How Does This Affect You?
  • The digital transition is complicated the more
    you know, the more you can help your customers
  • Over 50 of HDTV owners dont know that they need
    HD service to get HD
  • Over 50 of consumer returns are due to product
    complexity Stan Glasgow, President of Sony
    Electronics (HDTV forum 2006)

What Do Consumers Want?
Easy Set-up 3
Why Digital?
  • Access to Content
  • Viewing premium HD content requires digital
    interface with content protection
  • Not possible to truly encrypt analog
    (authenticate, encrypt revoke)
  • Better Quality
  • Content (DVD, satellite, digital cable, ATSC,
    etc.) is natively digital
  • Digital interface maintains perfect fidelity all
    the way to the display audio DAC
  • Also best quality video audio processing
  • Simple Lower Cost
  • Single cable with automatic plug play
  • Costly analog conversion electronics not required

  • HDMI High-Definition Multimedia Interface
  • The first and only digital interface for Consumer
    Electronics that can carry
  • Uncompressed high-definition video (support for
    1080p since inception)
  • Compressed or uncompressed multi-channel audio
  • Smaller connector
  • YUV color space support
  • Intelligent format command data

HDMI Overview
  • HDMI has become the de facto digital connectivity
    standard for consumer electronics products.
  • HDMI delivers the highest-quality audio and video
    signal over a single cable
  • Over 450 manufacturers have adopted the
    technology and analysts expect nearly 60 million
    HDMI-enabled devices to ship in 2006, growing at
    nearly 120 per year
  • HDMI continues to evolve to meet the changing
    market needs
  • Version 1.3 of the HDMI specification doubles
    overall bandwidth to deliver even higher quality
    video and audio signals.

1.3 - Next Gen HDMI Performance
  • Specification released June 2006
  • First 1.3 enabled products (Sony PS3) will begin
    shipping in November
  • Maximum Bandwidth Increased by Over 2x
  • From 165 MHz (4.95 Gbps) to 340 MHz (10.2 Gbps)
  • Benefits of Greater Bandwidth
  • Higher resolution, greater DPI displays
  • Higher refresh/frame rates
  • Increased color depth (up to 48 bit/pixel RGB)

1.3 Next Gen HDMI Performance
  • Maximum Audio Performance
  • 1.3 adds support for Dolby TrueHD DTS-HD Master
    audio formats
  • Approved formats for Blu-ray HD-DVD
  • Lossless formats brings exact same digital
    surround experience as original theater movies
  • Automatic Lip Sync timing compensation
  • 1.3 enables automatic correction for most common
    audio/video sync issues
  • Mini connector option for portable devices
  • Camcorders, digital-still cameras, etc.

BluRay and HD-DVD
  • Do I need HDMI 1.3 to get native 1080p support?
  • No- HDMI 1.0 supports 1080p. HDMI 1.3 is needed
    for deep color (ex. 36 bit/pixel) support.
  • Do I need HDMI 1.3 to get Dolby True HD or DTS-HD
    Master support?
  • No- players can perform decoding and send over
    HDMI 1.x as uncompressed multi-channel PCM audio
    to AV receiver.
  • But- expect next gen AV receivers to add Dolby
    TrueHD and DTS-HD decoding for greater
  • HDMI is specifically designed to be backwards
  • Look for the feature, not the spec revision!

Video Control and Configuration
  • Video Discovery EDID
  • Source knows Sinks supported video formats,
    aspect ratios of DTV
  • User does not have to setup DVD player, Set-top
  • Active Video Stream Info AVI InfoFrame
  • DTV knows what video format, aspect ratio it is
  • User does not have to change DTV aspect

HDMI Compliance Testing
  • Compliance Testing Mandated by HDMI Adopters
  • Checks compliance with HDMI specification
  • Required for a product to bear the HDMI logo
  • Promotes compatibility between devices
  • Does not include HDCP testing
  • Authorized Testing Center (ATC)
  • Initial product testing must be done at ATC
  • First product in a category (sink, source,
    repeater, cable) from each company
  • Subsequent products can be self-tested by

HDMI A High Performance CE Technology
  • HDMI specification has potential for excellent
  • Perfect digital transmission of high resolution,
    uncompressed audio video on single cable
  • Capability of true plug play experience
  • Evolving innovations to meet market needs
  • As an open industry standard, HDMI enables
    manufacturers to differentiate through quality
  • Like any technology, not all products are created
  • Following are examples of incompatibility due to
    lesser product design and inability of some
    manufacturers to fully test validate their

HDCP How does it work?
A/V Receiver
DVD Player
Source Authenticates Downstream devices
Common HDMI ProblemRepeater Support
  • Consumer plugs HD set top box into HDTV via HDMI

Adding an A/V Receiver
  • Consumer uses HDMI A/V Receiver (available today
  • Common result No sound in receiver, no picture
    on TV

