined time/path diversity rate initially being zero kilobits per second. This results in a quality of service QoS, optionally measured at the sender or the receiver. When the QoS is on an unacceptable side of a threshold of acceptability, the sender sends diversity packets at an increased rate. Increasing the diversity rate while either reducing or maintaining the overall transmission rate is new. CELP-based multiple-description data partitioning sends the base or important information plus a subset of fixed excitation in one packet and sends the base or important information plus the complementary subset of fixed excitation in another packet. Reconstruction produces acceptable quality when only one of the two packets is received and better quality when both packets are received. Reconstruction provides for single and multiple lost packets.

1. A process of sending packets on a network, comprising:
A. sending source packets of real-time, voice information from a sender to a receiver on the network at a first source rate that is equal to a first transmission rate; B. receiving at the sender packet loss information based on a loss of source packets at the receiver; C. comparing in the sender the packet loss information with a threshold number; and D. when the packet loss information is greater than the threshold number, sending the source packets at a second source rate and sending at least one of time and path diversity of the real-time, voice information at a first diversity rate, the sum of the second source rate and the first diversity rate being equal to the first transmission rate.
