IP datacasting and channel error handling with DVB-H

DVB-H is a terrestrial digital TV standard which consumes less power and allow user to move freely when receiving signals. Its deployment also signifies the convergence between broadcast network and data networks as both video signals and other data programs are transmitted in a shared media. In this paper we discuss the channel error problems under different scenarios of this convergence. Partial solutions, such as enhanced forward error correction were provided by the standard but other aspects still need further exploration. We present some early results and discuss possible directions in the future.
