US08311129B2 Temporal video filtering
In various embodiments, temporal filtering may be used to reduce noise over time in a series of video frames.

For example, if substantial motion is not detected, the temporal filter for the block of pixels may be stronger (i.e., reduce more noise) than the temporal filter applied to a block of pixels for which substantial motion has been detected.

US08311014B2 Virtual care-of address for mobile IP (internet protocol)
An IP (Internet Protocol) session for a mobile node is carried out through the use of a virtual care-of address. A foreign agent sends an agent advertisement to the mobile node to allow the mobile node to choose from a list of IP addresses of the foreign agent.

Rather, the virtual care-of address shifts the tunneling decision from the mobile node to the foreign agent. Supporting multiple tunnels between home agent and foreign agent allows resilience, redundancy, and service-level differentiation to mobile node traffic without involving the mobile node in the process.
