Only 47 years ago , on 29 October 1969 ,the first message was sent over the ARPANET, the predecessor of the Internet.

In retrospect ATM machines
were one of the first IOT
devices in 1974.

“1999 , British entrepreneur Kevin Ashton used the term Internet Of Things, while
working at Auto-ID Labs (originally called Auto-ID centers, referring to a global network
of objects connected to radio-frequency identification, or RFID).

Streaming Multimedia Content in IOT over Open
source Standardized Media Stack ( WebRTC )
Streaming Event data and Multimedia
With IOT , machinery in plants , industries , motor vehicles,
smart cities have sensors emitting enormous streams of
data in real time.Media capture devices ( surveillance cameras , scanners ,
readers ) and user agents ( smartphones, watches ,
desktops , appliances , kiosks ) can stream audio /video
data.
next generation of applications will see, hear and understand.
Why is WebRTC suited for handling media streams in IOT ?
No plugins No installations of flash or any other 3rd party plugins
Royalty free codecVP8 , VP9 , OPUS MIT , GPL
Rapid SupportCommunity support and adoption by major browsers, native SDKs
JavascriptSupport for js is the key to making it easily adoptable by developers

Media codecs
● Licensed codecs like flash by
adobe , H264/H264/MPEG by
MPEGLA cannot be freely
used .
● Open source media stacks
(webrtc ) not supported
everywhere.
● Realtime transcoding is very
taxing .
Bottlenecks for Media streaming in IOT
Proprietary protocols and standards
● IMAP , ICMP , Parley , SOAP ,
GIOP , Javs RMI , IMAP , LDAP
and many more .
● Telcos use proprietary patented
communication protocol stacks
too
Supporting all mobile OS and web browsers
● Lot of time and resources are
spend on user interface design
● Support and rendering on multiple
end- user devices .
● NAT and Firewall issues
Any questions?
