| 20090119722 | LOCATING POINTS OF INTEREST USING REFERENCES TO MEDIA FRAMES WITHIN A PACKET FLOW - In one embodiment, a method comprises receiving a stream of transport packets encapsulating media packets, and generating a reference to the point-of-interest media packet relative to the location of the point-of-interest within the transport packet stream. The reference is generated for each media packet that is identified as a point-of-interest | 05-07-2009 |
| 20090190474 | BANDWIDTH-AWARE MULTICAST LOAD BALANCING ON A MULTI-INTERFACE HOST - In one embodiment, a network device having a plurality of network interfaces maintains a database tracking multicast memberships associated with the network interfaces. The network device then uses the database for load balancing received multicast traffic over the network interfaces. | 07-30-2009 |

| 20080310316 | Surrogate Stream for Monitoring Realtime Media - In one embodiment, a separate surrogate monitor stream provides real-time media monitoring statistics for non-media savvy protocols. The surrogate monitor stream contains packet transmission parameters, such as sequence numbers and time stamps, for associated media packets in the non-savvy media stream. The surrogate monitor stream also contains checksums derived from the media packets. The checksums are used to correlate the packets in the surrogate monitor stream with the media packets in the media stream. The information in the surrogate monitor stream is then used in conjunction with the non-savvy media stream to provide real-time media monitoring without having to modify existing infrastructure. For example, head-end video servers do not have to add Real-time Transport Protocol (RTP) support or deal with protocol upgrades like RTP/UDP co-existence. | 12-18-2008 |
| 20100036962 | Systems and Methods of Reducing Media Stream Delay - In one embodiment, a method includes requesting accelerated delivery of a specified media stream. The media stream contains a plurality of video frames. The method also includes receiving a response to the accelerated delivery request and selecting, based on the response, a source media stream. The method also includes receiving the source media stream into a buffer and decoding the received media stream from the buffer, at a selected playout rate. | 02-11-2010 |
| 20100036963 | Systems and Methods of Adaptive Playout of Delayed Media Streams - In one embodiment, a method includes requesting accelerated delivery of a specified media stream. The media stream contains a plurality of video frames. The method also includes receiving a response to the accelerated delivery request. The method also includes selecting, based on the response, a media stream source. The method also includes receiving a media stream from the selected media stream source into a buffer, and decoding the received media stream from the buffer, at a selected playout rate. | 02-11-2010 |
| 20100198979 | MEDIA STREAMING THROUGH A NETWORK ADDRESS TRANSLATION (NAT) DEVICE - A method and system for managing media streaming between clients on a client side of a network and stream servers on a stream server side of the network, wherein communications between the client side and the stream server side require a network address translation (NAT), involves allowing the same stream server side IP address to be shared amongst multiple stream servers so that the stream servers can simultaneously use the same IP address to source different media sessions. Because the stream servers can simultaneously use the same IP address to source different media sessions, a media session can be switched from one stream server to a different stream server without triggering STUN signaling or a change in the NAT mapping. | 08-05-2010 |

| 20100254462 | METHOD FOR REDUCING MEMORY USAGE WITH ACCELERATED CHANNEL CHANGES - Optimizations for rapid channel changes may be provided. In response to a channel change request, rate shaping may be used to provide a unicast packet stream at a first transmission rate for a first time interval before reducing the rate of the unicast packet stream to a lower transmission rate for a second time interval. During the second time interval, a multicast packet stream may be joined and the video frames associated with the unicast packet stream, which may lag behind the multicast packet stream, and the multicast packet stream may be synchronized. | 10-07-2010 |

| 20090006969 | Video microscopy system and multi-view virtual slide viewer capable of simultaneously acquiring and displaying various digital views of an area of interest located on a microscopic slide - A slide viewer capable of simultaneous display of more than one representation of an area of interest of a slide is provided. The slide viewer includes a database containing at least two data files representing different representations for a same area of interest on one or multiple correlated slides or at least two different digital presentations of the same representation. The representations are views of different illumination and/or of different contrast. Associated with the database are a processor and a display. The processor retrieves data files representing different representations of the same of area of interest and displays them on the display. A user is allowed to simultaneously view representations of the same area of interest, where the representations are of views different from each other by either illumination and/or contrast or by the digital information content presented, and/or by the information acquired from multiple correlated slides. | 01-01-2009 |
| 20090196526 | MICROSCOPY SYSTEM HAVING AUTOMATIC AND INTERACTIVE MODES FOR FORMING A MAGNIFIED MOSAIC IMAGE AND ASSOCIATED METHOD - A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions. | 08-06-2009 |
