If the CRTC has any sense….

They’ll run away screaming “NOOOOOOOO!” to this notion:

Canada’s plan “B” might include iBiquity.

(as reported by Inside Radio)

Let’s just hope that this is more of iBiquity’s wishful thinking, which is often presented as actual important news being based in fact.  By iBiquity.

Why does the CRTC need a plan B anyway?  Is in not enough that Eureka 147 failed mainly due to lack of public interest?  If it was something that was commercially viable, wouldn’t it have taken off on its own?  Now they are thinking of ruining the FM broadcast band, which, in my experience in Canada, is working perfectly fine.

Who says “digital” is better?  If anything, what has been discovered in this country is when it comes to HD radio, digital is worse.  Thus far, HD radio has the following going for it:

  • Proprietary system with expensive licensing fees
  • Complicated infrastructure
  • Insufficient building penetration
  • Poor performance in mobile reception evironments
  • Lack of original programming
  • Adjacent channel interference
  • Poor receiver sales
  • Lack of general interest and/or knowledge by public

All of these things have been well documented.  If you work for the Canadian Radio Television and Telecommunication Commission (CRTC) and are thinking about this, contact me.  I’ll even invite you down for a drive around and you can experience HD radio, in all its glory, first hand.

Chief Executive Officer of Northeast Public Radio gets it wrong.

I was listening to locally produced program “The Media Project” on Northeast Public Radio this afternoon when Alan S. Chartock began speaking about HD radio®.  It was particularly interesting to me because it became very apparent that he really had no idea of what he was talking about.  What is more interesting and the point of this post is that Dr. Chartock is the CEO of Northeast Public Radio and thus should have a thorough understanding of the technology he is promoting.

He began by saying that most broadcasters where rushing to install IBOC (HD radio®) equipment.  According to the FCC.gov web site, there are currently 1,542 FM stations out of 9,630 total FM stations broadcasting in IBOC.  That represents approximately sixteen percent, which is a rather low number.  Further, many of those stations are National Public Radio member stations which received very generous grants from the Corporation for Public Broadcasting (e.g. your tax dollars) to purchase and install the said digital radio equipment from the sole manufacture and licenser of IBOC radio in the US, Ibiquity.  Incidentally, there are 292 out of 4,790 AM stations currently broadcasting in IBOC, or roughly six percent.  Those numbers have been relatively static over the last several years.  It could hardly be called a rush to install.

I have a distinct problem with this scenario.  As Keep public radio public noted:

It is categorically wrong for public money to be used to subsidize a monopoly such as iBiquity, proprietary licensor of HD radio. Millions of dollars of funds from the Corporation for Public Broadcasting have been used to promote the spread of HD radio by grants to local public radio stations for conversion to a substandard IBOC system, which not only fails to deliver on claims of superior quality but also interferes with signals from adjacent stations. Even FCC Commissioner Michael Copps admitted, “Everybody involved pretty much admitted from the outset that the digital radio initiative is all about giving the broadcast industry more avenues to make money rather than actually improving radio from the perspective of the listener.”

Secondly, Alan stated that there is no analog radio anymore, “It’s all digital.”  Nothing could be further from the truth.  I suspect that Dr. Chartock is simply ignorant of the technology in spite of his title as CEO.  That, in a nutshell, is the problem with IBOC technology.  No one in a position of authority seems to understand what it is all about.  While the technical spec looks better for main channel IBOC vs. analog FM if one is considering total frequency response only.  Unfortunately, to attain that 20 kHz spec, some very aggressive bit reduction is required to make the digital signal conform with the alloted bandwidth.  A well designed and maintained analog FM station will sound as good as any IBOC signal out there.  Add to that, the difficulty receiving the IBOC signal in mobile environments or lack of building penatration of the IBOC signal, and the digital carrier is far inferior to the analog stereo system that has been in use since 1961.

Most broadcasters see it as an opportunity for second program channel on the HD-2 carrier.  While that is one advantage of the technology, doing so means a revenue sharing agreement with Ibiquity.  If the main channels use aggressive bit reduction schemes, the second and third channel use bit reduction butchery.  If the audio quality of Sirius Satellite radio sounded bad, this sounds worse.   The quality of such secondary data streams is so low and I would think that organizations such as NPR and CPB, both of which pride them selves on the quality of their product would not want to degrade it thus.

Finally, IBOC (HD radio®) is not the same as HDTV.  On the TV side of things the HD stands for “High Definition.”  This notes an actual improvement to TV technology by increased picture size and screen definition.  On the radio side of things the HD stands for nothing, it is merely two letters that Ibiquity chose to represent its IBOC system.   The fact that the letters are “H” and “D” is a coincidence.

