HDCPWhat is it?

• High-bandwidth Digital Content Protection (HDCP)
• HDCP is a content protection technology developed
  by Intel and available for HDMI devices
• HDCP is designed to be used when distributing
  premium HD content.
• All HD cable and satellite set-top boxes require
  HDCP for HDMI connection

Cables andConnectors

• 19-pin (type A) small form factor plug and jack
• Cables typically 2 to 5 meters

34
Installation Techniques
35
Installing HDMI

• Equipment interconnection
• Cables
• Switches, Splitters, Extenders
• DVI lt-gt HDMI interoperability
• Common Integration Issues
• Different versions of HDMI

36
Equipment Interconnect

• HDMI designed for point-to-point interconnect
• Not a bus or network

37
Equipment InterconnectCables

• Cable always has male plug
• Equipment always has female jack
• Maximum cable length NOT specified in standard
  (only the cable performance)

ALWAYS test cables with actual equipment in shop
prior to installation!
38
Equipment Interconnect Switches and Splitters

• Many devices available
• Remote controllable via RS232 or IR
• HDCP compliant (input to output)
• Always test with equipment you plan to use,
  particularly for HDCP handshaking

39
Equipment InterconnectHow to Choose a Switcher
What Do You Need?

• Switch multiple inputs, no processing
• Typically up to 4 inputs
• Only HDMI input and output connectors
• Acts as active cable booster
• Beware switchers without power are not HDMI
  compliant
• Switch multiple inputs enhanced video/audio
  processing
• Same as above, but adds video/audio processing
• Apply high quality video processing
  (deinterlacing, upscaling, frame rate conversion,
  etc.)
• Combined DVI and audio inputs into HDMI output
  (or vice versa)

40
Equipment InterconnectHow Do You Choose a Cable
Extender

• Cable extenders come in two types passive and
  active
• Passive, lower cost
• Often no dedicated power
• Use equalizer to boost signal
• Does not fully reset the signal
• Good for shorter extensions (3-5 meters)
• Active
• Requires dedicated power
• Fully decodes, retimes and resets the signal
• Capable of longer extensions (5-10 meters)

41
Equipment InterconnectHow to Choose a Splitter

• HDMI/HDCP signals can be split
• HDCP supports up to 128 simultaneous displays
• Unlike analog, HDMI cannot simply be fanned out
• Requires active electronics to decode, split and
  retransmit
• Required to decode, mirror
• Output from some splitter boxes are the same
  format as the input (2-480i, 2-720p, etc.)
• Beware splitters with no power supply

42
DVI lt-gt HDMI Interoperability
DVI-D
HDMI

• HDMI is backward compatible with DVI
• HDMI electrically compatible with all DVI-D
  signals
• DVI-D does not provide/support CEC or audio

43
HDMI lt-gt DVI Interoperability

• Wide selection of DVI - HDMI adaptors and cable
  to allow easy equipment interconnect

44
HDMI -gt DVI Interoperability

• HDMI output provides digital video only
• Audio channels provided separately
• No CEC

45
DVI -gt HDMI Interoperability
Digital video only provide from DVI source
Audio channels provided separately No CEC
46
HDMI lt-gt HDMI Product Interoperability

• Cannot ship products unless they pass compliance
  testing from HDMI Authorized Test Centers
  (operated by HDMI Licensing, LLC)
• HDMI Test Centers currently do not test for HDCP
  compatibility
• Some early implementations of HDMI were not
  compliant with HDCP spec
• HDMI LLC actively working with manufacturers to
  enforce compliance

HDCP compliance test specification currently
being developed by Intel

Frequently Asked Questions of HDMI

• Do only the most recent versions of HDMI support
  1080p

Answer HDMI has always supported 1080p
resolution, starting from version 1.0 in 2002

• Do you need a new version of HDMI to play Blu-ray
  and HD-DVD content in high definition?

Answer All versions of the HDMI specification
support HD-DVD/Blu-ray content in high definition

• Why doesn't HDMI support high-end digital audio
  standards?

Answer From its creation, HDMI was specified to
carry 8-channels of 192 KHz, 24-bit uncompressed
audio. In addition, HDMI can carry any currently
available compressed audio format, such as Dolby
Digital and DTS. It now supports new compressed
digital audio formats such as Dolby TrueHD and
DTS-HD
53
Frequently Asked Questions of HDMI

• Do I need to worry about all the different
  versions of HDMI?

Answer HDMI is enabler of technology for
manufacturers. HDMI does not require a
manufacturer implement any specific features.

• Manufacturers decide which features to implement.
• Features that take advantage of HDMIs
  capabilities are at the sole discretion of the
  individual manufacturer.
• Shop for functionality, not a specific HDMI
  version.
