What is HDTV?

A High Definition Television (HDTV) is a type of Digital Television (DTV) that receives and/or displays high definition television images and surround sound. HDTV programming and TVs together provide a detailed, sharper image due to the increased number of pixels contained in the received digital. HDTV screens are wider than the traditional analog TV screens. Analog TVs offer a screen aspect ratio of 4:3 while HDTV’s offer an aspect ratio of 16:9, which is similar to a movie screen. This allows you to see movies as they were filmed without reformatting. There are also HDTV capable sets that have the regular TV 4:3 ratio, but format HD content in a letterbox presentation (with black bars on the top and bottom of the TV image).

Enhanced Definition Televisions (EDTV) also exists. These 4:3 aspect ratio TVs can not receive HD formatted signals. They can receive enhanced definition signals, which do not have the detail of an HD signal, but do improve on the standard definition (SD) picture.

Note: Channel availability varies by location. Country Cablevision is looking to add many more High Def channels by year end.

What do I need to get Country Cablevision HDTV?

You will need an HD capable digital receiver from Country Cablevision and an HDTV set. You will also need Component video cables and Composite audio cables or an HDMI cable to connect this equipment together. You should have these available when you have Country Cablevision HDTV installed.

Is Country Cablevision Digital the same as Digital TV?

Actually, digital cable and digital TV are different. Both use a digital signal, allowing for more data (e.g., channels, music, movies, etc.) to be sent across our network to your home versus an analog signal. The digital receiver receives formats and outputs the signal so that you can view it on your television.

However, you can receive Country Cablevision Digital on any TV, not just digital televisions. HDTV requires new production (the making of the programs we watch), new transmission (broadcast stations), and specific equipment (HDTV set and decoder) for reception.

Note: If any of the components above are not HD-compatible, you will see a digital-quality image, not an HD-image.

If I get a Country Cablevision HDTV-capable receiver/decoder, can I watch HD programming on my regular TV?

You need to have a High Definition television with a HD receiver to display HD content in HD. Some HD receivers can be configured to down convert the received HD signal into a standard definition signal for display on SDTVs. The viewed content would no longer be HD content, but would be viewable in SD.

I already have an HD television. Do I still need a Country Cablevision HD-capable receiver/decoder?

Yes, you will need the Country Cablevision HDTV receiver that includes a decoder to receive the HD programming.

Why do I need an HDMI cable?

If your TV has an HDMI input then the HDMI cable is the absolute best connection available for the HD or HD/DVR box to your tv. It is necessary in order to view the HD channels in full HD format on your tv. Component cables can also be used but it is not near as easy as the HDMI hookup. HDMI cables pass the video and the audio signals all in one cable instead of several different cables. We supply HDMI cables with our HD and HD/DVR boxes if your tv has an HDMI input. A regular non-HD tv can watch the HD channels (not in true HD) without an HDMI cable as long as your have an HD or HD/DVR box.

How can I tell if I am watching an HD channel on my HD or HD/DVR box?

The best way to tell if you are watching an HD channel in general is by learning which channels the HD are. Keep in mind sometimes the local channel HD’s don’t always show true HD format shows. Sometimes during the day they show regular format shows that have black bars on the sides, this is normal. When they air a show that is filmed in HD format it normally has no black bars on the sides. The other method of telling if you are watching an HD channel is to watch the format indicator (light) on the front of the box. The format indicator is to the right of channel or time on the front display. If it is at the bottom which is 480i then you are not on an HD channel. If you see it at the top or the next one down, 1080i and 720p respectively, then your are on an HD channel. There may be exceptions to this rule at times but normally it is correct.

Why do I see black bars on the sides of some channels using my box?

If you are seeing black bars on the sides of the picture on your “widescreen” tv while using a HD or HD/DVR box then the film or show you are watching was either not filmed in an HD format or has not been upconverted to an HD format by the network. In that case you are actually watching the film or show in the format it was supposed to be watched. You can usually spread it out by using the TV remote and changing the “pic size”, “format”, “ratio”, or “aspect” buttons but keep in mind it may make the picture or actors look short and wide. The best way to do it is leave your TV on auto aspect or normal to watch it the way it was meant to be watched. When you tune to a HD channel your picture, if the TV is set to auto aspect or normal, will naturally fill the entire screen according to what the content was filmed in. Keep in mind that some of the local networks HD channels will not fill the entire screen during the day on normal shows. If the show is filmed in HD format and you are on an HD channel it should fill the entire screen.

Why does it sometimes take several seconds for the picture to appear when changing some channels?

Sometimes on your HD or HD/DVR box when you are changing channels from an HD to a regular no-HD and back you will see the screen flash a time or two and it may take several seconds for the picture to appear. This is normal since the box is having to change formats and tell the tv to also change formats.

Why does it sometimes take a long time for the picture to come on when I turn my box on?

If your HD or HD/DVR box is having to read the format and change its format then it may take several seconds before the picture comes on. Also if the box is hooked to the TV using an HDMI cable it may take a bit for the box to talk to the TV and handshake with it. This is normal.

Why does changing the volume on the box (seeing the progress bar) not actually change the heard audio?

While using an HDMI cable to hook your HD or HD/DVR box to your tv the volume on the box will not actually change the heard volume on the TV. This is a problem easily fixed by you with the remote. First on the remote you need to press menu, then select the Home icon and hit OK. Next scroll down to setup (may have to scroll all the way down off the page to find it) and click OK. Highlight Audio Setup and press OK. Next highlight “Optimal Stereo” and hit the right arrow button to turn it on and then press the Exit button. Next hold down the TV button on your remote for 6 seconds or until the light goes solid (lights on the top of remote will start flashing and then the TV light will go solid). Once it goes solid press the Volume + button on the remote and the TV light will flash 3 times. From now on when you press the volume button on your remote it will turn the TV’s volume up and down instead of the boxes and the volume will work correctly.
