Next Big Thing – USB Type-C and Video

The State of Interface Technologies in 2004

Dell 2004 Desktop

In 2004, desktops were the largest PC market enjoying WW shipments of 119mil units (3X more than notebooks)

Dell enjoyed the highest PC market share (16%)

There were no smartphones or tablets but Apple already selling 10mil iPod’s worldwide

USB 2.0(480Mbs)

>> Fast Forward to 2014

Landscape has Completely Changed

Dell 2014 Desktop

Apple MacBook Pro

In 2014, notebook have well

surpassed desktop PC shipments

But tablets are projected to ship

256mil units more than notebook or

desktop PC’s (will surpass all PC’s by

2015)

Smartphones are the commanding

category leader with 1.2bil units in

2014

More high-res video-enabled devices

• Demand for high-quality video (4k UHD and higher)• VR/AR• Increased adoption of USB-C and Thunderbolt 3• Mobile device docking

Data Source: VESA Org and HDMI Forum

DisplayPort 1.4 Overview

✓ The VESA DisplayPort Standard, Version 1.4, was released on February 23, 2015

✓ Added new features and capabilities such as Display Stream Compression (DSC), Forward Error

Correction (FEC) and enhanced Multi-Stream Transport (MST) feature

✓ Backward compatible, offers new optional features

✓ New Silicon supporting HBR3 is shipping and new features are under development

✓ DisplayPort adopted by Alt-mode USB Type C, MyDP, eDP, DockPort, Thunderbolt, VR/AR

HDMI 2.1Overview✓ Higher Resolution & Faster Refresh Rate

✓ 8K60: 8K delivers a super-immersive viewing

experience & 60Hz enables smooth and sharp

viewing of content with high-speed action

✓ 4K120: Ultra fast-motion UHD images are crisp and

razor sharp - especially sports, action movies, high-

performance gaming and VR

✓ Multiple resolution support includes 5K and 10k

resolutions for PC displays, digital signage,

surveillance, and various commercial and

industrial AV solutions

✓ Dynamic HDR: Movies and other content will be able

to take advantage of HDR’s expanded contrast

ranges, brightness levels, and heightened levels of

detail—and now have them optimized on a scene-

by-scene or even a frame- by-frame basis

✓ 48G Cable: 8K video with HDR, 48Gbps, Type A, C

and D, and HDMI Ethernet

✓ eARC: eARC supports the most advanced audio

formats such as object-based audio providing an

immersive multi-dimensional experience and

enhanced audio detail and depth

released on Sept 22, 2014

✓ Enables the use of the USB Type-C interface for

DisplayPort

✓Alternate Mode functional extension of the USB Type-C

interface

✓ Thin profile suitable for both ultra portable devices and

larger devices

✓Reversible plug orientation & cable direction

✓USB 3.1 Gen 2 (10Gbps)

✓USB Power delivery, up to 100 watts

USB-C

HDMI Over USB Type-C Overview

✓ “HDMI 1.4b Alt Mode on USB Type-C Spec” first released Sept, 2016

✓Current HDMI Alt Mode Spec: Version 1.0a, (January 17, 2017)

✓ Follows Alt Mode USB Type-C specification requirements.

✓USB Power Delivery (USB PD) enables Alt Modes with mechanisms to

discover, enter and exit Alternate Modes.

✓HDMI 1.4b Alt Mode spec only applies to 1.4b Sources and Cable

Adapters. There is no Alt Mode spec for HDMI Sink or HDMI 2.x currently.

✓Devices that require an Alt Mode must support USB PD

✓HDMI Type-C Cable Adapters require contains a “Billboard device”

✓ To Notify user when switching to HDMI Alt mode is unsuccessful

✓ Cable Mechanical Tests

✓ Cable Parametric Tests

✓ Cable Additional

Electrical Performance

Tests

✓ Type-C Connector Tests

✓ Physical layer (BMC-PHY)

Tests

✓ Protocol layer (BMC-

PROT) Tests

✓ Power state (BMC-POW)

Tests

✓ HDMI Over Type-C Source Tests:

✓ HDMI 1.4b Source Tests

✓ HDCP Tests

✓ Alternate mode device does not receive an Enter or Exit

Alternate Mode command

✓ Host does not support PD so does not look for alternate mode devices

✓ Host finds alternate mode device, but does not support this particular device

✓ Alternate mode device presents either an equivalent USB

function and/or USB Billboard Device interface to the USB stack

✓ Billboard Device provides the OS with information about the alternate mode device that it can be use to inform the user that the host does not support the alternate mode

Failure to find an Alternate Mode

Summary

✓DP1.4 and HDMI 2.1 provide over 50%+ increase in performance

among other improvements

✓ DisplayPort and HDMI Over Type C is game changer for small

form factor and portable products.

✓DP 1.4 and DisplayPort Alt-mode certifications are available
