Abstract:
Presented herein are systems and methods for global positioning system based secure access. A request for access to a computer network is received. A determination is made whether a mobile terminal is within a predetermined location. If the mobile terminal is within the predetermined location, access is granted. If the mobile terminal is outside of the predetermined location, access to the computer network is denied.
Abstract:
A method of filtering data packets in a network device is disclosed. An incoming packet is received from a port and the incoming packet is inspected and packet fields are extracted. The incoming packet is classified based on the extracted packet fields and action instructions are generated. The incoming packet is then modified based on the action instructions. Further, the inspection and extraction includes applying inspection mask windows to any portion of the incoming packet to extract programmable packet fields.
Abstract:
A method for establishing a virtual channel between network devices is disclosed. In the case of a local network device establishing a virtual channel with a remote network device, a virtual channel request message is sent from the local network device to the remote network device. A virtual channel acknowledgement message and a remote capability list are received and a virtual channel resume message and a local capability list are sent. The virtual channel is then enabled. In the case of a remote network device establishing a virtual channel with a local network device, a virtual channel request message is received from a local network device by a remote network device. A virtual channel acknowledgement message and a remote capability list are sent and a virtual channel resume message and a local capability list are received. The virtual channel is then enabled.
Abstract:
A method for selectively controlling the flow of data through a network device is discussed. The network device has a plurality of ports, with each port of the plurality of ports having a plurality of priority queues. Congestion at one priority queue of the plurality of priority queues is detected and a virtual channel message is sent to other network devices connected to the network device causing data destined for the one priority queue to be halted. After the congestion at the one priority queue has abated, a virtual channel resume message is sent to the other network devices.
Abstract:
Presented herein are systems and methods for integrating secure identification logic into cell phones. A registration is received, wherein said registration includes an identifier identifying a mobile terminal. Information is transmitted to the mobile terminal, wherein a password is a function of the information.
Abstract:
A network component for processing a packet can include at least one first storage unit configured to store a packet field value within the packet, at least one second storage unit configured to store at least one set of a plurality of range values, and an action implementation unit configured to implement at least one action when the packet field value is within the plurality of range values.
Abstract:
A set top box circuitry receives television channels, receives a viewer input, constructs a composite video from the television channels using the viewer input and forwards the composite video for display. The viewer input identifies a selection of at least two of the television channels and another selection of portions or all of the at least two of the television channels. The viewer input carries definitions of the selected portions that are typically, dimensions of the selected portions, shapes of the selected portions and locations of the selected portions when revealed on a display. The set top box circuitry constructs the composite video by combining the selected portions using the definitions. The set top box circuitry maintains a usage record of the television channels that are not free to use and forwards the usage record to a charging system that uses the usage record to generate an invoice.
Abstract:
A video karaoke system comprises a first video source and a second video source, providing input to a mixing unit. The mixing unit provides a composite output that includes at least a portion of the video data from the first video source and a portion of video data from the second video source. The output of the mixing unit is configured to display on a display unit. The present invention also provides a method of mixing video data from plurality of video sources providing a combined output. The method comprises providing a plurality of video sources, and a region selecting unit selecting regions of interest from the plurality of video sources. The selected regions of interest from the plurality of video sources are then mixed to provide a combined output video image.
Abstract:
Spotlighting and other special effects are applied by processing circuitry in real time to received video streams. Effects tracking may be applied to fixed regions or moving regions or objects of interest. Viewers interact via conventional remote controls and other user interfaces to set effect parameters. Other special effects employed include zooming, masking, etc. and can be used to enhance one or more spotlight effects. Televisions, set top boxes and media players house the underlying circuitry. Effects are applied to layered and non-layered video streams to form layered and combined video stream output. Video outputs also deliver effect parameters such as region of interest location along with a video stream. Such effect parameters assist in the downstream application of dynamic effects.
Abstract:
A multicast call processing unit receives a request from a requester, determines if the request is associated with a multicast function, identifies a plurality of destinations defined by the multicast function and establishes communication link between the requester and the plurality of destinations. In one embodiment, the call processing unit authenticates the plurality of destinations before establishing a communication link between them and the requester. If the request from the requester is not associated with the multicast function, then the call processing unit establishes a communication link between the requester and a single destination. In another embodiment, a supervisor manages the plurality of destinations.
