Abstract: A device with dynamically tunable heterogeneous latencies includes an input port configured to receive a packet via a network, and a processing module configured to determine multiple values corresponding to a number of qualifying parameters associated with the packet. The processing module may use the values to generate a selector value and may allocate a latency mode to the packet based on the selector value.

Abstract: A video processing system located at a remote location such as a TV broadcasting station or an Internet media server stores a plurality of video elements at that are delivered to a viewing system located at a viewer's premises. The video processing system is capable of receiving a selection request comprising two or more video elements or subsets thereof, wherein the subsets are regions of interest or portions of the corresponding video elements. The video processing system constructs a custom video by combining them based on the viewer' selection and using the region of interest that are provided, and forwards the custom video to the viewing system. Billing based on record of usage is also supported for the custom video.

Abstract: Aspects of geotagged communications are described herein. In one embodiment, a data unit including a geotag field is received over an ingress port of a network component. In turn, the network component may determine a path for forwarding the data unit to a location associated with the geotag field and with reference to a forwarding decision index. The path may include a least distance hop or a least distance route for forwarding or routing the data unit. With reference to the forwarding path, the network component may identify an egress port for forwarding the data unit. The network component may also forward the data unit over the egress port. According to other aspects, geolocation data may enable a network component to implement geotag-based virtual local area networks, geotag-based multiprotocol label switching, geotag-based fault detection and isolation, or geotag-based firewalls and fencing in wired routers or switches, for example.

Abstract: A video layer effects processing system which receives normal video and special effects information on separate layers has been presented. The system selectively mixes various video layers to transmit a composite video signal for a video display such as a television, or a virtual reality system. Special effects include spotlights, zooming, etc. Additional special effects such as shaping of objects and ghost effects are created by masking and superimposing selected video layers. The selective mixing, for example, to enable or disable, strengthen or weaken, or otherwise arrange special effects, can be directed from a remote source or locally by a user through real-time control or prior setup. The video layer effects processing system can also be incorporated into a set-top-box or a local consumer box.

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.

Abstract: A video processing system includes at least one video source, a region selecting unit, a subtracting unit and a display unit. The region-selecting unit selects the user-defined region of interest from the video source. The subtracting unit subtracts the required region, selected by the region selecting unit. The output of the subtracting unit is provided to the display unit, which displays the required output. In one embodiment, when video data is received from a plurality of video sources, the selecting of user defined regions of interest from the video sources is supported. The region subtracting unit can be used to subtract the required region of interest from video data and it is displayed on the display unit. In other embodiments of invention, the display unit displays on overlay of two unrelated video streams.
