A system and a method are disclosed for detecting a multicast stream fault condition at a variety of points within a digital broadcast video distribution system. In addition, a method of seamless switchover from a primary to a redundant multicast stream is provided.

Fault tolerance and synchronous failover for broadcast video across the network

A method and system for QoS provisioning in broadband wireless mesh networks are disclosed. According to one embodiment, a computer-implemented method, comprises providing a dual mode mesh router having a plurality of radios, wherein the mesh router is used in a cell of a plurality of cells that covers a geographic region. The mesh router includes one or more WiMAX backhaul radios, one or more WiFi backhaul radios, one or more WiMAX access radios, one or more WiFi access radios, and three or more intra-mesh radios. Traffic is received at the dual mode mesh router. A minimum quality of service requirement is identified for the traffic. The traffic is routed via the one or more WiMAX backhaul radio when the minimum quality of service meets a predetermined value.

A respective novelty value is ascertained for each of multiple user-selectable contents. Each of the novelty values represents a level of newness of the respective user-selectable content in relation to the other user-selectable contents. A respective novelty decay value is calculated for each of the user-selectable contents as a decreasing function of the respective novelty value. A prioritization order of the user-selectable contents in respective prioritized positions on a web page is determined based on the novelty decay values.

Populating variable content slots on web pages

A system for multicast streaming of programs over a packet network includes a node having a processor that conditions a video bitstream such that packets containing an I-frame are located near program specific information (PSI) packets, the processor marking a random join point (RJP) in the video bitstream immediately preceding the I-frame and PSI packets, the node outputting the conditioned and marked video bitstream across the packet network. An edge device of the network includes a buffer that caches packets of the conditioned and marked video bitstream video starting at the RJP, and sends the cached packets to a client receiver.

System and method for fast start-up of live multicast streams transmitted over a packet network

Disclosed are apparatuses, computer readable storage media with instructions that carry out methods, and methods of (a) coding quantized transform coefficients as occur in image compression to form codewords, and (b) decoding a bitstream comprising the codewords. The coding combines a position identifying method to identify the relative position of clusters of consecutive non-zero-valued quantized transform coefficients, an amplitude event identifying method to identify amplitude events in the clusters of non-zero-valued quantized transform coefficients, and a coding method to code the position events, amplitude events, and signs of the amplitudes in the clusters. The coding method is particularly applicable to an ordered series of quantized transform coefficients where clusters are likely-to-occur.

Variable length coding for clustered transform coefficients in video compression

In a packet based multicast video streaming network, a method for minimizing delay in displaying video on a TV set in response to a viewer changing the channel is disclosed. For each live multicast video stream, one or more reference frames and corresponding compressed frames are temporarily stored in a memory in anticipation of the viewer switching to that particular program. When the viewer changes channels, the previously stored reference and compressed frames are immediately read from the memory and rendered for display on the TV. This eliminates the need to wait for the next available reference frame. In other words, this eliminates a temporary blank TV screen each time the channel is changed. Certain compressed frames are dropped and blank frames can be inserted in order to catch up to and synchronize with the live video broadcast. The particular frames to be dropped and the number of blank frames to be inserted is a function of the bandwidth limitation imposed by the last mile of the network.

A method and system for creating and deploying a mesh network are disclosed. In one embodiment, the method comprises providing a mesh router having a plurality of radios. The mesh router is used in a cell of a plurality of cells that covers a geographic region. Channels are assigned to the plurality of radios. The channels are selected from a plurality of channels to allow channel reuse throughout the plurality of cells.

The method is particularly applicable to a series of quantized transform coefficients where clusters are likely-to-occur.

A method and an apparatus to encode a series of quantized coefficients of a transform of a block of image data. The transform is such that 0 is the most likely coefficient amplitude and 1 is the next most likely coefficient amplitude. The method includes forming symbols (called events) from the series of quantized transform coefficients. An event is a run of none or more zero-valued coefficients followed by a run of one of a predefined set of sequences, each sequence in the set being either a single coefficient of amplitude greater than one, or a sequence of 1's and 0's starting with a coefficient of amplitude 1. The method includes forming a codeword for each formed event. Relatively short codewords are formed to represent events that are relatively more likely to occur, and relatively long codewords are formed to represent events that are relatively less likely to occur. In one implementation, each event is a run of none or more zero-valued coefficients followed by one of a predefined set of sequences, each sequence in the set being either a single coefficient of amplitude greater than one, or a sequence of 1's and 0's starting with a coefficient of amplitude 1.

Provided are techniques for allowing consumers to reserve a resource, in which potential consumers have a choice among a number of different reservation contracts for reserving a resource to be provided at a future time. Each reservation contract allows a corresponding contracting customer to elect whether to receive the resource and requires the contracting customer to make a first payment in aggregate if the resource ultimately is elected and to make a second payment in aggregate if the resource ultimately is not elected, with the first payment being higher than the second payment, and with both being nonzero.
