Abstract
A method of packetizing digital information for packet-switched communications includes placing, at a transmitting device with memory and a processor, a most significant bit of a digital voice sample into a variable-length most significant bit packet having a high transmission priority for transmission over a packet-switched network in which a node receives the packet and independently determines how to route the packet. At the transmitting device, a least significant bit of the digital voice sample is placed into a variable-length least significant bit packet having a low transmission priority for transmission over the packet-switched network. Prioritization of packets as having a high transmission priority or low transmission priority is independent of content characteristics of digital voice samples with elements contained therein.
