Abstract: A method for processing a plurality of motion vectors for a video frame to be interpolated using a first reference frame and a second reference frame, each reference frame having a content map, the method including partitioning the video frame to be interpolated into a plurality of areas; determining a number of motion vectors passing through one area of the plurality of areas based on the content maps of the first reference frame and the second reference frame; and generating a motion vector to assign to the one area based on the number of motion vectors passing through the one area. An apparatus for performing the method is also described.

Abstract: The invention described herein enables a form of downlink macro-diversity in packet-switched cellular networks. It allows packets to be selectively delivered from a network/internetwork to an end node, e.g., a wireless communication device or terminal, over a set of available link-layer connections to/from the end node, through one or more access nodes, e.g., base stations. Downlink macro-diversity is particularly important when the link-layer connections between the end node and the corresponding access node, e.g., the access links, are subject to independent or partially correlated time variations in signal strength and interference. In accordance with the invention, the end node dynamically selects the downlink to be used out of a set of available access links on a per packet basis subject to prevailing channel conditions, availability of air-link resources and other constraints.
