  • Patent number: 9031563
    Abstract: Methods, systems, and devices are described for improving inter-network mobility performance in multiple network wireless communication systems by using channel avoidance information from a first network using a first radio access technology (RAT) to modify inter-RAT behavior of a second network using a second RAT. In some embodiments, the second network queries the first network for channel avoidance information and applies the channel avoidance information in suppressing inter-RAT channel measurements, avoiding inter-RAT redirection, and/or avoiding inter-RAT reselection. In embodiments, inter-RAT channel measurement suppression, inter-RAT redirection avoidance, and/or inter-RAT reselection avoidance is performed by the mobile device. In other embodiments, channel avoidance information of the first network may be communicated to other network entities of the second network and one or more of these entities may modify various inter-RAT behaviors.

  • Patent number: 6212680
    Abstract: Multi-channel Electronic Program Guide acquisition and soft picture-in-picture system for use with digital television receiver. The digital television receiver uses its central processing unit (CPU) to perform a software decode of packets received from a main tuner and/or a picture-in-picture. This allows the CPU to display video from pictures within the same RF channel or within another channel simultaneously with video information decoded in real-time by a hardware decoder. Also, in the case of a digital television with two tuners, the CPU can acquire and accumulate EPG data from multiple channels.
