[HCDX] D DAY IN THESSALONIKI

["Zacharias Liangas " <greekdx@xxxxxxxxx>]

D Day  for Thessaloniki

Yesterday 15-12010 is the D-day (digital day switchover )though in pilot 
stage  for nationwide TV channels relaying in Thessaloniki. Most of the 
western part of the city including parts of the north areas including us in  
Filiro and Retziki are now able to watch the 7 TV channels via 2 transmitters 
using MPEG 4 compression technology and COFDM mode.

The 7 TV channels are Ant1 Mega SKAI STAR MACEDONIA Alter and 
Alpha which last year started a consortium  called Digea TV to promote the 
digital switchover  in Greece for the commercial TV channels (separate from 
the national TV network). Thessaloniki is the second point with Athens to 
follow in several months but in the first semester of 2010. First press release 
was on 16-12-09 and all members of the consortium started banners from 
the 1rst of this year to inform for the digital switchover that just made from 
the point of Filipion central part s of the city but on the mountain) but leaving 
the older main point of Hortiatis (E of the city) still  using analogue  mode

More for this including two coverage maps in this page

As for now 15-1-2010 and 0700 LT the switchover has been completed  
using two 'transponders' on 25 and 29  for the digital format, previously used 
by Macedonia TV  , another (?? No info ) as  spare while all other  freqs use 
a notification 

Tested my father in law's TV monitor  with built in decoder yesterday 15.1 
morning 0700 LT . channel 25 was with 3+1 TV channels in the clear 
(Anntenna , Alpha Alter and spare ), while ch 29  due to some in band-QRM 
showed halted or low-framed video (channels available MAk TV , Mega Sky 
Star) , though today signal was 100% . This is possibly caused due to a  2 
antenna mixed system used so far to pick signals from the two main 
transmission systems.

As for the picture , with the TV set  is better  than using a sat system
