Abstract: A method and system for synchronizing in real-time the voice media of a conversation conducted over a network between a first communication device and a second communication. The method includes at each of the first and second communication devices progressively storing in first and second storage elements and transmitting the voice media created using the first and second communication devices to the other communication device respectively. Both the first and second communication devices store in the first and second storage elements the progressively received media from the other device respectively. A mechanism to continually review, ascertain and request the media stored in the first storage element, but not the second storage element, and vice-versa is provided to ensure that the two storage elements contain the same voice media. As a result, the first and second storage elements each maintain real-time synchronized copies of the voice media of the conversation respectively.

Abstract: A method for progressively synchronizing stored copies of indexed media transmitted between nodes on a network. The method includes progressively transmitting available indexed media from a sending node to a receiving node with a packet size and packetization interval sufficient to enable the near real-time rendering of the indexed media, wherein the near real-time rendering of the indexed media provides a recipient with an experience of reviewing the transmitted media live. At the receiving node, the transmitted indexed media is progressively receive and any indexed media that is not already locally stored at the receiving node is noted. The receiving node further continually generates and transmits to the sending node requests as needed for the noted indexed media. In response, the sending node transmits the noted indexed media to the receiving node. Both the sending node and the receiving node store the indexed media.

Abstract: A communication device for gracefully extending the range and/or capacity of voice communication systems. The communication device includes a persistent storage device configured persistently store the voice media either generated when using the communication device or received over the network at the communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, the communication device transmits voice media from persistent storage and stores received voice media in persistent storage at the available usable bit rate on the network. Although latency may be introduced during the back and forth transmissions of a conversation, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations.

Abstract: A method for transferring a complete copy of media designated as time sensitive over a network. The method involves ascertaining if conditions on the network are adequate to transmit a full bit rate representation of media designated as time-sensitive at a first bit rate and a first packetization interval between a sending node and a receiving node over the network, where the full bit rate representation being derived from when the time-sensitive media was originally encoded. If the network conditions are ascertained as being inadequate, then a reduced bit rate representation of the media designated as time-sensitive is generated and transmitted to the receiving node. At the receiving node, receipt reports are generated identifying the received reduced bit rate representation of the media. The receipt reports are transmitted to the sending node, where, in response, the corresponding full bit rate representation of the media is retransmitted.

Abstract: A method for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method involves the persistent storage of voice media on a communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network. Although latency may be introduced, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations. In addition, the capacity and robustness in not being affected by external interferences for both wired and wireless communications is improved.

Abstract: A method for reliably transferring media over a network from a sending node to a receiving node. The method includes ascertaining at the sending node if the media to be transmitted is either time-sensitive or not time-sensitive. For media ascertained as non time-sensitive, the media is transmitted by adjusting the rate of transmission at the sending node based on network conditions. As the non time-sensitive media is received, the receiving node generates one or more low priority requests for the retransmission of any missing non time-sensitive media lost during the transmission. The method also includes transmitting the time-sensitive media from the sending node to the receiving node. As the time-sensitive media is received, the receiving node ascertains if a predetermined acceptable network transmission loss level is met. If met, the receiving node generates one or more low priority requests for the retransmission of any missing time-sensitive media lost during transmission.

Abstract: The present invention is directed to a method for transmitting data over a network. The method includes ascertaining at a first node the need to transmit one or more data streams from the first node to a second node over the network, the one or more data streams including time-based media that is generated either locally or remotely on the network. The method also includes ascertaining at the first node a timeliness preference for reviewing the one or more data streams by one or more recipients respectively. The ascertained timeliness preference for each one of the data streams is either (a) time-sensitive where at least one recipient of the one data stream has indicated an intent to review the one data stream in a near real-time mode as received by the recipient over the network while the time-based media of the one data stream is being generated or (b) less-than time-sensitive.

Abstract: An improved communication apparatus for transmitting media between a sending node and a receiving node during a conversation. When network bandwidth is insufficient to transmit a full bit rate representation of time-sensitive media, the sending node generates and transmits a reduced bit rate representation of the media for the purpose of increasing the ability of the recipient to review the media upon receipt and continue the conversation in the real-time mode when the bandwidth on the network is insufficient to support the transmission of the full bit rate representation. The sending node also transmits media that is ascertained as not time-sensitive only when bandwidth in excess of what is needed for time-sensitive media becomes available.

Abstract: A method for transferring a complete copy of media designated as time-sensitive over a network. The method involves transmitting media designated as time-sensitive from sending node to a receiving node and receiving the media designated as time-sensitive at the receiving node. At the receiving node, any missing media designated as time sensitive is noted. One or more receipt reports are generated at the receiving node and are sent back to the sending node, the receipt reports including a low priority request for retransmission of the identified missing media. In response, the sending node retransmits the low priority request for retransmission, the retransmission occurring when bandwidth on the network in excess of what is needed to transmit time-sensitive media becomes available. Eventually a complete copy of the media including the missing media is obtained at the receiving node after the retransmission.
