I couldn't believe what I was reading in in Monday's Guide/Icon (SMH Monday,
09.07.07)
Article by Bill Bennett and Simon Tsang:
On page 8 of The Guide (article: Sharp End Of The Stick) we have this
information:
"....The whole cycle repeats 60 times a second. With interlaced scanning,
every second line is refreshed 60 times so the whole picture is refreshed
only 30 times per second..." Gee, you could have fooled me guys. I guess
channels convert US/ATSC 1080i/60 to DVB 1080i/50 at massive expense just
because they can?
Bzzt!!!!!! It's 50Hz in this country and in the UK and most other DVB
countries which by my calculations is 50f/50f for progressive and 50f/25f
for interlace.
and then we have this:
"Australian broadcasters are commonly sending out digital signals at 480i,
480p and 576p resolutions."
What?! I thought (and it has never been 480 anything apart from limited non
public ATSC trials before we chose COFDM DVB-T) it was either 576i (SD),
576p (ED) and 720p, 1080i (HD). Correct me if I'm wrong please. All at 50Hz.
Then the editor really drops it on page 9 in the side bar "What Do I Need To
Get HDTV?" "To live in the right place - this includes all metropolitan
areas. To check, see www.db.org.au."
Erm....we're missing an "a" after "db" there aren't we?
And all of this in article explaing HD Digital TV to non-technical people.
The mis-informed leading the blind, I say.
Tsk, tsk.
