HD VS. SDCan you spell that phonetically?
Audio Sample SD = Standard Definition Or Toll Quality (AM radio quality)
Audio Sample HD = High Definition (FM radio quality) No need to spell any word or
name phonetically

CPU & BW “Constant”
High Sampling Rate
Higher Compression
Higher available CPU Power
Low Sampling Rate
Low Compression
Lower available CPU Power
G.711 – 64Kbps – SD G.722 – 64-48Kbps – HD
About thesame data rate & cost

Protocols
How do protocols affect HD proliferation
www.phone.com
The VoIP foreplay PSTN Protocol
Ring, I can do HD, SD, and how are you today?
Fine thank you. HD it is.
Or, I can do HD but my network is congested.
Or, I am running out of battery lets use SD.
Ok, let me know when you have the BW and we can switch to HD
SIP Protocol
Ring
Talk

With negotiation enabledthe sky is the limit.
New technology can be deployed unilaterally As more devices get it, utilization grows Consumer quality-perception rise Perceived value increases People now have FEW compelling reasons to switch
The network effect The more people own an HD phone, the more
valuable the HD phone is to each owner.

Almost there…
We have the voice technology We have sufficient Bandwidth We have sufficient CPU power We have free HD Codecs
But, friction still exists

The PSTN friction
Calls To, From and Via PSTN, reduce the quality

The Tipping Point As Cellular devices support native
HD VOIP and VOIP Addressability
Billions of devices will suddenly become HD capable
Networks will adopt, or diminish
Not to have an HD phone will be impolite
HD will become a reality
www.phone.com
How Can We Accelerate
Phone.com is HD connected to Voxbone G.722
Voxbobe is HD connected to Skype SILK
France Telecom is experimenting HD cellular WMR-WB
HD Peering is inevitable – But who will do the transcoding?

Expected Transcoding Cost

Stage
Initial - early adopters
More Adoption
Lower Cost CPU Power
High Adoption - Less Transcoding

My Suggestion
G.711, G.722, SILK, are all free
Persuade patent holders to license AMR-WB for FREE! to peering fabric providers.
Eliminate extra cost associated with Codecs Accelerate the network effect Sell more licenses to end points
