Abstract: Systems and methods for reducing bit rates by replacing original texture in a video sequence with synthesized texture. Reducing the bit rate of the video sequence begins by identifying and removing selected texture from frames in a video sequence. The removed texture is analyzed to generate texture parameters. New texture is synthesized using the texture parameters in combination with a set of constraints. Then, the newly synthesized texture is mapped back into the frames of the video sequence from which the original texture was removed. The resulting frames are then encoded. The bit rate of the video sequence with the synthesized texture is less than the bit rate of the video sequence with the original texture. Also, the ability of a decoder to decode the new video sequence is not compromised because no assumptions are made about the texture synthesis capabilities of the decoder.
Abstract: A broadband powerline communication system makes use of knowledge of the spectrum characteristics of a local radio environment in order to improve system performance. A determination is made of the spectrum characteristics of a radio environment in the vicinity of the broadband powerline communication system that is transmitting data on modulated carrier frequencies. In order to avoid interference, certain ones of the carrier frequencies otherwise used by the broadband powerline communication system may be selectively masked based on the determination. The spectrum characteristics may be determined 1) in advance and used to compile a configuration database comprising frequency masking parameters; 2) by monitoring the local radio environment using the transmitter/receiver nodes of the system; or 3) based upon receipt of an indication from a conflicting user that the user is experiencing interference. Various combinations of these spectrum characteristic determination techniques may also be used.

Abstract: A method and apparatus for performing traffic engineering, e.g., allocating bandwidth, on a wireless access network are disclosed. For example, the method determines a number of subscriber stations (SSs) that a Base Station (BS) is capable of supporting in accordance with at least one performance objective for voice traffic, wherein the at least one performance objective for voice traffic comprises a type of codec. The method then allocates bandwidth by the base station in accordance with the number of subscriber stations that the base station is capable of supporting.

Abstract: Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.
Abstract: Network presence is used to assign a worker to a task. In today's networked environment, workers may be remotely located but still accomplish tasks. As long as workers have network access, the workers may be assigned tasks for completion. As tasks are completion, the network presences of the workers are determined, and the tasks may be assigned based on the network presences.
Abstract: Network resources for a call are allocated. The network resources for the call are reserved based on a reservation. The network resources are reserved before any one network resource is committed. If the call is confirmed, then the network resources are committed.

Abstract: A system and method for securing communications between a plurality of users communicating over an optical network. The system utilizes a fixed or tunable source optical generator to generate entangled photon pairs, distribute the photons and establish a key exchange between users. The distribution of entangled photon pairs is implemented via at least one wavelength selective switch.
Abstract: In one embodiment, a semantic classifier input and a corresponding label attributed to the semantic classifier input may be obtained. A determination may be made whether the corresponding label is correct based on logged interaction data. An entry of an adaptation corpus may be generated based on a result of the determination. Operation of the semantic classifier may be adapted based on the adaptation corpus.

Abstract: Mass amounts of information, such as entire libraries of songs or movies, for example, may be stored locally near end-users, and this information may be accessed and reproduced in response to commands received from a transmitting station via a network. When a radio or television station desires to transmit a song or movie, for example, the radio or television station can, rather than transmitting the entire song or movie, merely transmit a command for reproducing the song or movie. An end-user's performance reproduction device, such as an enhanced radio or a television set, then accesses and reproduces the locally stored song or movie. Since the radio or television station need not transmit the entire performance, network traffic can be significantly reduced. The performance reproduction device may actively request information from the radio or television station when fresh or additional information is needed.
Abstract: Certain exemplary embodiments can comprise a method, which can comprise automatically providing content to an information device from a content distribution node of a plurality of content distribution nodes. The information device can be adapted to send a request for the content from the first content distribution node utilizing an Internet Protocol (IP) address of the content distribution node.

The common mobility management protocol can be used by existing and future multimedia applications (MA's) to support mobility management for messaging among mobility management authentication function (AuF), home location function (HLF) and visitor location function (VLF) databases/servers, and the corresponding multimedia application functional entities (MAFEs) of the multimedia applications (MA's). The common mobility management protocol may replace, act in concert with or in sequence with existent interworking protocols for the various multimedia applications. Reference point architectures, functional characteristics, features, and capabilities of the protocol are described including call flows and message syntax. The disclosure presents the scope of Q.5/16 and how H.MMS.1 (H.323 Mobility), H.MMS.
Abstract: A telephone network voting system receives telephone ballots cast by voters by dialing a telephone number. The telephone number is dialed by voters spread over a large geographic area. The voting calls are routed to points of presence local to or otherwise identified with the caller by using the caller's ANI or other originating number identification. The points of presence then accumulate votes and periodically forward tallies to a centralized location over a data network. Instructions may be transmitted from the centralized location to the points of presence.

Abstract: A special rendering mode for the first few seconds of play out of multimedia data minimizes the delay caused by pre-buffering of data packets in multimedia streaming applications. Instead of pre-buffering all incoming data packets until a certain threshold is reached, the streaming application starts playing out some of the data packets immediately after the arrival of the first data packet. Immediate play out of the first data packet, for example, results in minimum delay between channel selection and perception, thereby allowing a user to quickly scan through all available channels to quickly get a notion of the content. The immediate play out is done at a reduced speed.
Abstract: A call between a calling party and a called party, one or both of whom may be subscribers to Internet Telephony (IT) services, commences upon the receipt of a call dialed by the calling party to the Plain Old Telephony Service (POTS) number associated with the calling party. A first hub receives the call and routes it to the called party if that party is not an IT services subscriber that is currently on line. If the called party is an IT services subscriber that is on-line, the call is received at an Internet Services Provider serving the called party. The ISP converts the call to an IT format if the call is not already in that format and thereafter delivers the call to the called party.
