ASKED QUESTIONS
WHAT’S THE RESOLUTION ON VIDÉOTRON’S HD CHANNELS?
CAN I CHOOSE THE RESOLUTION OF THE SIGNAL I RECEIVE?
Television stations decide which format a program will be broadcast in – although this doesn’t mean all of a
station’s programs will necessarily be broadcast in the same format.
It’s important to make the distinction between the image resolution you receive from a station, and the format
your television
displays it in. For example: if a station broadcasts a program at 480i and you have a 1080i TV,
it will convert the image to a
uniform 1080 on-screen lines by filling in the missing pixels. The program’s “real”
resolution, however, stays unchanged at 480i.
I’VE NOTICED SEVERAL CAPTIONING OPTIONS IN MY HD TERMINAL’S GENERAL SETTINGS,
SUCH AS FONT SIZE AND COLOUR. WHY ARE MY CAPTIONS ALWAYS IN BLACK AND WHITE?
Make sure the Captioning Options in your General Settings are set to Personalized. Custom font size and colour are
only available for programs broadcast using the new digital captioning standard, EIA-708B. Programs broadcast
using the old captioning standard, 608, do support captions, but only in black and white. A program’s captioning
standard is decided by the television station.
WHAT DOES AN HDTV’S “NATIVE FORMAT” REFER TO?
As you know, digital television programs can be broadcast in a variety of formats (480i, 480p, 720p, 1080i, etc.)
– but TVs are designed and built to display images in only one of these formats. This format is the TV’s native
format. This is why HDTVs must
be equipped to convert the formats of the programs they receive.
HDTVs are often classified according to their native formats. Today’s models are designed to display images
at either 720p or 1080i. If an LCD TV with a native format of 720p receives a signal from a television station
at 480i, it converts it to its native
format: 720p. To do this, it “fills in” the incoming image’s missing pixels,
bringing it up to its display capacity. The resulting image will always be in the same format: your TV’s native format.
