 Tele/Conferencing

Linking People Together Digitally (2010)

A humorous example of a face-to-face (F2F) meeting.  People say they prefer F2F but when you consider all the issues in human communications, then consider how communication changes in a tele/presence meeting.  It's not that tele/presence is that great, it's that F2F are generally not that great either.

Facing CODEC Conundrums* & Challenges  
The range of human hearing is from 20-20,000 Hertz lowering with age to 12-14,000 Hertz.  Radio, power and audio frequencies are measured in hertz.  A Hertz is also known as a cycle and though not always is the same as bits per second and audio.  
 
A traditional POTS-Plain Old Telephone Service telephone line is 300-3,300/3,800 Hertz (cycle) bandwidth or sampling rate of 4 KHz (kilo Hertz) or Shannon/Nyquist theory of twice the bandwidth into eight bit (byte-octet) samples or 4,000 x 2 x 8 bits = 64,000.  
 
 
 
Before we explore Wideband CODECS, let's review common CODECS used in SIP or IP Telephony.  G.711 and G.729 are the two commonly used CODECS for voice. 
 

Wideband Audio also known as HD-High Definition Audio is not limited to the bandwidth restrictions of traditional PSTN-Public Switched Telephone Network circuit switching of 64,000 or 64 KBPS-Kilobits Per Second.   
 
LBR-Low Bit Rate CODECs-Compression-Decompression emerged with advances in technology for wireline and wireless networks to add more calls on the same circuit.  G.722 at 16 KHz (note: twice traditional 8 KHz), G.722.1 standard is limited to handsfree operation and low packet loss conditions, and G.722.2 (AMR-WB-Adaptive Multi-Rate-WideBand) for both wireless ETSI/3GPP and wireline services using 6.6-23.85 KBPS.  One of the many conundrums is what CODEC to pick today to design both an internal corporate network and one that can be interconnected with others.

Future Outlook, look for:

- Demand for higher fidelity integrated with video

- Applications in entertainment (color ring-back tones)** 

- Wideband and "super wideband" multi-media mobile

- Virtual reality - "super tele/presence"

- Continuing advancements in algorithms and modeling

Challenges & Conundrums*

- QoS from networks, asynchronous transcoding and other  system

- Interconnection and interoperability with IMS-IP Multimedia

      Subsystems and Peer-to-Peer networks

- Ability to convert "on the fly"

- More coders and more mobile applications

- Competitive interoperability and business interconnectivity

- Yet to be determined factors
 
------------------------- 
**Here's an example of Wideband Color-Ring-Back Tones-CRBT

1 - Caller dials a CRBT service subscriber.
2 - Incoming call initiates IN-Intelligent Network and routes the call via SS7-ISUP-IAM to the CRBT server via the SCP-Service Control Point.
3 -  CRBT server generates color tone which is sent to the caller via SS7.
4 - CRBT tone server dials the called party via SS7-ISUP-IAM "tromboning" on another SS7 link.
 
In addition, explained in the animated tutorial is Pulse and Hertz are related though terminology often differs.  This is a Pulse.  The parts of the pulse include the rise time, fall time, and pulse width, pulse amplitude. The period of a pulse refers to the amount of time between pulses.
 
In coming issues of this Tele/Presence Forum Newsletter, we will explore the delays and issues related to customer acceptance of tele/presence and the changing landscape moving forward.

 "TelePresence Immersion" in 60 Seconds       click here

This is a demo of Cisco's CTS-1000 in less than a minute to give you an idea of what "immersion" video tele/presence is all about.  The person on the screen is Tim Szigeti one of the authors of Cisco TelePresence Fundamentals (mentioned above) book which is included free to all attendees at the Tele/Presence Forum Expo.
 
Tim explained in a longer interview conducted via telepresence (coming soon in this newsletter) the three key qualities of Cisco's telepresence strategy:
- Reliability - not just "n-point" reliability but all points - signaling, network, room, firewall, XML, Outlook reliability to anticipate and eliminate all problems
- Simplicity - "one button touch" access and scheduling via Outlook
- Quality of Service - not just high-definition audio and video but spatial audio.

 The Developing an Intercompany Telepresence & Visual Collaboration Program Conference and Working Group
