Abstract

In this paper we discuss possible benefits of transmitting SI frames as an error resilience tool in UMTS video streaming. SP and SI frames can be used to stop temporal error propagation, as an alternative to the regular insertion of I frames. Since their application relays on feedback information from the mobile equipment, different delay scenarios have been investigated. The performed transmission simulations show enhancement of the rate-distortion behaviour when using SP and SI frames with reduced feedback times. The error traces were measured at transport block level in a live UMTS mobile network.
