Abstract

Digital Video Broadcasting - Handheld (DVB-H) specification suite enables reception of point-to-multipoint multimedia transmission with mobile devices. It provides good forward error correction (FEC) capabilities to combat transmission errors. However, transmission errors can be occasionally so severe that FEC decoding fails. The residual transmission errors can degrade the audio-visual quality dramatically. This paper presents an error control method, called synchronized audio redundancy coding. It aims to ensure audio continuity under severe channel error conditions. The presented method was compared to conventional FEC-based error protection of DVB-H in a large-scale subjective experiment. It was found that synchronized audio redundancy coding outperformed the conventional error protection in most test cases.

Keywords: DVB-H Audio Redundancy Error Resiliency.
