1) What is HDTV?

High-definition television (HDTV) is a high-resolution digital TV format. A high-definition TV signal has up to two times the color resolution and a picture that is up to six times sharper than that provided by a traditional regular TV set. HDTV also provides enhanced audio, such as Dolby Digital®. Back to top.

2) What equipment will I need to view HD programming? 

An HDTV set and a special set-top receiver are required. To work with our initial HDTV offering, your HDTV set must have a YPbPr component input and must support 1080i HD signals. Most new HDTV sets support the 1080i format. Please refer to your owner's manual or the manufacturer's website to determine if your HDTV supports 1080i. Back to top.

3) Do I need a new television to view an HD signal?

You must have an HDTV-capable TV to view any of our high-definition programming in high-definition format. Back to top.

4) Will Cox High Definition Cable support plasma TVs?

Most plasma TVs will have a YPbPr component input and be capable of supporting HDTV in 1080i format. Please consult your owner's manual or the manufacturer's website to verify HD capability of your plasma set. Back to top.

5) Is digital cable the same thing as HDTV? (High Definition Television)

Cox High Definition Cable refers to a type of digital cable that is at a higher-resolution than Cox Digital Cable. In order to receive Cox High Definition Cable, an "HDTV-capable" television set and a special set-top receiver will be required. Back to top.

6) How is a high-definition television set-top different from my current digital set-top?

The HD set-top box will be much the same as your current digital set-top box. The special HD set-top receiver has the component inputs and outputs that will allow us to pass HD signals to your HDTV set. Back to top.

7) What is the difference between "HD-ready" and "HD-capable" TVs?

Today's HDTV sets come in two forms: HD-ready and HD-capable. HD-ready sets have an HDTV receiver/decoder built-in, while HD-capable sets simply act as a monitor and require the addition of an external receiver/decoder to receive high-definition signals. Since most HD-ready sets only include receivers for off-air broadcasts (i.e., signals that are received using an antenna), you will still need a separate HDTV receiver to view HDTV programs with Cox High Definition Cable. Back to top.

8) Which channels will Cox High Definition Cable offer?

Initially, we will offer HBO HD, Showtime HD, NBC HDTV  (KNSD 7/39) and PBS HDTV. We are also in negotiations with other local broadcasters and cable networks to deliver additional programming as soon as possible. Back to top.

9) What is the difference between DTV, HDTV, and SDTV?

"DTV" is a general reference to digital television, as compared to "regular" television. HDTV is "high-definition" television, the highest resolution digital TV format. SDTV is "standard definition" television, like Cox Digital Cable. Back to top.

10) Why is Cox High Definition Cable better than satellite?

Cox High Definition Cable is easier to subscribe to and install, and includes local channels at no extra charge.  In addition to HBO HD, Cinemax HD, Starz HD and Showtime HD, which are available with your paid digital subscription to HBO, Cinemax, Starz and/or Showtime, Cox will deliver the local versions of NBC HD, CBS HD, Fox HD and ABC HD, and national PBS HD programming. Back to top.

11) I keep hearing about 720p and 1080i signal formats. What is Cox going to support?

The Cox set top will automatically convert all high-definition signals to 1080i format regardless of the format of the broadcast signal. Back to top.

12) Does Cox support the new 1080p format?

As of yet, there are no television stations that broadcast in 1080p. However, all 1080p TV’s will convert the 1080i signal to 1080p for you. Back to top.

13) 4:3, 16:9, Widescreen, Sidebars, Letterbox, Stretch, Pan and Scan --- what does it all mean?

4:3 (width: height) is the standard television shape. HDTVs have been manufactured in both 4:3 and 16:9 aspect ratios. 

16:9 (width: height) is the traditional shape of an HDTV, although some HDTVs have been designed with a 4:3 aspect ratio.

Wide screen is a term used for the 16:9 aspect ratio. Most HDTV sets are easy to identify because of their wide screens. These screens, which are usually a lot wider than they are tall, closely resemble their movie theater counterparts.

Sidebars present the entire picture in the middle of the screen and display black bands on each side of the picture. Sidebars are used when non-HD content is displayed on HDTVs with aspect ratios of 16:9.
Stretch is a tool that can be used on some HDTVs to stretch a 4:3 image to a 16:9 screen (vs. sidebars).

Letterbox presents the entire picture in the middle of the screen and displays black bands above and below the picture. Letterboxes are used to show HD content on a 4:3 aspect ratio TV. However, with a 16:9 aspect ratio HDTV, you will be able to view movies in their original wide screen theatrical format.

Pan and Scan are tools that can be used to present 16:9 content onto a 4:3 television (vs. letterboxes). Back to top.

14) Will I be able to view tapes with my VCR/DVD on my HDTV?

Yes, HDTVs will allow for VCR & DVD connections. Please consult your VCR/DVD owner's manual or manufacturer's website to determine if your equipment is capable of HD playback. Back to top.

15) How will high-definition programming look on my regular analog television?

Regular analog TV sets are not capable of displaying high definition programming. Back to top.
