... a beer, that is free as in speech !

... if ”openness” makes sense for a beer,
it should also make sense for other things ...

Problem with that phone:
no broadcast applications except:DMB and DAB audio
missing key broadcast applications:Slideshow, broadcast website, TPEG, ...
No open API to access raw bit streams
![Page 13: Open Mobile Broadcasting Phones](https://reader034.fdocuments.us/reader034/viewer/2022051323/547b713db37959a22b8b4d13/html5/thumbnails/13.jpg)
Why is it like that ?
manufacturer did not have time to implement ?manufacturer did not want to increase royalties burden ?
applications on phones selected by telcos ?broadcast and telco applications are competing?
telco business models different than broadcast (FTA)?unlike PCs, mobile phones live in a vertical ecosystem?
![Page 14: Open Mobile Broadcasting Phones](https://reader034.fdocuments.us/reader034/viewer/2022051323/547b713db37959a22b8b4d13/html5/thumbnails/14.jpg)
As a consequence:
we can't create new applicationswe can't improve the functionality
we can't create extensionswe can't participate to innovation on top of...some business models get excluded (FTA)
...

So let's just build a FREE/OPEN mobile phone !

No stack has mobile broadcasting ! ?

this prototype shows that:
a broadcast sw stack can be built relativelyeasily inside the openmoko framework
other missing apps could be added as easily

KEY ISSUE:
identify chipset maker willing to embraceopen source buniness models
![Page 31: Open Mobile Broadcasting Phones](https://reader034.fdocuments.us/reader034/viewer/2022051323/547b713db37959a22b8b4d13/html5/thumbnails/31.jpg)
Other ISSUES:
Legal (Licenses, patents, copyrights)
Open Standards (degree of openness)

CRC tools (based on open source)
to help build
NEW MMB APPLICATIONS ...

THERE IS HOPE:
some do start to understandthe power of open source models
to sell silicon (TI)

Some Conclusions
CRC has produced tools for collaboration(an architecture of participation?)
We invite MMB chipset makers tothink about open source business models
CRC releases CRC-DABRMS for free
Broadcasting should become a moreorganic ecosystem (Internet model)
Broadcasting in a phone makes sense:”CONVERSATION IS KING”
