- (Has there been any HDTV broadcasts from Barcelona to Japan or US ?)
-
- I have a very short paper about the Barcelona HDTV setup (in Finland) and
- if I understand it correctly, the transmission from Barcelona is
- European HDTV, HD-MAC. These transmissions are done by European
- Vision 1250 production project and the transmissions are sent as
- European-wide satellite transmission.
-
- Accordingly to this paper there is 1250 lines, 50 frames/sec and the
- broadcasting technology is HD-MAC in the European HDTV while in the
- Japan they have 1125 lines, 60 frames/sec and MUSE broadcasting.
