摘要： A conversion entity and method for converting higher-rate speech parameters into lower-rate parameters including dimmed excitation parameters. The conversion entity comprises a first decoder configured to produce a target excitation from the higher-rate parameters, based on a first fixed contribution and a first adaptive contribution. The conversion entity also comprises a second decoder configured to produce a second adaptive contribution, and configured to selectably operate in a first or a second mode. In the first mode, the second adaptive component is generated based on the first fixed contribution for a previous frame, while in the second mode, the second adaptive component is generated based on a second fixed contribution for the previous frame. The second decoder operates in the second mode in response to a rate reduction request. A processing module determines the dimmed excitation parameters for generation of the second fixed contribution for the current frame, based on the target excitation and the second adaptive contribution.

摘要： An echo cancellation device for reducing a magnitude of an echo occurring in a voice signal propagating in a channel of a communication system. The echo cancellation device is capable to selectively acquire an active operative mode and an inactive operative mode in response to a condition indicative of a level of echo present in the voice signal. In the active operative mode the echo cancellation device performs echo cancellation on the voice signal. In the inactive operative mode the echo cancellation device allows the voice signal to propagate without performing any echo cancellation.

摘要： The present invention provides a technique for determining which nodes are to provide various functions on traffic along a particular communication path. Generally, a communication path may include multiple nodes between which and through which traffic is routed. These nodes may include the communication terminals at either end of the communication path, as well as various types of routing nodes along the communication path. Each node will send to other nodes in the communication path information identifying the local functions it is capable of providing to the traffic carried in the communication path, and if available, remote functions capable of being provided to the traffic by other nodes in the communication path. Each node will receive from other nodes in the communication path information bearing on the remote functions. Each node will access criteria to determine whether any local functions should be applied to the traffic.

摘要： In methods and apparatus for processing a speech signals comprising a plurality of successive signal intervals, each signal interval containing no speech sounds is classified as a noise interval, and LPC coefficients are calculated for each noise interval based on the samples of that noise interval and on the samples of a plurality of preceding signal intervals. When noise intervals encoded using LPC coefficients calculated as described above are reconstructed, the subjectively annoying "swishing" or "waterfall" effects encountered in conventional LPC speech processing systems are reduced or eliminated.

摘要： The present invention provides for echo cancellation circuitry and variable rate encoding circuitry to cooperate with one another to effectively provide comfort noise in an effective and efficient manner. The echo cancellation circuitry will use far-end signals to generate estimated echo signals, which correspond to the actual echo signals appearing in near-end signals. The estimated echo signals are essentially subtracted from the near-end signals in an effort to remove the actual echo signals from the near-end signals. The echo cancellation circuitry will monitor any residual echo signals in the resulting processed near-end signals and provide residual echo control signals that are indicative of whether the residual echo signals should be replaced with comfort noise. The residual echo control signals are used at least in part by the variable rate encoding circuitry to determine the encoding rate to use for encoding different portions of the processed near-end signals.
摘要翻译：本发明提供了回波消除电路和可变速率编码电路，以便以有效和有效的方式彼此协作以有效地提供舒适噪声。回波消除电路将使用远端信号来产生对应于近端信号中出现的实际回波信号的估计回波信号。估计的回波信号基本上从近端信号中减去，以努力去除近端信号的实际回波信号。回波消除电路将监测所得到的经处理的近端信号中的任何残留回波信号，并提供指示残留回波信号是否应被舒适噪声替代的残余回波控制信号。残余回波控制信号至少部分地由可变速率编码电路使用，以确定用于对经处理的近端信号的不同部分进行编码的编码速率。

摘要： A process in a computer managed communication network such as the World Wide Web with user access via a plurality of data processor controlled interactive display stations and with a system for displaying documents, e.g. Web pages, transmitted to said display stations from locations remote from said stations which provides the user with the option of bookmarking a whole document or just sections of the document. Conventional means associated with one of said receiving display stations are provided for bookmarking selected transmitted documents, e.g. whole Web pages to thereby store at said receiving display station, direct links to the documents for future access. In combination with this function, the invention provides the document or Web page creator with the facility of defining one or more sections of the document or Web page as independent secondary documents together with the facility at the receiving display station for optionally bookmarking any secondary document to thereby store at the receiving display station, a direct link to the secondary document without accessing the basic transmitted document.
