Abstract: A gateway network device may establish secure connections to a plurality of remote network devices using tunneling protocols to distribute to the remote network devices multimedia content received from one or more content providers. The consumption of the multimedia content may originally be restricted to local network associated with the gateway network device. The secure connections may be set up using L2TP protocol, and the L2TP tunneling connections may be secured using IPSec protocol. Use of multimedia content may be restricted based on DRM policies of the content provider. DRM policies may be implemented using DTCP protocol, which may restrict use of the multimedia content based on roundtrip times and/or IP subnetting. Each content provider may use one or more VLAN identifiers during communication of the multimedia content to the gateway network device, and the gateway network device may associate an additional VLAN identifier with each secure connection.

Abstract: A central entity and/or a remote device in a communication system are designed to address the problem of maintaining upstream synchronization in the remote device after loss of the downstream signal. One issue of particular importance is maintaining upstream transmissions from the remote device in an S-CDMA (or perhaps S-TDMA) mode that do not degrade performance of the communication system via poor upstream timing or a need for re-ranging. By providing novel functionality at the central entity for synchronizing first and second downstream signals and/or by providing novel functionality at the remote device for determining a symbol clock offset between a first terminated downstream signal and a second re-acquired downstream signal, embodiments of the present invention facilitate maintenance of synchronization through the loss of the downstream signal, thereby minimizing the need for re-ranging and avoiding poorly timed upstream bursts.

Abstract translation: 通信系统中的中央实体和/或远程设备被设计为解决在丢失下行信号之后维护远程设备中的上行同步的问题。 一个特别重要的问题是在S-CDMA（或可能的S-TDMA）模式中维护来自远程设备的上行传输，其不会通过差的上行时序或重新测距的需要来降低通信系统的性能。 通过在中央实体提供用于同步第一和第二下游信号的新颖功能和/或通过在远程设备处提供新颖的功能来确定第一终止的下行信号和第二重新获得的下行信号之间的符号时钟偏移， 本发明便于通过丢失下行信号来维持同步，从而最小化对重新测距的需要，并避免不良定时的上行脉冲串。

Abstract: A method and apparatus is disclosed to compensate for impairments within a data converter such that its output is a more accurate representation of its input. The data converter includes a main data converter, a reference data converter, and a correction module. The main data converter may be characterized as having the impairments. As a result, the output of the main data converter is not the most accurate representation of its input. The reference data converter is designed such that the impairments are not present. The correction module estimates the impairments present within the main data converter using its output and the reference data converter to generate corrections coefficients. The correction module adjusts the output of the main data converter using the corrections coefficients to improve the performance of the data converter.
