摘要： Optical networks as defined by the IEEE 802.3ah standard suffer from Stimulated Raman Scattering (SRS) that causes data transmission at a first optical wavelength to interfere with broadcast video transmission at a second optical wavelength in single mode optical fibers. The problem is exacerbated when data is not being transmitted across the network; and instead, an idle pattern transmission is being transmitted in order to keep the network synchronized. The repetitive nature of the idle pattern transmission leads to the SRS optical interference effect. This optical interference effect is mitigated when countermeasures are implemented to modify the idle pattern transmissions or to transmit random data in place of the idle pattern transmissions.

摘要： Subscribers to Internet Protocol TV services usually complain about one key characteristic—the additional delay digital video introduces when subscribers change channels, especially when subscribers “channel surf.” The problem is traced to at least three sources of delay in a convention Internet Protocol video deployment system. The channel changing delay can be minimized by caching video packets for the most likely next channel in a buffer in anticipation of a television subscriber changing channels and/or by having an adaptable buffer length in the set top box.
摘要翻译：互联网协议电视服务的订阅者通常会抱怨一个关键特征 - 当用户改变频道时引入额外的延迟数字视频，特别是当用户“频道冲浪”时。在常规互联网协议视频部署系统中，该问题至少被追溯到三个延迟来源。通过在预期电视订户改变频道和/或通过在机顶盒中具有适应性缓冲区长度的情况下缓存缓冲器中最可能的下一频道的视频分组，可以最小化频道改变延迟。

摘要： The invention is directed to an improved scrambler capable of self-calibrating output signals. In one embodiment, the scrambler provides an encoded signal along separate signal pulses. A portion of one signal is made to correspond to a portion of another signal to thereby self-calibrate the signals. Also, portions of the incoming video signal are forced to correspond with internally generated voltage level signals.

摘要： The filling of a syringe can be performed at a faster rate using a filling sequence which expels air from the fill tube before filling the syringe. A similar method is used when changing contrast containers during a filling sequence to ensure that all the air is expelled from the fill tube before filling resumes with the new contrast container. Additionally, by including a contrast container holder that is affixed to an injector head and holds the container near the syringe tip, the filling sequence can be accomplished without requiring the operator to hold the contrast container during the sequence.
摘要翻译：注射器的填充可以使用在填充注射器之前从填充管排出空气的填充顺序以更快的速率进行。当在填充顺序期间改变对比剂容器时，使用类似的方法以确保在用新的对比容器填充恢复之前所有空气都从填充管排出。此外，通过包括固定到注射器头部并将容器保持在注射器末端附近的造影剂容器保持器，可以实现填充顺序，而不需要操作者在顺序期间保持造影剂容器。

摘要： An apparatus (7) for switching from a first pilot signal and a second pilot signal on a system transporting a plurality of signals. A tuner (30) receives the signals and provides an output signal to a loop compensation circuit (26). The tuner includes a bandpass filter (22) for removing signals other than the selected pilot signal from the output of the tuner. The output of the bandpass filter is provided to a detector circuit (24, 25). The output of the detector is compared with a reference signal (28) by the loop compensation circuit (28). A microcontroller (39) sends a tuning command to the tuner which causes the tuner to switch from tuning to the first pilot signal to tuning to the second pilot signal and also sends a new reference voltage to the loop compensation circuit. Thus, if the input signal changes from analog to digital modulation on the pilot channel, the set-point, or target level of the reference signal, will automatically change to provide the correct value for operation of the circuit. The microcontroller may change the selected pilot signal based upon a command in the input signal or upon an operator command, such as by setting a switch (not shown).
摘要翻译：一种用于在传输多个信号的系统上从第一导频信号和第二导频信号切换的装置（7）。调谐器（30）接收信号并向环路补偿电路（26）提供输出信号。调谐器包括带通滤波器（22），用于除去来自调谐器的输出的所选择的导频信号之外的信号。带通滤波器的输出被提供给检测器电路（24,25）。通过环路补偿电路（28）将检测器的输出与参考信号（28）进行比较。微控制器（39）向调谐器发送调谐指令，使得调谐器从调谐转换到第一导频信号以调谐到第二导频信号，并且还向环路补偿电路发送新的参考电压。因此，如果输入信号在导频信道上从模拟到数字调制变化，则参考信号的设定点或目标电平将自动改变，以为电路的运行提供正确的值。微控制器可以基于输入信号中的命令或操作员命令来改变所选择的导频信号，例如通过设置开关（未示出）。

摘要： An apparatus and method for saving client/server socket state information to recoverable storage (disk, nonvolatile cache, tape, or other storage). After a server failure, upon recovery the server will be able to send out RSTs to inform remote clients of the server failure. The result is faster recovery for the remote clients that will be able to clean up and restart sockets/transactions as soon as the server side becomes active rather than waiting for a long timeout condition or for programmed or human intervention on the client/network side.

摘要： The present invention is directed to an inversion scrambler and unscrambler having pseudo-randomly controlled polarity-reversing switches to invert and re-invert, respectively, an audio signal so as to restrict the intelligent dissemination of the audio signal. To improve security of the scrambled signal, the audio signal is concealed prior to scrambling. Concealment includes clamping the original audio signal to a predetermined value and optionally offsetting this clamped signal prior to scrambling. The concealed signal is scrambled by inverting contiguous portions of the signal at pseudo-random intervals, accomplished by a polarity-reversing switching network controlled by a pseudo-random code generator. Upon unscrambling, artifacts will appear at the inversion points of the unscrambling signal, due to bandwidth limitations inherent in any transmission path. To mask the artifacts, track-and-hold circuitry is used to sample the unscrambled audio signal waveform level just prior to the artifact and hold this level throughout the short period when the artifact would occur.
摘要翻译：本发明涉及一种具有伪随机控制的极性反转开关的反相扰频器和解扰器，以分别反转和重新转换音频信号，从而限制音频信号的智能传播。为了提高加扰信号的安全性，音频信号在加扰之前被隐藏。隐藏包括将原始音频信号钳到预定值，并可选地在加扰之前抵消该钳位信号。隐藏的信号通过以由伪随机码发生器控制的极性反转交换网络的伪随机间隔来反转信号的相邻部分来加扰。在解扰乱时，由于任何传输路径中固有的带宽限制，伪扰信号将出现在解扰信号的反转点。为了掩盖伪像，跟踪和保持电路用于在伪像之前对未加扰的音频信号波形级进行采样，并在发生伪影的整个短时间内保持该电平。
