In its recently released study covering the entire commercial satellite transponder leasing sector, NSR projects that worldwide carriage of new standard definition (SD) and high definition (HD) channels for all categories of television services will account for between 75% and 85% of C- and Ku-band transponder demand growth in most regions around the world. NSR projects in its Global Assessment of Satellite Demand, 4th Edition (GASD) report that approximately 1,750 additional SD channels and another 150 HD channels will be placed on commercial C- and Ku-band satellite payloads every year for the six-year period between 2006 and 2012. In fact, DTH services alone will contribute nearly 4,000 SD channels and just fewer than 500 HD channels by 2012 according to NSR’s latest industry forecasts.
