Abstract: Techniques for managing receiving, at a network receiver device, from a video streaming solution, segments for each of a plurality of video streams over one or more multicast channels, where the network receiver device is configured to cache the segments for consumption by one or more client devices. A first network congestion condition is satisfied at the network receiver device. In response to detecting the first network congestion condition is satisfied, a first one of the plurality of video streams having a lower priority is selected, relative to a second one of the plurality of video streams. Segments for the first video stream are requested using an alternate channel. Embodiments unsubscribe from a first one of the multicast channels for the selected first video stream.

Abstract: In one embodiment, a method includes receiving fast channel change (FCC) data for a program, the FCC data having a first set of content identifiers, receiving a video stream for the program, the video stream having a second set of content identifiers, changing at least one of the first set of content identifiers of the FCC data or the second set of content identifiers of the video stream to a common set of content identifiers, and providing the changed FCC data and video stream to a decoder.

Abstract: The image pipeline for a vision system includes a series of digital image processing boards controlled by a computer. A video camera generates from a laser beam reflected from the target surface an RS-170 analog video signal which is converted to a digital signal for processing. Bins of digitizing parameters suitable for several target surface reflectivities are stored in computer memory. The appropriate bin is selected from histogram data of pixel intensity levels generated by one of the image processing boards using digitizing parameters from a reference bin. Improved imaging, especially of black surfaces, is achieved by scanning a laser beam to generate a light stripe over a number of image frames using the digitizing parameters from the selected bin and integrating the data from the successive frames using the image processing boards.
