Re: First AAC/AAC+ radio services launched on T-DMB?

The core of the problem is that this is not a technical problem. It is
an economic problem.

If nine services can be provided on a multiplex at 128 kbps MP2 (PL3), or 18 at 64 kbps AAC, which one do you think is more economical?


In essence, there are two issues:
- Digital broacast as -compaired to analog broadcasting- a lot more
"knobs" you can tune, but .. doing so a much larger direct economic
impact on the cost of the service.

That is why I would like regulations. On all issues regarding broadcast quality.

This means that -freeriding services- that ride on-top of another
service but had no or little economic cost (like stereo) now are not
"free" anymore.

Stereo is not exactly free by the way, it needs a considerably higher signal strength. But I can guess what you mean.

- The more services you make available (additional services, even
subscription-services), the more competition there is for the
radio-stations and this eats away on the revenue of the radio-stations.


Regulation again. Just have stations use minimum quality levels and require a certain part of a multiplex to be used for free-to-air services.

Now, it may be possible to reduce the transmission-cost for a station by
using digital technology, but that does not turn to be enough to
compensate for the loss of revenue.
(because advertisements represent almost the complete revenue-source for
a station while transmission-cost only represents a part of the costs of
a radio-station).

AAC is a way to lower transmission cost. Digital radio will bring no extra revenue for years after starting it up.


Actually, you make it worse, as the sollution you propose (more
efficient codecs) actually amplify the effect of issue 2 (more stations
-> more competition -> less revenue per station).

An efficient codec could be used to provide more services, but it could also be used to provide higher quality, or anything in between. Transmitting at 128 kbps AAC would cost the same as broadcasting at 128 kbps MP2.
