Efficient transmission of voice silence intervals

A method of receiving varying information interspersed with an interval of substantially unvarying information as a sequence of packets, comprising the steps of:

• in response to receiving a packet during a time interval, transmitting a segment of information carried by the received packet;
• and
• in response to not receiving a packet during a time interval, transmitting a segment of information carried by a last received packet;
• wherein the received packets other than the last received packet carry segments of the varying information and the last received packet carries a segment of the unvarying information.

A method of receiving varying information interspersed with an interval of substantially unvarying information as a sequence of packets, comprising the steps of:

• in response to receiving a packet carrying a segment of the varying information during a time interval, transmitting the segment carried by the received packet;
• in response to receiving a packet carrying an initial segment of the interval of the unvarying information during a time interval, transmitting the segment carried by the received packet;
• in response to not receiving a packet during a subsequent time interval, transmitting again the initial segment of the unvarying information;
• and
• in response to again receiving a packet carrying a segment of the varying information during a time interval, transmitting the segment carried by the received packet.

A method of transmitting voice signals comprising speech signals interspersed with silence signals, comprising the steps of:

• in response to detecting speech signals in the voice signals, transmitting packets carrying the detected speech signals;
• in response to commencing to detect silence signals in the voice signals, transmitting a packet carrying the detected silence signals;
• in response to continuing to detect silence signals in the voice signals, not transmitting any packets;
• and
• in response to again detecting speech signals in the voice signals, again transmitting packets carrying the detected speech signals.

A method of receiving voice signals comprising speech signals interspersed with silence signals, comprising the steps of:

• in response to receiving packets carrying the voice signals, outputting the carried voice signals;
• in response to ceasing to receive the packets carrying the voice signals, repeatedly outputting the voice signals carried by a last received one of the received packets until resumption of receipt of packets;
• and
• in response to resuming to receive packets carrying the voice signals, resuming outputting of the carried voice signals;
• wherein the received packets other than the last received packet carry the speech signals and the last received packet carries a sample of the silence signals.

A method of receiving voice signals comprising speech signals interspersed with silence signals, comprising the steps of:

• in response to each time interval during which a packet carrying a segment of the voice signals is received, transmitting the segment carried by the received packet;
• and
• in response to each time interval during which a packet carrying a segment of the voice signals is not received, transmitting the segment carried by a last received one of the received packets carrying a segment of the voice signals until resumption of receipt of packets;
• wherein the received packets other than the last received packets carry segments of the speech signals and the last received packet carries a segment of the silence signals.

An apparatus for transmitting varying information interspersed with an interval of substantially unvarying information as a sequence of packets, comprising:

• an effector, responsive to receiving either a segment of the varying information or an initial segment of the interval of the unvarying information, of transmitting a packet carrying the received segment;
• and
• an effector, responsive to receiving a segment of the interval of the unvarying information other than the initial segment, of not transmitting a packet;
• the effector of transmitting a packet further responsive to receiving a segment of the varying information subsequently to receiving the segments of the interval of the unvarying information, by transmitting a packet carrying the received segment.

• and
• an effector, responsive to not receiving a packet during a subsequent time interval, of transmitting again the initial segment of the unvarying information;
• and
• the effector of transmitting the segment carried by the received packet further responsive to again receiving a packet carrying a segment of the varying information during a time interval subsequent to not receiving a packet during a time interval, by transmitting the segment carried by the received packet.
