Let s all be Green
Objectives Digital Video Signals What will the PC give us in the future How will I make these signals work in systems? Will there be one format that wins?
Digital Video Signals
USB Serial port replacement scheme designed to connect: Mouse, Keyboard, Scanner, Printer, Digital Camera, MP3 Players, etc High Speed USB 2.0 up to 480 Mbs Computer (host) to device communication Computer is always involved Medium distances Under 30 Wireless/On-The-Go is here and being deployed
Firewire IEEE 1394 Firewire is a trademarked name by the Apple corporation Sony has a version called I-link A consumer standard for high-speed digital transfer Original speed of about 400 Mb/s Current capability of about 800 Mb/s to 1.6 Gb/s 1394 over Coax, Fiber & CAT 5 Device to device communication Computer is not required Signals are Compressed at approx 5:1 Distances Original Distance of under 30 Can be extended Late Breaking News S3200 Standard ups the speed to 3.2 Gb/s
SDI (Serial Digital Interface) Transmit Broadcast Quality Video Digitally Composite Component Very long transmission distances Up to 1000 with Extron RG-6 cable Applications Broadcast, Production and Post-production Introduced in 1986 SMPTE 259M
HD-SDI (High Definition Serial Digital Interface) Transmit Broadcast Quality HDTV Digitally Component 720P, 1080i, 1080P Long transmission distances Up to 300 with Extron RG-6 cable Applications Broadcast, Production and Electronic Cinema Introduced in 1995 SMPTE 292M
DVI
Why? Digital Link
Digital Visual Interface
What makes it work? 1024 x 768 What is your native resolution? Ok, I ll output that. Monitor contains none of the electronics to scale, resize, or manipulate the image.
TMDS Transition-Minimized Differential-Signaling A video signal transmission method Developed by Silicon Image Inc Marketed as PanelLink Can only be transmitted 5m or 15ft Can be extended
Digital Video & The PC TMDS-Single Link EDID (Extended Display Identification Data) VESA Standard Communication protocol that identifies the display type to the PC or graphic card DDC (Display Data Channel) VESA Standard Display to PC communication
Digital Video & The PC TMDS Single Link-165 MHz Video & aux data transmitted across three data channels: C0, C1, C2
Digital Video & The PC TMDS Dual Link 330 MHz Dual Link simply Doubled the Red Green and Blue Signals being sent
DVI Connections
HDMI High Definition Multimedia Interface
HDMI High Definition Multimedia Interface Digital Video RGB or Component Digital Audio Can output Analog Stereo if required in system HDCP Hardware supports Software Commands Control Optional One Cable Connection
HDMI via TMDS Three high speed Video/Audio channels Data Rates to 10.2Gbps Carries from 8 to 16 bit RGB/YCbCr video components Digital Audio and Control
The Promise of HDMI Simple plug n play connection Only one cable required Replaces up to 15 separate cables Improved run distance Specification has not changed-cables are better Intelligence between Devices Hot Swappable Connections

HDMI HDMI System Architecture Basic Source Sink Integrated Repeater Cable
HDMI - Basic Source A Source is expected to read the Sink s E-EDID via the DDC channel and deliver only the audio and video formats that are supported by the Sink.
HDMI - Basic Sink Once the 5V power is established from a source the Sink will reply within 20msec with E-EDID information to the Source of it s capabilities. This reply can also include vendor specific commands.
Basic HDMI System Display HD-DVD HDMI Cable HDMI Cable Satellite Receiver
HDMI - Repeater Repeater Defined as a device with one or more HDMI inputs, one or more HDMI outputs, and a Re-Transmission Function Functions Repeat 1 In/1 Out Switch Multi In/1 Out Distributor 1 In/Multi Out (1 Output Active) Duplicator 1 In/Multi Out (All Output Live) Combinations of the 4 are allowed Acts as a Traffic Cop in the System
Integrated HDMI System Display HD-DVD HDMI Cable HDMI Cable Repeater (Surround Receiver)
HDMI Audio Support The complete range of audio formats: Compressed formats: Dolby, DTS, etc. Uncompressed audio Up to 8 channels, up to 192 KHz, up to 24 bits DVD audio CD-quality audio (base level) 2-channel, 16-bit at 32, 44.1, or 48 KHz Audio packaged in audio sample packets
Consumer Electronics Control: CEC What is it? Provides high-level control functions between all devices in the system CEC is optional Separate line in the digital link connection CEC has its own protocol and QoS spec Currently provides 14 features Supported from Device Remotes IF fully implemented
CEC Enabled System 3) Turns on TV 1) Press Play on DVD 5) And then Plays DVD 2) Turns on A/V Rcvr 4) Switches to correct input (from DVD player) 4) Switches to correct input (from A/V Receiver)
HDCP High-bandwidth Digital Content Protection Authentication rivals TCP/IP SSL Key element attracting Hollywood content All elements map into the DVI specification System must be designed to pass this information from Source to Sink Cannot be bypassed Would your customer like Not Seeing High Definition Material on their system?
