AVB Audio vs. Video
Audio is easy on Ethernet® AVB
1GbaseT = 300+ channels of audio
10GbaseT = 3000+ channels of audio
At 48 kHz sampling
Video – Not so easy
1 GbaseT = one compressed channel of video
10 GbaseT = 6 HD-SDI bistreams
= 3 1080p/60 “3G”
What about 4K video? 8K video?
Where is Ethernet Going?
10 gigabit copper
Available now
10GbaseT
625 MHz per pair
4 pair
100 meters
PAM 16
2 pulses v 256 only use 128
Where is Ethernet Going?
10G on fiber
10GbaseSR
850nm VCSL laser
Multimode /single mode (2 km)
10GbaseLR
1300nm
Single mode (10km+)
Where is Ethernet Going?
40 Gigabit Networking
Just approved on fiber
40GbaseT copper study group (Category 8)
Results by 2015
2 GHz per pair??
Overall foil shield/individual foil pair
Alien crosstalk +20 dB compared to 10GbaseT (Cat 6a)
4 pair??
30 meters??? (supports 90% of data center needs)
Where is Ethernet Going?
40 Gigabit Fiber
40GbaseSR4
VCSL laser
8 fiber = 4 lanes each direction
12-fiber
40GbaseLR4
10G x 4 lanes x 2 directions
Where is Ethernet Going?
100 Gigabit networking
Committee formed
100GbaseT
Probably beyond the capability of copper
100G Fiber
100GbaseLR10
25GHz per fiber
WDM 4 wavelengths
OR 10G fiber x 10 lanes x 2 directions = 20 fibers
Where is Video Going
HD-SDI
1.5 GHz clock
Occupied bandwidth 750 MHz (Nyquist)
Tested to third harmonic: 2.25 GHz
3G-SDI (1080p/60)
3 GHz clock
Occupied bandwidth 1.5 GHz (Nyquist)
Tested to third harmonic: 4.5 GHz
Where is Video Going
4K (in process)
10.6921 GHz clock (12 GHz)
Occupied bandwidth 5.346 to 6 .0 GHz (Nyquist)
Copper coax cable: not considered??
Tested to third harmonic : 16 to 18 GHz
Fiber – single mode
8K
No standards established
24 GHz clock? 12 GHz Nyquist? 36 GHz testing?

Multi Channel Digital Video
SMPTE work
20 Gb/s on fiber
Multiple 1.5 Gb/s HD bit streams combined?
Bit depth: 8-bit? 10-bit? 12-bit? 14-bit?
Coding: 4:4:4? 4:2:2?
How to Win an Emmy
Make these two work together
High-bandwidth Ethernet
High-bandwidth Video
Channel counts
256 x 256 video router now commonplace
128-port Ethernet switch is HUGE
Analog: Vertical blanking interval
How do you find a frame of video in Ethernet?
Who Wants AVB Now?
Automotive Industry
Less weight, simple networking
All sensors, camera, audio
2 ms latency is 2.5 inches at 70 MPH
Airline Industry
Light weight, simple networking
Multiple channel consumer video