Problem Analysis
  • Customer assumes HDMI A/V Receiver is bad since
    system worked before
  • Results in returns, support calls, and customer
  • Actual Root Cause
  • HDMI source does not support HDCP repeater
    function, resulting in HDCP authentication
  • Proper Solution
  • Often a simple change to source firmware

Another Common HDMI ProblemSource Switching
  • User toggles TV input to HDMI input
  • but sees no picture

Set Top Box
DVD Player
Problem Analysis
  • Root Cause
  • Some TVs will not respond to HDCP authentication
    unless the HDMI input is selected
  • Some HDMI sources will attempt HDCP
    authentication for limited time, then give up and
    disable HDMI output
  • Such source will disable HDMI if TV does not
    switch to HDMI input within timeout period
  • Proper Solution
  • Revise source firmware to perform HDCP
    authentication forever with no timeout

HDMI Cable Issues
  • Some HDMI cables will fail with 1080p
  • Most common with longer (5m) lengths
  • Why?
  • Most HDMI cables are only tested to 720p/1080i
  • Devices do not automatically downshift
    resolution if cable transmission fails
  • SimplayHD cables are full 1080p verified
  • Tests with worst case source signal
  • Verifies signal integrity up to 1080p, exceeding
    HDMIs strictest Category 2 cable requirements
  • Spend your cable budget wisely on interconnects
    that are 1080p-ready

Whats Really 1080p?
  • Wheres the 1080p content?
  • PlayStation3 1080p, 36 bit/pixel color
  • Most BluRay and HD-DVD movies are native
  • Samsung BD-P1000 Blu-ray player
  • Toshiba HD-E1 HD-DVD player
  • HTPCs support 1080p now
  • First 1080p TV sets only accepted 720p/1080i HDMI
    input and upscale it internally
  • 720p scaled up to 1080p
  • 1080i de-interlaced for 1080p
  • HDMI cable is only running 75MHz, longer cables
  • More and more 1080p TVs are supporting full 1080p
    native input on HDMI
  • Must read the TV spec carefully (expect future
    Simplay HD program to make it easy to identify)
  • HDMI cable is more critical, especially 5m and

Simplay Certified Cables

  • PR186BP (12 feet), 119.99
  • These are installer cables, retail models will
    also be certified.
  • TTE 1 meter cables
  • Freeport 1 and 2 meter cables

What If I Need a Longer Cable Run?
  • Cable equalizing/amplifying devices are available
    on the market, and typically work well
  • Some HDMI switch boxes (ex. Radiient) act as
    boosters as well
  • If you use these
  • Put the booster closer to the display than the
    video source if you have different length cables
  • New products that convert HDMI to CAT6 wiring,
    useful for pre-wiring in new construction
    (Gefen, Extron)
  • There are also optical cables that work convert
    electrical signals to light pulses
  • Very long, but expensive

Other Cable Issues
  • Make sure your cable vendor uses connectors from
    the approved list
  • HDMI website lists tested approved connectors
  • http//
  • Some cables with large plug overmold are not
  • May not fit in devices with side-by-side HDMI
  • Interferes with screwheads that attach connector
    to backplate
  • HDMI LLC is cracking down on violations

Industry Support for Simplay HD
Stephen H. Wildstrom / April 17, 2006
  • NEEDED COMMON SENSE. There's one glimmer of
    hope for consumers. Silicon Image (SIMG), a
    company that helped develop the HDMI standard,
    has set up a subsidiary called Simplay to test
    compatibility. Its system should be in place by
    the time high-def DVDs are available. Then you'll
    know that a DVD player will work with an HDTV set
    as long as both bear the Simplay logo.
  • Simplay should be a big step forward. But for
    HDTV to succeed in the mass market, content
    owners, service providers, and equipment makers
    need to impose a sanity check on content
    protection. If preventing piracy trumps all other
    considerations and makes it too hard for people
    to use these expensive new systems, the market
    will never reach its potential.

Rely on SimplayHD
  • Marty Zanfino, Director of Product Development,
    Mitsubishi Digital Electronics America
  • Mitsubishi has decided to have all of its
    products with HDMI inputs and/or outputs to be
    SimplayHD certified. We felt that, being a
    premium brand, this added assurance is the type
    of due diligence that our customers expect from
    us, and is well worth the effort.
  • Steve Samson, VP of design and engineering for
    Tweeter (a high-end US CE retailer)
  • The compatibility testing that Simplay Labs
    offers gives us confidence that SimplayHD
    verified products will work seamlessly together
    for our customers

  • The executive summary is that the Toshiba player
    appears to be able to handle only two of the many
    different allowed TV power-on/active states 1)
    when TV is fully on with the HDMI input selected
    and fully active, 2) when HDMI signals
    effectively indicate the cable has been
    physically disconnected. The player goes into the
    Error state whenever it sees the TV's HDMI port
    in any other kind of standby or interrupted
    state, which unfortunately, are states seen in
    the majority of the TVs on the market.
  • A big thanks to SimplayHD for sharing its test
    results with us.
