& 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
