7. When Worlds Collide: The Blurring Lines of Real-Time and Traditional Media
8. Firstly, Some Definitions Are Needed
9. What Types of Media Are There?
10. Real-Time
11. Traditional Media
12. Live
13. Video on Demand
14. The Lines Are Blurring
15. All Thanks to the P Word
16. PANDEMIC
18. Providers Offering all Round Integration
19. We've Seen CDN Providers Getting Into "Real Time"
22. And We've Seen Real Time Providers Wanting Not-So-Real-Time
24. So Where Do We Go From Here?
25. I've Been in Real Time Media for Over 10 Years.
26. And Theres Definitely Been a "Us and Them" Feeling.
27. "We Do Real Time"
28. "You Call That Real Time?!"
29. Two Industries Divided by Definition
30. Bing Image Creator
31. Bing Image Creator
32. By "Quality"
33. Bing Image Creator
34. By "Latency"
35. Bing Image Creator
36. By "Technology"
37. Bing Image Creator
38. Both Industries Might Both Be "Media"
39. But the Understanding Required Is Very Different
40. Real-Time = WebRTC & SIP (Yes, I know... I haven't forgotten about RTP/SRTP)
41. Traditional Media = Egress - HLS / DASH Ingress - SRT / RTMP
42. The Technologies Used Result in Differing Qualities and Latency
43. Latency
44. Real-Time = <500ms
45. The Human Brain Can Cope With ~300ms Delay
46. Traditional Media = >500ms
47. But Usually More Like 5-10 Seconds!
48. HLS/Dash Is TCP WebRTC Is UDP
49. Losing an RTP Packet Is OK
50. Losing a HLS Chunk... Not So Much
51. Ultimately... The Technologies Are Vastly Different
52. RTP != HLS
53. RTP != DASH
54. "HLS Is Just HTTP"
55. That's Far From the Truth
56. And We all Know RTP Isn't Simple
57. The Blurring of the Lines
58. Two Potentials Blurring Those Lines in the Near Term
59. WHIP / WHEP
60. WebRTC HTTP Ingest Protocol
61. WebRTC HTTP Egress Protocol
62. WebRTC Didn't Have a Signalling Protocol
63. You Could Use SIP
64. Or XMPP
65. Or Your Own Custom "Thing"
66. But the Encoder/ Decoder Vendors for "Traditional Media" Wanted To Implement "How To Talk WebRTC" Once
67. Now You Can
68. With WHIP and WHEP
69. Which Means We're Now Getting WebRTC Adoption in "Traditional Media"
70. But We've Also Got QUIC on the Horizon
71. QUIC Has the Chance of Redefining How We Transport Media
72. A Common Transport for all
73. And Potentially a Common Specification
74. Media over QUIC https://conferences2.sigcomm.org/co-next/2018/slides/epiq-real-time_audio-visual_media_transport.pdf
75. One Common Spec To Rule Them all
76. Real Time? VOD? Live?
77. It Doesn't Matter
78. Does This Mean the End of WebRTC?
79. No
80. Does It Mean More Choice?
81. Absolutely
82. Does It Mean More Value Add?
83. HECK YEAH
84. Which Means More Business Opportunities
86. And That's Only a Good Thing
87. A Hugely Exciting Time To Be in the Media Industry
88. Whether It's Real-Time or Not
89. Thanks for Having Me!
90. Thanks! nimblea.pe everycastlabs.uk broadcastbridge.app commcon.xyz @dan_jenkins @danjenkins@fosstodon.org
