regulates South Korea's airwaves, selected three broad- casting companies and three consortia comprising dozens of companies each to provide terrestrial-based multimedia services. A big plus for T-DMB is that terres- trial broadcasts will be free because the government forbids charging for what are considered public broadcasts. Although DMB is proprietary and designed for the Korean market, because DMB can send content to numerous consumers on the same frequency band, the technology scales gracefully and profitably. In fact, as the number of users increases, operational costs decrease. As a result, Korea is inter- ested in having DMB adopted globally as a standard. Both LG (www.lg.co.kr/ english) and Samsung (www.samsung.com) have major investments in DMB and hope that it will be adopted throughput Europe as a standard. South Korea's minis- try of communications has created a special task force to lobby for European use of the DMB standard, and Korean companies have performed several demonstrations. DVB-H The ETSI chose DVB-H as a standard in November 2004. ETSI recommendations for a standard are voluntary, not compulsory, but DVB-H has already generated signifi- cant industry activity, including technical and commercial trials and a range of prod- uct launches. Based on DVB-T, DVB-H is fully backward compatible. It offers additional features to support handheld portable and mobile reception. The specifica- tion calls for 15Mbps in an 8MHz channel. Key advantages of DVB-H include the fact that it saves batteries and offers mobility with high data rates, single-antenna recep- tion, impulse noise tolerance, increased general robustness, and seamless handoffs. DVB-H is meant for IP-based services. It can share DVB-T "multiplex" (i.e., the bandwidth of a DTV channel subdivided into multiple subchannels) with MPEG-2 Chapter 16 Emerging Wireless Applications services. For a TV-like experience on a handheld device with a smaller screen, the next-generation MPEG standard (MPEG-4-AVC) will be needed. Although DVB-H will d
