MPEG4 is a more efficient format of broadcasting which has the ability to provide better picture quality, particularly for sporting events. The Federal Government is strongly encouraging national broadcasters to use MPEG4 technology into the future as it requires less of the national spectrum to transmit pictures. Since 2009, the vast majority of TVs have been made with MPEG4 compatibility as a result. Approximately 80% of Australian homes now have MPEG4 compatible televisions. Non-compatible TVs can view a free-to-air MPEG4 broadcast with the use of a set top box or Personal Video Recorder (PVR).
