HDTV Sources
When examining possible sources, one must be careful to distinguish between true HDTV sources and normal (SDTV) video that is scaled or "up-converted" to a higher resolution. Examples of true HDTV sources are: 1.) Off-air ATSC receivers using HDTV
2.) Digital cable Set Top Boxes (STB) that offer HDTV service
3.) Digital satellite receivers that offer HDTV service (i.e. DirecTV, DISH Network, et al.) 4.) Windows Media High Definition Video 5.) HD-DVD and Blu-Ray DVD players Examples of EDTV sources are: 1.) DVD players featuring DVI / HDMI outputs (with built-in HDTV scalars) 2.) Video image processors (scalers) Another important consideration is analog versus digital sources. As previously stated, the ATSC has adopted a digital transmission system for HDTV; however, there are some HDTV sources on the market today that only offer analog outputs. Analog HDTV sources will become an increasingly greater rarity in a world of all-digital HDTV displays. This is especially true because all newer digital systems also employ HDCP (High-Bandwidth Digital Content Protection) to safeguard digital content against illegal pirating. HDCP cannot be implemented in analog systems. " Receiving HDTV signals over the air requires an antenna and a new HDTV receiver that can decode the digital signals. In general, an antenna that provides quality reception of over-the-air analog TV signals will work for HDTV reception. " Cable and direct broadcast satellite (DBS) subscribers will need a new HDTV receiver and other special equipment to receive HDTV programming.
