I’d suggest a royalty free path to the TV might be shorter than might be apparent.

Indeed, the article certainly doesn’t say or imply that the MPEG-4 video codec is royalty free, it most certainly is not — as described in the previous post on Sun’s OMS Video draft at http://www.robglidden.com/2008/12/oms-video-draft/.

But Brazil has eliminated an even larger chunk of royalties in the transmission and interactive layers. Royalties on transmission (”$5.00 for each ATSC Receiver Product”, see http://www.mpegla.com/atsc/atsc-faq.cfm) and the interactive layer described in the article (MHP is $1.75 and $1.25 per subscriber household, see http://www.vialicensing.com/licensing/MHP_fees.cfm) can be more than an MPEG-2 codec ($2.50 per decoder, see http://www.mpegla.com/m2/m2-agreement.cfm) or lower-priced patented codec like MPEG-4, AVC, H.264 etc (see http://www.mpegla.com).

So component by component, the path to royalty-free is clearer than ever, and Brazil has intelligently and pragmatically moved a significant way along it. A future deployment choosing one of several royalty-free (or significantly lower-priced) codecs, well that might be unthinkable to a certain patents-are-forever status-quo … but …

Using ISDB still requires a royalty to be paid to MPEG-LA for the MPEG-4 video codec. The myth of a royalty-free DTV system is just that — non-existent.

The work carried out in Brazil was a process of rethinking Digital TV in a way that it could actually become what everyone expects of it, without loosing what makes television great for viewers. This could only be done by addressing the barriers imposed to DTV implementation by royalties and licenses, while still respecting intellectual property rights.

Your article is a good summary of the accomplishments made by the team responsible for designing SBTVD standards and regulations. It’s also proof that there might be something to gain when rethinking old solutions over the light of new ideas.

Bright article, Rob. It really describes most of the complexities and the exposure related to the adoption of royalty – encumbered technologies
