    • A media gateway to distribute network services and content throughout a home or residence is described. Generally, the media gateway includes a structured wiring panel, a services switch mounted within the structured wiring panel to receive network services from one or more network service providers, and to distribute the network services to a number of data outlets located at the residence. The media gateway may also include one or more patch panels mounted within the structured wiring panel to provide connectivity between the services switch and the data outlets, and an uninterruptable power supply (UPS) mounted within the structured wiring panel to supply backup electrical power to the services switch and/or one or more of the plurality of data outlets in the event of a main power failure.
    • 描述了在家庭或住宅内分发网络服务和内容的媒体网关。 通常,媒体网关包括结构化布线面板,安装在结构化布线面板内的服务开关,用于接收来自一个或多个网络服务提供商的网络服务,并将网络服务分发到位于住所的若干数据出口。 媒体网关还可以包括安装在结构化布线面板内的一个或多个接线板,以提供服务开关和数据出口之间的连接;以及安装在结构化布线面板内的不间断电源(UPS),以将备用电力提供给 服务交换机和/或在主电源故障的情况下的多个数据出口中的一个或多个。

    • Digital packets, defined by a sync byte and then 130 MPEG2 compressed QPSK signal bytes, from a satellite transponder are reformatted prior to transmission to television receivers in apartments in a building wired to distribute video signals. A side byte between such sync and signal bytes in each packet indicates (a) any QPSK packet uncorrectable error and (b) processing information which allows automatic reconfiguration at the settop box. Additional FEC bytes correct to 8 errors within a MPEG2QPSK packet. The system removes the FEC bytes and reframes the MPEG2QPSK packets into a superpacket by converting a first number of the MPEG2QPSK packets to a second number of MPEG2QAM packets. An added sync byte indicates the beginning of each such MPEG2QAM packet. The system adds side data bytes including any uncorrectable errors in each MPEG2QPSK packet and adds a new, less complicated FEC to each MPEG2QAM packet. The system modulates and upconverts the bytes in each MPEG2QAM packet and passes them through a cable plant constructed to receive modulated QAM bytes (or NTSC signals) which are demodulated at the settop box. The additional FEC bytes correct to 8 errors within a MPEG2QAM packet and are then removed. The superpacket is deframed to obtain the MPEG2QPSK packets. After finding a television channel, the side bytes are processed to determine the frequency location of the other channels in the apartment receivers and the existence of uncorrectable errors. The MPEG2QAM bytes are decompressed and encoded to reproduce the television images in the apartment receivers.
    • 来自卫星转发器的同步字节和130个MPEG2压缩的QPSK信号字节定义的数字分组在传输到有线分配视频信号的建筑物的公寓中的电视接收机之前被重新格式化。 每个分组中的同步信号字节之间的边字节表示(a)任何QPSK分组不可校正错误和(b)允许在机顶盒自动重新配置的处理信息。 附加的FEC字节校正为MPEG2QPSK 分组内的8个错误​​。 该系统通过将第一数量的MPEG2 QPSK分组转换为第二数量的MPEG2 QAMAM分组来去除FEC字节并将MPEG2 QPSK分组重构为超分组, / SUB>数据包。 添加的同步字节表示每个这样的MPEG2 QAM 分组的开始。 该系统在每个MPEG2QPSK分组中添加包括任何不可校正错误的边数据字节,并且向每个MPEG2 QAM 分组添加新的较不复杂的FEC。 系统对每个MPEG2 QAM分组中的字节进行调制和上变频,并将它们通过构造成接收在机顶盒解调的调制QAM字节(或NTSC信号)的电缆设备。 附加FEC字节校正到MPEG2QAM 分组内的8个错误​​,然后被去除。 超级分组被去帧以获得MPEG2 QPSK 分组。 找到电视频道后,处理边字节以确定公寓接收机中其他频道的频率位置以及不可校正错误的存在。 对MPEG2QAM字节进行解压缩和编码以再现公寓接收机中的电视图像。
