Video Encoding and Splicing for Tune-in Time Reduction in IP Datacasting (IPDC) Over DVB-H
A novel video encoding and splicing method is proposed which minimizes the tune-in time of “channel zapping”, i.e. changing from one audiovisual service to another, in IPDC ov...

Worst-Case to Average-Case Reductions Based on Gaussian Measures
We show that finding small solutions to random modular linear equations is at least as hard as approximating several lattice problems in the worst case within a factor almost line...
