Native HDMI over Type-C Alternate Mode | Cypress Semiconductor

はじめに

HDMI® over USB-C™

HDMI is available today over USB-C, but it is costly
Current solutions require DisplayPort™ Alternate Mode, a DP to HDMI converter and VBUS DC/DC converters

HDMI over USB-C Alternate Mode is a simpler, cost-effective solution
Native HDMI from new HDMI enabled sources, over USB-C pins
Full HDMI 1.4b functionality without DP to HDMI converters or DC/DC converters

HDMI Alternate Mode is easy to use, and HDMI is a worldwide standard
Spec released by HDMI SIG on Sept, 2016
Combines the most popular connectivity solutions, USB-C and HDMI, together
Enables a simple USB-C to HDMI cable with no adapters or converters

Cypress Enables the Industry's First Native HDMI over USB-C Solution

Based on Cypress EZ-PD™ controllers, next-generation laptops, smartphones, tablets, digital cameras and other HDMI sources with USB-C connectors can connect directly to HDMI sinks, such as HD and 4K monitors, TVs and projectors, using only a simple USB-C to HDMI cable.The EZ-PD controllers support the new native HDMI Alternate Mode for USB Type-C, along with USB Type-C standard support for audio, video and data protocols, as well as USB Power Delivery (PD) for fast charging.

All HD and 4K televisions include HDMI connections, but connecting source devices previously required adapters or converters that did not enable all native HDMI features.With the Cypress HDMI alternate mode solution, manufacturers can now utilize native HDMI features via USB Type-C connectors.
