Creating Smarter & Greener DOR’s

& Integration Of Equipment To Increase Energy Efficiency.

4K - What to expect

Ivan van Rensburg

DOR / MMT as we Know it…

Additions Come Systematically one by one… Central user Interface

Multiple user interfaces Signal Management

New Signal types Device Control

New devices Data management

Addition of New Devices Integration ?

Lights,HVAC,Devices, etc.

Ability to adapt

GUI Signals Devices DATA Integration INTEGRATION!!!!!

Integration

Lights Occupaciency sensor, Lux sensor, ambient

light HVAC

Circulation and Temperature control UPS Solar Water Gas Alarms

Smarter DOR

Smarter Lighting control – with Override Smarter device control - with Override Customizing Scheduling Active feedback Remote notification. Communication BMS Integration

4K Video – Color Space evolution

16.78 million colors (8 bit) 1 billion colors (10bit)68 billion colors (12bit)

Bandwidth Requirements

Pixel Clock: The time base in MHz at which individual pixels (picture elements) in an image are written to the screen.

Bandwidth: The capacity required in MHz of a given system to pass a specific frequency

Data Rate: The data flow throughput in bits per second of the transport layer.

Bandwidth Requirements

Pixel Clock (MHz) #horizontal pixels * #vertical lines * refresh rate Always includes blanking Pixels

•Data Rate (Gbps) Pixel Clock * Pixel Size (in bits)

•Line Rate (Gbps) Data Rate + 25% (overhead) 8b/10b encoding Divided across 3 channels

Bandwidth Requirements

Pixel Clock of 1024x768@60Hz 1328 pixels across (304 are blank) 798 lines down (30 are blank) Pixel clock (MHz) #horizontal pixels * #vertical lines * refresh rate

1328*798*60 = 63.58MHz

Pixel clock of 1920x1080@60Hz 1920x1080@60Hz 2200 pixels across (280 blanking) 1125 lines down

(45 blanking)

2200x1125x60=148.5MHz

Bandwidth Requirements

What is the Pixel clock of 4K? 3840x2160@24Hz 5500 pixels across (1660

blanking) 2250 lines down (90 blanking)

5500x2250x24=297MHz

Bandwidth Requirements

Bandwidth Requirements

Pixel Clock for 1080p @ 60 1920x1080@60Hz

2200 * 1125 * 60 = 148.5MHz

•Data Rate for 1080 @ 60 (12 bit color) 36bits * 148.5 Mpixels/second = 5.34Gbps

•Line Rate Data Rate * 1.25 5.34Gbps * 1.25 = 6.78Gbps

Bandwidth Requirements

Pixel Clock for 4K @ 30 3840x2160@30Hz

4400 * 2250 * 30 = 297MHz

•Data Rate for 4K @ 30 (8 bit color) 24bits * 297 Mpixels/second = 7.12Gbps

•Line Rate Data Rate * 1.25 7.12Gbps * 1.25 = 8.91Gbps

Pixel Clock for 4K @ 60 3840x2160@60Hz 4400 * 2250 * 60 = 594MHz

•Data Rate for 4K @ 24 (8 bit color) 24bits * 594 Mpixels/second = 14.25Gbps

•Line Rate Data Rate * 1.25 14.25Gbps * 1.25 = 17.81Gbps
