Thanks Bert - that's what I get too. And yet the video in Sylvie's article on fuses works just fine in IE8.

I am working at Altia Systems. We choose to keep audio separate for a good reason allowing the use of Wide band audio E.g. with Skype. To address the problematic setup issues Altia is using a cloud model which makes setting up supper easy.

David, I believe that the video works fine with IE9, but doesn't show up at all with IE8. Or at least, I saw it a couple of days ago using IE9, but now in this PC, with IE8, I just get a blank rectanlgle.

Don't know about "HD audio," Sylvie, but what they call "HD Radio" in the US is actually a particular version of digital audio broadcasting (they call the Euro version of this DAB and DAB+). The US version of DAB was contrived by a company called Ibiquity. It (optionally) retains the analog broadcast for FM or AM radio pretty much as is. If the analog spectrum is retained, HD Radio adds a digital channel by using the analog guard bands. If analog is not retained, then you get that much more digital capacity, because the slice of spectrum used by analog could instead be used for more digital space. The audio codec used is the same as what DAB+ uses in Europe (it's called AAC+, or HE-AACv2). So this codec, or other similar ones, would be used to get good audio quality from a relatively narrow digital channel. Matter of fact, since you brought up this subject, I discovered that the digital version of an FM station sounds very similar to a good analog rendition (although of course now you get more channels, in addition to the main one). But in the AM band, the quality difference is tremendous. Typical AM sound is limited much like telephone and videoconferencing, in practive to about 3000 Hz in each case. When you get the digital version of an AM station, it's strikingly better. Maybe not quite as good as HD Radio in FM frequencies, but pretty darned close. In my experience, you only see one digital program for each AM station, though, and three digital programs is common for each FM station.

My video conferencing experience had been similar until I decided to give up on having video and audio in one system. Now I just use a standard telephone conference and separately set up a video conference. Usually the video will be through Skype or Turbo meeting, but the audio will be dial-up phone. That doesn't help with the telephone bill, but it does give good performance. I just have yet to see an economical system that lives up to its claims in the real-world.

depends what kind of a meeting it is, I suppose. Sometimes it's more useful to see the faces of the people in the room. Think Sales meetings, etc.

Is that what they call "HD Audio" Bert? I agree with you that good audio makes a huge difference. It's currently the worst part of conference calls. Having some decent cinematic surround sound would really help who was talking and where they were in the room!

hmmmm.... I can see it, David.... Maybe you need to change browser? I'm running chrome and Firefox and can see it in both.
