BBC R&D

Abstract

This paper presents brief technical aspects of a spectrally efficient multiple-input multiple-output (MIMO) prototype radio-camera system developed by BBC R&D. Radio-cameras are usually used to broadcast live coverage of events and this prototype system uses half of the required channel (usually 10MHz frequency bandwidth) compared to conventional radio-cameras and hence the name of the system as halfRF. This has attracted a lot of interest within the outside broadcast (OB) community where frequency spectrum allocated for programme making and special events (PMSE) are limited and under pressure from other users of the spectrum. The halfRF system is mainly based on the DVB-T standard but it also incorporates advanced features adopted in DVB-T2 and DVB-NGH. This paper then describes a programme trial during a high-profile sports event, the Six Nations Rugby Union match between England and Italy at Twickenham stadium (London) in March 2013. The article concludes with the latest development of the system and future research by the team.
