Paper Abstract

A new low-cost video frame-rate up conversion (FRC) technique that exploits compressed-domain information is proposed in this paper. Recent worldwide growth of digital video applications such as home AV network or mobile multimedia have been demanding higher video compression ratio in order to meet system requirements related to limited bandwidth or storage capacity. Enhancement of temporal resolution using FRC at decoder side is attractive in a sense that the R-D performance can be maintained even at low bitrate condition by dropping frames during encoding and recovering them at decoder side by FRC. The proposed FRC method aims to provide accurate estimates of block-based motion vectors for recovered frames based on compressed-domain information. The goal of our study is to realize a decoder design with robust FRC over a variety of implementation platforms from mobile to consumer set-top.
