DAB is only 128Kbps.. That kind of sucks, doesn't it? It will actually be a regression in quality from stereo FM broadcasts. Our eyes are generally fairly forgiving to a bad video quality (as we get used to it), however I think bad sound is much more irritating.
Digital consortiums have given us Satellite Digital Video Broadcasting over MPEG-2, DVD Video, the CD - these have all been excellent advances in terms of quality. Why didn't they choose a more decent bitrate like 192Kbps or around that? (Bandwidth issues perhaps, but hey, widen the bandwidth..)
- With proper encoders, properly configured, its not a regression over FM, its transperantly equal on normal sound sources. They can (and do) run stations higher - LyricFM is 160kbps; it has been 192. Most DAB receivers top out at 224, but the standard allows 320k. Bandwidth for DAB in Ireland is HIGHLY limited, so they can't launch more than two multiplexes on Band III until 2012 - to offer the current level of services they need the current level of compression.
- Also, TV by DVB-T or DVB-S is worse than a perfect analogue signal - most of us don't get perfect analogue though. Most of us don't get perfect FM radio, either; and DAB is in infinite improvement over AM. --85.134.154.44 21:09, 30 September 2007 (UTC)
