Standards for efficient delivery of future services [Series Editorial]

The papers selected for this Series present various standards that assist in meeting the explosive demand for content delivery by efficient use of network resources. The first article, "Efficient HDTV and 3DTV Services over DVB-T2 using Multiple PLPs with Layered Media," by Hellge et al., describes how DVB-T2 can be adapted to the high transmission rates of future High Definition TV (HDTV) services including three dimensional digital TV (3DTV) services. The DVB-T2 standard from the Digital Video Broadcasting (DVB) consortium is designed to reuse the transmission infrastructure of the first generation digital TV but improves throughput and allocates the bandwidth and frequency resources in a flexible manner [1].
