Frequently Asked Questions About HDTV
What is Digital Television?
Digital television (DTV) is a huge leap forward in television technology compared to analog television that has been widely available since the 1940s. DTV is delivered and displayed using digital encoding, similar to the way a PC operates. By using digital technology, there is no variation in picture and sound quality from the origination point until it is displayed on your television. You always receive a high-quality picture without the wavy lines or static you might sometimes get from a weak analog signal. Because DTV receives and displays digital images that contain many times more picture elements (pixels - the small dots that make up the color image on your screen) than standard analog television, you can get a sharper on-screen image than with analog. Additionally, DTV supports CD-quality sound. DTV includes SDTV (Standard Definition Television), EDTV (Enhanced Definition Television), and HDTV (High-Definition Television). That means that all HDTV is digital, but not all digital TV is high-definition. A high-definition program must originate in HD format and be broadcast in HD format. Having an HDTV system does not mean that everything you watch will be in high-definition. Getting the signal from digital cable also does not mean it is high-definition.
What is Standard-Definition Television?
Standard-definition television (SDTV) is basic digital television programming delivered by cable. Typically, the SDTV screen is the same, nearly square shape as an analog television screen. Digital images on an SDTV set are crisp and clearnoticeably better than on a standard analog television set using an antenna to receive over-the-air signals.
What is High-Definition Television?
High-definition television (HDTV) is a completely new way to send and receive television broadcast signals. HDTV images are made up of pixels that are much smaller and closer together than those used in standard analog television, and there are millions of them. Thus, HDTV can display five to six times the detail of analog television to deliver picture quality that is much more realistic, dimensional, and precise. SDTV programs can be viewed on an HDTV. Another feature of HDTV is digital surround sound using Dolby Digital, which is the same technology used to produce the sound you hear in movie theaters.
Are Local TV Stations Broadcasting in HDTV?
Many local TV stations are transmitting digital signals. However, transmitting a digital signal does not mean transmitting an HDTV signal. Some stations are using the new bandwidth to broadcast several standard-definition channels. Most stations, once they begin broadcasting in digital, are offering HD content from their parent network (for example, CBS, ABC, NBC, Fox, WB, UPN, and PBS).
Why Are Some HDTVs 4:3 Aspect Ratio and Others 16:9?
The aspect ratios differ because television manufacturers build both standard-screen and widescreen HDTVs to appeal to consumer viewing preferences. The two aspect ratios are as follows: On wide-screen (16:9) HDTVs, the programming is displayed on the full screen. On standard-screen (4:3) HDTVs, the programming is displayed in letterbox format in the middle of the screen. (There are bars surrounding the picture.)
Where Are the Connection Diagrams?
The diagrams at the end of this guide show examples of common ways to connect the 8240HD to your HDTV, DVD, and home theater receiver. However, these diagrams do not show every possible combination of devices. Refer to the users guides that came with your other electronic devices for further information.
What Cables Do I Need?
Some of the cables and adaptors shown in the diagrams may not be included with the 8240HD. The required cables are shown in the connection diagrams in this guide.
What is the Difference Between a Standard-Screen and a Wide-Screen HDTV
The type of screen your HDTV has (wide screen or standard screen) determines how the 8240HD displays programs on the screen. The picture format for an HDTV is a combination of aspect ratio and screen resolution and is different for standard-screen and wide-screen HDTVs.
What is Aspect Ratio?
An aspect ratio is the ratio of the width to the height of the TV screen. The aspect ratios differ because the television industry manufactures both standard-screen and wide-screen HDTVs to appeal to consumer viewing preferences.
What is the Screen Resolution and Scan Rate?
The screen resolution indicates the amount of detail that the picture displays. Resolution is identified by the number of display lines on the screen. The techniques that an HDTV uses to paint the picture on the screen are referred to as progressive and interlaced. With the progressive method, every pixel on the screen is refreshed simultaneously. The interlace method involves refreshing pixels in alternation first the odd lines and then the even lines. For advance setup, select the scan modes that your TV can support. Refer to your DVR and HDTV users guides to choose the proper scan rates (480i, 480p, 720p, 1080i) for your setup. For example, a resolution of 1080i indicates that the screen shows 1080 lines in an interlaced display, and 480p indicates that the screens shows 480 lines in a progressive display. Notes: The screen resolution (1080i, 480p, and so forth) is sometimes referred to as the scan rate. The terms are interchangeable. You can stretch and zoom the displayed picture using the built-in capability of the 8240HD by pressing the # key on the remote control. Refer to your DVR users guide for more information on this feature.
A standard-screen HDTV has a 4x3 aspect ratio. The screen is 4 units wide for every 3 units tall.
A wide-screen HDTV is one-third wider than a standard-screen HDTV. The screen is 16 units wide for every 9 units tall.
A screen resolution of 480p or 480i fills the screen.
A screen resolution of 720p or 1080i fills the screen.
Connecting the 8240HD to an HDTV With an HDMI Connector
WARNING: Electric shock hazard! Unplug all electronic devices before connecting or disconnecting any device cables to the 8240HD.
Important Note Regarding the HDMI Interface on the 8240HD
The HDMI interface will automatically configure the audio output for a format supported by the television. Because not all TVs support a Dolby Digital input, the HDMI interface may automatically select a 2-channel stereo audio configuration instead of Dolby Digital. When the output is configured for 2-channel audio, this configuration is carried over to the other digital audio outputs of the 8240HD. This configuration prevents your home theater system or Dolby Digital decoder from providing the full Dolby Digital surround sound effect. On the 8240HD, you may override the automatic selection of audio by the HDMI interface by completing the following steps. 1. Press SETTINGS twice on the remote control to open the General Settings menu. 2. Press MOVE UP or MOVE DOWN to select the option Audio: Digital Out. 3. Press MOVE RIGHT to select Dolby Digital. This setting will send Dolby Digital audio to the HDMI, DIGITAL AUDIO OUT, and OPTICAL AUDIO OUT connectors on the 8240HD. Note: If the TV (video/audio monitor) connected to the 8240HD using HDMI is not Dolby Digital capable, it may not produce audio through its speakers when the Audio: Digital Out setting on the 8240HD is set to Dolby Digital. You can either switch the Audio: Digital Out setting back to HDMI when you are not using the home theater or Dolby Digital decoder, or you can connect the baseband audio outputs (OUT 1 Audio Left and Right) to the TV.
Connecting the 8240HD to an HDTV With a DVI Connector
Note: When connecting the HDMI connector to the DVI connector on your HDTV, you need an HDMI-to-DVI adaptor, and you need a separate audio connection.
