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.

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.

Method and apparatus for generating video for a viewing system from multiple video elements

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.

Multiple logical channels for use in network devices

Disclosed herein is a method and system for multimedia viewership surveying of an end-user's set-top-box (STB). The multimedia information may be received from at least one satellite via a satellite receiver. The satellite receiver may convey the multimedia information to a service provider location. At the service provider location, a content server may receive a request for transmission of multimedia information. The request may be validated to determine whether the request is authorized. The method may also include monitoring channel requests, and channel viewing times. The method may also include recording and/or logging the channel requests and information associated with the requested program in a user log. The user log may be evaluated to facilitate targeted marketing of end-user subscribers based upon demonstrated television viewing habits.

System and method for multimedia viewership surveying

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.

Flow based congestion control

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.

Selectively applying spotlight and other effects using video layering

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.

Spotlight effect in video processing and playback

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.

Multiple virtual channels for use in network devices

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.

Video background subtractor system

A network component for processing a packet includes at least one first storage unit, at least one second storage unit, at least one third storage unit, and an action implementation unit. The at least one first storage unit is configured to store an initial bit value selected from within the packet. The at least one second storage unit is configured to store a bit action length value. The at least one third storage unit is configured to store an extracted bit value based upon the initial bit value and the bit action length value. The action implementation unit is configured to implement at least one action on a packet by using an action bit value to modify the extracted bit value.

Programmable packet field replacement based on a range technique

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.
