    摘要: A system (10) includes a packet-switched network (12). A plurality of telephones (21-26) are each coupled to the network. A call manager server (31) is also coupled to the network, in order to interact with the telephones to implement telephony functions. Each of the telephones has the capability to act as an independent network client, by using Internet-compatible protocols to communicate directly with a resource server, without the participation or even the awareness of the call manager server. The resource server may be a local server (32) coupled directly to the network, or a remote server (66-68) coupled to the network through some other network, such as the Internet (52).

    摘要: Methods for concealing audible distortions resulting from changes in jitter buffer size include receiving an audio stream, storing the audio stream in a jitter buffer, and determining a pitch period associated with the audio stream. To expand the jitter buffer, a method includes inserting additional audio data that has a duration corresponding to an integer multiple of the pitch period into the audio stream. To contract the jitter buffer, a method includes removing a portion of the audio stream having a duration corresponding to an integer multiple of the pitch period.

    摘要: Various aspects of an interactive multimedia system and associated methods. In general, the multimedia system employs central and peripheral hubs that function to provide services to a plurality of clients of a call manager server, or manager subsystem. The hubs and subsystem cooperate to serve requests originating in the plurality of clients. The client-server-client architecture allows for distributed processing and resource management. Redundant connections between the various network subsystems and hubs provide survivability. Each subsystem or hub is provided with the ability to initialize or recover from systemic errors, thereby distributing initialization and recovery. Certain of the distributed resources are capable of being managed from other subsystems, thereby allowing sharing of the resources. An open numbering plan allows efficient call treatment of dialed numbers. Call processing is sharable between multiple manager subsystems. Finally, an iterative process is employed to ensure that calls routed through the network travel the shortest possible path.
