High-definition television is a type of digital television that combines extremely high resolution with Dolby Digital Surround Sound and provides a crisp, detailed image. A high-definition TV signal has five times the resolution than what can be displayed by a traditional analog TV set. All HDTV screens are wider than they are tall, providing a wide screen view that allows you to see programming as it was filmed, without reformatting.
Digital cable is a type of television signal. HDTV is the highest quality in digital signals, offering better resolution and sound than a standard digital signal. Digital cable can be watched on your existing standard television if you have an Astound digital cable box. HDTV requires a high-definition television, an Astound digital receiver or DVR, and a digital cable package with Astound.
In order to receive Astound high-definition service, a high-definition television and an Astound HD receiver or HD-DVR with HDMI or component cable connection are required.
Yes. In order to receive any HD channels included with your subscription, beyond the local broadcast channels, you must have a high-definition television and an Astound HD receiver or DVR.
HD Signals will not display on standard definition TV sets, because those TVs don't include the advanced technology required to display HD.
"Aspect Ratio" refers to the ratio between the horizontal (width) measurement and the vertical (height) measurement of the screen. The two aspect ratios used are 4:3 and 16:9. That is, (4) units wide by (3) units high, and (16) units wide by (9) units high respectively. The 16:9 aspect ratio is the standard for HDTVs because significantly more information can be displayed on the screen.
Not all programs are broadcast in high-definition and therefore programs will not always be full screen. Not every show currently broadcast by an HD network is in HD format. If you are getting a picture on the HD channel, you can assume that your equipment is functioning properly. You may want to check the settings on your HDTV set (consult your HDTV user manual).
If using a component video cable, ensure that the cables are connected correctly (i.e. Y is connected to Y, Pb is connected to Pb, and Pr is connected to Pr). Crossing these cables will mix up the picture colors. If using an HDMI connection, check your TV settings.
