    • A network content message placement management process is directed to the processing and management of messages in content displayed at a client computing device. A client computing device provides message placement configuration information to a network computing and storage provider. The network computing and storage transmits message placement requests to a content provider based on the message placement configuration information. The client computing device may subsequently directly or indirectly request content from the content provider. The content provided from the content provider may include one or more of the alternative messages provided in the message placement configuration information. Illustratively, the alternative messages may be included in place of other messages, such as advertisements, from third party message providers.

    • A multiplex optical transmission system for simultaneously transmitting and receiving a plurality of signals while minimizing external interference. The system includes a plurality of subgroup mixers wherein video signals, digital data signals, and audio signals are supplied to the respective subgroup mixers for being blocked into respective frequency ranges. The output of the subgroup mixers are, in turn, fed to a master mixer that produces a composite electrical signal therefrom. An optical transmitter is connected to the master mixer for converting the composite signal into an optical signal and transmitting the optical signal over a fiber optic cable. An optical receiver is connected to the other end of the fiber optic cable for receiving the optical signal and converting such back into a composite electrical signal. A de-multiplexer is coupled to the output of the optical receiver for separating the composite signal back into a composite video, data, and audio signals. A programmable optical patch board is interposed in the fiber optic cables for selectively connecting the optical signals to various receivers and transmitters.
    • 一种用于同时发送和接收多个信号同时最小化外部干扰的复用光传输系统。 该系统包括多个子组混合器,其中将视频信号,数字数据信号和音频信号提供给相应的子组混频器以被阻塞到相应的频率范围内。 亚组混合器的输出又被馈送到从其产生复合电信号的主混合器。 光发射器连接到主混频器,用于将复合信号转换成光信号,并通过光纤电缆传输光信号。 光接收器连接到光纤电缆的另一端,用于接收光信号并将其转换成复合电信号。 解复用器耦合到光接收机的输出端,用于将复合信号分离成复合视频,数据和音频信号。 可编程光接插板插入在光纤电缆中,用于选择性地将光信号连接到各种接收器和发射器。

    • A system for automatically optically switching fiber optic data signals between a plurality of input optical fibers (10, 11, 12, 13) and selective ones of a plurality of output fibers (56, 56a, 56b, 56c). The system includes optical detectors (14, 16, 18, 20) which are connected to each of the input fibers (10, 11, 12, 13) for converting the optic data signals appearing at the respective input fibers to an RF signal. A plurality of RF to optical signal converters (38, 40, 42, 44a, etc.) are arranged in rows and columns. The output of each of the optical detectors (14, 16, 18 and 20) are each applied to a respective row of optical signal converters (38, 40, 42, 44, etc.) for being converted back to an optical signal when the particular optical signal converter is selectively activated by a DC voltage. These optical signals are then applied via optical fibers (62) to optical detectors (58) which convert the optical signal back to an RF signal which is used for driving the ILDs ( 60). The ILDs (60), in turn, convert the RF signals back to optical signals without any mechanical switching either of the optical signals or the RF signals. The output fibers are connected to the output of the driving ILDs (60).
    • 一种用于在多个输入光纤(10,11,12,13)和多个输出光纤(56,56a,56b,56c)中的选择性光纤数据信号之间自动光学切换光纤数据信号的系统。 该系统包括连接到每个输入光纤(10,11,12,13)的光学检测器(14,16,18,20),用于将出现在各个输入光纤处的光学数据信号转换成RF信号。 多个RF至光信号转换器(38,40,42,44a等)以行和列布置。 每个光学检测器(14,16,18和20)的输出各自被施加到相应行的光信号转换器(38,40,42,44等),以便当转换回光信号时 特定的光信号转换器由DC电压选择性地激活。 然后,这些光信号经由光纤(62)被施加到光学检测器(58),光检测器将光信号转换回用于驱动ILD(60)的RF信号。 ILD(60)又将RF信号转换回光信号,而无需对光信号或RF信号进行任何机械切换。 输出光纤连接到驱动ILD(60)的输出端。
