The present invention controls delivery of television content to conserve network resources based on whether the television content is being viewed on a television monitor. A television gateway may monitor a viewer's interactions with the television gateway to determine whether the television content is being viewed at the associated television monitor, or detect whether the television monitor is on or off. Upon determining that the viewer is not viewing the television content, various actions can be taken to conserve network resources.

Security information such as fixed or dynamically received camera location information, laser signature information, timestamp information, and network information, may be used to secure the transport and storage of surveillance video. Where the surveillance video is to be transported on a communication network, the round trip time from a video data storage server to the surveillance camera and back to the video data storage server may be monitored and periodically added to the secured video data. By checking to see whether the round trip time has changed, it may be possible to determine whether the video has been tampered with. The secured video data may also be transported over two or more paths on the network to two or more video data storage servers so that redundant copies may be stored at different primary locations. By comparing copies of the data, alteration of one of the copies may be detected.

Method and apparatus for secure transport and storage of surveillance video

This invention provides a system, method and apparatus for managing congestion on heterogeneous network communication links, the first communication link and second communication link being heterogeneous with respect to each other. The system, method and apparatus including a routing decision module, the routing decision module evaluating a queue of information packets scheduled for transmission across the first communication link to determine whether to generate a command signal to route a portion of information packets over the second communication link. The system, method and apparatus may further include a communication link threshold module, the communication link threshold module storing threshold limit values corresponding to a first communication link technology of the first communication link.

The invention provides for a system, method, and device for using the existing copper loop plant of twisted pair wiring for data communication by using a plurality of pairs in a cable bundle of twisted pair for the downstream data direction simultaneously, as if the plurality of twisted pair in the cable bundle were a broadcast medium. Between an individual subscriber's access pair and the cable bundle, an aggregation device is used to combine all received signals from the plurality of twisted pairs in the cable bundle and to make the entire downstream bandwidth of the plurality of pairs available to the subscriber.

Information may be extracted from an array of relatively low sensitivity hazardous material sensors deployed, for example within a population center, by collecting identification information, such as video data, RFID data, proximity data, and IR data along with the hazardous material sensor reading. The identification information may then be used to identify objects in the vicinity of the hazardous material sensor at the time the reading was taken. By using identification data to identify an object, and then correlating sensor data readings for that object with other sensor data readings for the same object, as identified using previously collected identification information, a statistically more significant reading may be obtained for that particular object than would be obtainable by any one particular hazardous material sensor. Optionally the proximity of the object to the sensors may be used to weight the readings from the sensors.

A protection arrangement for a telephone subscriber line interface circuit is disclosed. The arrangement is particularly useful for protecting an electronic telephone set from over-voltage and over-current fault conditions. The arrangement provides a FET that operates in saturation mode to connect an office battery to the subscriber line under normal operation. The FET also provides isolation capabilities for protecting the line circuit from an over-current condition on the subscriber line. Over-voltage protection is provided by way of an isolation relay between the line circuit and the subscriber line. Both the FET and isolation relay are operated by a controller that uses timers in the methods of over-voltage and over-current protection that it performs. A further capability of the arrangement is that it resets itself after the fault condition has ended. This feature is particularly useful in the case of fault conditions of short duration.

In the occurrence of a data modem establishing a data communication session over a telephone line, a method is disclosed for detecting the modem and subsequently reducing the telephone line current. Initially, when a new telephone call is begun, the line current is set as normal to a current sufficient to power a standard telephone handset. Subsequently, using modulation detection techniques, it is determined whether a modem data session has been initiated on the particular telephone line. If such a session has begun, the normal current level on the telephone line is unnecessary since data modems are locally powered. To minimize wasted power and reduce thermal problems caused by the modem dissipating the excessive current, a reduced current is set on the telephone line. This reduced current is either a predetermined modem current level or a minimum allowable current for the particular telephone line, as calculated within the line interface circuit.

Device which reduces central office battery current during modem connections

An improved electrical interconnection between a first circuit board and a second circuit board is provided. In one embodiment, the first circuit board has a substantially rigid circuit portion having a plurality of circuit layers, including a first signal layer, and a first interconnection portion, including the first signal layer, for mating with a second interconnection portion of the second circuit board. The first circuit board also includes a flexible portion, including the first signal layer, for connecting the substantially rigid circuit portion to the first interconnection portion. The flexible portion allows the first interconnection portion to be oriented substantially perpendicular to the substantially rigid circuit portion such that a mating of the first interconnection portion with the second interconnection portion results in a substantially orthogonal electrical interconnection arrangement between the first circuit board and the second circuit board.

A technique for connecting signal tracks within a multi-layer substrate is disclosed. In one embodiment, the technique is realized by providing an opening in a substrate and fitting an inserted component into the opening. The inserted component comprises a dielectric block mounted to a lead frame. The lead frame is conductive such that a signal layer formed between the inserted component and the substrate connects signal tracks on multiple signal layers of the substrate.
