Abstract: Computer code is configured to support a conversation among participants over a communication network. The computer code is configured to (i) progressively store the incoming and outgoing messages of a conversation on a communication device, (ii) display the message history of the conversation on the communication device, (iii) provide rendering options on the communication device, (iv) selectively transition participation in the conversation between a real-time mode and a time-shifted mode and (v) designate an interrupt mode for the conversation.

Abstract: A telecommunication and multimedia management apparatus and method that supports voice and other media communications and that enables users to: (i) participate in multiple conversation modes, including live phone calls, conference calls, instant voice messaging or tactical communications; (ii) review the messages of conversations in either a live mode or a time-shifted mode and to seamlessly transition back and forth between the two modes; (iii) participate in multiple conversations either concurrently or simultaneously; (iv) archive the messages of conversations for later review or processing; and (v) persistently store media either created or received on the communication devices of users. The latter feature enables users to generate or review media when either disconnected from the network or network conditions are poor and to optimize the delivery of media over the network based on network conditions and the intention of the users participating in conversations.

Abstract: A system for progressively synchronizing stored copies of indexed media transmitted between nodes on a network. The system includes a transmitter at the sending node configured to progressively transmit available indexed media 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. The system also includes a receiver at the receiving node that progressively receives the transmitted indexed media and continually notes any indexed media that is not already locally stored at the receiving node. The receiver also continually generates and transmits to the sending node requests as needed for the noted indexed media. In response, the transmitter at the sending node transmits the noted indexed media to the receiving node.

Abstract: A voice and text mail application method and apparatus capable of supporting both synchronous and asynchronous voice communication. The application is configured to (i) simultaneously and progressively store media of an incoming message as the media is received at a communication device over the network and (ii) provides a “catch up” rendering option which enables the rendering of previously received media of the message starting at any previous point of the message and to catch up the rendering to the current point or head of the message as the media of the message is being received. By rendering the previously received media of the incoming message out of storage at a rate faster relative to when the media of the incoming message was originally encoded, eventually the rendering will catch up and seamlessly transition the rendering from an asynchronous time-shifted mode out of storage to a synchronous mode as the media of the message is received over the network.

Abstract: A communication application configured to support a conversation among participants over a communication network. The communication application is configured to (i) support one or more media types within the context of the conversation, (ii) interleave the one or more media types in a time-indexed order within the context of the conversation, (iii) enable the participants to render the conversation including the interleaved one or more media types in either a real-time rendering mode or time-shifted rendering mode, and (iv) seamlessly transition the conversation between the two modes so that the conversation may take place substantially live when in the real-time rendering mode or asynchronously when in the time-shifted rendering mode.

Abstract: A mobile communication device and method for reducing exposure to radio frequency (RF) energy during outgoing and incoming transmissions. During outgoing transmissions, media is stored in a local storage element on the mobile communication device as the media is being created. When the device is positioned a safe distance away from the user, the media is transmitted out of storage over the network to the recipient. Alternatively for incoming transmissions, media is stored on the network as it is created. While the wireless communication device is a safe distance away from the user, the media stored on the network is transmitted to the mobile communication device, where it is locally stored. The user of the mobile communication device can then review the incoming media at an arbitrary later time out of storage. As a result, the exposure of the user of the mobile communication device to RF energy for both outgoing and incoming transmissions is either substantially reduced or eliminated altogether.

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 providing on a Push To Talk (PTT) communication network time-shifting capabilities to a user of a PTT communication device. The method involves progressively receiving time-based media at a node on the PTT communication network from a sending device and progressively storing the received time-based media in a time-shifting buffer located at the node as the time-based media is progressively received. In response to rendering control instructions received from the user of the PTT communication device, the method further includes controlling the rendering of the time-based media at the PTT communication device in either (i) a near real-time mode as the time-based media is progressively received at the node or (ii) in a time shifted mode at an arbitrary later time after the receipt and storage of the time-based media in the time-shifting buffer.

Abstract: An method for improving the ability of a recipient to review time-sensitive media upon receipt when network conditions are poor. The method includes ascertaining if media to be sent from a sending node to a receiving node is time-sensitive and ascertaining if there is sufficient bandwidth for transmitting a full bit rate representation of the media at a first bit rate and at a first packetization interval. If the bandwidth is sufficient, the full bit rate representation is transmitted. If the bandwidth is insufficient, then a reduced bit rate representation of the media is generated and transmitted.

Abstract: An application for gracefully extending the range and/or capacity of voice communication systems. The application includes a module for the persistent storage of voice media on a communication device as the voice media is created. When the usable bit rate on the network is poor and below that necessary for conducting live communication of the voice media, a transmit module transmits the voice media out of storage at or below the available usable bit rate on the network. Although latency may be introduced, the storage of transmitted media provides the ability to extend the useful range and/or capacity of the network when conditions on the network otherwise make live communication impossible or impractical.

Abstract: An apparatus for transferring a complete copy of media designated as time sensitive over a network. The apparatus includes a sending node including a network ascertaining element configured to ascertain 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 the 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 transmitter at the sending node generates and transmits a reduced bit rate representation of the media designated as time-sensitive. The transmitting node is also configured to receive receipt reports from the receiving node that identify the received reduced bit rate representation of the media.

Abstract: A communication device configured to receive messages containing media over a communication network and to receive locally created messages containing media created using the communication device. The device also includes a time-shifting buffer to store in a time-based format the media contained in both the messages received over the communication network and the locally created messages. The time-shifting buffer enables on the communication device to either (i) render the media received over the network in a near real-time mode; or (ii) render both the media received over the network and the locally created media in a time-shifted mode by retrieving the stored media from the time-shifting buffer. The communication device also includes a message management system, which enables the communication device to transition the rendering of the media between the time-shifted mode and the near real-time mode without interrupting the ongoing storage of media of received messages into the time-shifting buffer.

Abstract: A method for enabling communication when network connectivity is reduced or lost during a conversation and for resuming the same conversation when connectivity improves.

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.
