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 • 8 K • 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
