7 reasons why video conferencing world will never
0 likes•1,710 views
The video conferencing world will never be the same again due to several technological trends: 1. Advances in CPU technology allow for higher quality video encoding and decoding on regular computers and mobile devices. 2. Scalable video coding allows a single system to replace traditional MCU infrastructure, supporting multiple resolutions from SD to 4K without transcoding. 3. WebRTC enables real-time communications directly in web browsers without plugins. 4. Interoperability standards like SIP allow different video systems to connect with one another. 5. Consumerization trends like mobility, BYOD, and wireless interfaces are influencing enterprise video conferencing.
7 reasons why video conferencing world will never
- 1. 7 reasons why video conferencing world will never be the same again Dmitry Odintsov, TrueConf
- 2. 1. Moore Law
- 4. • Regular CPU can encode 1080p • Regular CPU can decode many 1080p • CPU based solutions become cheaper than DSP
- 5. Video Conferencing Endpoints Rooms PC Mobile EmbededWeb 1x Screen 2x Screens 3x Screens - Immersive Software 2010 VC Infrastructure Software 2015 SmartTV Kiosk Call Center
- 6. Infrastructure: Downloadable, Virtual or Cloud Upgradable No Capital Costs Easy Evaluation Scalable Free!
- 7. Clouds and Security • Fast. Convenient. No headache. Accessible. • No guarantees. Unstable channels. Privacy Issues. • Balancing between comfort and security. • Perfect Cloud costs more than On Premise.
- 9. Outgoing 720p Incoming 720p MCU 1. Decode every incoming stream 2. Mix stream 3. Encode output stream 4. Re-encode output for every user Delays! Quality! Old Mixing Approach
- 10. But transcoding is not required with SVC Scalable Video Coding H.264 SVC VP8 SVC Single PC can replace 100x MCUs!
- 11. SVC Optimal set for every peer: SD –> 4K Every try to send out maximum No transcoding :) Same bandwidth! Outgoing 720p 720p 1080p Fast Lossless New Scalable Architecture 720p 720p 720p 720p 360p 360p 360p 360p ∑=720p ∑=4K Flexible
- 13. 3. WebRTC Web Real Time Communications
- 14. Real Time Communications in Browsers? Browser ActiveX NPAPI Flash Java WebRTC Plugin / Additional layer ActiveX. Only for windows & only for Internet Explorer. NPAPI. Separate code for separate platforms. No IE support. Deprecated. Flash. Proprietary. Slow development. Poor video & audio. Java. Java Virtual Machine required. Exotic.
- 16. WebRTC. Instant On & Without Plugins
- 17. WebRTC Pros & Cons • No Internet Explorer support • No iOS support • Describes only one-on-one communications • Server / MCU required for multi-point conferences • Not really suitable for service providers • Users prefer to use native mobile apps. • 1 500 000 000 of desktops & mobiles on Earth are ready. • Compatible with Chrome-based browsers, Opera, Firefox. • Coded in JavaScript. Powered by of HTML5. • Built-in encryption & Firewall / NAT traversal. • Great video and audio codecs: VP8 + Opus.
- 18. 4. Interoperability = SIP
- 20. H.323 vs SIP SIP Only
- 24. 5. Hi-End Peripherals & Wireless Interfaces
- 25. POE USB
- 27. 6. Mobility / BYOD
- 28. • Powerful mobile CPU • Additional hardware encoders • Nice UI & cameras • Point of view (Bottom to Top) • 3G/4G Coverage • Battery usage
- 29. 7. VC is not AV anynmore. It’s IT.
- 30. Software combines all hardware features • Multipoint conferences • Scheduling • Presence Statuses & UC • Telephone & VoIP • Recording & Streaming • NAT Traversal • SIP / H.323 Registrar
- 31. Software Brings New Challenges to Sales • IT Team focus • Network and IT experience • How to Sell Cloud? • How to add more value (services, integrations) • Better customer care
- 32. What we should count on? • Video conferencing should be available at all times, not just in conference rooms. • It should be cross-platform. • It should be cheap and easy scalable. • It should be user-friendly, not engineer-friendly. • It should be able to connect guests. • It should be able to connect with other systems. • It should work via the Internet/satellite/3G, everything else. • And all that should not decrease quality!
