  • Publication number: 20080008194
    Abstract: A system (30) and network bypass device (28) for bypassing application specific data traffic past a network routing device. The network routing device routes data traffic between a first network, such as the Internet or wide-area network (WAN) and a second network, such as a residential network or other local area network (LAN). The network bypass device routes data traffic associated with various standard application devices in the LAN from the first network to the network routing device, for routing to the standard application devices. The network bypass device also routes data traffic associated with various application specific or bypass application devices from the first network to the bypass application devices in such a way that the data traffic bypasses the network routing device. In this manner, the flow of data traffic intended for the bypass application devices is not restricted by the network routing device and its security elements.

  • Publication number: 20050243801
    Abstract: An inventive Network Address Translation (“NAT”) device and method for automatic port forwarding whenever said NAT device detects that only one Local Area Network (“LAN”) IP address has been leased by its DHCP server is disclosed. Under this condition, the inventive NAT device automatically configures all ports to be forwarded (except those that may be reserved for applications running in the inventive NAT device), to the single leased LAN IP address. This minimizes, if not eliminates, the conventional address configuration required when a NAT device is added to an existing network.

  • Publication number: 20030028894
    Abstract: An access node that is deployable at a distance from a cable company head-end or a telephone company central office serves residential and business subscribers within a small geographical area. The access node provides interoperability between and across communications links and protocols, thereby providing a modular, configurable access point for both business and residential users that enables the service provider to tailor its services for each user in a cost-effective manner. The access node includes modular interfaces to multiple communications links and protocols on its network side and modular interfaces to multiple communications links and protocols on its user or access side. A switch/router connects the outputs of the two interfaces together and aggregates traffic to the network while simultaneously partitioning traffic to the users to the appropriate connections.

  • Patent number: 5606612
    Abstract: A method and apparatus for scrambling an original analog video signal samples predetermined portions of the original video signal at a first rate and stores the sampled portions of the original video signal within a memory device. The stored video signal is read out of the memory device at a second rate, which is less than the first rate, to produce a time expanded scrambled video signal. A predetermined code is inserted into the time expanded scrambled video signal which is then converted into an analog scrambled video signal and transmitted through a channel. A method and apparatus for descrambling the scrambled video signal to produce a reconstructed video signal samples the scrambled video signal at the second rate, stores the sampled scrambled video signal into a memory and reads the sampled scrambled video signal out of the memory at the first rate.

  • Patent number: 5136411
    Abstract: A CATV system uses a single single-mode optical fiber for transmitting a composite optical signal containing television signals in different frequency channels for a plurality of subscriber terminals from a headend terminal to a distribution terminal, and converts the transmitted signals at the distribution terminal into electrical signals for distribution to a plurality of subscriber terminals over a plurality of coaxial cables. The distribution terminal further receives electrical service request signals from each of the plurality of subscriber terminals, and converts each received service request signal into an optical service request signal for transmission to the headend terminal over the same single-mode optical fiber as used from transmitting the composite optical signal. Wavelength-division multiplexer/demultiplexers couple the optical fiber to the headend terminal and the distribution terminal to enable bidirectional transmission.

  • Patent number: 5046138
    Abstract: Apparatus and a method are provided for aligning an analog laser transmitter. Operational characteristics of the laser are determined. These characteristics are used to derive the power level required of a communication signal to properly modulate the laser for communication across an optical fiber. The magnitude of an input communication signal is then adjusted to the derived level, and maintained at this level for proper modulation. The alignment is performed upon the replacement of laser components in the field. The alignment may also be periodically effected to compensate for normal degradation of laser components over time.

  • Patent number: 4815129
    Abstract: An encrypted video distribution system includes a signal originating station which distributes television signals in a format unrecoverable by a standard television receiver. In particular, the normally occurring vertical and horizontal synchronizing pulses are deleted and, optionally also, video information is selectively inverted about a voltage reference potential intermediate the black and white levels. To permit synchronization restoration, a keying pulse is transmitted once each video field, and a synchronizing digital code burst transmitted once each frame--all at a fixed, predetermined intra-frame timed relationship. At each authorized subscriber location, the keying pulse and digital code burst are employed to lock a receiver frame clock which derivatively gives rise to all requisite reception-permitting synchronizing pulses. The transmitted information also contains information sufficient to restore the inverted video program content.
