HD Innovations Panel – Part I
- Moderator, Robert Messer, Pres, ABP Tech; Panel, Alan Percy, AudioCodes Ryan Heidari, Qualcomm, Tobias Kemper Nimbuzz
- Kemper – Working on building market for HD, challenge telling mass market you can make SIP’/HD calling
- Percy – “Father in law test” Need to be easy/transparent, educate consumers, need to be simple, simple, simple
- Heidari – Need one common codec, guarantee call won’t drop; G.722 seems to be acceptable Downloadable codecs possible in future.]
- Keidari – (downloadable as in on-the-fly downloading of codec into phone if it’s not there..)
- Percy – Skeptic of downloadable codec; recites Adobe Reader experience of downloading, crashing, updating.
- Q – What innovations happening in transcoder space?
- Percy – Ability to quickly support multiple coders on DSPs, switch coders quickly, also do at 2x sample rate
- Percy – Looking forward, not endpoint yet, just starting to learn; Moving from G.722 to AMR-WB, get losses, but are ways to mitigate loss
- Heidari – Mixing of multiple codecs people don’t want to handle, add delay of 30-40 milliseconds.
- Percy – Horse out of barn, wireless and wireline and Microsoft already chosen codecs, have to transcode in Real World.
- Nimbuzz – chose open source common ground
- Q- Where is innovation going – Bluetooth headsets, etc – for HD capable gear
- Heidari – Bluetooth HPF, SPC codec, 5 other codecs optionality, problem with Bluetooth is low-powered device, can’t handle complexity of HD
HD Innovations Panel – Part II
- Moderator Ben Lillenthal, VAPPS; speakers Jim Toga, Vivox, Tim Panton PhoneFromHome, Richard Romagnino VoiceAge
- Panton – Turn PC into G.722 device thorugh web-based interface
- Toga – More to voice than just the interface
- Toga – Quality control, content, people using apps, providing communication mechaniims. 2B million A MONTH of wideband minutes
- Toga – Vivox provides voice in Second Life,
- Toga – Voice should be seamless part of app
- Romangnino – setting up wideband pool for licenses in AMR-WB , help licensing issues
- Romangingo – Never get ride of transcoding, but a goal to work to. Transcoding intros delays, artifacts
- Toga – Voice is a “keeper” when it comes to stickier on a for-fee service;