IBOC update

Since the FCC approved a ten fold increase in the radiated power of the digital carrier, a progress report on the digital radio rollout is in order.  The FCC report and order (MM Docket No. 99-325) gives us some background:

An original goal of the developers of the hybrid FM IBOC DAB system was replication of FM analog coverage without adversely affecting either the host analog signal or adjacent channel analog FM operations. iBiquity and several independent parties conducted extensive field and laboratory tests. Based on the National Radio Systems Committee (“NRSC”) evaluation of those test results, iBiquity requested and the NRSC approved an FM Digital ERP of one percent of FM Analog ERP (20 decibels below carrier (-20 dBc)).

And (after paying gobs of license fees and installation costs):

Many FM stations promptly commenced hybrid FM IBOC operations. Despite the rigorous testing, it soon became apparent that hybrid FM IBOC digital coverage often did not replicate analog coverage, especially in mobile and indoor environments.

Therefore (Fox, here are the keys to the hen house, knock your self out):

Based on the results of the experimental operations with increased FM Digital ERP and other studies, on June 10, 2008, a group consisting of 18 radio group owners that operate over 1,200 commercial and noncommercial educational (“NCE”) FM stations and the four largest broadcast transmission equipment manufacturers, identifying themselves as “Joint Parties,” requested (the “Joint Parties Request”) that the Commission generally increase maximum permissible FM Digital ERP10 from one percent of a station’s authorized analog ERP (-20 dBc) (1% FM IBOC Power”) to a maximum of ten percent of a station’s authorized analog ERP (-10 dBc) (“10% FM IBOC Power”).

Based on (We find these hens are delicious!):

NPR concluded that at 1% FM IBOC Power, the mobile, indoor and portable digital coverage achieved by most FM stations would not replicate analog coverage, but that at 10% FM IBOC Power most FM stations could achieve digital mobile, portable and indoor coverage levels which either met or exceeded comparable analog coverage levels.

And (in spite of numerous concerns by the public and other broadcasters) Viola:

73.404 Interim Hybrid IBOC DAB Operation.
(a) The licensee of an AM or FM station, or the permittee of a new AM or FM station which has commenced program test operation pursuant to § 73.1620, may commence interim hybrid IBOC DAB operation with digital facilities which conform to the technical specifications specified for hybrid DAB operation in the First Report and Order in MM Docket No. 99-325, as revised in the Media Bureau’s subsequent Order in MM Docket No. 99-325. FM stations are permitted to operate with hybrid digital effective radiated power equal to one percent (-20 decibels below carrier (dBc)) of authorized analog effective radiated power and may operate with up to ten percent (-10 dBc) of authorized analog effective radiated power in accordance with the procedures set forth in the Media Bureau’s Order in MM Docket No 99-325. An AM or FM station may transmit IBOC signals during all hours for which the station is licensed to broadcast.

Notice how they stuck AM nighttime operation in there too.  Now I get to hear IBOC signals over riding adjacent channel stations that used to come in clearly via skywave.  One tends to wonder if this interference is not deliberate.  Crush the small operators with interference, make their stations worthless, drive them out of business…

To help things along, iBiquity has offered to reduce their licensing fees to $5,000.00  (oops, its more like $10,500 – 12,500). These rules were put into effect on January 29, 2010.  According to the FCC data base, there are 1524 FM stations and 292 AM stations transmitting IBOC.  That breaks down to 15% of the FM stations and 6% of the AM stations.  I will post an update if there is a sudden rush to install IBOC. Still a pretty low penetration for a 10-20 year old technology.  It is likely these low numbers are the reason why both broadcast bands are still mostly listenable, at least from a technical perspective.

As the noise floor rises and the competing stations sink further and further into the mud, the audience will turn to non-static filled technologies to listen to their music and other programs.

Why am I not surprised

NPR and iBiquity has come to an agreement to screw the rest of us out of radio spectrum with a four fold increase in HD RadioTM power levels. Here comes the interference.

But hey, it’s the future, that digital stuff, because it’s better.  And if you are not on board, then you are a narrow minded backwards thinker not worthy of consideration.

The funny thing is, all of the bells and whistles and whiz bang digital do dads, Ipod song titles, and fancy acronyms do not add up to a nano fart.  If there is nothing compelling listeners to buy the HD Radios,TM it is a dead technology.  Here is a news flash, when it comes to radio listener ship,


That has to be fixed, then the other stuff will start to make sense.

What do I know?  I’m going to go have a cold beer and put my feet up.
