Q: What is HDTV?
A: High-definition television (HDTV) is a high-resolution digital TV format. An HDTV signal has twice the color resolution and imparts a picture that is six times sharper than that provided by a traditional analog TV set. The HDTV signal can also carry enhanced audio, such as Dolby Digital 5.1.
HDTVs must be capable of displaying at least 720 horizontal lines of resolution or higher. The pixels in HDTV screens are square, smaller, and spaced more closely together than standard-definition TVs.
HDTV screens are typically rectangular with an aspect ratio of 16:9 to support widescreen content, compared with the 4:3 aspect ratio utilized by traditional analog TV sets. However, there are some HDTVs that only have a 4:3 screen. Not all widescreen broadcasts are high-definition; DVD’s, for example, can display widescreen formats even though the content is 480i or 480p, which is not high-definition.
In order to take advantage of your HD television set, you must have a Morris Broadband HD set top (converter) box.
A: Make sure you have tuned to an HD channel available in your area. Not all channels are broadcast in HD. Check our channel lineup for additional information.
Ensure connections are correct.
A: Not every show currently broadcast by an HD station is in HD format. You can assume that if you are getting a picture on the HD channel, then your equipment is functioning properly. You may want to check your HD settings to “stretch” or “zoom” the picture to fill the screen area.
A: Check that your component video cables are connected correctly. Make sure the 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.
Make sure the connections are secure; that the RCA plugs are pushed completely into the ports
Adjust the convergence and luminance settings on your television set.
Adjust the color, contrast, brightness, and tint on your television set.
A: Roughly half of prime time TV programs of the major networks is available in the (16:9) HD format. The other half is broadcast in the standard 4:3 format.
The aspect ratio of the content is controlled by the content providers, such as Discovery Channel, HBO, etc.
Whether the HD signal is in the 4:3 or 16:9 format, the HD picture quality will still be better than an analog or standard digital signal. The reason is that up to five times more information, or data, can be displayed with the HD broadcast than with the standard digital broadcast, regardless of the aspect ratio.
A: When a standard-definition (4:3 aspect ratio) program is viewed on a widescreen (16:9 aspect ratio) HDTV, the HDTV centers the image on the screen with black or gray bars on either side (known as sidebars).
Widescreen (16:9 aspect ratio) content on a 4:3 aspect ratio HDTV will typically have black bars on the top and bottom of the screen. This is called letterboxing.
A: The picture quality of the HD programming you receive is primarily determined by the content provider. If you are receiving video on an HD channel, you should assume that your HD service is functioning properly.
A: The 4:3 aspect ratio is the shape of the standard television monitor and is best described as “squarish”. The 16:9 aspect ratio is the shape of most HDTV monitors and is best described as rectangular. HDTVs have been manufactured in both 4:3 and 16:9 aspect ratios.
Widescreen is a term used for the 16:9 aspect ratio. Most HDTV sets are easy to identify because of their widescreens.
Pan-and-scan is a Hollywood technique for creating 4:3 content from a 16:9 master by selectively cropping the rectangular image (16:9) into the squared (4:3) format.
