2. Presentation Outline
• Why do we require Standards?
• Video Coding Standards-Evolution, Present Status & IPRs
Technology enhanced services for masses
• Technology Enhanced Learning
• Telehealth
Unique Opportunities

3. A World without Standards
• Products might not perform as expected
• Incompatible with other equipment
• Risk from Non-standardized products
• Restrictive Market & Diffusion
• Inferior quality products
Non-Interoperability has a huge impact on
sound functioning of future services esp. in
Industry 4.0

4. Standards facilitate
• Interoperability
• Inclusivity
• Innovation
• Integration of services
• Increased market
• Trustworthiness
• Development
• Increase awareness of
technical developments
and initiatives
“Standards should facilitate
interoperability, support fair
trade and fair competition,
increase user, consumer and
government confidence and
stimulate innovation”
-Karen Bartleson in ‘The Ten
Commandments for Effective
Standards – Practical Insights for
Creating Technical Standards

5. Technical Standards
• standardization enable in:
• mobile communication technology and its
successors (3G, 4G,5G...),
• IEEE 802 LAN standards, including 802.11
WLAN standards (WiFi)
• ITU-T H.261 digital video coding standard and
its successors (H.263, H.264, H.265, …)
• JPEG

6. Video Standards creates a
Global Stage
•Video accounts 80 per cent of all
consumer Internet traffic.
•World’s three leading standards
bodies viz. IEC, ISO and ITU.

Annual global IP traffic will reach 4.8 ZB
per year by 2022, or 396 exabytes (EB)
per month.

7. Video Standards creates a
Global Stage
• Growth of Social Media Networks, Handheld
smart devices with high processing capabilities
and high resolution cameras
• YouTube, Facebook, Instagram, etc.
• Netflix, Amazon Prime Video, Hotstar, etc.
• Next few years, the era of 4K and 8K devices, will
see the newer video coding standards with even
higher compression rate
UHD (or 4K) video will
account for 22 percent of
global IP Video traffic by
2022
400 hours of video are
uploaded to YouTube every
minute

8. Video Format
•Container (AVI and Quicktime MOV etc.)
•Video and audio signal
•Codec: encode and decode the video & audio
signal
•Metadata
One of the most versatile codec families in use today is
H.264. (H.264 is also called MPEG-4 Part 10 and AVC)

9. Videos
• Frame size: pixel dimension of the frame
• Aspect Ratio: ratio of width to height
• Frame rate: playback speed of frame
• Bitrate: amount of data used to describe the audio or video
portion of the file. higher the bitrate, the better the quality
From VGA (640x480 resolution) to HDTV (1920x1080) and
4K(3,840x2,160) and 8K

10. Videos
• Bit rate for 4K video at about 15 to 18 Mbps is more than
double the HD video bit rate and nine times more than
Standard-Definition (SD) video bit rate.
• By 2022, nearly two-thirds (62 percent) of the installed flat-
panel TV sets will be UHD, up from 23 percent in 2017

11. Video Coding Standards - Evolution
1993:MPEG 1
1994:MPEG 2 (High
Quality DV)
1999:MPEG 4 (Very
Low-bitrate coding for
multimedia and
internet
2003:H.264 / AVC
(Internet, C, Mobiles,
HDTVs)
2010:VP8 (Google's
initiative for new
compression standard)
2013:H.265 / HEVC
(UltraHDTV upto 8K,
50 % improvement
over H.264)
2013:VP9 (Performs at
same level as H.265)
2015:VP10 (Alliance
for Open Media - AV1
Codec development
begins)
2018:AV1 ( commercial
applications
development allowed)
2018:VVC (Versatile
Video Coding-
VCEG+MPEG, final by
July 2020)
2019:AV1 finalised
2019:MPEG5 (LCEVC
draft specs)

12. Video Coding Standards-Latest Work
• In 2014 MPEG began work on next generation video coding standard -
Future Video Coding (FVC).
• In April 2018, evaluation of the proposals received and first draft of the
standard was formulated. ISO/IEC 23090 MPEG-I Part 3 Versatile Video
Coding (VVC).
• VVC aims to support three types of video: Standard Dynamic Range (SDR),
High Dynamic Range (HDR), and 360° (VR-oriented, omnidirectional view)
with objective to achieve better coding efficiencies and versatility through
Screen content coding, reference picture sampling & independent
subpictures

13. Video Coding - Royalty Bearing & Royalty Free
• Royalty-bearing codecs (e.g. MPEG) have always been the gold
standard
• The Alliance for Open Media (AOM), founded by Google, Cisco,
Amazon, Netflix, Intel, Microsoft, and Mozilla, aims to combine
their technological and legal strength to ensure the development
of a next-generation compression technology (for royalty-free
video codec ) that will be both superior in performance over
HEVC and free of charge

14. Video Coding – Latest Work
To Address the Problem of HEVC royalties, delayed deployment
• Alliance for Open media took initiative
• Came out with AV1: Royalty free codec, applicable for broadcast
& Optimized for OTT
• HQ and real time delivery modes
• Compression gains of ~25% over current codecs
• Low to High Res (UHD, HDR, WCG)

15. Video Coding Standards- IPR - Standard-
Essential patent
•A Patent that protects the technology essential to a
Standard is called a Standard-Essential patent (SEP)
•Licensing pools - A common way to License the SEPs e.g.
MPEG-LA , HEVC Advance, Via

16. Video Coding Standards- IPR - Standard-
Essential patent
• Standard setting organisations(SSO) ensure that the exclusive rights are
granted in their standards only to companies that warrant them and
need RoI to develop next generation technologies
• Licensing on Fair, Reasonable and Non-Discriminatory (FRAND)Terms

17. Technology enhanced
services for masses
• Technology Enhanced Learning
• TeleHealth
• Web RTC

18. WebRTC (www.webrtc.org)
• WebRTC offers web application developers the ability to write
rich, realtime multimedia applications (think video chat) on the
web, without requiring plugins, downloads or installs.
• Includes the fundamental building blocks for high-quality
communications on the web, such as network, audio and video
components used in voice and video chat applications.
• These components, when implemented in a browser, can be
accessed through a JavaScript API, enabling developers to easily
implement their own RTC web app.

20. Unique Opportunities
• Challenge is to achieve compression efficiency by keeping in
mind the computational efficiency also.
• Surveillance Applications
• Video Analytics
• Machine Learning
