  1. Today’s Presentation: Digital Video At Length – Category Cables Your Presenter Today is… Brian Minchew, CTS Director of Sales and Business Development Email – bminchew@c2g.com

  2. Our Learning Objectives • Signals Important To Extended DV Connectivity? • Technical Challenges Of Long Connections • Basic Extension Of DV Using Category Cables • Understanding HDBaseT Technology And Applications

  3. “For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.” - Richard Feynman What Are The signals Being Sent?

  4. Digital Video • Color In Uncompressed Digital Video • 8-Bit Per RGB Component Minimum • Up To 4:4:4 Color Space With Up To 16-Bits Per sRGB Component • YCbCr 4:4:4 “Deep Color” • xvYCC Extended Gamut Color Space Support • Detail In Uncompressed Digital Video • Luminance Figure Sets Detail Level • D2K Is 2,000 Pixel Horizontal Measure • D4K Is 4,000 Horizontal Pixel Count By 2,000 Vertical Pixel Count • High-Bandwidth Digital Content Protection • Digital Copy Protection Developed By Intel Corporation To Prevent Copying Of Digital Audio And Video Content As It Travels Across Connections

  5. Digital Audio • HDMI Sources Support PCM And Other, Optional, Audio Formats • Up To 8-Channels Coded At 24-bits And 192khz Linear PCM • Up To 8-Channels Lossless Compressed DTS-HD • Up To 8-Channels 1-Bit DSD (Delta Sigma) Super Audio • Digital Audio Content Is Embedded Within The TMDS 10-Bit Data Stream • Audio Is “Embedded” Within The RGB Stream

  6. Consumer Electronics Control • CEC Is An HDMI Feature Designed To Allow The User To Control CEC-Enabled Devices • Via Device’s Remote Control(s) • Allows For Individual CEC-Enabled Devices To Command And Control Each Other Without User Intervention • One-Wire Bidirectional Serial Bus That Uses The Industry-Standard AV.Link Protocol • CEC Implementation Is Optional At The Product Level • CEC Standards Allow For USB-To-CEC Adapters For Custom Control Applications

  7. Display Data Channel • DDC Enables The Display To Communicate Its Supported Display Modes To The Source Using Inter IC Bus Protocol • I2C, Or Sometimes IIC • Extended Display Identification Data (EDID) Is A Companion Standard • Defines A Compact Binary File Format Describing The Monitor's Capabilities And Supported Graphics Modes • Stored In A Read-only Memory (EEPROM) Chip Programmed By The Manufacturer Of The Monitor • DDC/EDID Flows From The Sink To The Source

  8. Transition Minimized Differential Signalling • TMDS Transmits High-Speed Serial Data • Transmitter Incorporates An Advanced Coding Algorithm Which Reduces EMI Over Copper Cables And Enables Clock Recovery At The Rx To Achieve High Skew Tolerance • Uses 4 Channels: Red, Green, Blue, Clock • TMDS Is Natively Differential (Balanced) • Current Mode Logic (CML), DC Coupled And Terminated To 3.3 Volts. • 4 Twisted Pairs Are Used To Transfer Video And Clock Data

  9. “The shortest distance between two points is under construction.” - NoelieAltito The Challenges of distance

  10. The Physics Of Wire • Longer Wire = More Resistance • Cross-Sectional Area Of The Wires Affect Resistance • Material Composition Affects Resistance • Pure Resistance Causes A Frequency Independent Voltage Drop • Capacitance and Inductance Are Proportional To Wire Length/Construction • Impedance Is Defined As The Frequency Domain Ratio Of The Voltage To The Current • Parallel Conductors In Wire Express A Reactance That Is Inversely Proportional To Frequency • Capacitance and Inductance Cause A Frequency Dependent Voltage Drop • Skin Effect Becomes Relevant At High Frequencies Over Longer Runs

  11. UTP Minimizes Induced Noise • UTP (Unshielded Twisted Pair) Can Be Optimized For Specific Tasks • Differential (Balanced) Signaling Ensures Environmental Noise Rejection • Differing Twist Rates Minimize Crosstalk Between Pairs • Twist Pitch Is Vital In Fixing The 100Ω Characteristic Impedance • Bandwidth Up To 250MHz Per Pair (Cat6) • 100MHz Per Pair Cat5e • 10Base-T, 100Base-TX, 1000Base-T

  12. “It is difficult to get a man to understand something when his job depends on not understanding it.” - Upton Sinclair What Does “Base-T” Mean?

  13. From StarLAN To HDBase-T • Local Area Network Technology Standards Of The 1980’s Included StarLAN and LattisNet • IEEE Worked To Standardize Physical Layer Attributes Of 10 Mb/s Networks • Names Derived From Physical Media • BASE Denotes Baseband Transmission • Signals And Systems Whose Range Of Frequencies Is Measured From Close To 0 Hz To A Cut-off Frequency, A Maximum Bandwidth Or Highest Signal Frequency • T Denotes Twisted-Pair Carriage

  14. “All truths are easy to understand once they are discovered; the point is to discover them.” - Galileo Galilei HDMI Beyond 50-feet

  15. TMDS Over Dual UTP • Dual Cat-x Connectivity • One For TMDS – RGB and Clock • One For SCL/SCA I2C, Hot Plug, 5V Power, 5V Ground • No Fundamental Changes Are Made To The Signal • Equalization And Clock Reconstruction • Impedance Matching And Voltage Amplification • Carriage Distance Is Inversely Proportional To Signal Bandwidth • 60 Meters For 720P Content • 25 Meters For 1080p/60 • 20 Meters For 1080p With 10 Or 12 Bit Color Depth Content

  16. “Our main business is not to see what lies dimly at a distance but to do what lies clearly at hand.” - Thomas Carlyle HDMI Beyond Imagination

  17. HDBaseT Alliance And Standard • Established In 2010 By LG Electronics, Samsung Electronics, Sony Pictures, Valens Semiconductor • Working Openly To Create A Global Standard For Advanced Digital Media Distribution • HDBaseT 1.0 Standard Finalized In June 2010 • Deals With Video Control Signals And The Reconstruction Of Video Clocks. • HDBaseT Standard Includes Provisions For Power • HDBaseT Standard Will Support Up To 8 “Hops” Of 100 Meters Each

  18. Designed For 5Play “HDBaseT Is A Connectivity Standard Which Consolidates High Throughput, Unidirectional, HDCP Protected, Uncompressed High Definition Digital Multimedia With Bidirectional Data Networking Over Standard Cat5e/6 Structured Cabling.”

  19. Breaking Down HDBaseT • Asymmetrical Design Supports Up To 10.2GBs Downstream and 100MBs Upstream Data Transfer • Scales To 20GBs For Future D4K Applications • Allows For Support, Over A Single Cabling Infrastructure Of: • Uncompressed AV With High Bandwidth Downstream Throughput, Characterized By Low Latency Service Time for Mesochronous Streams, Complete With Associated Controls • Bi-Directional Data Exchange At 100MBs
