15. Video Formats
HDMI explicitly specifies a complete list of DTV Video formats
Defined in EIA/CEA-861B
SDTV (NTSC/PAL), EDTV & HDTV
Interlaced 480i to 1080i
Progressive 480p to 1080p
HDMI also allows any other video format
PC formats: VGA, SVGA, XGA…UXGA
Wide PC formats (common on Plasma monitors)
Any other VESA-defined or vendor-defined format

16. Audio Formats HDMI supports a complete range of Audio formats
Compressed formats
Dolby Digital, Dolby Digital EX, DTS, DTS ES, …
Uncompressed audio
Up to 8 channels, up to 192kHz, up to 24 bits
DVD Audio and SACD supported
CD-quality audio is “base level” and will always be available on any audio-capable product
2-channel, 16-bit at 32, 44.1 or 48 kHz

17. Audio & Video Format Intelligence
Source device receives the display’s supported audio/video formats
Sink device receives audio/video format info on every frame
DVD : Widescreen Format
16:9 Display w/ no Intelligence
16:9 Display with Intelligence

18. HDMI Consumer Electronics Control
Allows user to control all HDMI devices with TV remote
Can control DVD player by pointing remote at the TV
Enables high-level functions such as “one-touch play” :
Automatically… Turns on TV
Press Play on DVD
And then… Plays DVD
Automatically… Turns on A/V Rcvr
Automatically… Switches to correct input (from A/V Receiver)
Automatically… Switches to correct input (from DVD player)

23. HDMI Compliance Testing
Compliance Testing Mandated by HDMI Adopter’s Agreement
Promotes compatibility between devices
Checks compliance with HDMI specification
Required for a product to bear the HDMI logo
Authorized Testing Center
Initial product testing must be done at ATC
First product in a category (sink, source, repeater, cable) from each company
Subsequent products may be self-tested by manufacturer
Current locations:
Silicon Image, California, USA
Matsushita, Osaka, Japan
Philips, Cannes, France
See for specific contact information

24. New Market Demands Video Audio
Greater color depth – beyond 24bpp
Higher resolution – beyond 1080p
Faster refresh rates – beyond 60Hz
Audio
Near lossless quality = higher bandwidth
Dolby TrueHD
DTS HD
HDMI will continue to meet market demands

28. Achieving Full Interoperability
Rapid introduction of HDMI has led to interoperability failures as manufacturers rush to market with a range of implementation quality
Many failures are related to poor HDCP implementations with no way of testing
Ad hoc testing of HDCP not sufficient
US-based Consumer Electronics Association plug-fests have revealed numerous interoperability issues
Products already at retail with no chance to correct

29. Full Interoperability
