2-1. Sending Signals 9 2. IMPORTANT OVERVIEW Digital broadcasting is a new way of sending programs over the airwaves with superior qual- ity video and audio. The DIRECTV ® HD Receiver enables you to take full advantage of digital broadcasting. To fully enjoy it, it is helpful to understand the ways that program signals are sent. There are two types of TV signal formats; analog (often called NTSC format; National Television System Committee) and digital (ATSC format; Advanced Television System Committee). Digital formats are classified into three categories: High Definition (HD), Enhanced Definition (ED), and Standard Definition (SD) according to the resolution or digital picture quality. There are also three ways that program signals can be received; over-the-air (NTSC, ATSC), cable (analog and digital), and satellite. This receiver contains a QAM tuner which should allow you to receive unscrambled QAM dig- ital television programming via subscription service to a cable service provider. This receiver will not be able to tune encrypted (scrambled) digital programming or advanced interactive digital cable services. Contact your local cable service provider for further information regard- ing the availability of unscrambled digital cable programming.

TV Signal Formats The digital TV standards allow several different formats. Broadcasters can choose between four formats: • 480p - The picture is 704 x 480 pixels, sent at 60 complete frames per second (480i is also possible, sent at 60 interlaced frames per second). • 720p - The picture is 1280 x 720 pixels, sent at 60 complete frames per second. • 1080i - The picture is 1920 x 1080 pixels, sent at 60 interlaced frames per second (30 complete frames per second). (The “p” and “i” designations stand for “progressive” and “interlaced.” In a progressive for- mat, the full picture updates every sixtieth of a second. In an interlaced format, half of the pic- ture updates every sixtieth of a second.) The 480i format is called SD. 480p format is called the ED format. 480i is roughly equivalent to a normal analog TV picture. The 720p and 1080i formats are called the HD formats. Some analog televisions can display a picture 720 pixels wide by 480 pixels high, that’s a total of 345,600 pixels. HD digital signals can have a maximum resolution of 1920 x 1080, that’s 2,073,600 pixels, or six times more pixels than the older resolution. Pictures will be crisper and cleaner, with more detail in every close-up and every panorama.

Pressing the DISPLAY FORMATbutton repeatedly on the front panel changes the display formats following order: 1080i→720p→ 480p→480i→native→variable 1 →variable 2 →variable 3 →EZ DVI. In1080i, 720p, 480p,and480imodes, all input signal formats are converted to the chosen dis- play format. In native, variable 1, variable 2,andvariable 3modes, the output display for- mat is automatically adapted depending on input signal format, as follows. In EZ DVI mode, the output display format is automatically adapted based on the preferred res- olution format of the DVI-HDTV monitor. The format may be converted from the original broad- cast format. Note : Only one of the YPbPr, RGB or DVI-HDTV jacks is available at any one time, depending on the TYPE switch setting and DVI-HDTV connection status. Note : The EZ DVI mode is only available when a DVI-HDTV compatible monitor is connected to the receiver. 12 2-4.
