HDMI 1.4 devices going to be backwards-compatible with older HDMI (v.1.0 – 1.3) devices?
Devices built to the HDMI 1.4 specification will be fully backwards-compatible with existing HDMI devices and their features. Most of the new features introduced in HDMI 1.4 will require a new HDMI chip to enable, and cannot be upgraded via firmware. TDA19989AET is a very low power and very small size High-Definition Multimedia Interface (HDMI) v. 1.4 transmitter. It is backward compatible DVI 1.0 and can be connected to any DVI 1.0 and HDMI sink. There is no chance whatsoever of there being backwards-compatibility. The main point is that the new system. This really depends on what I decide to add to each release, but I’ll only make changes that require changes. The Automotive Connection System will also employ a new class of cable, the Standard Automotive HDMI cable, which is designed specifically for automotive use. All of the other new HDMI 1.4 features will be compatible with the existing categories of cables.
